You said players 7 & 10 were solid players. could player 7 be trying to steal $10 in a late position[what is his history?]. player 10 did not raise on the button[A-K, A-Q MAYBE SUITED to call $12 blind]. does player 7 have a large pair or trying to steal. playing 8-9 suited to call a flop[$39 in pot], may have a chance to steal a decent pot. player 7 will probable come out betting no matter what the flop is. tough call.
