2 hands v.s Villian

Hand 1 is fine, readless you can't do anything else here, and even if you suspect he's a maniac based on the very few hands you've seen so far, you're not going to find out without risking your stack, so I think the fold is fine.

Hand 2 is poorly played. Either you are confident in your read he's a maniac and you call him down, or you aren't and you fold. It might work as a thin bluff - he might fold an 8 - if he's a maniac he probably doesn't fold a PP 99+, and he doesn't fold any ace. If he's the kind to get into pissing contests and doesn't want to be seen to fold, you could have just 4bet him pre and hope he shoves, but still, even then 77 is hardly the best hand to be doing it with.

yeah, I hear ya, and he could have very well showed up w/ a weak ace here, I'm definitely removing these poor post flop plays from my game.

This guy was pretty much a maniac. One thing I did see is that as LAGdum as he is . He is folding to flop c-bet almost 70%
