shorthanded, uuhhh i guess I fold?

He's 44/10, no notes. I meant to cbet; I was in a big hand on another table and checked accidentally. Once I realized I threw out a raise hoping to take it down. He calls, ok check/fold mode. Wha? a bet offering 10:1? Can't turn that down. River- i guess I fold? I really wanted to raise his sorry ass for being such a donk but I had no idea what his hand was, and I don't like pulling moves sans hand range.

Edit: and in posting this I forgot about the 4-straight on the turn, but 10:1 is so tempting...

I probably lead the river. That's a great bluffing card for you (not that he's necessarily gonnna fold, but if he would, that's a card he'd do it to).
