What is the best strategy for Double or Nothing

[texasman32]

You're paying, generally, a 10-15% rake per game.

For arguments sake, lets say 10%.

If you win 60 of 100 $5+.50 games, you will have won (60*4.50)=270 while losing (40*5.50)=220

$50 profit rather than the $100 profit you assume.

U are right, I forgot about the rake. But as u showed 60% still on the proffit line.
So I guess I need to win more.lol.
