Looks like Galfond's question is more split than Adam and Terrence would have thought, as they seemed to think it was a pretty obvious choice. To refresh, here is that Twitter convo:
Steve O'Dwyer (with others agreeing) said no one cold called. Jay Farber further clarified that a cold call can only follow a 3-bet, 4-bet, etc. But the general definition of a cold call, as we all know, is a call after a bet AND a raise. So if the blind is the bet and a raise is, well, the raise, wouldn't any call be considered a cold call?
To me, the answer is the CO only. The BTN and BB overcalled. Anyway, you can see why the discussion was so varied.
