So I was in the 1k gtd deep stack tourney, there are 30 players left and I have 21k. Blinds are 600/1200 it's folded to utg +5 he has 30k. He raises 3200, it's folded to me on the button with 55, I call and the blinds fold. Flop comes K3K rainbow, he does a weak c bet of 2400. I shove for protection and after 5 seconds he calls me with A8, turn is an A, river 4. How does one justify calling with at best a 30% hand?
