perhaps a value push?

50 bodog fullring

EP raises 3 blinds, i call in MP with 22.

flop is AQ6, EP checks, i bet 3/4 pot, EP calls.

turn is 8, check check.

river is 2, no flush, EP bets about 1/3-1/4 of pot (i read as a value bet, probably a pair, possibly top), pot is 13$ and we have 40$ stacks, how much do i raise?

P.S. this may be kind've a silly question, but im asking because i have very little experience with massively overbetting for value.

You really think he has an ace and checked it twice? I'd put him on KQ/KK/JJ maybe. I doubt you're getting much more value out him... I'd make a modest raise, to $10-15. I don't think this guy is calling an overbet.

his bet size on the river screams value. i've seen weak players play an ace like this more than a slowplay.

fwiw, he'll cold call a 4 blind raise preflop then call down his entire stack with KT on something like K6592 against my AK. im just wondering how big of bets guys like this will call on the river with a nice looking pair.
