I think that the statistics that null move reduce the % of first high may be because of the fact that null move save searching a lot of bad lines I explained it in http://www.talkchess.com/forums/1/message.html?324656 I think that order of moves is important and I know that I still need to improve it but that kind of statistics is not going to help me. The test if I improve my move ordering is simply by finding if I solve test suites faster. Uri
