if this is all we have on this guy,
easy fold.

He's checking back pretty much anything but b'way, maybe betting sets, if he does bet two pair, it's top two. We lose to anything he bets basically.

I missed that he's nittish, so when he min-raises with 3 b'way's on the board, we can even justify a fold there to a nit. We called hoping to improve anyway.

Pre is fine imo.
Bigger on the flop.
Turn bet is meh, cold go either way.

Call now with 11 clean outs to the effective stones getting just about 4:1 on your money.
You can cooler him when he has a set of 4's for how whole stack easily, and get at leat one healthy $200 bet from him otr when your flush gets there.

Thanks all. Overall, I think I played the hand well except for the turn. I think betting was a mistake. I appreciate the input on each street and bet sizes.
