(This is the simplest kind of Pawn centre that White can set up.)
Then Black hits back at it.
Black's pieces are all on good squares and Black even has a share of the centre. White can try and grab more of the centre than this, but the more White tries to grab, the bigger target you have got!
This is quite a fun idea and often leads to more unbalanced battles than boring old 1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5...
[I must add that there are lots of ways to unbalance the old Italian game (4. c3, 4. b4) and you can always try something else at move 3 (3. Bb5, 3. d4)]
- It is unusual and White may not have a clue how to behave
- It is difficult and unbalanced and so is a good system to play for a win with.
- White is given a free hand to set up the centre just as they like.
- White holds the centre so it is much easier for White to get pieces from one side to the other.
- White can use the big centre to attack down the middle of the board with e4-e5 or f4-f5
- Black has weakened the King's-side and White has a little start towards a King's-side attack down the h-file.
Juniors and amateurs may have much more fun, and learn much more about the basics of chess, when playing the familiar open games beginning 1. e4 e5. One more caution:
White plays a direct attacking line against Black's hypermodern opening.
White breaks in the centre.
7.e5 dxe5 8.dxe5 Nd5 9.Bd2 Nb6 10.0-0 f6
Black shouldn't open lines on the King's-side, that's just what White wants!
11.exf6 Bxf6 12.Ng5 e6
White plays a temporary sacrifice: White's centralised pieces can attack Black's King while the Black Queen's-side pieces cannot get back to defend.
13.Nxh7! Kxh7 14.Qh5+ (at this point Erik ceremoniously tore up his score sheet) 14...Kg8 15.Qxg6+ Bg7 16.Qh7+ Kf7 17.Bg6+ Ke7 18.Qxg7+ Kd6 19.Ne4+ Kd5 20.Qc3 Qe7 21.Qb3+ Nc4 22.Qb5+ Kd4 23.Bc3+ (Resigns)
[23.Bc3+ Ke3 24.Rae1#]
Rather an abrupt game. Now, most of your opponents can't play as well as Alec Charity, but if Erik can be blown away using this defence so can you. What went wrong here? Well, if you think about it, White's most basic plan in the opening is:
1. Develop quickly and grab as much of the centre as you can
2. Use your development and space advantage to attack the opponent's King
3. Attack by opening up lines for your better pieces.
Now, in the Modern Defence Black seems to help White do all these things! All right, it isn't quite that simple, but if White is determined to attack Black it is very difficult to stop it happening, and there are several sharp White systems which come very close to delivering mate almost by force. All you need is one little mistake and Black is finished.
In playing the Modern Defence you are playing a very risky, dangerous system with rules all of its own. To rub this point in, I give below a few master games where strong Black players just get smashed right out of the opening (Hue-Donner, Hessmer-Haefner, Fischer-Udovcic). You must be aware that this can happen to you, and what the do's and don'ts are of these positions.
Here's Steve Haataja:
Good lines, in some sense, are ones that your usual opponents cannot refute. If you are having trouble dealing with early queen sorties, then your opponents are playing "good lines" by bringing out the queen early. If handling this situation gives you trouble, I suggest playing more offhand games against players who do this, and trying it out some yourself. You will learn how to deal with such situations by a combination of observing others handle it and good old trial and error.
Here is a personal example. When I began playing the Modern Defence, things went pretty well at first. But then I ran into a fellow at the club who would quickly castle Queen's-side, play h2-h4, then h5. The h-file would open up and he'd checkmate me in maybe fifteen more moves. These were five-minute games, BTW. He did this to me several times that first night.
It became terribly frustrating. Nobody else attacked as savagely as he did, and I did fine against less violent variations. He went so far as to play 1.e4 g6 2.h4 (a slap in the face) a couple times, with great success. But after about four weeks of beatings, I finally timed the counter-punch in the centre correctly (the general principle: counter a flank attack with play in the centre). His attack lost steam and I won. He soon stopped single-mindedly playing for checkmate down the h-file as I was winning every such game. That was one of the best chess lessons I ever learned. Quickly hitting back in the centre became an instinctive reaction to the dreaded h2-h4. You can read the principle 100 times in books, but until you actually experience it firsthand, it's just somebody else's theory. -- Steve Haataja
This is the most modest centre that White can build up. Black can easily get a share of the centre with ...e7-e5 but that doesn't do the Bg7 any good, so Black must also be careful to keep White's pieces under control and look for any active play that is going. It's actually quite an annoying system to play against! (See the games Cramling-Yrjola, and Kauranen-Richardson)
This is another quiet system - White does not bite off more than can be chewed, and supports the d-Pawn against any pressure from the Bg7. Black can play ...c7-c5 and/or ...e7-e5 which may open up the long dark diagonal again. (See Filip-Bronstein).
This centre takes a little while to set up but is quite solid and can be dangerous once White gets some pieces behind it. Black must hit back with moves like ...c7- c5 and ...e7-e5. (See the games Stein-Suttles and Byrne-Donner below.)
This is one of the most dangerous systems for White (as we saw in Charity-Teichmann), and many Black players try to move into a solid Hedgehog or Gurgenidze system in response (Games: Hedgehog: Barczay-Ivkov, Keres-Navarovsky, Engedal-Davies, Gurgenidze: Herrera-Garcia)
White can play quietly behind this centre but can also use it to launch a King's-side Pawn storm with moves like g2-g4 and h2-h4. Black must try to keep this storm under control while hitting back in the centre or on the Queen's-side.
White can transfer the weight of the attack to the Queens'-side by playing c1- c4 before developing the Queen's Knight. This can be very like - even become - lines of the King's Indian Defence (Games: Korchnoi-Fischer).
This is the most common sort of central counter-attack. Black must be careful to get the King out of the way before opening up lines in the centre. (Games: Kauranen-Richardson, Cramling-Yrjola)
This is a very solid system which Black players often play against dangerous White systems like the Pseudo-Austrian. Black should aim to hold things tight on the King's-side and gradually move into White's Queen's-side.
This is almost a separate opening, and can actually arise commonly from the Caro-Kann Defence. Below I give several whole games to give you a feel for this way of playing, and if you want to take up this strategy, I recommend you play over all of them (as notes to Herrera-Garcia).
Black hopes to make trouble on the Queen's-side - either opening a file or nudging the Knight away from the defence of e4. Black must be careful though, because White can also try to make use of open lines there if White has not castled Queen's-side. But if the White King is to be found there, the Black Bg7 is already pointing straight at him!
Black can set this arrangement up against more or less any White system. It is not a strategy in itself, just a way of waiting. It is very flexible and Black can try to make a break at any point on the board, but Black can get stuck without any active play because Black cannot get enough pieces to any one spot on the board. White can then pick a time and place to break through. So Black cannot just curl up, but should aim to break up White's centre with moves like ...c7-c5 (Games: Barczay-Ivkov, Keres-Navarovsky, Engedal-Davies).
The Pirc Defence is usually played with the move order 1. e4 d6 2. d4 Nf6 3. Nc3, which stops White moving into a Queen's-side opening with c2-c4. With a Modern Defence move order White can play something like 1. e4 g6 2. d4 Bg7 3. c4 when a later ...Nf6 will transpose into the King's Indian Defence. This is a good fighting defence to the Queen's-side openings, which many Grandmasters like to play, and usually begins 1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 (see Korchnoi-Fischer).
If you don't like playing the King's Indian Defence (it is very complicated - whole books have been written about single variations of the Defence!) but still want to play the Modern Defence, you don't have to play ...Nf6 and instead you can find some other move after 1. e4 g6 2. d4 Bg7 3. c4 d6 4. Nc3, like 4...Nc6, 4...Nd7 or even 4...f5. On the other hand, Black's side in these various lines of the Averbakh Variation can be tricky to handle.
One clever move order is 1. e4 g6 2. d4 d6 3. c4 when 3...e5 is the idea. If White now pushes on here with 4. d5 you can play 4...f5, and if White plays 4. dxe5 dxe5 5. Qxd1+ Kxd1 then your King's Bishop can come out to c5 instead of being stuck on g7. If you don't want to White to be able to move over to a Queen's-side opening at all, you can always play the Pirc Defence with an early ...Nf6 and Nb1-c3.
Weakening the King's-side even more; 5...c6 6. g5 Nfd7 is better, or 5...Na6 planning ...c5.
Oddly, in reply to 5. h4, Black can reply 5...h5, because it is difficult for White to open a file without creating weaknesses in White's own position. 5...c5, hitting back in the centre, is also a good reply.
6.h3 c5 7.d5 0-0?
Having weakened the King's-side so much, that's the last place Black should put his King! Perhaps Jan thought that White had given up the idea of a King's-side attack after 6.h3, but...

Black's split Pawns are not weak because White is not organised to attack them - in fact, the half-open b-file gives Black a little initiative. 16.Bd2 Ba8 17.Nc4 Nh5 18.Be4 Bd5 19.b3 Rfd8 20.Rad1 Nf6 21.Bc2 Qb7 22.Na5 Qb6 23.Nc4 Qa6 24.Ne3 Qxe2 25.Rxe2 Bc6 26.f3 a5 27.Be1 Rxd1 28.Nxd1 a4 29.bxa4 Ra8 30.Bf2 c4 31.Bd4 Nd5 32.Bxg7 Kxg7 33.Be4 Rxa4 34.Bxd5 Bxd5 35.Ne3 Bc6 36.Rc2 Kf6 37.Kf2 Ke7 38.Ke1 Kd6 39.Kd2 Kc5 40.Kc1 Ra8 41.Rd2 f5 42.Rd4 Ra4 43.Kb2 e5 44.Rd8 Ra8 45.Rxa8 Bxa8 46.Nd1 Bc6 47.Kc1 g5 48.Kd2 Bd7 49.Ke2 f4 50.Nb2 h5 51.Kf2 g4 52.g3 Bc6 53.fxg4 hxg4 54.gxf4 exf4 55.Kg1 Bf3 56.Kf2 Be4 57.Kg1 Bc2 58.Kf2 Bb1 59.a3 Bc2 60.Ke1 Kd5 61.Kf1 Bd3+ 62.Kf2 Bg6 63.Nd1 Be8 64.Nb2 Bb5 65.Ke2 Ke4 66.Kf2 Kf5 67.Kg1 Kg5 68.Nd1 Kh4 69.Kg2 Ba4 70.Nf2 g3 71.hxg3+ fxg3 72.Kg1 Bc2 73.Kf1 gxf2 74.Kxf2 Kg5 75.Ke3 Kf6 76.Kd4 Bb3 77.Kc5 Ke7 78.a4 Kd7 79.a5 Kc7 80.Kb5 Kb7 81.Kc5 Ka6 82.Kb4 Ba2 83.Ka4 Bb1 84.Kb4 Bd3 85.Ka4 Bc2+ 0-1

[16.Bxf8 bxa1Q 17.Qxa1 Nxf8 18.Nh6+ Kg7 19.cxb4 Kxh6 20.dxc5 Wade says this is better for Black.]

Black wants to keep the 'good' light-squared Bishop on the board. It's not quite a King's Indian but in this game Black eventually fires off a classic KI-style King's-side attack. (Compare Korchnoi-Fischer 1970) 11.Nd2 Nh5 12.g3 a6 13.Bf3 b5 14.a3 Qe8 15.Qe2 Nf6 16.b4 h5 17.Nb3 Ng4 18.Nb1 f5 19.exf5 gxf5
Recapturing with a Pawn leaves Black in control of lots of central squares, and gives him the g-file to attack down. 20.Bg5 Bf6 21.Bxf6 Nxf6 22.Bg2 Qf7 23.Qd2 Kh7 24.Na5 Rg8 25.c4 bxc4 26.Nc3 h4 27.Kh1 Qh5 28.Qe2

Black blocks the Queen's-side so it is harder for White to attack there. 10.a3 Ne8 The Knight gets out of the way of the f-Pawn. 11.b4 b6 12.Rb1 f5 13.f3 f4 14.a4 g5
In this typical King's Indian position with a blocked centre, it's as if each side has their own private arena for action. 15.a5 Rf6 16.bxc5 bxc5 17.Nb3 Rg6 18.Bd2 Nf6 19.Kh1 g4 20.fxg4 Nxg4 21.Rf3 Rh6 22.h3 Ng6 23.Kg1 Nf6
24.Be1 Nh8 The real Grandmaster touch. 25.Rd3 Nf7 26.Bf3 Ng5 27.Qe2 Rg6 28.Kf1 Nxh3 29.gxh3 Bxh3+ 30.Kf2 Ng4+ 31.Bxg4 Bxg4 It's easy to see the appeal of the KID after such a game. 0-1
