This is one of the stickiest games I've played in. There is essentially no preflop fold equity. On at least two occasions, I've seen a raise of $50 against EP limpers get called in 3 spots.

V1 is loose middle aged white guy, playing 70/20. Due to some stationy behavior, his stack is down to $800 from $1600 a few hours before. Not sure that he understands relative hand strength ... the following hand is relevant: Villain 3bets from the BB to 50, Hero calls on Button with 7Tcc. Flop: 689r. Villain leads for $50, Hero calls. Turn: J. Villain leads for $100, Hero calls. River: x. Villain leads for $100, Hero raises to $300, Villain calls. Villain proudly tables KK and receives the bad news. Another relevant hand from several months back: (Effective stacks $500.) Villain opens to $15 with ATcc, 1 LP caller, Hero raises to $100 from the BB with AA, Villain calls (!!!), LP folds. Villain calls a $100 flop bet on a two club board, and turns the flush to double up.

V2 is another huge calling station. His stack is probably close to $400. All that you need to know for this hand is that his button steal percentage against limpers is probably close to 50%. On one occasion he raised the button to $30 with 65o.

Hero is the big stack at the table at $2300, winning image. In the past 3 or so hours, I've shown down several big hands to scoop >$600 pots, mainly from V1,V2 and one other loose player at the table.

OTTH:

V1 limps from EP, 2 callers, V2 in the BTN makes it $25 . Hero calls in SB with Jd Kc. V1 calls, one other limper calls. Pot = $106.

Flop: 6c 10c Ks

Checks around to V2, who checks.

Turn: Jd

Hero leads for $50. V1 calls, everyone else folds. Pot = $206.

River: 2h

Hero bets $100. V1 raises to $300. Pot = $606, $200 to call.

I haven't seen V1 raise without the goods, however, I'm not sure that he doesn't believe JT or KT is the best hand in this spot. Comments on all streets appreciated.

Given opponent descript, I'd call, If he limped pre with AQ, nh. Probably betting flop with 66.

Pre - given BTN raising 50% of his range, I'd 3b.

Your line in the T7 hand was terrible given what kind of player V was. Raise flop or turn and play for stacks.

Pre is a bit ehhhh even given V2's btn raise% but meh, it's probably OK I guess. I'd bet a bit more on both turn and river. Snap calling the raise. No idea what V1 has but no chance I'm folding top two on this board to one aggressive action.

HH is relevant with the over-valuing of hands.
I've seen fish at my game do this, get called, show KQ, and win (lol). People overvalue hands all the time and if this is a player you've seen do this then its a snap call.
If he shows 66 or AQ this time then that sucks but whatever.
