Did you analyze Rd5 to find that it is a drawing move? If Rd5 is also winning then this is not a good test position. I did not analyze the position so I do not know. I find that a lot of general principles are wrong in practical games. Here are 2 examples from the last comp tournament. 1)Yace-shredder [D]3r4/6k1/2P3pp/p4pn1/Pp1P4/1P1R4/K1B4P/8 b - - 0 1 White should not lose by the chess principles that I know because rook and bishop is better than rook and knight and white has 2 connected passed pawns but I believe that yace is already lost in this position. 2)Nimzo-gromit [D]8/8/4B2k/2p5/5p2/3b4/5PP1/6K1 w - - 0 1 Nimzo played 103.g3 following the principle of kapablanca that the pawns ssould be in squares of different colour than the bishop White lost after 103...f3 104.Bd5 Be2 105.Kh2 Kg5 106.Kh3 c4 107.g4 Kf4 108.Kh4 Bd3 109.g5 c3 110.Bb3 c2 111.Bxc2 Bxc2 0-1 I prefer 103.f3 Uri
