I was playing a variant chess game called Circe Parrain with my friend Kevin [he loves games with weird rules]. Anyway, he had white and the move:


Mate in 2
Circe Parrain

And wouldn't you know it, he hit me with GP's pattern.

Circe Parrain: After a capture, a piece is immediately reborn on the next move. The rebirth square is on a vector of same distance and direction as the next move. For example, if white plays Rxg2, and black replies ...Bh3-d7, the pawn rebirths on c6, because g2 to c6 is a similar vector as h3 to d7.

This looks brilliant SG

Can it be done on a PGN thingy
(though I'm pretty sure this one checks for illegal moves).

Can you do a move by move fen to make it clear.

I know I'm a pain but you know I cannot solve these barmy chess problems.

(and I'm preparing a post with another RHP window open ATM)

Solution:

Start position



1.Kg1! zugzwang


1...Bxg4


2.Re6[+wRg6], mate

The white rook rebirths on g6, since g4 to g6 is a similar vector as white's move e4 to e6.

Keep forgetting to post this.

Try it out amongst other players.
It's surpising how often less experinced players get it so quickly
and yet stronger players struggle.

Now you have it, like other patterns you have messed about with,
you will take it to your grave.

Is that position actually reachable in a game? Don't see how. It puts the king in mate but how would you force that from some previous position?

You can't. It's illegal.

1. Nc4-d6+ Kf7-f6 reaches the first position. Unlikely, but legal.

Of course black can't mate, no king🙂

Q + R are quite able to slay a lone king 🙂
