That remains to be proved. Better in search? It also remains to be proved. More nodes per second does not mean better in search because other programs may have better search rules. I believe they were inferior in evaluation. The size of the evaluation function is not the important thing. The important things is to get the right numbers in the evaluation function. If you have wrong tables the fact that you have big tables is not going to help you. Uri
