1/2 - tptk facing turn donk vs. relative unknown

Villain's running 27/19/2.5 over a decent sample, 3bets 9%, c/r's flop 11%. Only history is that earlier at this table I 3bet him, he called ip, I cbet a Qxxrb flop and c/f'ed a blank turn.

wtf is this?

Full Tilt No-Limit Hold'em, $2.00 BB (6 handed) - Full-Tilt Converter Tool from FlopTurnRiver.com

saw flop

SB ($203)
BB ($225)
UTG ($128.75)
Hero (MP) ($200)
CO ($218.25)
Button ($201)

Preflop: Hero is MP with A, K
1 fold, Hero bets $6, 3 folds, BB calls $4

Flop: ($13) 2, 9, K (2 players)
BB checks, Hero bets $10, BB calls $10

Turn: ($33) 9 (2 players)
BB bets $18, Hero...

Usually a nine, weak spades or some random float (QhJh etc). Possibly even KJ/KQ.

Call with the intention of calling river depending on sizing and texture i think. The only likely set he can have now is 22. It really doesn't look like a very strong bet to me considering you bet 10 on the flop.

Ok, I was confused and flatted turn...


Turn: ($33) 9 (2 players)
BB bets $18, Hero calls $18

River: ($69) J (2 players)
BB bets $40, Hero...

If it looks like a 9, smells like a 9, than gosh darn it its a 9.

If opp is bluffing this credibly wow good job by him.

haha if i were villain i might play KQ/KJ this way if i didn't think my opponent was going to raise me with his Kx hands. though i'd probably bet larger, like 24-26.

logic says all worse hands he could have had on the flop got there on the turn and river, but i still wanna call the river bet.
