Go up one level in this thread
I rewrited my move-generator more than 3 times :( and still trying.
I am sooo surprised that I am writing a move generator with similar aspects than
you and these more advanced chess programers without reading any chess engine,
except TSCP.
This is MY work. And if you want to comment or ask something please do it!
Do you think I should restart my gen again?
Thanks

"z" is inside the board */
