Bizarre 66 Hand with 44422 Board

[Unarmed]

No reads yet. I think its a clear fold on the river. The flop call had me thinking 22, but the river all-in has to mean a big pair right? Anyone call this and/or bet the turn?

HAHAHA, as I'm posting this I click submit and end up clicking raise on my other table as Stars brings the window to the front of my desktop...nice. The hilarious thing is I actually end up with a coinflip! The initial raiser ended up dropping AJ to all the strength I showed. [img]/images/graemlins/grin.gif[/img] (MP2 had 66)
