What is a "Chase System?"

if this is just some thing u do for fun it works, it will not get u rich, bet 22 to win 20 at the start of the day something small because ur gonna have to double it, make 20 bucks a day with a bank roll of about 650, the idea is based off coin flops not for ML stuff, i guess for baseball you would just have over/under stuff. i use this for other vegas games as well. when u trail other good people on this site ur not gonna go 0-5, in doing so u would be digging ur self a big whole, a lot of people that lose it all do stuff like that but with way to much on the line, be carefull whatever system u use
