Very passive 1/3 game at an Indian casino in California. Table is mostly full of older (50+), recreational players. There are almost no preflop raises, and it's the kind of game where you can limp in to make a strong hand and get paid off by top pair. Been at the table for maybe an hour and haven't seen much action or very large pots so far.
Hero limps behind in MP2 with Q♥ T♥. Six players see the flop.
Flop ($13): K♥ J♥ 5♥
Checks to UTG+1 who leads out for $10. V1 in MP1 raises very quickly to $30. Hero calls (??). Folds around to V2 in the small blind who now check raises all in for $200 total. UTG+1 folds. V1 immediately calls all in for a bit less (maybe $190). Action is on hero facing a $170 call into $443 pot.
Random bit of information: V1 is in seat 5, and Hero is in seat 6. After calling all in, V1 holds his cards up high to look at them, before Hero has acted yet. A card that looks like either 6♥ or 8♥ is showing (it was impossible not to see this).
I was really torn about what to do here. These were all level 0 players, so nobody is making a play with just the naked A♥. It's possible A♥ Qx (yes, many players here would limp that). Both players have some sort of made hands, one definitely has a flush. Is this a clear call or a clear fold? I don't know what to make of the action and flopping the second nuts here. What range would you put V2 on?
