1. Standard, looks good, but OUCH... no way could you put him on that...
2. Like the flop aggression, but just CALL the min-raise on the river, there are a TON of hands that beat your 1-card straight here... that raise is spew.
3. Well played. Villian is, as you said, an idiot. They play drunk, blind, and high, as well as who knows how many other ways. Don't worry about it, most of the time, you'll be taking their stack. Just be happy he didn't value-bet the river!

Chin-up man, 350 hands is not even worth stressing over. If at 35,000 hands you're still not winning, then maybe we got something to worry bout!
