I would have check called the river on hand one - and I think with the pot being decent it's definitely worth it. I've won in many situations like that when I was "sure" I was beaten by a flush and it turned out I beat two lower pairs or a failed straight draw.

I think your river bet does no good there because IF he has got any spade he would call or raise your bet regardless and he'd probably never fold to your bet.
