Calculation training...Russian style !

When I was younger, I took some correspondence chess classes where the author claimed that Russians used to practice calculation with positions that were just too hard to be fully calculated. The point wasn't to find the truth of the position, but to try and develop your calculation powers in the process.

Though I don't claim today's example belongs to this category, I think it will provide a good exercise for most people who haven't reached master level just yet. (For others, please have a look there for more challenging examples )

So, here is how to make good use of this position :

• make sure you have at least 10 minutes available
• try to calculate as in a real game
• pick your main line (best moves for both sides) and evaluate the resulting position
• write it, as well as all the variations you've calculated

Then check your notes against your favourite engine, and enjoy the results Please do not post engine's analysis in the blog so that other readers can give the exercise a try as well.

Black last move was 19...Nf6-e4!?

Good luck and have fun !

And here is a more complete analysis of this critical position (with computer checking). The bottom line is : white is better almost everywhere ...

First, here is what happened during the game and what I calculated (as best as I can remember it)... I'll put up a more complete analysis with my comments later :

Nice example.But I am reaching nowhere with my calculations.A little help wud be nice.

The candidate moves here, I believe, are:-1.Bxe4, 1.Nxe4 and 1.Bxc8

1.Nxe4 line gives me nothing after 1.Nxe4 Bxf5 2.Rg6 Bxe4 3.Rxg7+  Kh8 4.Rg6+ Rxe5.Maybe I missed some winning variations, but it isn't likely.

The 1.Bxe4 line looked interesting.1.Bxe4 dxe4 2.Nxe4 f6 3.Nxf6+ gxf6 4.Rg3+ Kf7.And now what?

1.Bxc8 too loses.

So it comes down to this:- which was the move you played?

No, I didn't : maybe it was a twin

A good protocol for studying calculations. Now if would only get off my lazy and learn how to use Fritz 13 better.
