Hello Robert,

Read this here (translate it) and you can my game understand!

1. Kapitel: Das trojaneropfer (Auszug Text)

"...Hier möchte ich unbedingt erwähnen dass Crafty eine Option mit Trojan Check
besitzt. Schaltet man diese Option ein, so verschmäht Crafty (zurecht) das Opfer
auf g5!..."

Hier ist mein kompletter Artikel zu finden (leider nur in german, sorry):

Eduard
