My question is how do you guys play TPTK from any position, and when do you fold it.

Here’s my example and why I have the question.

Prior hand for informational purposes only: Player 1 takes about 25 % of my stack when he hits a 2-outer on the river. No big deal, I put my money in at the correct time so I don’t believe that I’m on a tilt.

Hand in question. I’m dealt the big slick in the BB. It’s called around to me with 3 callers. I make a 3xBB bet. Only one caller to my raise. The flop comes K52 rainbow. I bet 3xBB, and get reraised by the minimum. He knows I will call the raise, which really worries me. Should I fold here?

The other player knows me pretty well, and that, on occasion, bet after a preflop raise to try to take down the pot at that time. It’s possible that’s he is just keeping me honest, but I doubt it considering he has the shorter stack. I’m familiar with the other player as well and can pretty well narrow down his hand to one of the following: AA, KK, AK, QQ, KQs or maybe even TT. He doesn’t like to play small pocket pairs well enough to call me preflop so I'm not really worried about a lower set. After the turn comes a 9 with no real chance of a straight or a flush, I check to him with the thought of a check raise. Well, he bets about 10xBB, so what do I do here?

Like a idiot, I tell him he has AA, and then put him all-in. I probably should have just folded, but I think I might have been on a little tilt and just didn’t realize it at the time. He calls with his AA and won the hand. In 2 hands he went from short stack to chip leader, and I went from chip leader to short stack.

Please advise.
