5/10 Stars. Trying to bluff a TPTK

[Mad Genius1]

Preflop call is marginal I know but I was about to end my session and I wanted to play a hand before I did (bad reason, I know). I'm interesting in hearing thoughts about my flop turn and particularly river play. I put him squarely on AK after the flop with an outside chance of AA, am I wrong to think I can bluff him off that hand? FWIW, I wasn't doing anything out of line before this and neither did my opponent.

Seems like he would reraise all in after your reraise on flop if he had AK because the only hands he could even think of bein beaten by are 55 and 77.

Bluffing TPTK is a losing proposition (just like bluffing AA overpair). Don't plan on making your bread and butter trying to get TPTK to fold. All they need is 1 excuse to call you (he must've been on the flush draw here, and it missed, or he must be overplaying his KQ here).

If the river bet is successful, he probably had like A[img]/images/graemlins/club.gif[/img]Q[img]/images/graemlins/club.gif[/img]
