strange one this. Was the plan to 3 bet and fold to a shove? Or was it "I have TT so I"ll 3 bet - **** he"s shoved, better fold then?". Can"t believe the latter hence the "strange one"
In the absense of UTG stats (and yours) and pre antes, I don"t think folding pre is too bad here, but once you 3 bet you have to call this off. You can"t narrow villains range that much, purely on a 20BB 4 bet shove.
Have you seen any hands he played to lose his chips with that convinced you to take this line?
I assume you are raising for value, so getting shipped on by the villain has to be part of the plan, so you have to call.
