Breaking News - 20.08.2025:Tour paused, later more info..at least I can say, GM2500+ based on 2500+ Elo GMs games, at same time means, GM2500 played vs each entry x 600 games,Where the trend ones are played each other x 40 games...so now is more clearWhich perform better in case of much various openings, as we know, HumansOpening game play is totally different...yes, a new method about stressing theTrend Eng openings vs Humans openings and I hope you like my new tour idea..And as usually, Messi is Messi! Yes, the master books are Number One again!!As same words going to masters Hamdullah and OrgZ, both (Queen's GambitAnd Tunafish) can be counted even as old dated, especially Tunafish...but still They performed at one of best ranks! And who said that the old books should Not be in?) once more: The powerful move is not in date/ in size, but in correct line!But I admit that DON series performed not bad too, plus OPTIMUS, Cevdet, Arpia etc.
     The Private Book Champion: Biyuya - My Congratulations to  Angel Morano!      Public Champions: AdrianOliva +Tunafish - Congrats to A. Morano, T. Ramz!
