I'm playing at a Pokerstars Live table and had squeezed in the SB previously with 60bb and ATo, MP had opened to 5bb and the CO flatted the button flatted and I squeezed with ATo to 15bb and the CO 4bet shoved and showed the Td after I folded. In the last session I had some fold equity with my squeezes vs a CO open and a button flat. There seems to be little value in balancing my ranges here when I probably will not play against these players that often.

I'm in the SB with 60BB, it folds to the UTG+5 with about 100BB who opens to 5BB (possible reg) which is not really a lot and the tight button player short flats (passive post flop and likes to bet 4BB on a king high board 2 ways on the flop and turn and river); I squeeze to 15bb with 77, UTG+5 fairly quickly 4bets AI, the button folds. I call and he shows AK. I think I show an EV of +15bb but only because I had 3bet to 15bb with this line but isn't it lower variance and more profitable to just flat preflop and play fit/fold post? I lose 42BB or more so is this line preferable to 3 betting?

against tougher opponents they will raise or 3bet more preflop so your set mining price is much higher maybe 12bb....
