Did I outplay myself here chasing a nut flush?

You should isolate much bigger preflop, like 7-8 BB.

On the flop I would bet myself like 2/3 with TPGK and nut flush draw.

As played, i would call the flop and surrender the turn, as we do not have the odds to call our draw and our top pair is almost never good in this spot.

Cheers !

Isolate a bit bigger.
Bet the flop yourself.

As played that flop I would call but OTT we probably don't get the odds. And shoving doesn't make much sense because villain is pretty much committed. His line looks very strong and he has only 35bb left. I don't think he will be folding much so no reason to shove when you can't shove as value only.

Squeezing bigger was obligatory

First : not sure if auto-topoff is possible on Global Poker, but if so, play with a full 100BB stack.

As many have said: Isolate a lot bigger, like 5 or 6 BB

As you are the preflop aggressor, and the flop is great for you, I would certainly make a cbet, smtg like 65-80% pot.

You could check the flop, if you make it a check-raise. I still prefer to bet myself thou.

OTT you are not even close of getting the odds needed to draw and your kicker is too low for a call, so I would fold.
