hand one is fine, now fold.

hand two: dont use the bet pot button too often. Id bet 1 - 1.2 on dry flops like this. If I feel like continuing (sp?) on this turn Id b/f 2.7 - 3 into what would be ~4. Tbh I can´t give any advice on best turn play, Im almost indifferent between all three options and would act based on reads and timing. Vs a total unknown Id say c/f > b/f > c/c

hand three: AJo vs a tight raiser OOP is guaranteed to get you in trouble and now you know why. You have to fold the flop.
