Computer Training Method an Experiment

I believe I have it now. It is a good exercise to try to cough up a replayed game "from scratch".

A well-played and well-annotated game by D.T.; with many diagrams, I think it's a good method (I have not used a real board for it). However now when trying to replay it, I cannot recall at what exact moment Black played the slightly unhandy move Na5... (because I only have clicked through it a few times, and did not make the moves myself)

In the ...[text shortened]... P4/2P5/PP3PPP/RN3RK1 b - -[/fen]

17. ... Kg8 18. Qh8+ Kxh8 19. Nf7+ Kg8 20. Nxd6

I think that last tactic (Qh8+/Nf7+) actually appeared in a Spassky-Petrosian game?! Maybe GP or someone else can confirm this?

It's a really good shot and seeing these patterns repeated time and again is what eventually improves our tactical ability.

Overall, I very much like the idea of this teaching method. 🙂

Yes (not sure of the exact players) but here it is only an exchange. In the game you are referring to, it was led in quite handily by the White player so that he won a full piece.

Google says one option is Petrosian - Simagin, Moscow 1956.



1. Bxe5+!

and then paste it into your address bar and click Go. It definitely works as I've just checked it : )[/b]

I have done that before my previous post; something is wrong with my explorer then, for I always end up with Jacob Aagaard Kelvingrove Museum Simultaneous; I will try on Monday with other pc.

Yes, T.V. Petrosian - B. Spassky, Moscow 1966:



1. ? 🙂

That certainly looks like the game. Could've sworn Spassky was involved?! Oh well, old man's memory!
Thanks for that though Heinzkat : )

It appears Petrosian pulled that trick twice, with ten years in between.

Cheers heinz.

You are correct there is a never anything wrong with pointing out
a 'silly' tactic. You can never have too many ideas and patterns.

I could have taken that further as it's an instructive point
and a good example of a Liiqudation Combination.

Infact I'll go and change it now.

If there has been an early resignation I always go on to show a
plausible end. I could not spot a quick mate so ended it there.

That same idea was missed in a World Champion match by Alekhine
v Euwe (or was it Euwe who missed it?).
Odd, I cannot tell you with 100% certainty who missed it (well truth be told they both did).

But I can recall Purdy's notes when the combination, which stayed
in the postion for a few moves, was 'accidently' thwarted by another move.

"The nightmare is finally over."

Sometimes you won't get onto C.C. if i'm posting another article.
I did update last night about the visit to Edinburgh of Tiger Hillarp Persson

Done - final instructive miniature now reads.



with note;

Black actually resigned at move 13.Qh5+ I carried on for few moves
to show you the mess Black is in. he is down the exchange and two pawns.

Also be aware of the little liquidation combination 17.Qh8+ that was
added at the end to completely kill off any further resistance.

Now...was it Alekhine.......or was it Euwe.........

Tried replaying it again after a good night's rest.I played black's Na5 idea before e6 and the exchanges on f3.
Other than that it still sticks 🙂

Hi

These other posts about the Knigt fork have just apppeared
whilst I was writing the previous post.

Possible universal blind spot here involving Knight forks

Now...was it Alekhine or was it Euwe.....?

Can't be arsed to look it up but I bet it was Euwe.While he was a good tactician he was often blind to his opponents tactical possibilities.Always found that a rather odd shortcoming for a player of his stature.

A. Alekhine - M. Euwe, wch (game 16) 1937.

Position after 25. ... Qe5



White gets two chances for Qh8+!
