Pre flop sizing is fine.

The flop is a check and give up though being multiway and a horrible texture which won't give much fold equity.

As played I would bet again on the turn to avoid giving a diamond a free card as we don't have one ourselves.

Flop we should be x-folding OOP 3 way. We have poor equity and have to fold to any raise or x-f once called.

Turn is marginal and I think shoving is most likely the right play against a weaker player given the SPR but I'm not loving life. Think the biggest error of this hand was the flop bet. We don't fold better and worse rarely calls.
