Well on the flop I made a contibet of course. Turn I checked behind and River? I checked aswell. I don't want a c/r but on the turn he shows weakness and und the river he would have bet (after my check on the turn) if he had a nice hand.
DO you bet 1/2 PS here?

I do it for the given reason, he showed weakness. I had almost the same hand yesterday. Youre controlling the pot on the turn by checking behind, hes checking again on the river, so you can easy make a VB here. When hes c/r you big just lay it down.

Check behind on river is fine, what hands are you going to get value out of? I don't see how 2pair or a set can give you credit for a backdoor flush.

[lexxor]

for them it often looks like hero is bluffing the river. i often get called by a K here. (im playing nl10, but i think theres not a huge difference)

[C4LL4W4Y]

Yeah maybe a K might look him up...but I think it's dependent on how bad villain is.

[Grim Reapa]

Def bet here, he has 99 TT KT KJ KQ 76 87 98 type hand, although Ah is the worst possible river card for you so value bet small - without reads $2.95
