Poking nose in door -- and a hand i think I blew

[AtticusFinch]

Hi all -- back briefly as I have a bit of a slow period at work going on. So I'm playing a little and posting a little.

Here's a hand from earlier today that I think I played badly.

Early in the FTP $75 mtt, I'm sitting on the CO with about 4k. Button is the chip leader with about 5k. 25/50 blinds, I raise to 175 with qjs. Button calls.

Flop is Q74r. I bet 250. Call.

Turn is a Queen. I bet 450. (Note: I think this was a mistake.) Villain minraises. I consider folding to his probable KQ or AQ, but something smells funny to me, so I call.

River is a 9. I check, and he bets the pot. I call.

Flame away. I'll explain my reasoning after I get some comments.

Edit: no real reads, other than that he's cold-called a couple of raises since I've been at the table, and taken down the pot with no showdown both times.
