I've proven that in basketball that buying points is an absolute waste of your money....doesn't matter the few times you "saved your *ss" with the points, but the juice that you pay on the 85% of the time it DIDN'T MATTER in basketball, YOU WASTE MORE ON THE JUICE THAN YOU "SAVE" BY BUYING THE POINTS.  BUT that is in basketball and the point values are linear at 1, 2 and 3.

CHECK OUT THE BASKETBALL STATS IN NBA AND NCAA FORUMS.

------------------------------------------------

Here it is, the FULL 7 NFL REGULAR SEASON STATS that Covers.com offers with FULL STATS AND PROBABILITIES on BUYING 1/2 POINT TO 3 OR 7, FG or TD:

For your understanding, I took ALL THE GAMES THAT HAD ORIGINAL SPREADS "NEAR" OR ON 3 OR 7.

-For games that were originally -3.5, it was bought down to -3 to make loss into push.
-For games that were +2.5, it was bought to +3 to make loss into push.
-For games that were -7.5, it was bought down to -7 to make loss into push.
-For games that were +6.5, it was bought to +7 to make loss into push.

-For games that were ON 3 or 7, 1/2 point was bought on ONLY 1 of the 2 teams as you would NOT buy 1/2 point on both sides. Either way, doesn't matter WHICH team you picked, but that you bought the half point on the game that was ON the number FOR THE WIN instead of a PUSH.

SO...WAS BUYING 1/2 POINT ON GAMES NEAR OR ON 3 OR 7 WORTH IT?!?!?

Using the 7 NFL Regular Seasons worth of data and the sample size of 763 games that we could have bought 1/2 a point to or off of 3 or 7 points:

31 bets would have pushed instead of lost, for a savings of $120 per bet for a total of $3,720.

27 bets would have won instead of the original push for an extra winnings of $100 per bet for a total of $2,700.

By buying 1/2 a point on games near or on 3 or 7 would have had a total result of $6,420.

763 total games bet on minus the 58 games where the 1/2 point affected the outcome of the game from a loss to a push or an original push to a win equals 705 bets where THE 1/2 POINT DID NOT MATTER.

On those 705 bets we would have Lost $10 more than just taking the original -110 bet OR won approx. $10 less than had we put the $120 on the original -110 spread.

705 bets X $10 = $7,050 lost on the 10% juice

$6,420 "savings" < $7,050 lost on juice.

CONCLUSION:  BUYING THE HOOK OF 1/2 A POINT ON SPREADS AROUND 3 OR 7 WOULD HAVE LOST A LITTLE BIT OF MONEY AND WAS PRETTY MUCH JUST A WASTE OF TIME.

ALTHOUGH IT MAY HAVE GOTTEN 7.6% MORE WINS, THE CALCULATIONS DON'T LIE....IT REALLY DIDN'T HELP AT ALL, BUT RATHER WOULD HAVE LOST A SMALL $630 OVER THE STRETCH OF BUYING 1/2 A POINT 763 TIMES.

ADVICE: JUST WORK ON HAVING OVER A 52.5% ON -110 ORIGINAL SPREADS TO MAKE MONEY.  IF YOU FEEL YOU NEED TO BUY THE 1/2 POINT, OR ANY AMOUNT OF POINTS FOR THAT MATTER,....WHY ARE YOU EVEN BETTING ON THE GAME?!?!?

THERE ARE BETTER BETS ON THE BOARD

WINNING OVER 52.5% OF BETS ON -110 ORIGINAL SPREAD ODDS CALCULATIONS:

Winning 52.5% of 1,000 bets is 525 wins x $100 = $52,500

Losing 47.5% of 1,000 bets is 475 losses x $110 = $52,250

$52,500 winnings - $52,250 in losses = $250 in PROFIT

Pick bets that you are sure on.  If you feel you need to buy the "hook" to win, don't bet on that game.  Don't bet just because it is on TV,....then you are Paying for Entertainment.

THE REAL REASON ANY OF US GOT INTO GAMBLING:

TO MAKE MONEY AND PROFIT....NOT JUST FOR ENTERTAINMENT

...BUT TO EACH HIS OWN

BEST OF LUCK EVERYONE

To me, the most important thing in betting is money management. It's more important than picking a winner.

Does this put the whole buying the 1/2 point to the "KEY" numbers of 3 and 7 to rest?  Or are people who buy that 1/2 point Psychic where they can pick BETTER THAN the 7.6% of games where that 1/2 point will even matter, just to make a profit overall?

Do all the stats and numbers and logic look right?  Did anybody see any mistakes in my analysis?  Always open to hearing if I did something wrong or miscalculated or didn't explain something well enough.

Let me know guys, I think this is some great insight into the myth of buying points near 3 and 7 in football.  I hope it was helpful and insightful.

I will also add that many sports books understand how people like to buy to 3 and 7 in football.  Many books understand that buying down on favorite lines of -3.5 and -7.5 and buying up on dogs of +2.5 and +6.5 is of WAY HIGHER DEMAND than people buying 1/2 point on -2.5 or -6.5 down to -2 or -6 and buying 1/2 point on +7.5 and +3.5 up to +4 and +8.....

sooo.....they raise the rate and jack up the juice.  At least at my sportsbooks, lines of -3.5, -7.5, +2.5 and +6.5 cost MORE than the usual 10 cents for the 1/2 point as compared to buying the 1/2 point on -2.5, -6.5, +3.5 and +7.5.

Sportsbooks know the demand and charge accordingly, so even if you hit the average of 7.6% of bets being affected by the 1/2 point, you would also have to add in the HIGHLY TAXED JUICE for those 1/2 points that EVERYBODY and their mothers want to buy.

So in my example where I compared the money "SAVED" on the bets that WERE affected against the money LOST on the ADDED JUICE of the 92.4% of the bets where the 1/2 point did NOT MATTER,....the disparities would have been even greater if you calculate in paying MORE THAN 10 cents juice for the in-high-demand 1/2 point.

In the example of 6.7% of all bets being affected, there was a $630 LOSS of money.  Understand that that loss would have been even greater had the sports books charged MORE.

I cancel post number #5 in light of THECLAW helping me look at my data in another forum:

After theclaw got me thinking.....let's assume a gambler IS a 50/50 gambler.  Here is my example of a 50/50 gambler buying original lines at -110 vs buying 1/2 point at -120 using the 763 games where he could have bought ONTO or OFF of 3 or 7:

50/50 gambler betting original spreads on the 763 games at -110 odds:


763 minus 27 original pushes = 736 games that were NOT pushes

736 divided by 2 = 368

368 wins x $100 in winnings per game won = $36,800

368 losses x $120 in losses per game lost = $44,160

$36,800 - $44,160 = $7,360 in TOTAL LOSSES

----------------------------------------------------------------------------

50/50 gambler buying 1/2 point on the 763 games at -120 odds:

763 minus 27 original pushes = 736 games that were NOT pushes

736 divided by 2 = 368

(368 wins + 27 pushes to wins) x $100 in winnings per game = $39,500

(368 wins - 31 losses to pushes) x $120 in losses per game = $40,440

$39,500 - $40,440 = $940 in TOTAL LOSSES

$7,360 in losses betting original spreads > $940 in losses buying the 1/2 point onto or off of 3 or 7

IN CONCLUSION:  When you compare a 50/50 bettor betting on original spreads at -110 as opposed to buying 1/2 point on those SAME 763 games where you could buy ONTO or OFF of 3 or 7, IT DID SAVE THE BETTOR $6,420 OVERALL.

POINT BUYING DID SAVE THE 50/50 GAMBLER MONEY, BUT STILL NOT ENOUGH TO MAKE A PROFIT.

MY VOTE IS: BUYING THE HOOK, OR 1/2 POINT ON GAMES NEAR OR ON 3 OR 7 IS BENEFICIAL TO YOUR BANKROLL.

----------------------------------------------------------------------

I KNOW I HAVE BEEN ALL OVER THE BOARD WITH THE NFL DATA AND CONCLUSIONS!  THIS HAS BEEN A WORK IN PROGRESS AND STILL IS A WORK IN PROGRESS.

THANK YOU TO THECLAW FOR MAKING ME THINK ABOUT MY DATA!  IT'S PROVEN HELPFUL IN THE FULL ASSESSMENT OF BUYING THE HOOK IN NFL FOOTBALL.

PLEASE!  IF YOU SEE ANYTHING IN MY THREADS ON POINT BUYING THAT IS QUESTIONABLE, PLEASE QUESTION IT!  LIKE I SAID, IT IS A WORK IN PROGRESS!

After everything I just said in post #10, I DO want to re-iterate that it DOES RELY on what your book is charging you for that 1/2 point also.  A guy in another thread said that his book charges at least -125 for that 1/2 point around 3 or 7...at least the CRUCIAL 1/2 point on -3.5, -7.5, +2.5 and +6.5 and NOT the -2.5, -6.5, +3.5 and +7.5.

Adding the extra 5 cents or more into the equation/example could change things....well obviously it DOES hurt the amount saved,...but possibly not enough yet to say that buying points was NOT beneficial as opposes to just betting the original lines with a 50/50 gambler.


Our God Vegas and his many minions understand how gamblers work and OBVIOUSLY buying the 1/2 point around 3 and 7 is in WAY higher demand than anywhere else, and so they DO charge more for THOSE 1/2 points than anywhere else.

Again, please comment if you see any questionable data or thoughts...this still is a work in progress.  Mona Lisa wasn't finished until she had her lips painted on....

Mods, can you move this to the CFB or NFL forum?
Also, can you ask that this data isnt continually posted under new threads?  This is getting ridiculous. Its every day, to feed this guy's ego... I have read Natenberg enough for work, dont need someone jamming his understanding of statistics and probability down my throat on a gambling site that I visit for recreation.

Thank you

TexasD - thanks for the post, I really enjoyed it.

Let's look at it this way (and I am doing the calculations as I type this so not even sure what conclusion we will get at).

* There are 763 games with spreads near 3 or 7.

* I bet $100 on all the home teams.  My twin brother bets $100 all the away teams.  We both push 27 games.  The other 736, either I lose $10 or he loses $10.  So we lose $7,360 together.

* Now we both buy 1/2 point on all those 763 games.  In 705 games, we lose $20 per play (either I lose at -120 or he loses at -120).  So, that's a loss of $14,100.  In 31 games, we go 1-0-1 - so we win $3,100.  In 27 games we go 1-0-1, so we win $2,700.  So, we lose $8,300 together.

* So, do NOT buy the points.

* Is my math wrong?  Funny you got to -$7,360 for 1st part (but you got there incorrectly) - as you multiplied losses by -120 when it should be -110 (so it should be 1/2 amount) - but for me and my twin brother it is the -$7,360.

* Your math for 2nd part is CLEARLY wrong.  You have the dude playing 395 winners and 337 losers - which is 732 games.  But, 768-732 is 36 - and there were not 36 original pushes.

* Trust me, just think and do math like you and your twin brother bet opposite sides and if you both the hook, are you better off in end.

* Hard to explain why but your 50-50 assumption is flawed b/c that is 50-50 without the 1/2 edge.

* Agree?

Thank you  


I'm going to humor you once more by relying to your USELESS POSTS:

AS I HAVE STATED BEFORE, I POSTED IN IN THE NCAA AND NBA FORUMS BECAUSE FOOTBALL IS OBVIOUSLY (NOT SO OBVIOUS TO YOU) OVER AND NOBODY VISITS THE FOOTBALL FORUMS.

PLUS the NFL football data is a contrast to point buying in basketball and is interesting to contrast the two as MANY people buy to and off of 3 and 7 since they are KEY numbers.  Basketball is linear as the point values are 1, 2 and 3.

SECONDLY, AS I HAVE STATED BEFORE, I'M NOT "JAMMING IT DOWN YOUR THROAT." YOU CONTINUALLY CONTINUE TO CLICK ON THEM AS THEY OBVIOUSLY ARE NOT FOR YOU.

There ARE, and have been countless people who have benefited from this, thanked me for this, or CONTRIBUTED SOMETHING OF WORTH,...AS OPPOSED TO YOUR RIDICULOUS CLAIMS.

And now I digress back to ignoring your WORTHLESS POSTS.

Ohhh,....as to your "Thank you"....YOU ARE WELCOME

Thank you KVS23!!!! THERE WAS AN ERROR IN MY CALCULATIONS!!!!  I DID use the losses times $120 and not $110 as they should have been on a 50/50 guy betting -110 on original spreads.

Here is the CORRECT CALCULATIONS:

50/50 gambler betting original spreads on the 763 games at -110 odds:

763 minus 27 original pushes = 736 games that were NOT pushes

736 divided by 2 = 368

368 wins x $100 in winnings per game won = $36,800

368 losses x $110 in losses per game lost = $40,480

$36,800 - $40,480 = $3,680 in TOTAL LOSSES

----------------------------------------------------

AS FOR THE SECOND PART BEING INCORRECT,...I keep going over it and I think I hit it correctly.

"Your math for 2nd part is CLEARLY wrong.  You have the dude playing 395 winners and 337 losers - which is 732 games.  But, 768-732 is 36 - and there were not 36 original pushes."

That number should be 763, which is why you got 5 more. Plus there were ORIGINALLY 27 PUSHES ON THE ORIGINAL SPREADS, WHICH IN TURN, BUYING 1/2 POINT, CHANGE TO WINS.

The ORIGINAL 31 GAMES where a team lost by 1/2 point turn to PUSHES WHEN YOU ADD IN THE 1/2 POINT, therefore, when buying 1/2 point, there were 31 games that PUSHED INSTEAD OF LOST.

--------------------------------------------------------------------------------

And as to your calculations (and don't get me wrong, I'm not scolding you or arguing with you, but helping to talk our stats through and discuss whether we got them right or not):

The one thing that you didn't add in is that you can't use the 763 games in my sample in the way that you did, because THOSE 763 games were "framed" as ONLY BETTING 1 TEAM OF THOSE GAMES, so there is no betting on HOME AND AWAY on those 763 games...there was only 1 bet on either home or away and there was no other side.

Hopefully I didn't lose you on that, but I derived the NFL data by ONLY taking the "SITUATIONS" where a game was 1/2 point off of 3 or 7 OR DIRECTLY ON 3 or 7....We would ONLY BUY the half point on -3.5, -7.5, +2.5 or +6.5 and NOT the OTHER TEAM (home or away depending on the GAME) which would have lines of +3.5, +7.5, -2.5 and -6.5.

----------------------------------------------------------

Hopefully that clears some things up.

BUT YES, I clearly made a mistake in the FIRST PART as I multiplied the losses times $120 instead of the $110 we would put on a -110 line to win an even $100.

THANK YOU!!!!   THAT'S WHAT I HAVE BEEN WANTING PEOPLE TO DO!!!!  IF YOU SEE A QUESTIONABLE STAT, PROBABILITY, CONCLUSION, OPINION, ETC....PLEASE QUESTION IT FOR ME!!!!

Like I've said before, this is a work in progress and Mona Lisa wasn't quite herself until she had lips painted on!

2nd part is incorrect.

Think of it this way.

* I flip a coins - head I take home team, tails I take away team.  So I am a 50-50 bettor.

* In 705 games, I am going to win 1/2 and lose 1/2 - so I will lose 7,050 in those games (b/c line is 120 on my losses).

* Now, in the other 58 games, I am going to either TIE or WIN.  So, 29 times I tie and 29 times I win - so I win 2,900.

* So I lose 4,050 in 2nd case vs losing 3,680

- so BUYING points is BAD.

* Your assumption of 50-50% bettor is for all the non games where 1/2 point is diff - in those cases even a 50-50 bettor becomes a 75% bettor.

* You DO NOT lose 940 buying points, you lose 4,050.

* AGREE?

Thank you  

I will give you a hint bud you don't have to come into this thread ever. Texas very usefull stuff for those who take the time to understand.

Some lines are right on so the odd time it might be worth it but in the long run it is better to sell half/full pts to get plus money. Then if you are at 50% you are up

I know you don't let the clowns get to you just do what you do.

* Now, in the other 58 games, I am going to either TIE or WIN.  So, 29 times I tie and 29 times I win - so I win 2,900.

I'm not following you:

*Why are we adding home and away to a sample of 763 BETS (NOT GAMES)?  They are predetermined when I found the BETS where we could have bought 1/2 point ONTO or OFF of 3 or 7.  I don't understand the home and away thing. I brought up a 50/50 bettor AS IN he WINS 50 AND LOSES 50 games on average, not picks home or away in 763 situations where there isn't even a home AND away team for those 763 scenarios.  It was EITHER a home or away team, there WAS NO OPPOSING SIDE TO THE 763.

*Where are you getting 705 from?  You can't subtract the games that PUSHED AND the games that would have NORMALLY LOST by 1/2 point on the original spreads.

There were 763 total bets, minus the 27 original pushes would be 736 just like in scenario 1 with the straight -110 bettor. Then out of those 736, half would NORMALLY lose and half would win.

368 would've won before the 1/2 point
368 would've lost before the 1/2 point

The 1/2 point would have changed he ORIGINAL PUSHES ON THE ORIGINAL SPREADS TO A WIN, AS WHY I ADDED THE 27 ORIGINAL PUSHES TO THE WIN NUMBER OF 368 TO GET 395 WINS X $100 TO GET $39,500.

The 1/2 point would have affected 31 games that LOST BY 1/2 POINT, making them PUSHES, so we have to subtract the 31 from the 368 losses to get 337 total losses and then multiplied by $120 we bet on them to get $40,440. The 31 were pushes, so they didn't win or lose, but rather get OMITTED as nothing was lost or won.

*I think where you are going wrong is you are subtracting the games that could be affected (58) BEFORE you should have. A 50/50 bettor would have won 368 bets, lost 368 bets and pushed on the other 27 BEFORE HE BOUGHT THE 1/2 POINT....so you have to work from there. NOW add the 1/2 point to the equation to make the ORIGINAL PUSHES TO WINS and THE GAMES THAT WOULD HAVE ORIGINALLY LOST BY 1/2 POINT INTO PUSHES.

IMO I think you are doing your math at the wrong times.

*Agree? or understand where I am coming from?

*DOES ANYBODY ELSE FOLLOW WHAT I OR KVS23 ARE TRYING TO SAY???

Understand that sometimes people can ADD EMOTIONS to what people type.  I've mistook many texts from friends as being negative in nature, but really they were just saying something without being mad or cocky or angry.

What I am trying to say is Everything typed above (maybe with the exception of my RockPlay replies...) is all DISCUSSION and is merely trying to talk things out in a manner that we can all get our opinions, thoughts, stats, analysis, etc....trough to each other WITHOUT THE CHILDISH ROCK-PLAY, BELITTLING, RUDE REMARKS, AND IGNORANCE that can really fill these forums up too much, and actually get pretty tiring to read sometimes when perusing other people's threads.

I DO MAKE AN ATTEMPT TO KEEP MY THREADS GENTLEMAN-LIKE AND WORK WITH DISCUSSIONS RATHER THAN ARGUMENT.

I APPRECIATE EVERYBODY'S THOUGHTS, ANALYSIS, OPINIONS AS MUCH AS MY OWN AND AM NOT AFRAID TO ADMIT WHEN I'M WRONG.  I ENJOY CONSTRUCTIVE CRITICISM AS IT ONLY MAKE YOU A BETTER PERSON IN LIFE.  BUT BELITTLING, ARGUING, RANTING, ETC...IS UNWANTED HERE.

DISCUSS ON AND THANKS IN ADVANCE!

NEW DATA HOT OFF THE PRESS:

I sifted through the 7 years of data again to find out what amount of the 763 games that were ON or 1/2 point OFF of 3 and 7 and broke them up, as some people have said that they ONLY BUY TO 3 and 7 FOR THE PUSH.

763 games that were on or near 3 or 7

421 games were originally ON 3 or 7
Of the 421 ON 3 or 7, 27 were originally pushes.
27 divided by 421 = 6.41%

342 games were originally 1/2 point OFF of 3 or 7
Of the 342 OFF of 3 or 7, 31 originally didn't cover by 1/2 point.
31 divided by 342 = 9.06%

Buying TO 3 or 7 not only proved to have a 2.65% more success rate, BUT let's not forget,..."saving" the amount risked on the games that changed from a loss to a push is HIGHER than the amount WON on pushes to wins.

----------------------------------

Buying OFF 3 and 7 for a Win instead of Push calculations risking $120 on -120 odds:

Out of 100 bets buying OFF 3 or 7 for the win with 6.41% probability is 6.41 (rounded down to 6) extra wins x $100 = $640 "savings"

Out of 100 bets buying ONTO 3 or 7 for the push instead of loss with 9.06% probability is 9.06 (rounded down to 9) extra wins x $120 = $1,080 "savings"

$1,080 > $640
9.06% > 6.41%
Buying TO 3 or 7 > Buying OFF 3 or 7


Conclusion: If you are going to buy around 3 or 7, it look like it was more beneficial to your bankroll buying TO 3 or 7 for the push as opposed to buying OFF 3 or 7 for the win.

Conclusion: If you are going to buy around 3 or 7, it look like it was more beneficial to your bankroll buying TO 3 or 7 for the push as opposed to buying OFF 3 or 7 for the win.


#1. Noticed that when I spit up the Total data into buying ONTO 3 and 7 VS buying OFF 3 and 7, I made a mistake of when I rounded down for a quick calculation, but didn't use the rounded number...not a big difference, but not a fan of having wrong data out there.

I  corrected in red above.

#2.  While the quick comparison of the above quote gave an "idea" of what could be "saved", it's just that; a quick comparison. I don't know what the word is, but it's just a way of "relating the differences in probabilities".

To understand the actual amounts of money that a gambler would incur, a more in-depth calculation would be needed.

I didn't have time until now to express whether or not they individually would have been beneficial or profitable to buy in those cases or to show what kind of actual "savings" each would produce.  Here are the calculations:

---------------------------------------------------------------------------------

421 games were originally ON 3 or 7
Of the 421 ON 3 or 7, 27 were originally pushes.
27 divided by 421 = 6.41%

50\50 gambler NOT BUYING the 1/2 point on situations that were ON 3 or 7 risking $110 on -110 for $100 in winnings and betting 1000 bets (1000 for less rounding and more accurate calculation):
1000 bets x probability of 6.41% where there was an original push ~= 64 pushes
1000 - 64 pushes = 936
936 bets divided by 2 to get 50/50 wins = 468
468 wins @ $100 = $46,800
468 loses @ $110 = $51,480
$51,480 in loses - $46,800 in winnings = $4,680 in losses


50\50 gambler BUYING the 1/2 point on situations that were 1/2 point OFF of 3 or 7 risking $120 on -120 for $100 in winnings and betting 1000 bets:
1000 bets x probability of 6.41% where there was an original push ~= 64 pushes
1000 - 64 pushes = 936
936 bets divided by 2 to get 50/50 wins = 468
468 wins PLUS 64 games that WON INSTEAD OF PUSH = 532 wins
532 wins @ $100 = $53,200
468 loses @ $120 = $56,160
($56,160 in loses) - ($53,200 in winnings) = $2,960 in losses

$2,960 in losses BUYING the 1/2 point point IS BETTER THAN $4,680 in losses NOT buying the 1/2 point

CONCLUSION: Buying the 1/2 point WAS BENEFICIAL TO A BANKROLL

----------------------------------------------------------------------------------------

342 games were originally 1/2 point OFF of 3 or 7
Of the 342 OFF of 3 or 7, 31 originally didn't cover by 1/2 point.
31 divided by 342 = 9.06%

50\50 gambler NOT buying the 1/2 point ONTO 3 or 7 risking $110 on -110 for $100 in winnings per game and betting 1000 bets :


1000 bets with no pushes due to it NOT being a whole number on original spread = 1000 bets that won or lost
1000 bets divided by 2 to get 50/50 wins = 500
500 wins @ $100 = $50,000
500 loses @ $110  = $55,000
($55,000 in losses) - ($50,00 in winnings) = $5000 in losses

50\50 gambler BUYING the 1/2 point ONTO 3 or 7 risking $120 on -120 for $100 in winnings per game and betting 1000 bets :

1000 bets with no pushes due to it NOT being a whole number on original spread = 1000 bets that won or lost
1000 bets divided by 2 to get 50/50 wins = 500
500 wins @ $100 = $50,000
1000 bets x probability of 9.06% where there was a bet that lost by 1/2 point ~= 90 loses that lost by 1/2 point
500 loses - 90 games that ended up being PUSHES instead of LOSSES = 410 losses
410 loses @ $120 = $49,200
($50,000 in winnings) - ($49,200 in loses) = $800 in WINNINGS

$800 in winnings by buying the 1/2 point is better than $5,000 in losses NOT buying the 1/2 point

CONCLUSION: Buying the 1/2 point to get more pushes WAS BENEFICIAL TO A BANKROLL

--------------------------------------------------------------------------

OVERALL CONCLUSION: Buying 1/2 point ONTO the key numbers of 3 or 7 for more PUSHES was MORE BENEFICIAL than buying 1/2 point OFF of the key numbers of 3 or 7 for more WINS.
