FD played correctly?

I would just call the flop. SB's range is very wide and include a lot of Ax. I don't think we can acuratly estimate our fold equity, and if we can, I don't think it's too high. I don't like semibluffing here.

On the turn I think betting is not good for the same reasons metioned above. But once villain raises and we are drawing to nut flush in an unpaired board, you have to call.

Flop is a call as it is not ok to stack with just a FD. And folding this equity vs a raise is not ok too.

I would also just call the flop (and then call the turn in case we don't hit a flush). We have a very good draw, but it's not a monster draw.

I agree with the players from above.
Would never play my FD to the max if i did not hit.

We should not be raising flop as if villain shoves flop or turn we have to fold huge amount of equity without being able to realize it.

It would be ok to raise smaller flush draws here as you might not even be happy if you hit it as villain can have higher flush.

As played OTT you have around 18% equity, and you are getting 19% for a call so the call is a loosing call + you will lose rake from the pot so we have to fold turn..

Agreed.

Take a note on guys like this. They are horrible players and can and should be exploited. He decided that you have a FD 99% of the time here, at least enough for him to call flop and check-raise turn with his pair. Obviously, you shouldn't slowplay nuts (two pair or better) vs a guy like this. Also, you don't need to be involved yourself to spot these guys, just watch all showdowns carefully.

I guess it is not correct play. Your opponent is laggy enough. So, let's start from the beginning.
Pre flop: he isolates limper, so he could have a pair, Ax, strong KX and sometime QJ-JTs(6 combos) - you have a blocker. Now, on this flop, he CB,, some of his hand made kind of set(6), but mostly he has AX hand. You are in position, with nice chances to call with Nutflush draw. You have no foldequity vs Ax of laggy opponent. What do you represent? SET? (just 6 combos), if you opponent has AK-AQ - it is never a fold from his side. Anyway, just call flop.
Turn: you got a free card, but you decided to try push him out of the hand, just check behind and get your free outs.
IT IS NL2 - most opponents do not know where the fold button is, especially with possible TPGK or TP+
