From memory:

Hero is SB with AA at $25 6max. All folds to me, and I want some play, so I just complete.

flop is 6T6. I bet $0.50 (pot) and he raises, I call, thinking he must have the ten. I bet out 2/3 pot on the rag turn, he raises me again, I call. I check the king river, he bets 3/4 the pot, I call.

What does he have, and did I play it totally fishily?
