Hello...

as I said earlier, I did not mean to imply _you_ had done something wrong
or dishonest.  I simply said that there was something wrong in the setup.  And
that it was a problem that I eliminated earlier this year when I chose to make
the anti-trojan-horse code automatic...

So while I can't say much about other engines, tossing a piece on the g file
to open the h-file simply will not work against Crafty...  It has been tried
by the best "trojan players" on the planet with zero success...
