well, try to post your hands formatted - its really painful to analyse it raw but lets say I'm having a really nice day today so I've read it through anyway.

Obviously nothing wrong with this hand. If you play NL sometime you might consider this hand an ultimate cooler.

This is not a cooler.

It's a fold preflop imo.  Not a super crazy open, but I'd prefer a fold.  Definitely a fold against the 3bet from the short stack though, no question.

Flop bet is fine, but turn is a fold imo.

If he had AA with diamonds I'd assume he'd c/r this flop, or just cbet it.  The c/c + donk turn line is something players do when they think they're getting tricky, but it's usually just very obvious what they have.

Pf play is definitely questionable but OP noticed that himself so I just skipped that part.

And yes on the second thought I can see a fold here, in the vacuum that might be even better (and not necessarily because AATx is a huge part of his range, how many combos of that are out there ? but whatever he has it still has a decent equity vs our hand, so we rarely crushing anything) but for overall game folding second nuts with blockers to practically a pot size bet is usually not a good idea.
