With my 3bet I was trying to isolate against a single villain. Unfortunately, I found myself on Turn with TPGK against a big donk. When I was thinking about the range of the villain that made that donk I was not able to found enough hands I am ahead of and there was another player behind me... So I made the crying fold.
This is the range I was putting him on after his donk:
AKc, AQ, KQ, 33, 44, JJ, maybe even slowplayed QQ, KK
