{ This chapter is on the Sicilian Alapin with an early c3. Although White does get a nice pawn center, the pawn on c3 restricts the White knight from coming to the important central square c3. The Alapin is considered a quiet sideline and Black can usually get a balanced position out of the opening. It is important NOT to exchange pawns with cxd4 too early or else white gets Nc3 afterwards. } 1. e4 c5 2. Nf3 ( 2. c3 e6 3. d4 d5 { Usually transposes after white plays Nf3. } ) 2... e6 3. c3 d5 { I recommend this line (And I play it myself!) because it doesn't require a lot of memorization of theory that comes with 3. Nf6, where white can get a strong initiative if black doesn't play accurately. } ( 3... Nf6 4. e5 Nd5 5. d4 cxd4 6. cxd4 d6 { Another solid line for black, but requires more opening study. } ) 4. exd5 ( 4. e5 { Against 4. e5, I recommend playing 4. Bd7 and 5. a6 with the idea of trading off the bad bishop immediately with Bb5. This has brought me good results and comfortable positions to play. See my game vs Bolzano-weierstrass below } 4... Bd7 5. d4 a6 6. Bd3 cxd4 7. cxd4 Bb5 8. Bxb5+ axb5 { Although black has doubled pawns, they aren't necessarily weak since black now has the wide open a-file and the b pawns stop the knight from coming out. } ) 4... exd5 5. d4 Nc6 6. Bb5 { The most challenging move. } ( 6. Be3 c4 7. b3 cxb3 8. axb3 Bd6 ) ( 6. Be2 Bd6 7. O-O Nge7 { Basically the same line as 6.

Bd6 7. dxc5 Bxc5 { Yes, white got a tempo on the black bishop, but the position is still balanced because white's c3 move blocks the knight from going there and black's isolated d-pawn is hard to attack. } 8.

{ The King's Indian Attack with 3. d3 signals a slow and closed game. My recommendation for black is to put a bind on the d4 square with a reversed Botvinnik English structure. That way, White will have a hard time opening up the position with d4 and the fianchettoed Bg2 will often be blocked by the pawn on e4, limiting it's scope. } 1. e4 c5 2. Nf3 e6 3. d3 Nc6 4. g3 Nge7 ( 4... g6 { Slightly inaccurate move order because this allows Bg5, where Black's dark squares are a bit too weak. } 5. Bg5 Nge7 ( 5... f6 6.

The e-file must stay closed! } 8. c3 O-O 9. Nbd2 d6 { Black has a very flexible position here with a slow kingside expansion plan of h6 + Be6 + f5.

{ 3. g3 is a tricky move order. White may be going for a King's Indian attack with d3, but playing d4 to transpose to an open Sicilian is also possible. Therefore, White's intentions are not revealed with this move, and Black has to be careful. } 1. e4 c5 2. Nf3 e6 3. g3 d5 { This is the recommended line against 3. g3. Black should punish White for not playing d3, so now Nbd2 is not possible. } 4. exd5 { Basically forced. } 4... exd5 5. d4 ( 5. Bg2 Nf6 6. O-O Be7 7.

{ With 6. Be2, White has the option to develop the bishop to f3. A drawback is the e4 pawn is weaker at the moment.

{ The Maroczy Bind setup has always been a very solid pawn structure for White, and leads to fairly slow and positional games. White keeps a steady bind in the center with the e- and c- pawns. My recommendation against the Maroczy in general is to play Bb4 whenever possible to annoy White by threatening to play Bxc3, creating double isolated c-pawns. If White stops Bb4 with an early a3, switch to a hedgehog setup where the a3 move doesn't really help White. } 1. e4 c5 2. Nf3 e6 3. d4 cxd4 4. Nxd4 a6 5. c4 Nf6 6. Nc3 Qc7 7.

{ I only have one chapter for 5. Bd3 not saying it's inferior to the Marcozy and 5. Nc3, but it's less critical. I recommend 5. Bc5 which pushes the knight back to b3. The 5. Bd3 lines are definitely more based on ideas rather than specific move orders. My suggestion is to use opening ideas from the other chapters. Often times, the game can tranpose to a Marcozy Bind with c4, a Hedgehog structure, or just transpose back to the Nc3 lines. } 1. e4 c5 2. Nf3 e6 3. d4 cxd4 4. Nxd4 a6 5. Bd3 { There are several main moves here: Bc5, Nf6, or Qc7. My recommended move is Bc5 mainly because of its flexibility and avoids the sharp lines where white gets an early f4-f5 in. } 5... Bc5 6. Nb3 ( 6. c3 { Harmless setup. Now the knight cannot go to c3 anymore. } 6... d6 7. O-O Nf6 { Black is fine for sure. } ) 6... Be7 7. Qg4 { The main line which provokes g6 to weaken the kingside a little. } 7... g6 8. Qe2 d6 9. O-O Nd7 ( 9... Nf6 $6 { Although seemingly natural, Nf6 is a positional mistake because now Bh6 takes advantage of the weakened dark squares and black can't castle kingside for a while. } ) 10. Nc3 ( 10. c4 { A Maroczy Bind setup is also possible in the Bd3 variation, but it's not as effective because white's Queen, Bishop, and Knight on b3 are not coordinating well together. } 10... Qc7 11. Nc3 h5 { A key move to prevent Bh6! } 12. f4 ( 12. Be3 Ngf6 13. h3 b6 14. f4 h4 { h4 is a common move after both h3 and f4 are played to play Nh5 and head to the weak g3 square, causing even more annoyance for white. } ) 12... Ngf6 ) 10... Qc7 11. f4 ( 11. Bd2 h5 ) 11... Ngf6 12. f5 gxf5 13. exf5 e5 { Although Black cannot castle, usually the king is very safe in the center due to the closed center.
