Programs that are not clearly stronger than gnuchess may earn more rating from better search techniques or better evaluation and they do not need to care about the optimizations that were discussed. The only optimization that may be important is optimization of the algorithm. I started with a move generator of legal moves. The first version was very slow because I generated attack tables for all the board without memory of the previous tables. Only after working about it and making it about 100 times faster I started to work on a chess program. I believe that it is still possible to improve the speed of my move generator but today I do not care about a possible factor of 2(it is only a guess and I do not know the right factor that can be achieved by assembler tricks+improving the algorithm) and there are more important things to do. I have a lot to improve before thinking of optimization of global variable or assembler. Uri
