BvB mp flop, 3-bet in SB must be right!?

Played it perfect IMO. There might be situations where I wouldn't get to show-down such as if he doesn't 4-bet flop but then raises turn or river. You could go as far as 3-betting a turn raise against certain opponents, folding if 4-bet but otherwise just check behind river unless improve to 2 pair/trips.

If your read is correct, then the play is correct. Simple.

This is b t w an example of why I, when I am in the BB, usually prefer to bluff raise (if at all) on the turn instead of the flop when I have a good opponent in the BB.

It's ok to reraise and follow through betting. Sometimes he does have a weak king but raise flop is frequently weak and means a small Jx (that he's certainly going to call down) or a gutshot or a purebluff. Call and let him bet could become better than 3betting. But then he has to bluff a lot. Do you think that's the case or didn't he bluff a lot in the recent hands. And in case he's got just a hand like T9, it's ok to just call down and let him make another bluffbet on the River.

Your play is ok with no particular assumptions but with assumptions a calldown may be better. it depends on his blufffrequency and whether he's capable of folding a weaker Jx on the River whereas, if you just call, he's certainly betting Jx on the River. But if you're facing a turnraise on this card, i would fold. I don't think he's raising again with QT and against Kx you don't have any outs as the board is paired.
