It's $23 to call on a $50 pot, so I need to win 31% of the time to justify the call... but on reflection I think I am beaten here at least 70% of the time. I think the raise on the river is OK so long as I fold to the all-in.

Interesting to note though that 3♠ was the only card in the deck that would make my hand and give him a stronger one... how unlucky is that?
