if you can name just one awesome poker strategy that works for you

Just play your game. Dont "check dark" cuz you saw Hellmuth do it on TV an you wanna act cool. Dont reraise 67suited in into 3 people cuz you heard you gotta be aggressive with suited connectors. Play ABC, tight poker, and dont get impatient and you will beat the low stakes hold em games ($50 and under tourney buy-in and less than $2 blinds cash game) no doubt.

Also, if I was teaching/coaching a new player i would tell them to almost never bluff on the beginning. A main problem I see with new/inexperienced/bad players is they jusy have this mindset that they can never let a pot go, they gotta bluff everything and while "being aggressive" is what you always hear the pros preach, that advice is moreso for a tough, somewhat high stakes game with some quality players, not the absolute donk loose drunkfest that most of these low stakes games are. Bluffing is simply NOT a powerful weapon in these loose games im describing, the players are simply too loose for continued bluffing to be profitable. Im not saying "dont bet unless you have the nuts", you still have to throw your c-bets out there and there will be spots here and there where a little bluff is a nice play but my message is, dont get caught up in any all-in over the top bluffs with total air in these games.

Start playing supertight and loosen up as you get more experienced, instead of the other way most beginners start off which is playing EVERY hand and slowly tightening up as they get more experience. Aggressive is good, loose is not. Most people cant tell the difference between the two but there is a huge one.

Ill post more as i think of stuff, GL
