Hero ???


villain: 20/15/inf 3b:40 20 hands. he reps pretty narrow range on river(he could have Q high flush at best except the FH or any J), can i call that?

[Mr. Pi]

I would pretty much call. You underrepresent your hand with your line so I can imagine quite a lot of bluffs in his range. His stats arent nitty at all and If I were him I would put you on something like tens or eights.

[castor11]

bluff or nuts...:) Depends on the dinamyc. I would fold, but I'm a nit:D

[Lev729]

Fold.
I think this line is a "how to maximize our value with nuts after villain ch back the flop". :)
