Wow those hands are horrible.
A7s... just 
call the 
raise. This 
shove is stupid, if 
villain has a 
flush draw you allow him to 
fold instead of make his hand, if he has a 
set you're spewing your 
stack, and on the few occasions he has a hand he folds, you win peanuts compared to what you risk. Calling is easily +ev, it's a no brainer 
call. When we miss the 
turn, we decide how big he bets and either 
fold or 
call. It's ok to miss draws and 
fold the 
river when you're getting a good price to 
draw.
KJo... It's hard to comment on this without 
villain stats. Can he 
call unsuited 
Ax hands to the 3bet? We're basically looking for him to 
fold out his ace high hands that missed the 
flush, but if he's not an idiot he doesn't have the ace 
flush draw unless he has like AJ-AQ. Giving up after 
flop seems reasonable, though I'd consider folding pre unless I can see that 
villain raises 
button a lot and folds to enough 3bets.
TT... you should probably 
fold to 
flop raise. But the 
turn is like the easiest 
fold in the world. When he shoves, he turns his hand 
face up. If he hasn't got a 7 in his hand, I'
m the Pope.
JJ... easy 
fold pre, unless we have 
notes on 
villain that he 
open shoves 
light. He probably has AK, but it can be 
QQ+, especially if he thinks he's getting a 
loose call from the 
big blind. And believe me, this is a 
loose call.
63s... this is fucking awful. 
Fold or 
raise pre (
raise is ok if 
villain steals a lot bvb, and folds to 3bets, if not it's a clear 
fold). 
Flop is such an easy 
fold, like ridiculously easy. Yes, sometimes an idiot will do this with AK, but it's rare and even when he does have AK, he has 
equity against your hand.
Honestly, I'
m getting the impression that these villains know you make bad calls for your 
stack, and they're taking full advantage. I'd be 
overbet shoving into you for value if I knew you were making these calls. 
Please, learn from your mistakes.
