$1.5K 6max TP hand

[mlagoo]

Kinda weird hand from the $1.5k 6max today.

So I'm sitting with like 14.5k at 100/200/25. I've been playing very aggressively, probably like 35/30, possibly more. I think that's important.

Button is a middle-aged dude who just moved to the table about an orbit ago. He open-raised his CO his first hand there, hasn't done anything since. He has about 9k.

On to the hand.

Folds to me in the CO, I raise T7o to 600. Button calls, blinds fold.

Flop T42 with two hearts. I have no hearts (whatever I have top pair its the nuts!).

I bet 1k. He makes it 2500. What do you do?
