Sucks but I think its a fold! Can't see him doing that with anything other than a flush.

what about stack in off on flop? we run into flush too much?

I'd personally be stacking it on the flop we top set, if behind we have re-draws and they can have worse sets/ pair+ NFDs.

I am for sure stacking off on this flop. We still have decent equity vs flushes, occasionally there are some dream scenarios where we set over set someone in which case we want to get the money in as early as possible to prevent an extra diamond rolling off that kills our action, and there are a decent number of pair+flush draws that can continue in the hand when we are in the lead so reraising flop seems best IMO.

As played the turn is a fold I feel, we're super sad about it obviously as folding sets is never fun but we're going to be behind far too often.

Just ship it on the flop. He's folding a lot, but who cares? We're OOP and need to get the money in; really hard to do that if we call because if he doesn't hit a diamond ott he'll check back a lot when we check. Also, give him a chance to stick it in with a bare Kd - at 2nl in my experience, that'll happen more often than you'd think.

I think your mistake here was to be a bit too afraid of the board. Yeah, he'll have some flushes, but against his whole range our hand is still a monster and our objective should be to get the money in ASAP.

Against an unknown you can stack this on the flop without much worry. With bottom set calling becomes more normal, but with only made flushes beating us and six combos of worse sets plus AJ possibly playing this way just go for it.

As played it's sick but I'm folding the turn.
