History
Known since the mid-19th century, this debut was widespread at the beginning of the 20th century and was actually considered a refutation of the royal gambit. In the future, however, opportunities were found for the development of the initiative for whites, as a result of which the defense of Schallop lost its former popularity and is now quite rare in tournament practice.
Debut Ideas
3. 3. Qg8-f6 Black attacks the white pawn, after which, as a rule, he transfers the knight to the h5-square, providing protection for his own pawn. The disadvantages of this system include the passivity and poor position of the horse at the edge of the board. Despite this, modern theory regards this opening as quite acceptable for black.

Systems with 4. e4-e5
The most popular sequel to the multi-branching option.
- 4. ... Nf6-d5 5.c2-c4 Nd5-b6 6.d2-d4 d7-d6 7.e5: d6! - with an advantage in white [1] .
- 4. ... Nf6-e4 is the move of Averbach . Possible extensions:
- 5. d2-d4 d7-d5 6. Bc1: f4 c7-c5 7. Bb1-d2 Bb8-c6 8. Bf1-d3 - White has an advantage.
- 5. d2-d3 Кe4-g5 6. Сc1: f4 Кg5: f3 + 7. Фd1: f3 d7-d6 8. Сf1-e2 or 8. Фf3-g3!
- 4. ... Nf6-h5 - the classic position of the defense of Shallop (see diagram No. 2).
- 5. g2-g4 ?! - so-called Tashkent option. Considered risky for whites.
- 5. Кb1-c3 - requires exact game from Black so as not to worsen his position. The main sequels:
- 5. ... d7-d6
- 5. ... d7-d5
- 5. d2-d4 - a move leading in a double-edged game. For a successful outcome, White needs to maintain his position in the center. Blacks usually respond by 5. ... d7-d5 (or 5. ... d7-d6 ). Possible continuation: 6. Фd1-e2 d6-d5 7.c2-c4 Сc8-e6 8.c4: d5 Сe6: d5 9. Кb1-c3 Кb8-c6 10. Сc1-d2 Сf8-b4 11. Кc3: d5 Фd8: d5 12. 0-0-0 0-0-0 with a difficult game.
- 5. Bf1-e2 - White seeks to threaten the h5-knight. Until the mid-1960s, this option was considered advantageous for Black, after which past opportunities were found to equalize the game and even gain a debut advantage. Possible extensions:
- 5. ... g7-g6
- 5. ... d7-d6
- 5. ... g7-g5! - modern theory recognizes this answer as the strongest in this position. Further it is possible:
- 6. 0—0 Rh8-g8 7. d2-d4 d7-d5 - with advantage over Black. At the same time, White has the opportunity to create counterplay by 8. c2-c4!
- 6. Nf3: g5 d d8: g5 7. 2e2: h5 gg5: g2 8. dd1-f3 gg2: f3 9. hh5: f3 bb8-c6 - with Black's advantage.
- 5. Qd1-e2 !? - move Keres [2] . White strengthens the center, after which they prepare the breakthrough g2-g4 .
- 5. ... Bf8-e7 - this continuation is considered the most optimal.
- 5. ... g7-g6
