I don't mind preflop calling a suited ace when we are on the button - while stack-sizes could be deeper for this play, but Ham plays long enough to get away if an ace flops.

I still think you have to bet this flop. If you play a suited ace you are looking for a flush-draw, and if you hit you have to play it aggressively.

More interesting is the bet-size on the flop.

You have at least 9 outs - aces might be outs, but we are not sure about them, so let's make it 10 outs. So we are 38,4% likely to win this hand.

If we bet 2k - as you did - and get reraised all-in we get odds of 1:1,5 if BB shoves and 1:1,35 if it is CO.

With 10 outs we need 1:1,6 to call.

So I think your only mistake was the bet size. Against CO's stack size you have to overbet the pot - I'd make it 4,5k. You still have FE and you get the proper odds to call an AI.

In these situations if you just check behind and another heart hits on the turn you won't get any more chips in the pot most often, so playing suited aces gets -EV if you just play them passively.
