Hand 1, good..
Hand 2... I'm not sure what you can put him on that's not QJ [maybe of clubs].

Seems like, given the drawy board and the big pot, he would have raised the flop w/ a set or two-pair, and you're reeking of strength here, so a bluff seems unlikely.

The only hands that seem reasonable are QJ, maybe AT, and maaybe an oddly played set/two pair.

With 3:1 pot odds on the call, it's hard to say, but I'd probably reluctantly call.
