Under Promotion and Good News v Bad News

Wilhelm Steinitz (1836-1900)
and I will be writing more about Steinitz in the coming weeks.

I went to see the Andy Warhol
exhibition currently on display
in Edinburgh.

A complete pile of tosh.

I stayed for 15 minutes.

Ok Chaps here is today's puzzle

I bought a new chessboard on j-bay, not e-bay, j-bay.
'j' stands for junk. I was sent this.

The challenge is to cut the board into two pieces,
not three pieces, two pieces.
Then fit them together to make a perfect chessboard.
Solution is at the bottom.

Last C.C. I asked if anyone had an example of this actually happening.

1. e8=N+ -.

Here are few under promotions with a Knight
but none from the above ending.

First the instructive bit.
In this position with Black to play it is only a draw.

I do not want to fill this site with long analysis. But take it
from it me Black can draw this. See Batsford Chess Endings.

But in this position with Black to play, it's a win for White.

Again I trust the Batsford Chess Endings.
Proving this is a loss takes 20 moves plus many sub-variations.
Most people think it's a simple win if the King is trapped on the
back rank. It's not as clear cut as that. Have fun.

So here are a selection of under promotions from actual games.

But before I show the games I must reflect on a very sad happening.

In the 1980's Duncan Walker and I played a game where I banked
everything on two passed pawns. The both pawns reached the 7th but
I was going to get mated if I promoted to a Queen. So in both cases
I under promoted to a Knight with a check and drew by a perpetual.
I actually had three Knights on the board.

I moved house in 1986 and lost one of my score chess books that had 198
of my games in it. This book contained some fantastic games played
when I was a good player, including the game I just mentioned.
I still pine about it even to this day. (I'm pinning now).

Right. No use crying over spilt beer. Here are the games.

S.Popov - I.Buljovcic, Yugoslavia 1966.
This combination came closest to the main position I asked for.
White to play...

26.Re8+ Rxe8 27.Qxg7+ Kxg7 28.fxe8N+ 1-0

This game which features a double under promotion.
(Chandler v Walker 1980's - I'm pinning again).
G.MacDonnell - H.Bird, England 1875
Black to play...

The whole game is very entertaining. Play it out, you will enjoy this.

G.MacDonnell - H.Bird

1.e4 e5 2.f4 exf4 3.Nf3 g5 4.h4 g4 5.Ne5 h5 6.Bc4 Nh6 7.d4 d6 8.Nd3 f3 9.g3 f5 10.Nc3 fxe4 11.Nxe4 Nf5 12.Kf2 Be7 13.Nf4 Rh7 14.Ng6 d5 15.Nxe7 dxe4 16.Nd5 Be6 17.Bg5 Bxd5 18.Bxd8 e3+ 19.Kg1 Bxc4 20.Bg5 f2+ 21.Kh2 e2 22.Qd2 f1N+ 23.Rhxf1 exf1N+ 24.Rxf1 Bxf1 25.Qe1+ Ne7 26.Qxf1 Nbc6 27.d5 Rf7 28.Qc4 Ne5 29.Qxc7 Nf3+ 30.Kg2 Rc8 31.Qa5 Rxc2+ 32.Kf1 Nxg5+ 33.Ke1 Nf3+ 34.Kd1 Rd2+ 35.Kc1 Nxd5 36.a3 Rc7+ 37.Kb1 Nc3+ 38.bxc3 Re7

This one is good. S.Shipov - V.Gagarin, Moscow 1994
It starts in this position.

55...Rxc3 56.Rxc3 Ne2+ 57.Ke5 Nxc3 58.b6 Na4 59.b7 Nc5

And Black must have very pleased with himself, he calculated
to get here thinking of a Knight fork on d7 and 0-1. White to play

60.b8=N -

Surprising how many players never even considered an under promotion.
Z.Almasi - V.Nevednichy, Ohrid 2001.
Here White thought he would use the skewer to pick up the
promoted piece when it appears on g8.
White has just played 50. Rc4-c8.... (50.Rc1 would have drawn).

50...g1=N+ 1-0

A.Santasiere - F.Marshall, New York 1931.
White was showing off here. Maybe he was teasing Marshall.
The win is quite simple. 79.Rf5 to stop the checks, 80.h7, 81.Kh6 and 82 g2.

79.Rf8+ Rxf8 80.g7+ Kh7

Now promoting to a Queen or Rook would be stalemate.
Taking a Bishop would actually be a quicker and neater win.
81.gxf8B Kg8 82.Kg6 Kh8 83.Bg7+ Kg8 84.h7 mate.

Instead White took a Knight 81.gxf8N+ Kg8 82.Kg6 Kh8 83.Nd7 Kg8 84.Ne5 1-0

An under promotion mate. A.Sandrin - P.Le Cornu, US Open 1949.
White to play.

27.Rh8+ Bxh8 28.f8N mate.

OK I'm bored with this now.
One last one and this is a classic from the great days of old.
White under promotes for one spite check and then allows a mate.
Play over and enjoy.
L.De Labourdonnais - A.McDonnell,London 1834

L.De Labourdonnais - A.McDonnell

1.e4 e5 2.Bc4 Bc5 3.Qe2 Nf6 4.d3 Nc6 5.c3 Ne7 6.f4 exf4 7.d4 Bb6 8.Bxf4 d6 9.Bd3 Ng6 10.Be3 0-0 11.h3 Re8 12.Nd2 Qe7 13.0-0-0 c5 14.Kb1 cxd4 15.cxd4 a5 16.Ngf3 Bd7 17.g4 h6 18.Rdg1 a4 19.g5 hxg5 20.Bxg5 a3 21.b3 Bc6 22.Rg4 Ba5 23.h4 Bxd2 24.Nxd2 Ra5 25.h5 Rxg5 26.Rxg5 Nf4 27.Qf3 Nxd3 28.d5 Nxd5 29.Rhg1 Nc3+ 30.Ka1 Bxe4 31.Rxg7+ Kh8 32.Qg3 Bg6 33.hxg6 Qe1+ 34.Rxe1 Rxe1+ 35.Qxe1 Nxe1 36.Rh7+ Kg8 37.gxf7+ Kxh7 38.f8N+ Kh6 39.Nb1 Nc2

A brilliant game of Chess.

And now the GOOD NEWS and the BAD NEWS.

A nice game in this Weekend's SCOTSMAN written by Paul Motwani.
Here, play this out.
V.Kovacevic - H.Ree, Maribor 1980.

V.Kovacevic - H.Ree

1.d4 d5 2.Nf3 Nf6 3.Bf4 e6 4.Nbd2 c5 5.e3 Be7 6.c3 0-0 7.Bd3 Nbd7 8.h4 b6 9.Ne5 Nxe5 10.dxe5 Nd7 11.Bxh7+ Kxh7 12.Qh5+ Kg8 13.Nf3 f6 14.Ng5 fxg5 15.hxg5 Rf5 16.Qh7+ Kf7 17.g6+ Ke8 18.Qxg7 Bf8 19.Qh8 Rg5 20.Qg8 Nxe5 21.Bxe5 Kd7 22.Rh8 Bb7 23.Qh7+

if 23...Qe7 24.Bf6! 1-0

The critical position is here with Black to play his 13th. move.
Black played 13...f6. Paul points out the defensive resource
13...Ba6 the idea is, if 14.Ng5 then 14...Bd3 holds h7.

A defensive idea well worth remembering.

If White spots this idea and plays 14.0-0-0 then 14...Be2!
pins the Knight on f3. So White has to play 14.Rd1 then the
attack can continue.

So I was wondering what would have happened if Black had slipped
in these couple of moves. Remember one of the bad things from the actual
game was the loose Black Bishop on b7. Now there is no loose Bishop.

However pulling the Rook to d1 has brought a new twist.
Play out the game again, this time 13...Ba6 and 14 Rd1 have been played.

and mate next move. A nice instructive game that one.

(and what about the Bad News?....ED)

Oh Yeah. The Bad News

White made that look frightenly easy.
I fear more converts to the London system (3.Bf4) has just been born.

The Board from j-bay puzzle solution.
Cut out the pattern shaded in red and pink and fit them together.
