An unbelievable key
(= 8+9 )
Dr. Hans Lepuschütz
Wiener Schachzeitung 1956, 2nd prize
Mate in 4
Solution: (mark text to read)
1.Se6+!! dxe6+ 2.Kxg6 zugzwang
2...Qxd6/2...Sc6/2...Sd7 3.Be3+ Ke5 4.f4/Sxc4/Sf7 mate
How is anyone supposed to see this?
And, more important: Do you know other problems with such a crazy key? The famous Schneider #5 (1.Ka8!!) comes to mind, too. The Steinitz Gambit might be too famous. :-) But hey, I don't only call for moremovers, although I do call for orthodox problems or studies.

The eightmover 1.O-O-O! (The play *after* that
is even more unbelievable. This should already
suffice to remember the problem.)

The eightmover 1.O-O-O!
Unfortunately, cooked (1. Kd2 also mates in 8).

I assume Hauke is talking about the 1970 Savchenko problem. It's marked C+ in Winchloe.

Hm, I was thinking about the famous Shinkman’s one from 1887, which also fits the description.

Yes, I thought Shinkman's was a #7, but it's an #8 too.

The Shinkman key isn't unbelievable. Was I so
I talk about the last (?) problem in the Murkisch
book. (OK, if you now keep nagging that he probably
did more than one, I never talk to you again :P)

Hauke, could you please post the Murkisch problem? It isn't in WinChloe.

Not a problem by Murkisch, but a problem in a book by Murkisch.
1st prize, Shakhmatnaya Moskva 1970
(= 13+12 )
Black threatens to break the mating net with gxh5, so white has to be quick.
1. Rd1? Sd2! and next move h1=Q or gxh5.
1. OOO! ab2+ 2. Kc2! b1=Q+ 3. Kc3! Qb2+ 4. Kd3! Qe2+ 5. Ke2 f3+ 6. Ke1 [Now the position is almost identical to the position after 1. Rd1?] Sd2 7. Sd7+ Ke4 8. Bc2# [But the difference is that f3 is now blocked]

There was a similar thread on MatPlus called 'The Wagner move' : http://matplus.net/pub/start.php?px=1267409470&app=forum&act=posts&fid=prom&tid=345&pid=2293#n2293

(Co-)Incidentally the Kraemer problem was shown by me on Friday in chess club. They had fun solving it.
