Go up one level in this thread


In a previous publication of (the original) 20 endgame positions,
there was a table showing the moves that some strong programs
made. I took the liberty to add these as 'best moves',
just to see if my engine shared the view of at least one of those
strong programs.
Now that numbers 17 and 18 have been replaced (see below),
could someone please also add some 'best moves' for these two
positions? Just use some very strong chess programs to see
how they move, and let's accept these moves as 'best':

8/1ppr1kp1/p1p4p/8/8/5P2/PPP1RKPP/8 w - - bm f4 Ke3; id "sune-eg1";
8/1pk3pp/p7/3p1p2/3K4/6P1/PP2PP1P/8 b - - bm Kd6; id "sune-eg2";
8/4k3/r4pp1/pR6/P4KP1/5P2/8/8 w - - bm g5 Rd5; id "sune-eg3";

6k1/p2b1ppp/8/8/3N4/1P5P/5PP1/6K1 b - - bm .............; id "sune-eg17";
4b3/pp2kp1p/5bp1/8/8/4P3/PP2NPPP/3N2K1 w - - bm .............; id "sune-eg18";
8/6b1/4k2p/p1p1p1p1/2P1K1P1/PP3N1P/8/8 w - - bm Ne1 Nh2; id "sune-eg19";
2r3k1/4pp1p/3p2p1/p2R4/1r6/1P4P1/P3PP1P/R5K1 b - - bm a4; id "sune-eg20";

Of course, any well-founded suggestions to modify these best moves
are welcome.
