Final award 09/2020
Judge Marcos Roland
[MD 1556]
(Der Preisbericht erschien auf der Website von Abdelaziz Onkoud Ende August 2020.)
Tries:
1. e5 Rb1?
2. e4 Rb5
3.axb5 is surprisingly too slow!

1. e5 Ra3? fails because of the white king standing around in the way.
1. e5 Rd1? also fails because of the white king standing around in the way.
Mirko Degenkolbe: Dies ist das zuglängste korrekte orthodoxe Hilfsmatt, in dem Weiß im ersten Zuge die Rochade ausführt. (2020-10-03)
