had.} (32. Qb6 $1 {I was expecting this move during live transmission and was

just winning. It's hard to see what Black can do against a4-a5-a6-a7...}) 32...

1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. e3 {Both Matthew Sadler and Joel Lautier are
noted for their conscientious and deep opening preparation. They also know
each others game particularly well, and are both specialists in the Nimzo with
4.e3. All of these facts render the opening phase of special interest here.}
O-O 5. Bd3 c5 6. Nf3 b6 7. O-O Bb7 8. Na4 {This is regarded as the most
critical line here. White places his knight off-side quite simply to prevent
its exchange, and thus induce one of two effects: i) Black to exchange on d4
in order to open up the natural path of retreat for the bishop on b4 which
will clarify the centre and leave white with a little more space.  Wells: This
is regarded as the most critical line here. White places his knight off-side
quite simply to prevent its exchange, and thus induce one of two effects: i)
Black exchanges on d4 in order to open up the natural path of retreat for the
bishop on b4 which will clarify the centre and leave white with a little more
space.  ii) The bishop on b4 will be forced to retreat to the unnatural square
a5, from where it will play a limited role in the struggle for the centre and
in some cases its very survival may be under threat.} Qe7 $5 {This ambitious
move was played quite often in the 1960s, but was virtually unknown in recent
practice until Boris Gelfand used it to beat Lautier(!) in Bad Godesburg 1997 
( see CBM 58 ).} (8... cxd4 {[%cal Yb4f8] is still the main line. It can be
seen as a 'healthy exchange of diagonals' where black secures his bishop's
retreat, and sets up something akin to a 'hedgehog', while white enjoys the
customary spatial pull. Of course in this case the return of the a4 knight is
only a matter of tempi.} 9. exd4 {[%cal Yc1g5]} (9. a3 $5 Be7 10. exd4 {

black's which will be more sorely missed. Moreover, practice suggests that

supported by g2-g4 with very little real cost in terms of weakening white's
king. Meanwhile it is difficult for black to undertake anything active. 2)
After the exchange on f5, white has 3 v 2 on the king-side, while black has a
passed e-pawn. The former as we shall see, has ( given careful handling )
potential mobility. The e-pawn too, but when advanced, as black shortly does,
it seriously weakens the d6 pawn, and enhances in general the power of white's

desirable ) manouevre of the knight to e5. I suspect that black is already in
some trouble.} 26. Be2 Qc8 27. g4 $1 h5 $6 {This also looks questionable. With
