Two halves equal a whole

Piece by piece, the puzzle completes;
The one who is the master,
holds in hand the keys of disaster.
Wait until he opens the lock even faster,
answering life's questions then hits delete.

Ascertain with the point of this game;
Your strategy changes up my tactics,
sometimes causing me to go ballistics.
Refrain from trying to understand the statistics.
Close to reaching the target,
that's my aim.

You are not the one, I know this now;
But you are the one who showed how.

Yet, there will always be a part of that remains,
A part of me.
