Your post isn't worded very clearly, but I assume you want to know what to ask yourself before making a move. My input:
1. What imbalances exist in the position and how can I take advantage of them?
2. Is there a tactic that I can use here? An undefended piece or a forkable configuration?
3. What is my opponent's response to my move?
If you judge these correctly, you should be well on your way to winning
I have some thoughts on this (i.e. Opponents checks, captures, and threats)....Any other nodes of thought on this?? Thanks!
