I am trying to use Fritz 16 to practice endgames. Unfortunately, Grandmaster (Fritz) is playing very poorly. For example, in the diagrammed position, if I play Black, Fritz gives me a quick threefold repetition after 1 Ke4 Nc6 2 Kf5 Na7. But when I play White, Fritz resigns after 1 Ke4 Nc6 2 Kd5 Na5 3 Ke5 Kg7 4 Bd5 Kg6 5 Kd4 Kf6 6 Kc3 Kf5 7 Bh1 Ke5 8 Bg2.
[title "White to move"] [fen "7k/8/8/2P1n3/8/4KB2/8/8 w - - 0 1"] 1. Ke4 Nc6 2. Kd5 (2. Kf5 Na7) Na5 3. Ke5 Kg7 4. Bd5 Kg6 5. Kd4 Kf6 6. Kc3 Kf5 7. Bh1 Ke5 8. Bg2
Why is Grandmaster (Fritz) playing this ending so poorly? Do I need to change the settings? It doesn't make sense that the engine resigns with Black, but plays a draw by repetition with White.
Any ideas? Are there settings I can change? I have triple checked that I have set the engine to Grandmaster level.
