I have another Instructive game from Olav Lange.
S. MacGilchrist (1574) - Olav Lange (1470)
Grangemouth Congress 2005
1.e4 e6 2.d4 d5 3.exd5 exd5 4.Bd3 Nf6
5.Bg5 Be6 6.Nf3 Nc6 7.0-0 Bd6 8.c3 Qd7
A brave choice. I would have played the same move.
9.Bxf6 gxf6 10.g3? ....
Why? I do not think Black will be castling K-side.
Re1 and Bf1 or b4-b5 then bN-d2-b3-c5.
10...0-0-0 11.Nh4 h6?
waste of time. You have to get rid of the h4 Knight so Ne7 - g6
and if Nxg6 or Bxg6 then capture back with the h-pawn opening up
the h- file and then, in the words of Fischer;
"...pry open the KR-file, sac, sac...mate." page 20, 60 Memorable Games.
(the original version, not the butchered tripe put out by Batsford
where they had the gall to alter large amounts of the text and even
'correct the analysis' .Which resulted in them 'correcting' a position
that never arose." Akin to a bunch of Philistines rewriting The Bible.
Setting a cheap should the Bishop go to h3 and then take
the Rook on f1 (Bf5+ wining the Queen)
12...Ne7 13.a4 Rhg8 14.b4 Bh3 15.Re1 Qg4
16.Rxe7 putting into action the trick set up on move 12
16...Qxh4 (16...Bxe7?? 17.Bf5+)
17.Rxf7 fritz suggests this lousy pawn grab.
17...Rde8 18.Na3 playing away from the action - a hard move to see.
Black has at least a perpetual. 18...Bxg3 19.fxg3 Rxg3+ 20.hxg3 Qxg3+
21.Kh1 Qf3+ 22.Kh2 Qf4+ 23.Kh1 etc.
(If the more plausible 18.Nd2 Bxg3 19.Bf5+ Kb8 20.fxg3 Rxg3+ 21.hxg3 Qxg3+ mates)
17.Bf5+ Kb8 18.Re3 Rde8 19.Rxe8+ Rxe8 20.Na3 (20.Bxh3 Qxh3 21.Na3 Qh5-+)
20...Qh5 21.Bxh3 Qxh3 22.Nb5 white has made things easier for himself
though I prefer Black - it's easier to play for White.
16...Ng6 17.Be2 Qg5 18.Nd2 h5 19.Nf3 Qh6
This is the critical position the next few moves will decide it.
Theory! (yes attacking theory) favours the attacker.
White has been defending for the past 6 moves.6 moves is a long
time for a 1574 player not to make a error. - It will come - have faith.
20.Ngh4 Nxh4 21.Nxh4 Qf4 22.Ng2 Bxg2 23.Kxg2 h4 24.Kh1 hxg3
25.fxg3 Rxg3 26.hxg3 Rh8+ 27.Bh5 Rxh5+ 28.Kg1 Rg5;
One fun line is 20.a5 h4 21.a6 b6 22.b5 hxg3 23.fxg3 Bxg2
24.Qf5+ Kb8 25.Qxd5 Qe3+ 26.Kxg2 Nf4+;
20.Qc1 is a tough defence to crack 20...Nf4 21.Nfh4 Nxe2+ 22.Rxe2 Qg5 23.Qe3
20...Nf4 Good keeping it as messy as possible.
and here at last is the mistake.
Now is Black up to the task does he realise his opponent
has just blundered, or will he miss it and lose the game and
then lose the next two games because he keeps thinking this game?
Better was 21.Nxf4 Bxf4 22.Qd3 h4 23.Bf1 hxg3 24.fxg3 Bg4
(24...Bxg3 25.hxg3 Rxg3+ 26.Kf2) 25.Bg2 Rh8 26.gxf4 Bxf3 27.Qxf3 Qxh2+ 28.Kf1
21...Bxg2! 22.Nxg2 Nh3+ 23.Kf1 Qxd2 24.Bxh5 Qxf2 mate.
Here is the complete game.

You just keep the pressure on and eventually a mistake will come.
And just to prove the point.

Me to play.
OK I took a few liberties in the opening 1. e4 d5 2 e5?!
but Shaun played really well in this game. So what to do?
Black has just played Bg5-h4!
Now I can 0-0-0 and it was this wee trap that made me lure
Black's Rook to b2 - I just have to get it right.
However I saw if;
1.0-0-0 Qb8! 2.Rxh4 Kd7 3.Rf4 Rxa2! 4.Rxf7+ Kc6 and Black wins.
I was crediting Black with finding these moves. He's playing
well enough to see I cannot play 1.Bxh4 Qxh4 2 Rxh4 Rg1 mate.
Then I saw 1.Bxh4 Qxh4 2.0-0-0 Qxf2 and Black is cruising.
So...1.Qh5 Qg5 (I only looked at 1...Bxg3 thinking I was winning
the exchange with Qh8+ though Black still makes it messy with
Bxf2+) 2.Qxh4 Qd2+ 3.Kf1 Qe2+ 4.Kg1 Qxf2 mate.
I missed the Bishop on g3 was going to get pinned. Huh!
Bothered? Not at all. What goes around etc etc.
Next game, same tournament.
A Tate (1894) G. Chandler (1864)
White played 1 Qe2 missing that the g-pawn was pinned.
1 Qe2 Qxh3+ mate on g2 next move.
