why are you not clicking it back to 1475 on the flop???
as played..... damn, that is a HUGE pot for 1/3. about the biggest I have seen. I mean, 6500 is a bankroll for 1/3.
turn is a must call, he is giving you the odds to boat up.
river... fold. he has repped clubs the entire hand. He has something like K
Q
or K
J
.
So hard to fold when you consider how spewy he has been, but that turn bet is SOOO valuey, if he is trying to bluff you out of the hand, he would have done it on the turn.
