Hi Joost,

For (1), h#4 would mean white starts and black delivers mate on his first move, since the conventional party (black) doesn't have the first move. So it should be h#3.5.

The "official joke", Art. 15 isn't anything to do with half-duplex. The player to mate remains the same. In the adversarial genres (d#, s#), the opponent gets an extra single move. In h#, Black loses his first move so it's really set play with no actual play.

However, I agree it's best here as h#3.5, for reasons given.

This is not a legal position according to the rules of Chess-960! Pay attention to one important rule in chess-960: The king must be placed on a square between the rooks!

I assume, this isn't a starting position, but an end position of a virtual game ... ("SPG")

But perhaps there is something unclear!?

If the starting position is SQRBBKRS possible is 1.Sh1-g3 Sa8-b6 2.0-0 Qb8-a8 3.Kg1-h1 Rc8-b8 4.Rf1-g1 Sb6-c8 5.Sg3-f1 dia therefore SPG 4,5 (if the white castling is not possible on the first move - in this case there is a dual after 1.0-0).

You solved it correctly. Yes, I didn't see that dual.

This is sound, but no longer than the previous one.

Thanks for all your replies to my original question! Since then, I have composed and published a little Chess960 study.

1.c5 Bxd7 2.0-0-0! Kf8 3.Rxd7! Rxd7 4.c6 Ke7 5.b7 wins.

In standard chess, 2.Rd1 with the same idea would have worked, but here this fails to 2...0-0-0! White has to play 2.0-0-0 so that Black can no longer castle.

I thought in Chess 960 the king still moves two squares only to castle... so for 2. ooo won't the king will move to e1 and the rook to f1.

The castling rules in Chess960 are (have to be) special. Check the following link for details:

I thought we must have already found the longest "APS/ASP/PAS/PSA/SAP/SPA" Chess960 SPG. But apparently not!

Paradoxically for a Chess960 position, this is symmetrical. Normally since we don't know the starting position, we would have different line-ups for White and Black to force a common starting array. But not in this one! :-)
