My first reaction has been to laugh loud at this one, because I thought I had
introduced this knowledge in Chess Tiger already.
Then I tried, and I must admit that Tiger wants to play Rd5 all the time (I
stopped after one minute, really angry).
Grr...
Now I remember, the knowledge I have introduced is about the position of the
black rook in the above diagram. It's something else.
