bombardinho, oh boy, now you are confusing me. Maybe i'm totally lost in understanding of the term "ICM", but all of those years it was the same, as "Push or Fold" situation. And why it comes to Push or Fold situation explaining a simple math example:
Let's imagine a situation, where we have 12BB stack. And let's imagine there are no antes yet involved. (Which is sort of unrealistic example, as antes come pretty early at basically pretty every online tournament.) So we're at any position, except Blinds with AKs and about to raise. So what happen with out SPR (Stack to Pot Ratio), when we make a standard x3 raise? Pot is already 1,5BB+3BB(our raise)+3BB(villain call)=7,5BB pot at the flop and we have only 9BB in our stack left. The pot consist already 83% of our stack, which means we're totally pot committed there, we can't just fold a good hand here, because flop doesn't fit us.
Okay, let's take another situation:
We're holding the same hand AKs, but on BU, where we usually raise x2.2BB. Stack is still 12BB. Let's see what happen with SPR now. 1,5BB (Blinds) + 2,2BB (raise) + 2,2BB (call) = 5,9BB in pot on a flop and our stack is 9,8BB left. Pot is 60,2% of our stack still and this is still in HU situation. And this is still a pot commitment for me. As SPR gets too high with basically any raise pre-flop, so why give any chance to your villain to call you off and hit the flop? Better instantly push and play all streets equity + having much better fold equity from players behind you, as it's much harder to call 12BB, as 2,2BB obviously even for a big stack. And also you remove your eventual positional disadvantages on postflop.
That how it is for me.
p.s. Considering that, antes are pretty much often there. Maybe i should re-think my standards about 12BB and increase it a little, something about 13-14BB maybe.. As antes adds 1-1,2BB extra to the pot each hand, which even more increase SPR at the end.
