I lose time bank a fold...,
even he limps it is vs reg without special reads,
I think he will not goes all in with weaker flush there any time
it seems like clear call, but my question is: are poeple able to bluff with nuts blocker there ever at low stakes games vs my line x/r and overbet river? I doubt it enough ..., what do you mean?
Thank you :)
