PS $109 Deep Stack: Tough Decision with TPTK

[VK_Rick]

Second hour of the PS deep stack $109. I have been fairly tight, and have not played a hand for a while. My stack is well above average. Villian has been very tight so far (14/2). Call or fold to the all-in reraise on the flop?

fold, theres a player behind and your equity sucks against a range of AT/sets/combo draws/twopairs. i doubt he pushes KT

[VK_Rick]

To the extent it matters, the player behind me was playing, quite literally, any 2 cards. He was like 95/25 over 80 hands, and almost never folded to any bet on the flop, so I think I'm way ahead of his range. The problem, obviously, is the tight player in the SB who raised me all-in. (SB also had to know B was playing any 2)

[VK_Rick]

I'm bumping this one time to see if I can get some other thoughts. I really thought this could be a move by someone who saw my flop bet as a standard continuation bet and was trying to push me off the hand with something like AQ, AJ, 77, 88, 99. On the other hand, I hated to put my tournament life on the line with TPTK.

If you are tight and you think the other players think that - if they are a thinking player, and they call your "tight" preflop raise, I'd be careful with this hand. I really don't think player's bluff that often. I used to think that even bad players bluff often, but I have learned the hard way that they rarely do. I'd probably hit the timer and then fold.
