Alekine’s Defence, Haakert Variation with 16…g4 and a New Method of Attack involving 18. c5.
Introduction:
The Haakert Variation was previously discussed in the October 2009 Chess
Publishing Post 1.e4. The variation involving 16…g4 was mentioned.
Some relevant comments have been put forward in this article. An attack involving
18.c5 has been proposed by the author and black is presented
with a different set of problems, which include monitoring of the pawn structure if white
chooses to quickly enter into an end game situation. Black is sound in the middle game
and may need to utilize the g file and the 5th rank in order to adequately counter white’s
build up through the centre.

15.Qe3 g5 16.h6 g4 Such an expansion of the king side was suggested by Juergen Fleck's article in
Kaissiber 19. The black light square bishop has a stable outpost at f5 or g6 and it
cannot be harassed by advancing white king side pawns. [16...Rf4 was suggested
by Buecker in the above mentioned Oct 09
1. e4....updates. After 17.c5 Nc4, Watson mentions 18.Qc1!. Black desperately needs
an improvement to the text and I can’t find one. A strong continuation for white is
18… dxc5 19.Ne2 Qe7 20.Nxf4 exf4+ 21.Be2 Nd6 22.Qxc5 Bd7 23.Kf1 Re8
24.Bd3 g4 25.Qc3! Black is the exchange down and the white queen dominates the
long diagonal. The black queen has limited attacking power due to the committed guarding
of the g7 square. White can casually progress on the queen side while black is committed
to advancing the king side pawns. When black’s attack becomes too threatening, white
can bail out and force the exchange of queens and attain a winning end game position.

17.Be2 Suggested by Raj
Tischbierek.
17...Bf5 18.c5! The g4 pawn cannot be easily rounded up by white
eg. 18.Qg3 Qg5 19.Rh4 Kh8 20.c5 Nd7 21.cxd6 cxd8 22.Bxg4 Rg8 23.Bxf5 Qxf5
24.Qh3 Qxh3 25. Rxh3 Rxg2 = This multidimensional approach 18.c5 forces 18….dxc5,
which leaves black’s centre in temporary disarray and weakens the e5 pawn. The white
d pawn is unblocked and it becomes a passed pawn threat, while white can attack on the
king side.

My proposed improvement over the Watson text. The knight
seems to have galloped and almost stumbled out of the board, but in fact this
curious manoeuvre enables the centralizing Nc5 option and prevents white
from conveniently castling queenside, with 25. O-O-O due to d3! =/Ŧ, which springs
an undiscovered attack on the unsuspecting b2 pawn and unexpected check on the
king. Eg. 26. Rxd3 Qxb2+ 27.Kd1 Kh7 28.Qe7+ Kh6 29.Bxg4 Qxf2 30.Re3 Rf8 =/Ŧ .
The pedestrian 25 b3? also runs into 25…. d3 and white’s queen rook is under
attack. White has two good continuations. 25.Bxg4 [25.Qxg4 Re8 26.Rd1 Nxb2

is that! The knight makes an entrance from positional obscurity, fends off Be6+, attack
the white queen and sets up d3!

25.0–0–0 Qg5+ 26.Kb1 Qf5 Black's position may be okay.]
18...dxc5 19.Rh5 Of course white could try the direct raid through the centre approach, but black is in
a good position to counter this strategy. Eg. 19.Qxe5 Rf7 20.Rh5 Qf6

25.0–0–0 ! The low risk approach. [25.Ne4 The knight move is
more flashy and there is interesting play. Objectively castling queenside is slightly
better. 25…Qg6 26.Nxc5 Nd7 27.Qf3 Nf6 28.Nxb7 Qxh6 29.d6 ! (29.Nd8 Kg8

29...Rg7 30.b3 (30.Rd1 e4 31.Qf5 e3
Black attempts to undermine the white g3 pawn and unleash the patient black rook.
White is beginning to feel the downside of an exposed centralized king in a middle
game situation.

Black can now take advantage of white’s underdeveloped rook and exposed king in
the centre.

26.Qe2 Rd4 [26...Qxh6+ ? 27.f4 +- Black is unable to defend both the rook and knight.]
27.Rxd4 Black has achieved a key positional objective. White must think of a way
to exchange rooks without improving black’s pawn structure.

to save the isolated e5 pawn.
Avoiding the exchange is unfavourable for black, ie 32...Nb6 33.Rxe5 Kxh6 The white
rook is very domineering because it also restricts the movements of the black
knight. 34.Kc2 a5 35.f4 c4 36.Nb5 Rxd5 37.Nxc7 cxb3+ 38.axb3 Rxe5 39.fxe5 Kg5

37.Nxb7 c4 38.Nd6 cxb3 39.axb3 White has a slight advantage, due to the
connected kingside pawns. Black should be able to defend the position.]
27...cxd4 Black was able to undouble the c pawns, but the “rehabilitated” d pawn
is now forced to recapture the c3 knight.
28.Qxc4 Qxh6+ 29.Kc2 dxc3
30.bxc3 Qd6 Equal material, but white's pawn at d5 is a problem. The position should be defendable
for black, who must decide how to build his fortress, prepare against a queen
exchange, optimize the position of the queen and king, and decide how to best protect
the isolated e pawn. Black should not underrate the three connected queen side
pawns and at the right moment an a6, b6, c7 pawn set up will be effective.

The variations involving 16…g4 seems to be solid and dynamic against continuations involving
18.Rh5. The improvement 24… Na4! further consolidates
the robustness of this line.
An attack involving 18.c5 has been proposed and it provides black with a
different set of challenges.
White can pursue a relatively safe approach, which is centered on 25.
O-O-O, but the middle game has less pitfalls for black. The alternative 25.Ne4,
provides very exciting prospects for both sides. Independent of what white plays,
the second player is able to respond with a sound end game situation.
