You are correct that pushing a 55% or any
edge is +EV but I disagree that that means it's ALWAYS the best decision to
push it. Chip Reese explained this concept way
back in the original
Super System book by
Doyle Brunson. He said he kept pushing
marginal edges against a
donkey one night in Vegas and ended up losing his money for the night because the
edge didn't work his way while other players ended up busting the
donkey. He knew he could have outplayed him in much better spots but got over anxious trying to
push small edges that went against him. He learned from that situation to be selective about how you attack a
fish and not just jump on the first
marginal opportunity that comes along.
Say, for example, you're against a
loose,
maniac who will
stack off with just about anything, and he keeps pushing
all-in pre-
flop and you find yourself with pocket deuces. Your only options are to
call your
stack or
fold. You know he has any
random two cards and you're the last to
act and everyone has folded. If you
call, you're probably a little more than 50% which IS a favorite and WOULD be pushing your
edge. But, would you
call?
In a tournament with escalating blinds, you'll probably have to
call with Jack high in many situations. But, in a cash game, you decide when you want to take advantage of what situation. You can
call off your pocket deuces now or wait till you get pocket Queens and now you're an 80% or better favorite.
If you constantly find yourself brpushing
marginal edges over big ones, you'll be playing a lot of eak-even poker.
