It is strange, on both my comps I get identical move
12....b5. What seems odd is also if Tony actually played the
game and you also get 12.....Kd8 that's two separate computers
that have some type of bug. Till that move the rest seems fine
it's F5.32 general.ctg book moves till crafty takes Fritz out of
book with 10. Nb3.

Thanks.
