My opinion -- I am not sold on calling the CO jam understanding his stats are definately on the fishy side...I understand we are mainly focused on the CO due to his stack size.
Agreed he is playing a bit manic but he is calling a jam worth half his stack, I feel he'd be a little tigher here this early with no antes yet.
My question to determine this call/fold is has he made other spewy type of plays in the 66 hands? Called all-ins lite? if so yes, definately call...
If I haven't seen him call too lite, then I'd fold here... My calling range here would be QQ+ & AK
nitty vs this maniac.
