So his 400 chip bet is basically your entire stack (I think you have 105 chips left if you just call).

The thing is, he has position on you and checked behind on the flop. I feel like if he had any piece of the flop he would have bet it. Thus he either has a small PP and is bluffing the river, or he has a hand like A[img]/images/graemlins/spade.gif[/img] 7[img]/images/graemlins/spade.gif[/img] and is betting for value. The way you played this hand you have to call the river, but it's a very tough decision. I guess this is the sort of "tough decision spot" that Jason was talking about in the KQo thread.
