Qe6+ Kd2 4. Qf7 d3 5. Qg7 Kc1 6. Qe5?? (6. Qa1+ Wins.). Tablebases yet have problems, and Fritz5.32 also has some problems with problems with promotions. Another problem, what Chessbase wants to say with "engine now mates with bishop and knight"? I don't understand. Best regards, Paulo Soares, from Brazil
