I'm not saying he's always laying down QQ, although I definitely think it's not a standard call in his spot. I'm saying this:
<font class="small">Code:</font><hr /><pre>84 games 0.005 secs 16,800 games/sec
Board: 9s Jd 5h 6d Td
Dead:
equity win tie pots won pots tied
Hand 0: 50.000% 50.00% 00.00% 42 0.00 { 6c5c }
Hand 1: 50.000% 50.00% 00.00% 42 0.00 { JJ+, 99, 55, AJs, KdQd, KJs, J9s+, 87s, AJo, KJo, J9o+, 87o }</pre><hr />
(J9+ means J9 and JT)
This is being generous in that he always calls AJ KJ (and has that last hand in the first place) and QQ-AA. He might not raise 87o, but he probably doesn't fire three barrels with KJ, maybe AJ, and likely folds a bunch of one pair hands. So I see no value in betting.
EDIT forgot random suited Aces that got there. So def. not a raise IMO.
