 Nice! Hopefully there will pop up some testers that will find games in 40/40 -
 from these positions - interesting. I'm at work right now - but from memory

 11)  Rd4-d5? is bad - the rook belongs behind the pawn.
 16)..Rd8-b8? is too passive. This is about activity in rook ending.
 18)..Re2xe5! (Fruit!) is an excellent move.

 Furthermore - if 15)  f4-f5 is the old game with Kn+pawns vs Kn+pawns - then
 this position just might be too easy. I will have a look when I have a chess
 board in front of me...
