hand 1 I bet half pot on these flops because I have air most of the time
because this guy is passive you can basically choose how much money you're putting in in this hand
hand 2 you can call or fold, it depends on what your read on his bet sizing is but because of his bet sizing tend to lean towards calling because we only need to win 25% of the time so in absence of reads you should be calling
hand 3 snapcall

I don't know, these hands seem like the hands you lost, not the hands you misplayed
