Flop KH J 10H. If villain bets small I'm calling or raising depending on bet size and snapper's response. Checks round to me which seemed slightly odd given the table dynamics and history. Snapper likes to shove on Flop/Turn with marginal/losing and drawing hands.
Usually I bet out here but decided to check as my image is super duper tight and I fold out when ahead and get called/raised when way behind. Also Villian will view my check as a complete miss and bluff turn and/or river but never call a flop bet without a strong hand or draw.
Also this is a pretty coordinated flop which I am a marginally ahead some of the time but could be way behind on turn or river. I also don't have a heart. Although I'm pretty certain that snapper and villian also don't have two hearts as villian would lead with a smallish bet and Snapper would shove/make a large bet.
i think u make a mistake checking back the flop here, to a half decent opponent at these stakes i dont think they will expect u to check back strong or air hands in this spot/flop texture all that often.. bet and give yourself a chance to make more effective bluffs or value bets on the turn/river...
i'd only check back here if one of these opponent's is check raising a rather insane amount of the time

as played call river and win or lose at least u'll get an insight into how villain is thinking...
