 Hi Les, After 5@a6.......can't 9 still occupy f6.I think you need a few extra elliminations to reach a contradiction.Best Regards, Alfred. 02/Dec/16 9:49 AM |  |

 sotir is right, one must give to Caesar what is Caesar's and to Alfred what is Alfred's...So, congratulations to you too, Alfred. When I reconnected on December 3, my attention was drawn on peterj's message. My laziness then made me read only Eureka paths...Best regards, cenoman. 03/Dec/16 8:56 AM |  |
