The basic position of the Pirc defense after 3.… g7 – g6
The Pirc-Ufimzew defense is one of the semi-open games and is classified in the ECO codes under the keys B07-B09. It is often referred to as the Pirc defense , but is officially named after the master players Vasja Pirc and Anatoly Ufimzew .
Basics
The Pirc-Ufimzew Defense begins with the moves:
- 1. e2 – e4 d7 – d6
- 2. d2-d4 Ng8-f6
- 3. Sb1-c3 g7-g6
and is considered a comparatively risky opening at grandmaster level. Similar to the King's Indian Defense , White is initially given the center and taken up with the fianchetto , a knight on f6 and the pawn on d6.
Due to the reserved black structure, several (main) sequels are available to White:
- Byrne system: 4. Bc1 – g5 White wants to position this bishop in front of the f4 pawn
- Bishop system: 4. Bf1 – c4
- Classic system: 4. Ng1 – f3 (development plan: Bf1 – e2, 0–0)
- Fianchetto system: 4. g2 – g3 (development plan: Bf1 – g2, Ng1 – e2, 0–0 and possibly f2 – f4)
- f3 system: 4. f2 – f3 (analogous to the Samisch variant in King's Indian , White supports his center and will advance on the kingside with h2 – h4 and possibly g2 – g4).
- Attack 150: 4. Bc1 – e3 (development plan: Qd1 – d2, f2 – f3, long castling and attack on the kingside, analogous to the Yugoslav attack in the dragon variant ), as in the famous game Kasparow - Topalow, Wijk aan Zee 1999 .
- Three-pawn attack: 4. f2 – f4 (direct approach in the center and gain space with e4 – e5 and / or f4 – f5) Bf8 – g7 5. Ng1 – f3.
The immediate counterattack on white center c7 – c5 leads to entanglements like 6. Bf1 – b5 + (6. e4 – e5 Nf6 – d7 7. e5xd6 0–0) Bc8 – d7 7. e4 – e5 Nf6 – g4 8. Bb5xd7 + Qd8xd7 9. d4 – d5 d6xe5 10. h2 – h3 e5 – e4 or 8. e5 – e6 Bd7xb5 (f7xe6 9. Nf3 – g5 Bd7xb5 10. Ng5xe6 Bg7xd4 11. Ne6xd8 Bd4 – f2 + 12. Ke1 – d2 Bf2 – e3 + results in continuous check. White can try 11. Nxb5) 9. exf7 + Kd7 10. Nc3xb5 Qd8 – a5 + 11. Nb5 – c3 c5xd4 12. Nf3xd4 h7 – h5 13. Qd1 – f3 Nb8 – c6.
With 5… 0–0, however, black first completes his development before moving on to further activities.
- 4. Bf1 – e2 Bf8 – g7 5. h2 – h4 or 5. g2 – g4
The last four variants mentioned mostly lead to tactical positions and aim to attack the king directly, while the fianchetto system and the classic style of play lead to a calmer, positional structure of the game.
Parallels to other openings
The almost identical Modern Defense (1. e2 – e4 g7 – g6) mainly differs in that the knight is held back on g8, where it lingers for a very long time before it is later pulled away under other circumstances. Since the move 3. Nb1 – c3 is not forced to a greater or lesser extent by 2.… Ng8 – f6, White can take other options than in the Pirc, for example also playing 3. c2 – c4. After that, the King's Indian Defense often arises . In these three openings White has a space advantage with his pawn center, but Black can set the pawn advances e7 – e5 or c7 – c5 against it.
The Czech system (also called Pribyl-Pirc) represents an independent opening, which arises after the moves 1. e2 – e4 d7 – d6 2. d2 – d4 Ng8 – f6 3. Nb1 – c3 c7 – c6. The main variants are:
- 4. f2 – f4 Qd8 – a5 (followed by 5. e4 – e5, Bf1 – d3 or Lc1 – d2)
- 4. Ng1 – f3 Bc8 – g4 to play with Black's plan e7 – e6 and d7 – d5.
Furthermore, the following variant can be found in today's tournament practice:
- 2. d2-d4 Ng8-f6 3. Nb1-c3 e7-e5
This leads to an independent variant after 4. d4xe5 or to a Philidor defense after 4. Ng1 – f3 .
According to Jörg Hickl , the variant after 4. d4xe5 d6xe5 5. Qd1xd8 + Ke8xd8 is evened out, since Black's confinement is dissolved. Black normally builds up with Be6, Bd6, Ke7, h6, a6, Nc6 and can then attack the queenside with Rhb8 (the d-file is blocked by the bishop). The Doppelbauer after 6 L f1-c4 e6 7. Bc8-Lc4xe6 f7xe6 is not a real weakness as he controlled important fields in the center, which otherwise could occupy the white knight. In general, the transition to the Philidor defense is therefore considered to be more promising.
