First orbit, no stats and I don't know how he got his stack.

Here's my though process at the table: I figure sets, JT, KK/QQ and draws are his most likely hands. There's 12 combinations of KK/QQ that I'm way ahead of, 9 combinations of sets that I'm way behind, and 9 combinations of JT that I'm something like 3:1 or 4:1 against. I figure against those hands that I'm about a coin-flip and that he's calling a push with all of them, but I have to weight KK/QQ a little less since he would likely 3-bet with these hands preflop. However, with consideration for 16 possible combinations of KQ plus the occasional two spades (which are less likely because I hold the A and the T is on the board, though I don't think it matters much here), and I think that this is a clear push since calling and getting it in on the turn doesn't seem to have any added benefit, but it could let draws catch on me.

Thoughts?
