Exciting future to come...Rybka is the crowned bullet master from rumours I've heard....so relatively better in endings at short time control.... relatively - compared to other engines. But I close my eyes for games in blitz tempo. Two games from the pos 1 in the suite - 40 moves in 5 minutes - were enough. Rook ending and the level of play was...huh... not good... With some more 40-games matches, using the endgame suite, we can study more details - which engine seems to handle the rook ending best? How about the theme "good knight vs bad bishop"? etc. Interesting. To keep in mind - or on paper - the following positions are documented and verfied *won* for white/black - and highly unbalanced - even if some engines don't recognize it... Won positions: N:o 10, 11, 12, 13, 14, 15, 17, 19 Draw position: N:o 16 (black draws with activity only - 1.- Rd2!) Slightly better for black: N:o 20 (the double rook ending by Andersson) Unclear position: N:o 18 (the bishop pair vs pair of knights + an extra pawn) 1-9 are the NunnE positions. /S > > > >On December 31, 2005 at 17:02:13, Jouni Uski wrote: > >>I played 60/5 level match from Sune's positions: >> >>1 Rybka 1.0 Beta 32-bit 0½½0½½½11½½½01100110½0½010½½½½1½½½111½½0 20.5/40 >>2 Fritz 9 1½½1½½½00½½½10011001½1½101½½½½0½½½000½½1 19.5/40 >> >>Hmm?!?!?
