Final WSOP hand from last night

[gumpzilla]

There is some discussion of this in the WPT forum, but it's the WPT forum, so I thought I'd put it here and see what people think about Black's laydown. From Cardplayer:

Gregory Rice goes all in under the gun, preflop for his last $200,000. Andrew Black reraises to $350,000. Mike Matusow calls. The flop comes 10-9-7 rainbow. Black checks. Matusow comes up firing for $450,000, and Black folds pocket Queens face up. Matusow flips over 10-10 for top set. Rice shows J-5. The turn is a 5, and the river is a Jack, giving him a very cruel two pair on the river. Rice is eliminated, and Matusow is sitting on $5,104,000 in chips.

Black's ending chip count was 2.09 million, meaning he started the hand with 2.44 million if this is correct; Matusow must have had something like 4 million at the beginning of the hand. Blinds were 20k-40k with a 5k ante, from what I can tell.

Thoughts?
