Morphy,Paul – Meek,A
This is really good game to show students the importance of a space advantage and how to use it.
1.e4 e6 2.d4 g6 3.Bd3 Bg7 4.Be3 Ne7 5.Ne2 b6 6.Nd2 Bb7 7.0–0
This seems to be an unorthodox way of developing pieces but it has the advantage of leaving White’s f-pawn free to advance.
Gaining space on Kingside
In chess a space advantage gives you more room for manoeuvre your pieces. And in general you should attack on the side where you have a space advantage.
Preparing the g4 lever. 10.exf6, taking on en passant, wouldn’t give much after 10…Rxf6.
The idea is to use the g-file for his rooks later on.
11…c5 12.c3 c4
It is not a good idea to shut the side of the board where you have space. Here it gives White a free hand to expand on the kingside.
13.Bc2 a6 14.Nf3
Improving the knight’s position and aiming to join the kingside attack.
14…h6 15.g4 Kh7 16.Rg1 Rg8 17.Qe1 Nc6
It would be better to play 17…Qe8 as moving the knight from e7 invites White to sacrifice on g6.
Let’s check some other alternatives too:
(1) 18…Nf8 19.gxf5 gxf5 20.Ng3 is a stunning knight sac which if taken leads to an immediate win: 20…Qxh4 (20…Ne7 21.Nhxf5 exf5 22.Nxf5 Nxf5 23.Bxf5+ Kh8 24.Bc2 with the idea of f5 is horrible for Black but it is still comparatively better than the text move) 21.Nxf5 Qxe1 22.Nd6+ Kh8 23.Nf7#.
(2) 18…Qe8 19.Nxg6 Qxg6 20.gxf5 Qe8 21.f6+ is just winning for White.
19.Nxg6 Kxg6 20.gxf5+ Kf7
If 20…Kh7 21.f6+ Kh8 22.fxg7+ Rxg7 23.Qh4 and White is winning
21.fxe6+ Kxe6 22.f5+ Ke7 23.Qh4+
White is also winning with f6.
23…Ke8 24.f6 Bxf6
If black tries to save the piece with 24…Bh8 then 25.Qh5+ Kd8 26.Bxh6 is winning.
25.exf6 Rxg1 26.Rxg1 Nxf6 27.Bg6+ Kd7 28.Bf5+ Ke8 29.Bxh6
29.Rg6 is better than the text move and after 29…Ng8 30.Bd7+! Kxd7 31.Qg4+ Ke7 32.Qe6+ etc.
Attacking both the knight and bishop.
After 30…Ng8 there follows mate with 31. Bd7+ Kf8 32. Qf4 Nf6 33. Qxf6#, so Black resigned.
