50NL: Good player donks all-in on turn, 3b pot

[AZplaya]

hand 1 looks like a standard cooler, I probably play it the same, maybe shove the turn some % of the time.

I think this is a fold on the turn. I think you narrowed his range pre flop and there are very few hands in that range he would play like this. FWIW I don't think 3 betting pre is mandatory in this spot. By just calling you keep the pot smaller and his range wider.
