[Retros] Original in Suomen Tehtäväniekat Nov, 2009

[Olli Heimo]

Once again there was a beautiful proof game by Unto Heinonen in the latest issue of Suomen Tehtäväniekat. I spent almost two hours in solving it. The only help was that assuming the problem is correct, then wQ must have a unique route to get away from herself. 1k3bn1/2rpp1r1/6p1/4B3/2PPPR2/2NKP3/2PPPp2/1N5R 13+9 Proof game in 31.0 moves. Best Olli.
