"All in one": A crazy Alekhine

by ChessBase
9/22/2022 – In the ChessBase Magazine column "All in one" you can learn everything you need to know about a specific opening variation on the basis of a single, extensively annotated game in order to be able to add it to your repertoire or even try it out directly in practice! In the current CBM #209, for example, the Ukrainian GM Yuriy Kuzubov presents a surprise weapon against the Alekhine Defence. 4.a4 followed by 5.Ra3 - have you ever seen that before? You can find a short version of his analysis here.

Record-breaking rook development

Yuriy Kuzubov provides a complete overview for the variation 1.e4 Nf6 2.e5 Nd5 3.c4 Nb6 4.a4

1.e4 Nf6 2.e5 Nd5 3.c4 Nb6 4.a4!?

An interesting and unusual attempt for White to cause a crisis in the opening. Now Black has 3 ways to defend against the a4–a5 threat.

4...a5 The most logical move.

4...d6 5.a5 N6d7 6.exd6 (6.e6 At first glance this typical sacrifice looks very promising for White but after deep analysis I have concluded that Black is ok here and even can claim some advantage. Anyway, this line could be used as White in blitz or rapid games especially if you are sure that your opponent is not well prepared. 6...fxe6 7.d4 e5!) 6...exd6 (Worse is 6...cxd6 7.d4 g6 8.Nf3 Bg7 9.Be2 0–0 10.0–0 Nc6 11.d5! Nxa5 12.Ra2N Qc7 13.Be3 b6 (13...Nxc4? 14.Qc1 b5 15.b3 and White is slightly better) 14.Na3 a6 15.Nd4 White has more than compensation for the pawn.) 7.d4 Be7 8.Bd3 0–0 9.Ne2 (9.Nf3 seems more natural to me.) 9...d5 10.0–0 (10.c5!? Nc6) 10...dxc4 11.Bxc4 Nf6 12.Nbc3 The position took a familiar shape. Hard to assess if the few "extra" tempos (a4+a5) are good or not for White. The position is playable for both sides.

 4...d5 First of all White can transpose to the line with 4...d6 after 5.exd6 or play more ambitiously! 5.c5 N6d7 6.d4 (In this version 6.e6? looks too optimistic: 6...fxe6 7.d4 e5 and Black is slightly better) 6...e6 7.b4N with the idea after 7...b6 8.a5! to prevent in advance the typical break a7–a5 8...bxc5 9.bxc5 I think White's perspectives - to prepare active play on the kingside - are clearer here, for example 9...Be7 10.Qg4 (10.Ra3!?) 10...g6 11.Nc3 and White is better.

5.Ra3!?

5.c5 This move looks very tempting, but unfortunately it's not optimal. 5...Nd5 6.Nc3 Nb4! (No reason to help White developing with 6...Nxc3 7.dxc3) 7.Bc4 d5 8.cxd6 exd6 9.Qb3 The right way was shown by correspondence chess players in the game 0–1 (61) Skorna,U (2274)-Reichert,T (2364) ICCF email 2019 9...Bf5! 10.Bxf7+ Kd7 11.Nf3 Nd3+ 12.Kf1 Kc8 Now White has big (probably unsolvable) problems with the development

5...d6 Promising for Black seems 5...e6!?N 6.Rg3 Nc6 7.Nc3! (after 7.d4 d6 White cannot hold their pawn center.) 7...d6! (7...Nxe5? 8.c5! Bxc5 9.d4+– Nice trap!) 8.exd6 Bxd6! 9.Rxg7 Hard to believe that white's a1–rook is on g7! IMHO Black can pretend for some advantage after the simple 9...Qf6 10.Rg3 e5 followed by Bf5 or Be6 and then 0–0–0

6.exd6 exd6

he easiest way to equalize. A few games were played at the Titled Tuesday tournament featuring 6...cxd6 7.Rg3 g6 8.h4 h5 9.d4 (9.Bd3?! Maybe not bad for blitz, but absolutely unacceptable for classic or rapid. 9...Bg7) 9...Bg7 10.Nf3 Most probably White has to concentrate all pieces on the kingside and optionally stabilize position in the center with the move d4–d5. Black has to try push d6–d5 or e7–e5 to get a counterplay in the center. The position is very unusual and absolutely unclear!

7.d4 7.Rg3 Now this move does not look as strong as in case of 6...cxd6. 7...d5!N (The game Hauge - Agdestein 2017 continued 7...Bf5!? 8.Nc3 Nc6 9.d4 Nb4 10.Be2 d5 (10...Nc2+?! 11.Kf1 Ha! The rook is not on a1!) 11.c5 Nd7 12.Bg4 (12.Nf3!? g6 13.0–0 Bg7 14.Bg5 I suppose White can claim some advantage.) 12...Qe7+ 13.Nge2 Bxg4 14.Rxg4 Nf6 15.Rg3 Qd7 16.Bf4 Be7 17.Be5 0–0 18.Qd2 Kh8 19.Rxg7 Kxg7 20.Qg5+ Kh8 21.Bxf6+ Bxf6 22.Qxf6+ Kg8 23.Qg5+) 8.cxd5 Nxd5 9.Nf3 Bf5 Looks like Black can easily solve their opening problems.

7...Be7 8.Rg3 0–0 9.Bd3 Re8 10.Nf3! Bf6+! A nice trap awaits Black in the line 10...Bh4+?? 11.Kf1 Bxg3 12.hxg3 f5 (12...h6 13.Bxh6 gxh6 14.Qc1! Qf6 15.Rxh6 Qg7 16.Qf4 N8d7 17.Bh7+ Kf8 18.Qh4+– with the killing threat of Bf5.; 12...g6 13.Ng5 h5 14.Nxf7! Kxf7 15.Bxg6++– with a decisive attack.) 13.Nc3

Variation diagram

followed by g3–g4 with big advantage for White - all their pieces are concentrated on the kingside and there are no black pieces there! (Immediate 13.g4 also gives White a clear advantage.)

11.Kf1 d5 12.c5 N6d7

With decent counterplay for Black.

Conclusion: The idea with 4.a4!? doesn't guarantee real advantage in the Alekhine Defence, but I am sure that this move could be a huge surprise for your opponents, especially in blitz or rapid. Most of the positions are rare and not well explored. It means that your knowledge gained in this article can help you to beat your opponents over the board!
