opposite stance tactic

[shs101]

Stepping on the their lead foot.....this is something Ive really been trying to figure out if it really is successful and worth doing or no.
Whether fighting a sp or are a sp does anyone try this? or even better does anyone have a footage of a fighter successfully doing this in a fight to land a punch or something effective off this?

2 examples are one a lot of people know is jmm vs pac 4 there's a famous pic floating around of the knock out and it has jmm foot on top of pacs foot as he threw his big right hand. Now a lot of times this also happens by mistake, I do not know if he intentionally ment to do it or not so its hard to discuss if actually used it as a tactic.

But one bit of footage I have is ponce de leon trying it on broner...but nothing successful came out of it.

The question is, what do yous think of this? what is a good go to if I actually try this? What is something I should look out for if I do this?

look out to be knock the **** out. instead of training you ask this question. expect tons of answers but from the so called fans. this kind of stuff comes with experience and years of training.
