T7s vs lagtag

[KitCloudkicker]

full 10.

villain in this hand is a regular. plays lagtag/solid and pretty much crushes this game. we've been in a few confrontations today and so far i've had the best of it due to me outflopping him.

anyways some dumb limpers and he limps the button. i complete SB with T7s. BB checks.

flop is 236 two spades. i lead out, the bb calls, a limper calls. he raises. i call, BB calls.

turn red 7. I check, BB checks, he bets, I insta CR, BB +limper fold, he insta says "3 bet" really loudly, I call.

River plan? obv CR a flush riv but what about a 7? what about a blank?
