Think the sizing is to large and I'm not sure if I'd like to x/r here in the first place. Even though the board has 3 diamonds we've kind of got it locked up. with top two we block a ton of broadways. I think I'd rather call flop and reevaluate turn, I'd even consider donking turn on some total brick cards as we don't really want to give him any free cards.

The A & Q of diamonds block a load of his big value on this board that he would be opening MP. KT & KJ of diamonds are the only big flushes he can have. We block everything else too (AA & QQ).

I think we can either raise or call.... If we raise, we can get value from a hand with the Kd maybe, even KK with the K of diamonds, maybe Ax too... Although not much else, I'd expect a lot to fold to a raise. If he 3bets our raise, we are pretty much always crushed. If he calls, I would continue betting on any non diamond turn

I would raise to about .70 / .75

It is not bad that is for sure just the sizing is too large. I think 5X is the max we can go here.

I'd call flop, see what the rng brings for the turn and go from there. If it doesn't worsen the board I go for bet turn, bet river about 2/3 each I have this board owned. Villain will let me know very quickly if I'm beat at any stage but most times I think I get a lot of folds no matter.

Unlikely to be a good check/raise here. Hand is unfortunately simply too weak to x/r here in most cases. It's not as if we can profitably stack on monotone board if we face a 3bet either.

To check-raise here we usually need at least middle set + flushes. So x/c flop is good. Probably just play passively and call down unless 4-to-flush completes.
