It all started in Boston in 1967 The first time a computer beat
a human being (one of the fleshy ones) in a tournament game
MacHack IV - Ben Landy, Boston 1967.
We join the game just asMacHack is wrapping it up.

Since then the computer has continued chipping away at the human ego,
another landmark was reached in the 1990 World Chess Championship.
Karpov - Kasparov, World Chess Championship (Game 15) 1990
The game was drawn but the computer Mephisto pointed out a missed
Karpov win. Ray Keens in his book of the match said that this was the
‘ultimate humiliation for a human being.’ Now we know different, the
machines were sending us a warning now the machines are unbeatable.
Here is the missed win (apparently missed by all the commentators as well)

[FEN "1r1r4/p3n3/1p3kp1/8/4P1b1/3BKN2/P4P1R/1R6 w - - 0 25"] 25. Nd4 Rb7 {Karpov played f3 here. Mephisto came up with this very pretty variation.} 26. Rh4 Rbd7 {If instead Bc8 then f4 gives White an overwhelming position.} 27. e5+ {Possibly rejected by Karpov because it gives the Black Knight freedom. There are some nice mates in here.} 27... Kg5 {Kxe5 also leads to completely lost position after Rb5+} 28. Rxg4+ Kxg4 29. Rg1+ {Kh3 or Kh4 or Kh5 all meet the same reply.} 29... Kh4 30. Rh1+ {Kg5 White mates with Nf3+ and Rh4 mate.} 30... Kg4 31. Be2+ Kg5 32. f4# {Checkmate. Computers still show these missed variations to the younger chips when they come off the production line.}
After all the drama of the 2016 World Championship it’s good
to get back to normal. But remember Carlsen’s Queen sacrifice.
M. Carlsen - S. Karjakin Rapid Tie Break (Game 4)
50.Qh6+ gxh6 51.Rf7 mate or 50....Kxh6 51. Rh8 mate.
Clever and very pleasing....and we have a mirrored doubler!
A.Vyzmanavin - V. Tukmakov, Ukraine 1986
White sacced a Rook trying to get a perpetual....
...he nearly succeeded but it’s Black’s move (see it?)
Sad to hear that during the World Championship Mark Taimanov,
Russian Chess Grandmaster and Music Maestro had passed away.
Here he Mark Taimanov (left) playing a young Spassky in 1954.
And on the cover of a CD dedicated to the worlds greatest pianists.
A very enterprising and astute player always on the look for a tactic.
“Always the optimist,” is how Bronstein describes him when noting
up one of Taimanov’s games in his book on the 1952 Zurich Candidates.
In that book Bronstein often indulged in very instructive flights of fancy
and you do get the feeling he enjoyed adding notes to Taimanov’s games.
M. Taimanov - Y. Averbach (round 6) Zurich 1953 (White to move)
Taimanov played 27.d7 spotting a nice double trick shot in the position.
Bronstein asks us to imagine it is White’s move so we can see the threat.
29.Qxf8+ Kxf8 30.Bxf6
That is a White win, Bronstein then shows us what Taimanov was thinking.

Kc6 Qc3+ {The White King is forced onto the b-file and Rb1+ will win the Queen and then mate White.}
Back to Mark Taimanov here he pounces on a very slack ‘obvious move’.

Kg3 {Seems OK it stops Rh4 allowing Rg4 when the Rooks gets behind the passed pawn. Can you see Black's reply.} 63... Rbh2 {OOPS! White resigned. Nothing can stop R8h3 mate. Every move is a potential blunder, try to avoid them (if only we could) and try to spot them when your opponent slips up.}
Between 1975 and 1979 World Champion Karpov lost just 7 games with Black
(He won 44). This one of the seven losses. Taimanov sets Karpov a cunning trap
and Karpov walks into it. If World Champions can stub their toe, then so can you.

Ng3+ {White has to take that, Qxg3 drops the b1 Rook but White can play...} 39. hxg3 Ra8 {Stopping Rh8 mate is going to prove difficult, even for a World Champion. Karpov realised this and resigned after Ng3+.}
****The Knights of Agincourt ****
This piece was inspired by this t-shirt design.
There is an Agincourt Variation of the English Opening but I thought I would
see if I could find an RHP game where the Knights came out and fought first.
So I fired up the Database for the 2,100th time. (Chessbase keeps a record
of how times you open a Database) and I went looking for this RHP set up
Lasker tells us to develop our Knights before our Bishops so why not?

Re8 {A good move. Black can ignore the 'threat'.} 11. e5 {A genuine chess trap. A trap has to have a pitfall for the target player to fall into and a refutation that leaves the trap setter in a poorer position.} 11... Rxe5 {The target player happily jumps into the pitfall. 11...Ng4 and Black picks up the e-pawn with a much better position (and a pawn up.)} 12. Qxe5 {The trap is sprung.} 12... dxe5 13. Rxd8+ {Black resigned, it's mate next move.}
