The Maróczy Bind can be seen in other openings as well, for both colors, including the English Opening, the King's Indian Defence, and other lines in the Sicilian Defence. This bind is distinctive for two White pawns on c4 and e4 (c5 and e5 for Black), where they clamp down on the d5 square.
In chess, the Scheveningen Variation [1] of the Sicilian Defence is an opening that is a line of the Open Sicilian characterised by Black setting up a "small centre" with pawns on d6 and e6. There are numerous move orders that reach the Scheveningen; a common one is: 1. e4 c5 2. Nf3 d6
The Sicilian Defence is a chess opening that begins with the following moves: . 1. e4 c5. The Sicilian is the most popular and best-scoring response to White's first move 1.e4. The opening 1.d4 is a statistically more successful opening for White because of the high success rate of the Sicilian defence against 1.e4.
In chess, the Dragon Variation [1] is one of the main lines of the Sicilian Defence and begins with the moves: . 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 g6. In the Dragon, Black's bishop is fianchettoed on g7, castling on the king's side while aiming the bishop at the center and queenside.

The usual continuation is 3.exd5 Qxd5, a line known as the Barmen Defense. [3] 3.e5 may transpose to the Advance Variation of the French Defence if Black responds with 3...e6, but Black can also develop his c8-bishop before playing e6.

The Hedgehog Defence, in particular, refers to a variation in the Symmetrical English (1.c4 c5) where Black adopts this setup: 1.c4 c5 2.Nf3 Nf6 3.g3 b6 4.Bg2 Bb7 5.Nc3 e6 6.0-0 Be7 7.d4 cxd4 8.Qxd4 d6. Other openings where Black often uses the setup include the Queen's Indian Defence, and the Taimanov and Kan Variations of the Sicilian Defence.
Introduced by Weaver Adams during the middle of the twentieth century, this odd-looking pawn move has mostly been used as a surprise weapon to combat the Najdorf. Should Black continue with 6...e5 anyway, White can respond with 7.Nde2 following up with g4 and Ng3, fighting for the weak light squares by playing g5.
