$100 NL - AQ versus tough player

[Malachii]

$100 NL 6max

Tough player minraises UTG. I'm not sure what this is, but my notes on him are that he's "Very aggressive postflop, capable of raising weak beats w/ out a hand."

We're playing 5 handed. I consider reraising with AQ on the button, but elect to just call and take a flop. The blinds come along.

Flop is A-T-7 rainbow $8 in pot

Check, check, tough player bets $8. I call. Blinds fold.

$24 in pot

Turn is another A, putting two hearts up there. He deliberates and bets $20. I'm really not sure if I push or just call here. He's probably capable of firing again on a draw here, but I have no evidence to support this. I elect to call.

River is an offsuit J, $62 in pot. He best $50. I think and fold.
