Hello David et al,
Thanks for asking.
If Black had really wanted to then he could have chosen either ...Bc8-e6
followed by ...Kd8-c8-b7, or ...Bf8-d6 and then ...Kd8-e7-f8, all dependent on
circumstances.
At the end Black can easily avoid the mate just by playing his King to c6. My
main priority was simplification, or liquidation as some players call it, to
reduce it to an easily won ending. It doesn't matter if it takes another twenty
moves or so to win. You just know that you are winning and the only thing you
have to watch out for is stalemates. Black didn't even give himself that chance.
Regards,
Tyson

Hi, Tyson.
Thanks for showing what happens when the opponent moves way too fast.
I have a couple questions about your idea. First, at what point were
you intending to keep black's king from moving out of the center? It
seems that everything after the knight fork (moves 10 and 11), you
were able to make sure black had no way of moving his K inbehind
cover.
Secondly, Was the rest of your attack after the R sac on move 16 forced?
Thanks in advance for your help.

Hello all,
Again this is a quick post to illustrate a point. But the proof comes in two
bits and the second bit will be posted later. It's also a bit of light
relief after a long day of posting.
Meanwhile your mission, should you choose to accept it, is to play through
this game and notes in less time than Black took to make his moves. Should
you fail ... then that shows you've been listening to me and slowed down,
unlike Black even after he was warned! Don't worry about this e-mail
self-destructing after five seconds. Black has already done that!
Note the very last comment after the mate.
Regards,
Tyson

Black pushes White into simplifying whilst winning a Pawn.}
6. Bxc6+ bxc6
7.dxe5 dxe5?
{Although this gets the Queens off Black's King is left in the middle of the
board. Also White wins another Pawn because he sunsequently forks c6 and
f7.}
8. Qxd8+ Kxd8
9. Nxe5 c5 ??

moved it, but didn't see the
other one.}

12. O-O
{At this point I warned my young opponent to slow down as he was playing way
too quickly. This is the
only time I've ever done this in my career!}

defend this I'd haveplayed 12 f3.}
13. Nxe4 Bxe4
14. Re1
{The pinned Bishop falls. Note that Black can't continue with 14...0-0-0
with the idea 15 Rxe4 Rd1+ and mating because
his King has already moved so castling is not legal.}

White simplify further.}
