First time playing poker in a while, was playing on the lappy so no stats to report. Treat both villains as an unknowns. Is bet folding the best line here? How big are yous going on the river?

All the money on the river, but bigger on turn for value and to make river sizing more elegant. Anything else is leaving money on the table IMO- Villain is realistically capped at Ax when he takes this line and I don't expect an unknown at 5nl to fold many aces either.

^ Interesting. I would have said to check behind before I read your post. I like your take on this though and I'm sure you're right in that anything else is leaving value on the table. Interesting hand, period.

You absolutely crush his range here which consists almost entirely of single-pair hands.

Bet bigger on turn and bet river.
