first hand i agree with sauce, flop min c/r is very weak meaning midpair alot, i dont see him doing this with JJ 10-8 or 77. i think your beating a smaller 9, pushing the turn or calling a river push doesnt really matter to me its all getting all in there anyway in my opinion.

hand 2 call and check it down unless you hit a 7 or 4. the CO wont bet in a dry side and if he does your already waayyy behind
