Free-for-all "Worst Move" task


(= 4+5 )

h#1

Impress me by a) finding out what I wanted to show without needing hints,
b) up the ante "6" (OK, that WAS a hint :-), c) making a #2 of it instead of a
cheap h#1.
NO bonus points for actually solving it :-)

Pin of Re4, unpin of Sg5, line opening to e5, blocking of d5, closing of Bc4 line, unguard of e6.

Some time ago I was plying with similar accumulation of errors, in the s#2 Anticirce form, but the outcomes were quite boring. I can look them up as they are unpublished and deemed unworthy of publication in normal print. But as an illustration of debate...

Does anyone know a good problem with such deliberate accumulation of errors?

(edit: wrong modal verb)

Does this count as "6"?

(= 6+9 )

h#2 (6+9) C+ 1.Kc5+ c4 2.dxc3 ep Re2#

Black's 2nd move: opens d1-d6, opens e3-c5, closes a1-d4, closes b3-f3 and doubly-opens e4-b4. Plus it opens b5-f1.

@ Juraj: 100%! :-O
Yes, PLEASE add your material. It would be interesting whether
s# (which is, well known, more complicated that n#) can add
even more motifs.

@ Dan: As you see from Jurajs post, I tried to max out the
*different* motifs. (Although, obviously, pin/unpin depends
on line opening/closing, so that's rather academically.)

@myself: So I won't get around composing a #2 with 6 motifs
myself :-)

To my surprise I have already published the first example.

Pat a Mat 2006
(= 10+10 )
s#2 Anticirce (10+10)

1.Rb8! zz
1...Rb7 2.Kxb7(Ke1)+ Bxc2(Bc8)#
1...Rc7 2.Kxc7(Ke1)+ Bxc2(Bc8)#
1...Rd7 2.Kxd7(Ke1)+ Bxc2(Bc8)#

Every defence has 5 errors:
- opening Bh4-d8
- opening Rf7-d7
- activating pf3-e2 by unblocking of e7
- hideaway of bRe7 from Bh4 (3.B×e7(Bc1)??)
- allowing capture by wK

...using Anticirce obviously adds the possibility for
some surplus rebirth motifs.
(BTW, the 2# with 6 motifs I did yesterday at midnight.
No big deal for a supergenius like me :-) I add it here
as soon as someone published it.)

I've always thought it paradoxical that although we talk in positive terms about 'strategic richness', composers go out of their way to restrict strategic effects in the name of 'purity'.

Hauke, yes, you are absolutely right about the Anticirce possibilities. Naturally, it was not my aim to show as many errors in the defences as possible, rather I simply wanted to compose an interesting Anticirce s#2 (as it was once the theme of Wola Gulowska). The accumulation of errors was just one idea I briefly touched. No doubt, if we concentrate on the numbers, 5 should be easily surpassable, 6 too, my estimate is that 10 should be possible (in one variation).

Hey, did I let you wait a decade for the announced problem? :-)

1.Bb2! (Sxc7) Sc5 (Moscow, opens e7-c7 and closes a5-d5,
but, unfortunately for Black, opens e8-c6, pin-opens d8-d5,
pin-closes c7-c1, closes g1-b6, blocks c5 and unguards b6) 2.Sb6#
