Not a secret that we call for set main mostly by our postflop odds
But there are some factors that can decrease our postflop EV

1) We cant win enough chips(opponent has not enough strong hands or plays fit-or-fold on flops)  to show profit vs some player postflop

2) in 12% spots we will be versus better set

3) Player is not a full stack(some authors give pot odds 1:20 for begginers to call for set)
and

4) We can face sqz preflop after calling for set maining


So my question is ( especially for calling in MP and CO) what totally %
chance of sqzing should be to give us option 3 bet or fold with low
and middle pockets and also it influence our play with QQ+ AK+ as
slowplay
