Killegar Chess Presents: "My System" by Aron Nimzowitsch - Chapter 2, Part 2

Hello everyone, welcome to

part

two. This section is titled possible obstacles to operations on a file and are listed below: one, the block of granite and how to undermine it. two, the concept of protected and unprotected obstacles, brackets, pawns, close brackets, three, two methods of carrying out an attack on opposing pawns that are in the way The evolutionary and revolutionary attack Nimzovich begins this section by emphasizing how important The free access that we achieved in the last example returned, meaning that there was nothing in the way that should have been. Broken down, use the following diagram to show how often a heavy piece can be prevented from reaching the 7th or 8th rank simply by blocking the pawn and apparently proclaiming that the rook will get there over the pawn's corpse now if this pawn were protected by another pawn it would make no sense to try to attack it from the front since the piece would have to be sacrificed, it would be much smarter nimzovich writes to First undermine the support that the pawn you want to attack has, for example here, if white had an H pawn, he could advance it to H5 like he said he was on H2, you go H4 H H5 and attack this G6 pawn here, then you can play H takes G6 and you know a support pawn would have to recapture and then he can start properly attacking the G6 pawn with pieces , first moves here, but in this instance the pawn is unprotected anyway.

I think there should be a pawn on F7 here and then you can imagine the pawn marching up and then taking and then. he can attack the pawn G6 properly so we'll look at that in more detail in just a second so in this position the rook is attacking C6 but C6 is supported by B7 so you know unless the rook wants to sacrifice itself , uh, I'm not going to be able to take on C6, so the correct approach is to undermine the C6 pawn sport by playing B5 and nimzovich here makes a reference to his previous comment about the pawn being a solid defensive piece and that, instead, defending with pieces You know that defending pawns with pieces is almost a mistake because only a pawn can defend without complaining for a long period of time.

You know that pawns are designed to defend, among other things, and pieces are not designed to defend, they are designed, you know, to attack. and gain activity and goes on to say that to attack the pawns we must do it by accumulating pressure with our pieces and you know that if they advance they will generally be easier to attack and in any case it is better to stop them and prevent them from advancing before attacking them, which often happens anyway, it's just that, as a side effect, our opponent will respond by defending as often as we attack the pawns in question and an interesting fight should follow once there are the same number of attackers and defenders as us.

You can try to gain an advantage by thinning the ranks of the defenders, which can be done in three main ways: first, by chasing them away, second by exchanging, and third, by cutting off one of the defensive pieces. This process, therefore, transfers the attack to the opposing piece. to the defenders of that piece, you know what a logical step is and the ultimate goal is still to win both the material in question and break the resistance that our opponent has in that file so that we can occupy the first two places and the following is an example what nimich was talking about here white has reached a good final position again if you want to try to develop the winning strategy according to what we have been seeing then please stop the video now Rook H2 is the correct one move here because the process of what we're talking about, which is attacking this weak H6 pawn and you know we can do it directly because it's not supported by other pawns and it doesn't need to be. undermine first or something, so King H7 is the move made, Black would probably play to defend it.

The King G7 doesn't work because the f8 bishop will be needed to defend this pawn after a rook and H1, so now comes the f8 bishop and now the F5 knight. add a third attacker and you know, keep in mind that it can't be advanced or it just gets captured, so obviously that's not good, so black has to defend with one of his rooks, so let's say Rook B6, so Now there are three defenders, the bishop, the rook. and the King, as well as three attackers, the Knight and the two Rooks, so what is the way to continue now again?

If you want to try to detect it, then stop the video. D6 is simply the answer by removing H6's tower defense, which is leaving. fall and thus allow the decisive penetration of White into the 7th and 8th ranks with the rooks, okay, let's continue with the next example, here is another one, yes, this time it is much simpler, if you want to try to detect the move, stop the video again now. So if we take a look at it, we can see that the two white attackers, Black has two defenders, but we can eliminate one of them immediately with the knight E6, a pretty obvious check, so let's say that the king H7 now the knight takes d8, rook takes d8 and takes rook.

F6, so that's just a clear example of how to eliminate defenders by exchanging and you know that the last two examples are what nimzovich called evolutionary attacks, that is, the method of concentrating attackers on one point or piece with the idea of gain material or gain a positional advantage and you. I know that often both at the same time, the Revolutionary attack on the other hand is significantly different, okay so it's White that moves here and on the last move he played the Rook H2 with the idea of ​​doubling the Rooks in the H file to attack the H7 pawn and the square and the black king of course, so how does it continue now again?

If you want to try to solve it, then stop the video, so what do we have to consider here if we play a tower with H1? What happens after H6? You might well ask, even the F6 Knight, how can White continue to attack well? The answer is that White doesn't need to worry about any of that because, of course, he can play. The Rook takes control of H7, forcing mate on the bishop's next move. G8 covered, so the King taking H7 is forced and now the Rook H1 is mate, there are no squares for the black king, so playing, as I said, Rook with H1 is not so decisive because the Knight F6 or H6 and already You know, any of those have the effect. of creating a so-called granite block in the H file and it is much more difficult, although you know that it is obviously still winning, but it does not win as quickly and you know that the sacrifice that we saw was simple, but for nimzovich it was a very significant thing because it shows clearly the difference between an evolutionary and revolutionary attack, so let's take a look at another example in this position, White can follow the evolutionary attack to win, win H7 as follows: Rook, H1, stacking H7, you know, Knight . f8 is forced and now we can eliminate the defender with the bishop E7, so let's say the rook E8, the bishop takes f8, the king takes f8, the rook takes H7 and this is a probable draw, this position here neither side has a lot of advantage, okay, white has the H file, but that doesn't lead to much and black can win these central files, the pawns are equal and you know it looks like a tie from here however, of course, there is something much more strong than Rook to H1 again if you want to try to detect the movement and uh stop the video now this one is a little more obvious and easier and shows some of the dangers of losing your fan Shadow Bishop and allowing your opponent to have Bishop of that color.

Rook takes H7, of course, it's the move that's forcing mate in both. moves, you know, and as before, White forcibly clears the front ranks with a sacrifice to mate, so the king takes H7 is forced to R H1 to control the king G8 and the rook h8 es mate Nimzovich ends this section by making the observation that, generally speaking, the evolutionary attack will come before the revolutionary one, that is, by applying peace pressure on our opponent, we should be able to force his defensive pieces into uncomfortable positions where they interpose each other, as often the defending side will suffer from a lack of space after that. has been achieved, it should be possible to break through with a forced revolutionary attack, among other things and you know it goes without saying that we should be able to see these attacks within the positions and you know that is something that cannot really be taught to you You have to learn it through practice and sharpen your eyes and find those things for yourself.

Well, that's the end of
