Similar concept to the WA/WB thread, but it does have some differences. This time we also have to include marginally ahead as well.
A big raise back will simply induce weaker hands to fold, including some of the time the flush draw, which we dont want, we want him to pay for his draw. Ok someone mentioned above that he doing that anyway, hes not, we are giving a free card by calling.
I think this is very marginal, we dont want to play a big pot with top pair 2nd kicker even on a 6 handed table.
I like the raise/fold to a push option. Personally if i was the sb and flopped like this with A-x suited, then this is the way i would play it. Calling, and seeing how the hand progresses excercies some degree of caution and pot control, but again we are giving that flush draw a free draw, Calling gives K-x a chance to hit 2 pair, give A-x a chance of spiking an ace, calling here the more i think about it the worse it is.
We gain no information, calling a $25 flop bet, will no doubt lead in a lot of cases to a much bigger turn bet which we have to fold to. BUT here is where it gets interesting. Calling a $25 flop bet lets us see a turn card, and likely a river card in position for the same price as a decent flop re-raise. We have position in the hand, we look very very strong flat calling a flop and turn bet for the same price as our flop raise. And its likely if he misses his draws or feel his hand is inferior we can expect to see a check on the river.
Marginal, I think id still go the aggressive route though.
