$5/10, Villain is a younger guy who is very loose PF (high PFR, high defense against raises in the blind) and very LAGGY post-flop with frequent check-raises which may/may not mean he has it. Ran up his stack but I had recently won a few largish pots from him -- one when he called my value bets OOP with a set (he even identified my hand and then called anyway), another when I somewhat hero called him in KK position when he C/R a 3 handed river on a draw heavy board with a lower pair. He has called big raises OOP PF with hands like J2o and 24s (and won those hands) -- lots of variance but now he's on a downswing, it's now 4 handed and he has about $1000, I have him covered. My image started losing, down a buy-in, but I had won a number of pots against him recently and I think he views me as a solid TAG.
I raise UTG/CO to $30 with QT suited. Button folds, he calls, BB folds, $70 in the pot.
Flop comes T54 rainbow. I c-bet $60 and he calls, put $190
Turn pairs the 5 rainbow. He checks, I bet $120. This is where it gets interesting. He moves to raise (but doesn't verbalize), but fumbles his chips and ends up flailing a random mess in the middle. After dealer counts, turns out he bets $220, which is below a min-raise. I have the right now to either allow him to up to $240 or require him to take back the raise since it's not a legal raise. I elect to make him take it back and call the $120, pot $430.
One question here: given his style, would you have checked back the turn? Even if I'm getting value from worse, I don't really have a hand that can stand much heat and perhaps I'm opening my stack up given his track-record of reraising. At the time I was trying to get value from worse and also balancing the times I'm 2 barrelling -- but perhaps this is one of the times when checking back makes sense with a likely value hand since he's not one that you can bet/fold and be confident you are making the right decision.
The river pairs the 4 for a final board of T5454. He leads out for $300 pretty quickly. Thoughts on what you would do?
