1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 Nc6 5.Nc3 Qc7 6.Be3 a6 7.Be2 One of several significant
moves, but perhaps not the most poisonous. 7.Qf3 could be the most
positional approach: the queen is typically headed for g3, whereupon it will
be exchanged and White will try for a small endgame edge. Black has a few
ambitious options though, including the Nf6 8.0-0-0 Ne5 9.Qg3 b5 10.f4 Neg4 11.Bg1 h5∞ of Karjakin,S-Caruana,F London 2017 7.Qd2 is the only
move I've annotated a game in before: see Radjabov-Rapport, Tata Steel 2019
for 7...b5, Carlsen-Matlakov, Tata Steel 2018 for 7..Nf6 8.f4, or Das-Adhiban,
Reykjavik 2018 for 7...Nf6 8.0-0-0. Having looked at the line fairly
extensively I think 7...b5 is very playable. 7.Bd3 Nf6 8.0-0 Now Black
has a move which is both principled (exploiting the placement of White's
light-squared bishop) and cynical (somewhat simplistic for a Sicilian.) Nxd4!? (There is also ...Ne5, as you would expect.) 9.Bxd4 Bc5 As played by,
for instance, Svidler. 10.Bxc5 10.Be2 d6 11.Qd2 Bxd4 12.Qxd4 e5 13.Qb4 Be6 14.Rad1 Ke7= 10.Bxf6 gxf6 11.Qg4 Qe5∞ 10...Qxc5 11.Na4 11.Kh1 d6 12.f4 Bd7 13.Qd2 Bc6 14.Rae1 Rd8 15.e5 dxe5 16.fxe5 Nd7 17.Qf4 0-0= Vachier Lagrave,M-Svidler,P Riadh 2017 11...Qc7 12.c4 d6 13.Nc3
The question for me is whether White has an advantage in this Maroczy-esque
position. If not, then 8...Nxd4 is simply alright. 7...Nf6 8.0-0 Bb4
Best by test. 8...b5 This is possible, but Black has to continue in a
counter-intuitive way. 9.Nxc6 dxc6 10.f4 Bb7 10...e5 11.fxe5 Qxe5 12.Bf4 Qc5+ 13.Kh1 Be6 14.e5 Nd5 15.Nxd5 Bxd5 16.Bd3 White has a small plus
due to the greater clarity of his plans. 11.e5 Nd5 12.Nxd5 cxd5 We have
now a position that does not inspire great confidence, but in fact to prevent
Black's game from becoming freed White must swap both dark-squared bishops and
queens, leading to a more or less equal endgame, as in the 3.Nc3 Nf6 4.e5
French. 9.Na4 Be7 9...Nxe4 10.Nxc6 Qxc6 10...bxc6 11.Qd4+- 11.Nb6 Rb8 12.Bf3 d5 13.Qd4+- leads to Black getting tied in all kinds of knots:
there could be mate on d8, a Bf4-type motif, or simply carnage after White
takes on g7. 10.c4 This move is known but not especially harmful. 10.Nxc6 bxc6 11.Nb6 Rb8 12.Nxc8 Qxc8 13.Bd4 c5 14.Be5 Rb6 This is the
'tabiya' of the 7.Be2 Taimanov, in which White has generally been able to
prove a little something. 10...Nxe4 11.c5 0-0 12.g3 Nf6 12...e5!?
tries to be better here. 13.Bf3!? 13.Nb3 d5 14.Nb6 Be6 15.Nxd5 Qd7 13.Nf5 d5! Whichever side ends up material down will have compensation
for it, e.g. 14.cxd6 Nxd6 15.Bb6 Qd7 16.Nxe7+ Qxe7 17.Bc5 Rd8 18.Nb6 Rb8 19.Nc4 Nd4 20.Nxd6 Rxd6 13...Nxd4 13...exd4 14.Bf4 d6 15.Bxe4 Be6= 14.Bxe4 d5 15.Bg2 15.Bxd5 Bh3 16.Bxd4 Bxf1 17.Qxf1 exd4 18.Qc4 Rad8 15...Nf5! 16.Nb6 Be6 17.Nxa8 Rxa8 18.b4 Nxe3 19.fxe3 Rd8 13.Nb6 Rb8 14.Rc1 g6 Black is clearly trying to play ...e5, but this will now
take more work than previously. 14...Rd8= followed by the brazen ...e5
and ...d5 was still enough to equalise. 15.Bg5 Rd8 16.Bf3 h6 17.Bxh6 e5 18.Nxc6 18.Nxc8 Qxc8 19.Nxc6 dxc6 20.Qe2= 18...dxc6 19.Qe2 Be6 20.Rfe1 Nd7! Keeping it solid. 21.b4 Nxb6 22.cxb6 Qxb6 23.Qxe5 Qd4 24.Bf4 Qxe5 25.Bxe5 Rbc8 26.Bc3 26.a3 Rd3 27.Rc3= was now the depressing
reality of the position. 26...Rd3 26...Bg5!? 27.Bg4 Bxg4 28.Rxe7 Bf3 29.h3 Rcd8 30.Kh2 R3d7 31.Rce1 Personally, I would have found 31.Rxd7 Rxd7 32.g4 Rd3 33.Bf6 worth trying, if nothing else because the plan
of Bg5-e3 and Kg3 is the only constructive one I can see. 31...f5 32.g4 fxg4 33.Kg3 Rxe7 34.Rxe7 Rd3 35.Re3 Rxe3 36.fxe3 Bd5 37.hxg4 Bxa2 38.Kf4 Kf7 39.Ke5 Ke7 40.Bd4 Bb1 41.g5 Kd7 42.Bb6 A good hold by Black- at some
points he was equalising so well that he might even have been better. ½–½

06.03.2019 – Die beiden englischen Eliteuniversitäten Oxford und Cambridge sind auch beim Schach Rivalen. Am 2. März kam es zum 137. Schachkampf zwischen den beiden Universitäten und Star dieses Duells war Ex-Frauenweltmeisterin Hou Yifan, die zur Zeit als Rhodes Scholar in Oxford studiert. Hou kam nur zu einem Remis, aber ihr Team gewann mit 4,5-3,5. GM Daniel Fernandez, früher selbst Student in Cambridge, berichtet. | Bild: Team Oxford mit Andrew Rogozinski (Ersatz), Daniel Abbas, Hou Yifan, Joris Gerlagh (Kapitän), Benjamin Foo, Lisa Schut, Gordon Scott, Filip Mihov, Isaac Sanders | Foto: John Saunders
