1. Folds around to me in the SB, I raise
[9d] to $4 and BB calls.
2. Flop
[Ts][4h], pot $8. I lead $6.50 and BB calls.
3. Turn
, pot $21. I check and BB checks behind.
4. River
, pot $21. I check, SB bets $12, I check raise to $44.
Is this good vs an unknown? Those of you who play at higher stakes, with what frequency do you guys pull bluffs like this?
