Welcome on board. :(
I tried this position with Fritz 5.03 (106 MB hash) and with the latest Fritz 5
(32 MB hash) for CB7 (last Tuesday)on a PII/300. They both play immediately Ra3
until ply 12. Then I got:
F5.03 F5-CB7 F5.03 (32 MB)
Ply 12 Rd3 14'' 5'' 13''
Ply 12 Re3 25'' 14'' 27''
Ply 14 Ra3 78'' 59'' 85''
Why such a big difference in favor of the CB7 module?
