There's a lot of computations involved. A lot of adding decimals, counting squares, etc. It'll probably take you minutes to evaluate each position over the board if you memorize such an algorithm, and a computer works by evaluating millions of positions per current position.
No one ever does such a thing.
Is there somewhere online where I could study the main heuristics used by Chess computers? Does anyone have experience playing like this? It seems it's the optimal way to develop your pieces as the game begins. Thanks!
