who understands my code

[syzygy]

copy/paste from somewhere

This is how computer chess works these days.

Don't whine. There are plenty of other things to focus on while implementing a chess program that are far more interesting than the 1000th implementation of what we're discussing here.

At least I would expect some understanding about what you copy/paste.

Then he would not have needed to copy/paste.

Anyway, alpha/beta is only the most fundamental part of any chess engine.
