[Retros] Chess960 promotion spot

[per olin]

Dear Andrey,

Thank you for your kind comment! 

Interesting observation about coming to the Chess960IP with black to move. My guess is that a proof game can be made with only either party coming to his initial position after a uneven number of moves. The other party has to motivate the unique sequence of the moves by both parties.

A short one: Chess960IP NNRKBQRB and 1.g4 Nb6 2.Bc6 Nxc6 3.Rg3 Ra8 4.Rb3 Rb8 5.f3 Na8 6.Rb6 Rc8 7.b3 Nb8 C+ Popeye.

Retrocorner colleagues are invited to try to make a Chess960 proof game, where as many black pieces as possible take part in losing the tempo!  

Best wishes

Per
