I put him on TT+, AK, maybe AQ. haven't seen him 3-bet before. I just called PF in Position which I think is fine if you only do it sometimes. The Flop looked like it was a great opportunity to slowplay, since he would probably call a bet on a later street with most pairs that he'd probably fold to a flop-raise. Turn was a pretty good card since he might have AK and just hit TPTK. I didn't want to bet though becaause he coul have KK/QQ and I'm not sure if I could fold my AA to a push here so I thought it would be better to call/bet on the river. The 8 didn't change too much so I just called.

This certainliy isn't standard, opinions? Did I miss or gain value by taking this line? Thank you [img]/images/graemlins/smile.gif[/img]
