Steal Called - now what?

[Rolen]

Nope, but that's what i'm putting him on now.

He doesn't check/call an overpair on the flop
He doesn't call the flop with just overcards
He doesn't check/call the flop with the big stack and an open-ended straight draw
He doesn't check/call the flop with a set (unless he's stupid)
He *does* check/call the flop with some sort of marginal drawing hand.
