I don't have a problem with your play here. You flopped top pair. You pushed 400 ( reasonably large bet.)

The problem is when you get called. No one is going to call that bet except another pair of queens, two pair, or a set. This is, of course, assuming your opponent is a rational player. The only thing you can assume, I would think, is another pair of Queens because you didn't get reraised.

As soon as you've determined you're up against Queens, you've got to immediately look at the kicker. You've got a Jack. In my mind, Jacks are the most dangerous cards in Hold'em. They always get my ass burned, but maybe it's just me.

This is the point where it's read-dependent: Is your opponent likely to call the blind with a Q-10 or lower (the only thing you can beat right here?). He's the big stack, so it's POSSIBLE... but you don't get to be the big stack by playing stupid poker. Usually. He's in late position, so he could be on a softer hand than normal, and there was a fair pot preflop. I'd say you're about 50-50. Once you bet the turn (and strongly) and he calls, you've got to put him on AQ or KQ, I think... because he's likely to have thrown away anything weaker than that. I'm checking the river here, and trying to get a cheap showdown, but that's me. No way do I shove all in here, but if I were him and you moved all in on me, I probably question my own single pair here, and lay it down.
