four hands from last night's 45k

[nath]

results:

Hand 1: Villain showed Jc9c.
Hand 2: I thought forever and called. I couldn't bring myself to shove and I also couldn't convince myself I was definitely beaten. Flop was ATx, villain immediately moved in, and I folded.
Hand 3: I called. Villain showed AA and it held up. Still don't think the call is a bad play-- but lately I've noticed I'm overplaying those midpairs, or at least finding myself in against an overpair more often than I feel is right.
Hand 4: Villain called and showed KK. It's a move I usually make in this spot, but part of me wonders if he knows I'm restealing and was waiting for a legit hand for his next raise.

Thanks for comments.
