atempt to a w-shaoe on a 10x10 bord.
Sort:
De W-shape in Dutch on a 10x10 bord.
1.Nh9+ Ki10 2.Bi8 Kh10 3.Bj9 Kg10 het begin van de W-shape.
- Ng7 Kf10 de poging tot ontsnappen begint. 5.Kg6 Ke9 (normaal Kc7) 6.Nf9 Kd9
7.Bf5 deze zet verdedigt normaal a6 en belet de koning te ontsnappen.
7…Kc9 de koning ontsnapt. 8.Kf6 Kb8 9.Ke7 Kb7 10.Kd4 Kb6 11.Bd7! dit houdt de koning toch weer enigszins tegen. Ik ben er ook niet zeker van.
In fact with an adjusted w-shape ( a trible u form ) it will be still a checkmate! Cut the king off from a1 with your bishop and the king and then the w - shape will follow on the a -file!
11.Bd7 Ka5 12.Kc5! dont let him walk to a1! 12...Ka6 13.Nd8 etc and white wins. After 13...Ka5 14.Nb7+ Ka6 15.Kc6 Ka7 16.Kc7 Ka6 17.Bc6 Ka5 18.Bb5 Ka8 19.Nd8 Ka7 20.Nb9+ Ka8 21.Kc8 Ka9 22.Kc9 Ka8 23.Bc6+ Ka9 24.Bb7 Ka10 25.Nd8 Ka9 26.Nc10+ Ka10 27.Bc8#
What variant is this?
Or is this just an enlarged board?
