PLO100 AA63ds turn semibluff?

Villain had been pretty tight pre and post. Flop is sort I would range cbet OOP but IP I think there is no point in betting this. Turn vs half pot semibluff raise felt tempting with nut blockers and nfd. We can put T9 to nasty spot imo. No specific reads about sizing villain used. I guess its ok though as my range after flop check is capped.

The blocker logic makes sense, but I’m not sure the capped flop check helps the turn raise enough against a tight player. Once he bets half-pot, are we actually getting T9 to fold often, or mostly isolating ourselves against made hands and strong draws? I’d want to compare the raise with calling before assuming the nut-diamond equity carries the play.

Problem of calling is that it's also very borderline whatever it's profitable or not. While we have overpair it's showdown value is very limited and even if we are good there is high chance of getting bluffed out on rivers. I would actually be more inclined to just call if we had gutshot to nut straight as well.

Implied value tend to be on low side when flush complete and not sure if we can even value on pairing diamond (straight not calling usually).

T9 in villain shoes is in nasty spot at least without reasonably strong redraw because it's almost dead vs nuts. But that said question is also does opponent bet those or just x-c.

He bets 50% pot on the Turn and we are likely drawing to nut flush, which needs some implied odds then to justify a Turn Call. We could have those implied odds, depending how bad the opponent is known to be.

Then there is another question about the Turn Raise Size, the pot is 31.50€ on Turn and we raise to 52.50€ vs a 10.50€ bet. Does this size look weak or strong on KQ5Jdd Turn after flop went check-check in 3bet pot? I think it looks weak. But I haven't played PLO100 ever. Can we raise/fold if he 3bet jams Turn? We cannot, we have to call then, as he hasnt much behind. I think I would call Turn and fold River unimproved, but of course one can get creative and semibluffraise turn... I think not bad idea and pretty close spot.
