Good idea! > According to rough calculations (excel not having big integers), > all the positions where black occupies 10 or less (regular) points are > already less than 2^64. > True! Do not use Excel because it has limitations like the one you mention, and lot's of others. Use Google Docs Spreadsheet, and you can quite easily extend it with Javascript functions. And of course you can share your spreadsheet with others. I've made the Trice calculation in Google Docs here: https://spreadsheets.google.com/ccc?key=0AiXPuo_wblgydHFVY0stekZkZ1 > This can even be refined, as in the total there are positions where > white occupies more than 11 points (and impossible positions, game > over positions etc). > Yes, I believe this is theoretical possible. Thanks for your suggestions. I then just have to find the perfect hash function. I guess that can be done in couple of hours. I'll just get a cup of coffee first. I'll post a follow up mail when I've found it. :-) -Øystein
