i agree kitanai -- it looks like either j9 or KJ

-I don't see 88 betting on the flop (most likely take a free card)
-55 VERY unlikely (for obvious reasons)
-AQ, QT (don't see checking behind on turn)

Note: the only other hand I can fathom playing like this is JJ with a sick VB on the river, putting you solely on a 10.
