With all due respect, these hands were HORRIBLY played.
Hand 1: even if the other guy has a pair of fours and nothing but that, he's still a favorite here. What are you doing calling someone's all in?

Hand 2: Despite the fact that you won, there is NO WAY you should have called that river bet. The only thing you beat here is a bluff, a pair of sixes, and a pair of fours. Any queen with a kicker better than a 6 (which is much more than likely) and any 10 beats you, much less an overpair bigger than queens.

Nice wins, but I've got to say, badly played.
