sess1
raise /call flop. you will see A4,44,K4 but a lot of Ax and FD's also at this stage so is a +EV vs a short. if he is full stack and no reads, fold flop vs a 3bet.

sess2
line OK

sess3
H1- put him AI on turn
H2- b/f turn
fold vs a big bet if he donks turn again
river call is close my guess

AsKc hand
b/f turn
fold river to shove ... we are in a loose/tie situation after his line w/o any other reads

AA/QQ
line ok

KJ
fold turn after his 2nd barrel
b/f if he checks, if he c/c turn, then check back if he checks river, decide on his bet if he bets river
