I caught this hand on the turn, with about 20k already in the pot and Peter Jepsen having checked to opponent Waltersson. He bet 10k, and Jepsen considered for a while before calling.
Board: ....
Now Jepsen checked again, and Waltersson put the rest in - about 17k into a pot of 40k. Now a pause so long I could see their respective beards grow, before Jepsen made the call and was shown by Waltersson, who gladly took the pot as the other hand was mucked before the TV cameras could congregate.
