Villian had just sat down, and these hands occur within 10 hands of each other (with the villian playing just about every one, I believe)

Same villian, and just before this hand he showed a crazy bluff in a large 3-way pot (with 72o).

Is this okay in both cases? I feel like the shove was an overbet in the second one, and I generally suck at playing PP so any help is appreciated.

FWIW, I'm not that good and am working extremely hard to get better at this game, so any advice you guys can give will help tremendously.

Also, my BR is at $350 and I was wondering when is a good time to move up to $10NL. Advice?

Thanks,

Ill.
