2 Hands from first 100NL session

[mittman84]

1)CO is 15-5-1.8 after 928 hands (most mined). No reads other than he obviously seems tight.

Hero ???

Do I want to try to get it all in? What is the best way to do it?


2)This hand SB is a complete maniac, he has c/r me on the flop and lead big on turn with air, and has constantly bet very large with nothing. He almost auto pots when you show any weakness. Co is pretty solid, probably one of you. He is playing 30-20-3 over ~200 hands.

SB checks, Hero ??

Whats my plan with a complete maniac (SB) and a decent CO left to act?

The plays are probably pretty basic, but I made the wrong decision on both while playing so looking for some insight.
