the opening ceremony, I was surprised to find out that 'Prague Masters' was a
category 19 event, only one category short of the traditional Tata Masters

idea for White in such position is to play a4-b5, which creates a bind on the

Qc2 {[%mdl 8] Interestingly, as far as I can see, this natural move is
actually a novelty, although the idea is not surprising. We see the point of
white's scheme best in the game continuation around move 16 when he is able to
put his bishop on the most active a3 square straight from home. Basically
white has two principal plans here: 1) To put the queen on b3, play a4 and b5
and generally use the a3-f8 diagonal for his queen's bishop. Black in reply
also has two basic approaches when the move b4-b5 appears  a) to capture on b5,
to some extent opening the queenside, and often after the reply Nxb5 also
ceding the bishop pair, but gaining compensation in the centre, usually in
conjunction with playing ...c5. Resulting hanging pawn positions can be very
tense. b) to reply with ...a6-a5 closing the queenside. This is the part which
creates some tricky questions, with different commentators stating either
explicitly or implicitly quite contrasting views. Some early games with this
structure ( a4,b5,d4 v a5,b6,c7,d5 ) seem to suggest that it is simply bad for
black, and indeed once the bishop on d6 is exchanged the c7 pawn can be very
weak. However, black also has the interesting idea to permit this exchange
only in the context of replying with ...cxd6. Perhaps with the queenside
blocked, black can then find counterplay on the c and e-files? 2) White has
recently shown a tendency to look at simple development of the bishop to b2
and the queen to c2. What then? Well, white can look at ideas of playing a
little in the centre with Ne2-g3 and Ne5, but more often the queenside is
still the focus. White can of course throw in b5 at any stage without the
preparatory a4/Qb3. If then ...axb5 Nxb5 the bishop may be well placed on b2.
And if ...a5? Well, practice suggests that white still does not believe in
alternative plans to good old a4 and Ba3 anyway. This may involve the loss of
one, sometimes two tempi but commentators do not seem unduly concerned ( see
Ivanchuk - Piket from the notes to black's 10th above ). Is this a structure
where planning is all and tempi of little relevance? A look at some of these
ideas in practice:} (11. Qb3 Nbd7 (11... Qe7 12. b5 axb5 (12... a5 {Here is
