Go up one level in this thread


     Here are the two positions:
     1. White: Ka2;Qb1;Na3;Nd8;Bb8;Bf5;Pawns:e2,h2,a4,g5,d6,f6
        Black: Kd5;Nc5;Nd7;Pawn:a7

     White to move and mate in 4 moves. In the manual, Novag
says that Diamond II needs 40 seconds to find Bxa7 and announce
mate in 3 more moves. If Diamond is set on normal playing levels
(I presume on the infinite level), it takes the computer only
11 seconds to find e2-e4 for a "mate in 5" solution.

     2. White: Ka3;Ra8;Ng8;Pawn:h6
        Black: Kh8;Qh3;Be4;Bf6;Na5;Nh5;Pawns:c3,g3,c4,c5,e6,g6,h7

     White to move and mate in 6 moves. Novag claims that Diamond II
needs 46 seconds to find Rb8 and mate in 6 moves. On normal playing
levels, a solution is found in a couple of hours.
     Please let me know what are your results.
