NL 100, AK

I checked the turn behind because I was afraid of the flush and I wanted to keep the pot small because of the dangerous board. Bet the turn instead? Opp was loose semi-passive.

this is probably the worst board ever. i don't even know if i call the river, and i'm not betting the turn.

On the river he bets half the pot, looking like he really wants a call on a super dangerous board. I would fold here.
