Dear Mario,

Thanks for taking the time to test my two HAP problems. In the second problem it seems that changing white's 6th move to AxP should eliminate the solutions ending with NxBf8, thus:

1. P P; 2. P H; 3. P HxA; 4. PxP HxA; 5. PxH=A A; 6. AxP A; 7. AxP AxP; 8. A AxA; 9. AxH

With solution now being
1. h4 e5; 2. h5 Qh4; 3. h6 Qxh1; 4. hxg Qxg1; 5. gxf8=N Nf6; 6. Nxd7 Ne4; 7. Nxe5 Nxd2; 8. Nf3 Nxb1; 9. Nxg1



Be a better friend, newshound, and know-it-all with Yahoo! Mobile. Try it now.
