From the game Samuel Reshevsky vs Henrique Mecking in the Sousse Interzonal (1967).

[fen "r2qnr2/1pnb1pbk/3p2pp/p1pPp3/2P1P2N/PPN1B1PP/3Q1P2/1R2RBK1 w - - 0 1"]

1.Na4 Na6 2. Rec1 Rb8 3.Nc3 Nf6 4.Qb2 Rg8 5.Qc2 Re8 6. Nb5 Bf8 (6... Bxb5 7.cxb5 Nc7 8.b4 axb4 9. axb4) 7. Bd2 b6

According to Reshevsky in his book "Art of Positional Play" black wants white to abandon his calm queenside expansion, so black forces white to play on the kingside. I suppose the queenside expansion was seriously dangerous as black decided to risk so much by playing ... f7-f5.

In the case of white passivity on the kingside, what sequence of moves could best represent the queenside expansion as winning the game for white? Using the computer help I imagined something like this: 21.Na4 Na6 22. Rec1 Rb8 23.Nc3 Nf6 24.Qb2 Rg8 25.Qc2 Re8 26. Nb5 26...Bf8 27. Bd2 b6. And here I believe that white fixed the queenside to his advantage. And if 26...Bxb5 27.cxb5 Nc7 28.b4 axb4 29. axb4 it is easier to see the rooks getting into action.

Are there better lines?

  • Welcome! I cannot follow the moves you give: 21.Na4 Na6 22.Rec1 etc, they do not seem to relate to the game diagram? – cousin_pete Mar 30 at 5:15
  • The position in the diagram starts at move 19, yet your analysis starts at move 21. Even reading the book, the Na6, does not move until move 39, so I am not sure what it meant by your computer analysis with the first move for black being Na6. – PhishMaster Mar 30 at 10:58
  • Please give him a chance to return and edit the question before closing it, or even downvoting it. – PhishMaster Mar 30 at 11:01
  • @PhishMaster I edited the question! – Marcelo Farias Mar 30 at 11:22
  • @cousin_pete The only thing I changed from the original position is the knight. Instead of ...f5, I played for black Nac7. This is where the diagram starts. – Marcelo Farias Mar 30 at 12:02

I am not trying to be hard on you, but to be blunt, this is one of the dangers of analyzing with a computer, and not having any understanding of the position. That line of analysis you give with 20...Nac7 and then shuffling around the pieces, frankly, did not make any sense at all plan-wise (and even my Stockfish 11 does not agree with your computer's line). I will discuss that in my notes to the game.

I opened my copy of that book, and what Reshevsky, correctly, said was that white has move space on the queenside, and that black needs to look for play on the kingside with f5. White's play, in theory, is generally better, but what Reshevsky also said is that if white blindly pursues his own play on the queenside without any regards to his own king, he can easily lose to a direct attack. That is a common theme in the KID, especially the Classical variation. I have seen many games where white has a Na8, and is up a rook, but is helpless against the mating attack all the way on the other side of the board.

Here are Reshevsky's own words:

enter image description here

Reshevsky chose to play a line that he was well-prepared for f5, and then actually chipped away at f5, weakening e4, which led to the black king. In the vast majority of KID games, that is not the typical line of play, and white does not often get to be that active on the kingside. In most, white owns the queenside, and black owns the kingside, and each side tries to open their dominate side of the board. In most cases, going passive on your better side, and trying to just defend the other side where your opponent is better, is a recipe for a loss.

    Thanks. The commentary was very helpful. The main issue was how to open the files with advantage. For some reason (maybe not to open up the black rook) my computer did not want to open the queenside. I thought that having the queenside closed, but with a knight on b5 that I white ''couldn't'' take was the compensation somehow. – Marcelo Farias Mar 30 at 19:15
  • In general, when your major/heavy pieces have more scope, and there are open files, when they penetrate, they attack weak pawns, and when the opponent has to defend them, often something cracks eventually, and they cannot defend everything. You almost always want the area of the board that you are better it, to be opened up. Sometimes not right away since it may allow too many trades, but in the long run, you need that openness to penetrate, and create threats. – PhishMaster Mar 30 at 19:18
  • Also, computers sometimes see a space advantage, and say you have a +1.whatever advantage, but if you really cannot get in, there is no real advantage there in practice. – PhishMaster Mar 30 at 19:20
  • Oh. My question was really dumb. I didn't mean to ask what would happen if black was completely passive. What I wanted to ask is what if black played only on the queenside, could he shut down white, could he trade down everything for equality? Things already seem pretty closed on the queenside by the way. And Reshevsky said that white was forced to play on the queenside, but the way I see, It seems that black was the one forced to play on the kingside. – Marcelo Farias Mar 30 at 19:31
  • Also, could you suggest me an instructive game on the KID where black wins with the kingside attack? – Marcelo Farias Mar 30 at 19:34
