Hi

I am puzzled by a move in the game A. Karpov – V. Korchnoi, World Championship, Baguio City 1978

 

White’s move 26 Rd7!! Is stated to be an excellent move.  But I just can’t work why it is classed as an excellent move.  It seems to me to be a blunder as it is threatened by Black's Bishop at e6.

 

null

 

For reference the remainder of the game's moves were thus:

26 … Rb8

27 Nxf7 … Bxd7

28 Nd8+!  (Black resigns) 1-0

Ah, on reflection I think I see why 26. Rd8 was classed as !!

White wanted Blacks' Bishop at e6 out of the way so he could carry out 27. Nxf7 in safety.  White was sacrificing his Rook to allow his Knight to move safely.  Black didn't fall for it but instead went 26...Rb8

White must have thought on his 27th move, Let's do it anyway, and moved his Knight (27. Nxf7).  here he must have hoped that Black would take his Rook rather than his Knight.  Which, this time, Black fell for.  Black moves 27...Bxd7, enabling White then to move the Knight onto 28. Nd8+

If Black had taken the Knight instead of the Rook, that may have slowed White's plans.  Even if only for one or two moves. :-)

Grandmasters don't make moves "hoping" that their opponent will do something or another.

If Black takes the Rook immediately, white has

27. ...  Bxd7

28. Qxf7+ Rxf7

29. Rxf7#

So black doesn't take the Rook right away, however, White's move Rd7 is good for many reasons.  If black effectively does nothing (such as 27. ... a5), then the threat is taking on f7 with either the Queen or the Rook, for example:

27. ... a5

28. Qxf7+ Bxf7

29. Rdxf7+ Rxf7

30. Rxf7#

So try to stop this threat, black does 27. ... Rb8 (to give his King a square to move to - Ke8 - after the last Rxf7).  However, white is prepared for that.

After 28. Nxf7, white is threatening to move his Knight to d6 with a discovered check which also covers the e8 square.  For example:

28. Nxf7 a5

29. Nd6+ Rf7

30. Qxf7+ Bxf7

31. Rxf7#

And, of course, if

27. Rd7 Rb8

28. Nxf7 Bxf7

29. Rxf7+ Rxf7 (else, if 29. .. Ke8 30. Rxg7)

30. Qxf7#

Similarly, if

28. ... Rxf7

29. Rxf7+ Bxf7

30. Qxf7#

or

29. ... Ke8 and white is up a pawn and the exchange with the black King still in a lot of danger.

Yes, I am afraid so. Just learning and getting to grips with how to play the game.  But I’m gestting there. :-)

That’s exactly what I have been doing over the past week since joining this site and wanting to improve my game.  I knew how each piece moved from playing as a kid years ago, but that’s all I knew. Now, however, I want to improve my game by actually learning tactics >.<  I have several books on chess tactics, in which I am currently working through openings.  I also go through the lessons here on this site. I play the games out on my chessboard to actually visualise the moves. It’s vary helpful.  Even if I am the worst ever player on Chess.com, I’ll always love playing the game, and learning. happy.png

It's not that easy to see why Rd7 deserves its ! If you haven,t seen this kind of tactic before, but it is well worth learning this pattern. Your habit of consistently asking "why?" Will help you improve quickly, but you need to get in the habit of looking a bit deeper. If the question is "why can't the bishop take that rook?" The answer is usually because that bishop is already doing something important

 

That’s what I love about the game; there’s always something going on. At first glance it may seem like a bunch of randomly placed pieces, but look again and you start to see the ingenuity in the game.

Yes always check on papper, especially when trying to lord it over other people. Humility met narcisism here.

Suggest you start with easier tactics such as mate in two moves (and I don't mean chess problems, they are difficult!). There are a couple of books (by Fred Reinfeld) consisting of easy mates in 2. Or you might try Bobby Fischer Teaches Chess, not my favorite book but certainly not bad. Good luck.

The books I am currently studying are:

The Right Way to Play Chess, David Pritchard (paperback)

Logical Chess Move by Move, Every Move Explained, Irving Chernev (paperback) - my favourite

My 60 Memorable Games, Bobby Fischer (paperback)

The Mammoth Book of The World's Greatest Chess Games (Kindle)

Chess: the Art of Logical Thinking, Neil MacDonald (Kindle)

Tactics Time vol. I, Brennan & Carson (Kindle)

 

I also use the lessons here on Chess.com as well as playing my Xbox (Pure Chess), and the computer, again via Chess.com. I love the analysis option available at the end of each game - vary helpful indeed.

I am also studying the games of Nihal Sarin as it's extremely interesting watching and learning how such a young GM plays and thinks his games.
