Some context. Table has been very loose with most villians having a VPIP of 40-50%+. Open sizes have been anywhere from 35-50 without a straddle. Now off to the hand.
V1: ~1000 (older fairly tight black guy)
V2:665 (middle aged black guy who has shown a propensity to be loose and had tabled a huge bluff like 35 minutes before this and also just attempted to bluff hero about 3 hands before this repping the nut flush when hero held the nut Ace)
Straddle pot and there are 3 limps to hero on the button with Q♥ 5♥ who calls. SB folds. BB (V2) Calls and straddle checks his option.
Flop: K♥ 10♥ 6♦
V1 leads for 50 into 60 pot. Folds to Hero who calls. and V2 calls.
Turn is Q♣
V2 bets 75. Hero calls again.
V1 now ships it for 605.
V2 tank folds. Hero???
Getting ~1.8:1 so I need 35% equity. At the time, these are the value hands I put him on: 66 (figured he'd raise on the flop tho), possibly K10 (again likely raises this), figured he would raise pre with KQ. Aside from AJ off, the other most likely holding is J9. At the same time, figured he could be doing this with any Ax of hearts and possibly some suited heart connectors e.g. 98 (combo draw).
