The way he played, i think he can have a flush (statistically unlikely), a flush draw, a weak Q, or a worst J. He is not paying with a flush draw, so a bet from me its just good against a jack. Then, bet on the river or not?

Pre Flop: (pot: 3,675) Hero has J A

fold, Hero raises to 3,100, fold, MP+1 calls 3,100, fold, fold, fold, fold, fold

Flop: (9,875, 2 players) J Q 2
Hero checks, MP+1 checks

Turn: (9,875, 2 players) 6
Hero bets 4,730, MP+1 calls 4,730

River: (19,335, 2 players) 2
Hero checks, MP+1 checks,

if you're in position id definitely consider value betting. hope he pays you off with like a worst j or a pp with a spade in it. Make it like 40% of pot.

since you're oop though, i think i don't mind checking hoping to induce a bet from villain purely because i don't wanna bet and get raised to like 22k or something.

C/c to give him the chance to bet missed draws

thanks!
