River value bet?

[V4P]

I'm really suprised by the responses. I always thought I was a pretty aggressive value bettor, but this seems like an easy check to me.

Given the action, I highly doubt he has a King, there are like 0 two pair combos, and there really aren't any spadeless 9x hands that should be peeling this flop. I guess A5 is a possibility.

If the river was an A [img]/images/graemlins/spade.gif[/img], I'm definitely value betting, but thats really the only spade I'd be willing to bet
