Sicilian Vespers

Raymond Keene

rr he Sicilian Defence has made a remark- able able recovery from Capablanca's stern indictment, that it 'leaves Black's position full of holes'. In fact, the recuperation was so spectacular that 1 ... c5 is now generally regarded as Black's most popular method of countering 1 e4. It has proliferated to such an extent that the majority of books currently devoted to 1 e4 c5 concentrate on single complex variations, rather than at- tempting to explain the entire opening.

Two exceptions to this trend are the recently published Sicilian Defence, by Soviet Grandmaster Eduard Gufeld and Beating the Sicilian, by John Nunn (both Batsford, respectively £8.95 and £5.95). Broadly speaking, Gufeld's book is in favour of the Sicilian and forms an ex- cellent basic introduction to the defence. Nunn's book, in sharp contrast, is a slaughterous attack on the Sicilian's viabili- ty. Using 31 illustrative games, in which White scores a massive 30 wins, conceding

only one draw, the author analyses every Sicilian variation, demonstrating a slight, but clear, plus against most lines, while totally demolishing almost all of the rest.

The Dragon, LOwenthal, Nimzowitsch and Maroczy variations come off particularly badly for Black. As far as I can see, the only really healthy way for Black which emerges from Nunn's tract is to play the Scheven- ingen, and this only via the move-order: 1 e4 c5 2 Nf3 e6 3 d4 cxd4 4 Nxd4 Nc6 5 Nc3 d6.

My advice to prospective readers is as follows: if you play 1 e4, buy Nunn's book quickly. If you play the Sicilian yourself, Gufeld's will be very useful to you, but you should be aware of what John Nunn has recommended against your chosen lines, and have something prepared, since your White opponents will probably be burning to try out John's ideas.

Here is one of the illustrative games from Beating the Sicilian.
