### A Little Fun

Here’s an extenion of an old idea. I came up with it awhile ago. Enjoy!

BTM h#2 Without Queening A Pawn

(= 4+4 )

 (Read Only) pid=18064

Here is the solution: 1. e2. e8=WK! 2. e1=WR! 0-0-0-0-0-0#! (WKe8->e6, WRe1->e7)

P1359646 introduced me to the idea of castling with a newly minted king and rook. The extra conditions, as far as I can tell, are that the new pieces must be opposite the starting sqaures of the rook and king, The new pieces have technically not moved.

I then thought, why not apply Pam-Krabbe castling? With the king promotion, it can be done on the other side of board. Black’s promotion into a White rook was the only way to do it of course. It also further serves to extend the overall joke.

Many thanks for the inspiration Andrew Buchanan!

What's wrong with 1.Kxb7 e8R 2.Ka8 Rxb8?

 (Read Only) pid=18105

And why not 1.Kxb7 e8R 2.Ka8 Rxb8#? - Perhaps because the illegal mate without wK?

Should be an easy fix.

BTM, h#2

(= 5+4 )

 (Read Only) pid=18107

Are You sure?! But Chess is a royalist-patriarchal game and White can't play with a vacant throne. (as already pointed out by NP).

 (Read Only) pid=18108

Yes, I’m sure Zalmen. The entire problem isn’t meant to be orthodox. It’s a neat joke.

 (Read Only) pid=18109

Hmm, but then Black can also promote to wB and White mates with Bg3#.

 (Read Only) pid=18112

Like this, maybe?

(= 3+3 )

 (Read Only) pid=18113

Not yet.
1.e2 e8K 2.e1wQ Qe7#

 (Read Only) pid=18116

Yes, but there is still the restriction «without queening a pawn.» Otherwise, I don’t think you can prevent 1...e8Q 2...Qe7#.

 (Read Only) pid=18120

Geir has found a correct diagram.

And Siegfried, there is the restriction of no pawn queening.

twin (b) Pe3 to e2: 1.e1=wR e8=N+ 2.Kd7 Re7# (not 1...e8=K 2.?? Zz)

Excellent idea, but there is also 1.e1wR e8bN 2.Nd6 Re7#.

 (Read Only) pid=18125

Better than excellent. It should be a way to fix the dual, because Your mate is ideal.

 (Read Only) pid=18126

(= 4+3 )

(b) pe3 to e2

*!?

# (or b before a :: because Knight f8 have no function in a)

(= 4+3 )

(b) pe2 to e3

#

 (Read Only) pid=18128

Yes, you are right. I had forgotten about the restriction.

Great settings you found!
(EDIT: I meant in general, not only directed at Zalmen Kornin)

 (Read Only) pid=18129

Wow, I'm unable see what's so great about wSf8.

 (Read Only) pid=18130

Do You prefer two promotions to Knights of opposite colors in e8!? Well, for me it's ok... The mating frames are different

(= 3+3 )

 (Read Only) pid=18131

Black moves (Kd7 and e1=wR) can be interchanged.
