no read on villain cause first few hands.
is it ok to bet the turn again? i mean so many draws out there. can i rule out a draw when he calls my big turn bet?
and by the river i am totally clueless what to do. i decided to block bet (ok no worse hands will call, but i dont want to get bluffed big).
Or would u check and fold to a big bet?
