Don't check the turn.
We are well ahead of his cool calling range and this turn does nothing for him ever.

As played it's a call given that we look like we want to give up. He can bet lots of hands that we beat.

LAG V would be 3 betting (TT+, A2s+, KJs+ QJs+, AQo, KQo). He could be flatting almost any two solid cards in position and being LAG. (22-99, A2s-ATs, KTs, Q9s-QTs, J8s+, T8s+, 23s-JTs, 97s+, A2o-AJo, KTo-KJo, Q9o+, J8o+). The flop bet sizing is great and it definitely shrinks his range which is what we want to be doing. Flop range is now (44, A2s-ATs, KTs, Q9s-QTs, J8s+, T8s+, 97s+, 87s, 54s, 43s, ATo-AJo, A4o, KTo-KJo, Q9o+, J8o+). I actually like this check because you gain quite a bit of information from what V does. When he pets almost a pot size bet it sure seems like he is trying to charge you for a flush or straight draw, this may be because he has a set like 44, or a two pair hand or has a weak flush draw or a dummy straight draw. With him being a LAG player and a thinking player I think we call. We could possibly raise a significant amount and turn our hand into a bluff. But as played a call is great. Turn range is now T/SPTK, T/SPGK, sets, two pairs and weak flush draws and straight draws I would say. (44, A9s-ATs, KTs, Q9s, JTs, 97s, 87s-98s, ATo, KTo, Q9o-QJo, JTo). On the river so many draws brick so I think we just have to call and hope for a busted flush or straight draw. If you have results of the hand you should post them in 24 hours.

If we check the turn, we need to put in a healthy raise when he bets. I'd probably make it 200 total (inc the 62).
