Hand 1. I would be tempted to call, but if you really know he never does this with a bluff, he's repping AQ/set and it's a fold. We never beat any of his legitimate river raising hands. This is basically read dependent, and I would have difficulties with making this laydown.
Hand 2. I like raising as a weird semi-bluff, but if he calls I wouldn't know wtf to do even if I hit a spade. So I think bode has a point because we really don't know wtf we're doing in this hand.

and actually see bode for 3/4
