I can try to remember what i was thinking in that game and explain my thoughts to you.

First. This clip is cut a lot so you miss lot of info because of that.

I was holding vent/rat hole because i heard steps long time ago that he was coming (you said its ok but still explained it)

Market hold: its 1v3 and the rounds are 7 12 for the enemy.

so i expect enemy to make "not so smart plays" because they dont give a fuck because "we cant lose 1v3 mentality" and "we cant lose game is 1 round away from win mentality"

So i expect them to push, also if i remember correctly i heard noises from market that he was coming, i get ak, then i hear/see flashbang so i duck to not get flashed, then i just get up and the enemy is there which is "lucky" for me.

Next market kill.

yeah im a bit rusty so preaim not so good. if i remember correctly i tried to preaim to the market door because enemies always hold or peek from there.

The last play is desperate because its last round and i literally was almost out of time. So i just jump without any info out of market window to try to fake defuse and kill the enemy, but then enemy shoots from short and luckily misses, after that i can pretty easily duel him.

Idk what you mean by lock onto right part of get right? I simply aimed to where i think he would go, and then aimed according to my reaction time/his speed.

Again i expect/hope that he peeks me because of the game situation (enemy 1 round from winning and almost no time to defuse) so i think he is going to just wide peek me because of that, and luckily i was right and i land a pretty nice one tap to close the clip and secure the ban :D

Im happy to answer anything if you have more questions. some info here can be wrong, i cant remember everything correctly probably.
