Mate in Two

Oliver and Leo had a go at this one, a favourite of mine:

Over to you!

Some points for starters:

If the Knight and Bishop move, that's checkmate, and in fact, no other mate in two seems possible.

Those are 8 black Pawns about to Queen, however.

So, move the Bishop somewhere, say, 1. Be6, to prevent the black King escaping.

Now, 1...a1Q 2.Na6#

And even 1...c1Q 2.Nc6# and 1...e1Q 2.N any #

But if Black promotes another pawn, it might be mate, but not in two.

So, just pick up the Knight, pretend you've moved it somewhere.

Now, after all but one Black promotion, White mates by parking the Bishop on that file, stopping the Queen block.

That should tell you where to move the Knight...

And of course, 1...Kg8 2.Be6#

Solved!

Chess Quotes

On advanced ideas:
"After giving a student the basic mating patterns and strategies you must begin giving them advanced concepts. At first these ideas will not make sense, many players will have a vague idea of what you are talking about but nothing more. Even a fragmented understanding of these concepts will prove useful though, and eventually they will improve as these lessons are assimilated by repetition and example."
— Jeremy SILMAN, The Amateur's Mind, 1995

"We begin with the hypothesis that any subject can be taught effectively in some intellectually honest form to any child at any stage of development. ... (The "spiral curriculum") ... Is it not possible ... to introduce them to some of the major ... ideas earlier, in a spirit perhaps less exact and more intuitive?"
