How to use the clock as a piece

I came up with this strategy recently

1. Do as many theory moves as you memorized as quickly as possible

2. Shift gears and go quite slow, thinking of the best responses untill tension is at its highest typically in the first bit of the middlegame

3. When tension is at its highest the opponent typically has a strong threatening move such as hopping a knight to your side of the board. Spend the most time on counteracting this move as it is a crucial point in the

4. Now is when you revaluate the position and time. Typically against players with lots of time left you will have a positional or material advantage so you can continue playing slow and methodical, completely abandoning the idea of winning on time. You NEED to find a mate in this case before running out of time. Sometimes you will face players who are also thinking heavily and have similar time as you. Against these opponents the position is typically equal and You need to gain at least a slight time advantage. The game will probably be decided by timeout or blundering in the endgame due to time pressure. In these games, once a time advantage is gained, avoid trading into an endgame and try to keep the position very complicated so as to give him extra things to think about.

I am only a 1250 elo player so I would love a higher rated players response. There are pros and cons to the strategy but having A plan is better than no plan.
