Hand 1

I think you can profitably call and call the river if you make any low (and raise if you make a flush). You can possibly also call profitably if you hit an A, J, 9, or 8. Basically, with the dead 4s it's unlikely he has a straight, and his most likely hand is a pair and a 76 low or two pair. I think calling is pretty marginal, since you will have no idea what you need to catch if you don't buy a spade, so folding is fine also. To the poster Rubix who asks 'what changed between 5th and 6th'...what the hell do you think? We caught a brick and our opponent caught close to perfect.

Hand 2

I think it's a bad fold. You probably are getting scooped, but that doesn't mean folding is correct. I would estimate you winning the high about 1/4 of the time.
