I agree with everything you've said. He played it perfectly to setup Kanter, and take his stack. My point is that this late in the tournament, after having outlasted 6k people, you don't NEED to make this play. You don't NEED to put yourself in a position to get outdrawn. Why even take that chance?
I respect Greg, and I know he got a terrible beat. But, he knows as well as anyone that one pair to the river is NOT a great play for ALL your chips. You absolutely positively DON'T want a pot going to the river at this stage in the tournament. Greg could've taken close to half of Kanter's stack, and STILL be in great position to win the tourney without having to go to a showdown.
