For the first hand, I don't like your raise on the river. That Ace did not improve your hand (unless you put your opponent on something like 76, but I doubt you did that). I understand that this guy was a lunatic, but still...
For the second hand, capping wiht KQo from MP at a full table? I don't think that's a good idea. Oh, and I don't like your river cap either.
Now that that's out of the way.... um............ I dunno......... Speed?
