I realise you mentioned that this was a tough field so 3-bet jamming in this spot is more common among these games, but what percentage of his flat call could have a 2?
It was a great call on the turn when he check shoved. That's a really tough call for me and probably one that I'd end up laying down. Was this player dependent read or do you think that because you ultimately played a pocket pair or complete air type of play, that his shoving range is probably pretty light?
Well to simplify it, he has to have a super tiny amount of hands I'm ahead of on the turn to call anyways. If he has quads or a boat, so be it, but he is calling the flop with a wide range and thus only has to have a few other hands he's shoving with in order for me to call.
I guess a good question to ask yourself in this spot is "What does he get to the turn with?" and then decide what to do from there.
