200 THE BOTVINNIK SEMI-SLAV 12a4 12 l:r.c 1 is also very common and often arises from the move-order 11 l:r.c1 0-012 b4. Now Black has a choice: a) 12 ... b6 13 bS!? cS (13 ... .i.b7 !?) 14lLle4 (14 dSlLleS ISlLlxeS 'ii'xeS is fine for Black) 14 ... 'ii'e7 IS dxcslLlxcs 16 lLlxcs bxcS (16 ...

Black has a reasonably clear-cut plan, viz. to complete his development and then prepare to play ... cS or ... eS; if White follows with a4 at some point then Black replies ... as. By contrast, White's best plan is not at all clear. The most logical is to continue some sort of queens ide action but Black seems well placed to meet this; the other possibility is to switch to playing in the centre: c21) 14 bS .i.b7 IS bxc6 .i.xc6 16 .i.e2 (16 lLld2 a6 17 .i.d3 bS 18 .i.e4 .i.xe4 19lLlcxe4lLlb6 20 l:r.c6 'ilb7 21 l:r.c2 'ii'dS 22l:r.fc1 'ii'xb3 23lLlxb3lLldS = P.Nikolic-Anand, Monaco Amber rpd 1998) 16 ..
