1.Qe3/Qa3? K:b5/K:d5!
1.Qh6!

Or not?

(= 6+1 )

Evgeni Bogdanov
Molod Ukraini 1971
Mate in 2

1.Qa6! Kxe5/Kxg5/Kxf3 2.Qd6/Qh6/Qf1 mate

He could've chosen a pawn, too, but maybe he wanted to give up a battery in the key - who knows...


So two wrong things:
First, the king should be placed somewhere else.
Second, it is anticipated.



PS: You won't believe it!

(= 6+1 )

Levi I
The Times 1900 (!)
Mate in 2

By now you know the solution and still don't know why a bishop was chosen...

What's more, it seems to me there's no last move for Black, therefore Black is to move, but after 1..;Kxd5 there's no mate in two.

Well, I had Jans idea in my mind, but the anticipation (without the retro-error) is of course another interesting fact.

Now that you mention it, it's interesting. All three have no last move. Here are two possibilities - is it possible to keep miniature form?

I find no anticipation of this (only with up to seven pieces, as you know).
