Visserman's cyclic Nightrider Plachutta


Am I stoopid or is the 1684 in Milan's encyclopedia misprinted?

(= 9+12 )


(a3=G, d1,g2,g4=N) 1.Sh4!

Obviously, Nd1-e3 compensates against Rc4 and Ng4-e3 against Nxf5. But what is the
reason White can, after Ng2-e3, not play Sc2+ and Sxf5+ in any order?
(flash of ingenuity - Rb1 is a G?)

After 1...N2e3 you want to checkmate by 3.Rc4+, but 2.Sc2+ closes the rook line.

Ng4 defends c2 if you play Nf5+ first?

1...N2e3 2.Sxf5+ Nxf5 3.Rc4# (not 2.Sc2+? Nxc2 3.Rc4??)

Of course. Confused it with the Keller paradox mechanism.
OTB players shouldn't touch nightriders :-)

Quite opposite. OTB players are welcome to try fairy pieces, many of them, to familiarize and understand - and perhaps to start using them.

Obviously it's too late to do anything about it, but I always thought OTB chess would be more interesting with Nightriders instead of Knights. Even if 1.e4 would not be playable anymore.
