Hero???

Out of position with someone calling is tough. If this were me, I would try to keep some pressure after the third spade hit. He has a good hand because he called preflop, but he does not know that you might have hit your flush. If he had a set or two pair the flush on the board might scare him off. If he's the one with the flush you will see a raise if you lead bet.

I say lead for just under 3/4 the pot. If he riases, your toast. If he folds, you win the pot. If he calls, re-evaluate on the river.

Villain can deffinately have AJ AQ AK 99-QQ. I fire again small. Not sure I like the preflop 3bet we need some reads.

dont 3b him pre but given the flop make it $5 and jam the turn

Ok thanks everyone. I 3bet pre because I figure in a readless situation raising>calling>folding is generally true. When I call I feel like i'm always c-folding most flops and that maybe i could profit from a more aggressive line. But i ended up stacking off against AK here and this doesn't seem to be all that uncommon for me, so i guess i need to use more discretion.

IMO your distance above his range is not large enogh to 3bet pre given your positional disadvantage. i tend to nit it up and fold.
