50 THE BOTVINNIK SEMI-SLAV a) 19 exd8'ii'+ ~xd8 20 ~e2 is Yermolinsky's favourite, when after 20 ... ~c8 21 'ii'c2 "e6, he has tried: a1) 22 ~f41?"g4 23 :fe1.th6 24 .txh6 "f3 (Shabalov claims that Black already has equalized; in his opinion White has to allow a perpetual check) 25 ~f1 'ii'hl+ 26 ~e2 "f3+ 27 ~d2 (27 ~f1 =) 27 ... "xf2+ 28 :e2 'iVd4+ 29 ~c1 .tf31. A fantastic attacking idea; in fact White must now play extremely accurate to maintain the balance; for example: all) 30 j,g7?? :xh2! 31 :xh2 'fig1+ 32 ~d2 'ii'xh2+ 0-1 Ermolinsky-Shabalov, USSR 1986. a12) 30 "d2 is the only move according to Shabalov, though he nevertheless likes Black's position after 30 .. .lhh6 31 'iWxd4 cxd4 32 :d2 d3 33 l:i.f2 .tc6; I am not sure I agree with this. Black needs a reply to 34 b3 and neither 34 ... ~xf6 35 bxc4 ~e4 36 l:i.f1 :xh2 37 ~xd3 ~c3 38 l:i.b2 ~xa2+ 39 ~b1 nor 34 ... c3 35 ~xd3 .te4 (35 ... a5 36 :a1 .te4 37 ~e1 ~c5 is too optimistic) 36 ~xb4 .txb1 37 ~xbl looks adequate. However, I do not see why the bishop has to be on c6. 33 ... ~e5 seems more to the point, when, I think, Black can indeed claim compensation. a13) 30 'iWa4 lhh6 31l:i.e8+ ~b7 32 'iVb5+ ~c7 33 'iVa5+ ~b7 and White does not have better than 34 'iVb5+ with a perpetual check. a2) 22 f3! .td6 23 :bd 1 and now: a21) 23 ... .te5 24 :f2 (24 'iVa4!?) 24 ... l:.gX 25 ~f4 'ii'c6 26 ~d5 +- Yermolinsky-Lapshun, Philadelphia 1998. a22) 23 ....tc6 24 ~f4 'iVe3+ 25 'fif2 'iVxf2+ 26 l:i.xf2 .te5 27 ~d5 (27 ~g2 might be preferable) and now rather than 27 ....td4? (Ermolinsky Makarov, USSR 1986), which gives White a clear advantage after 28l:hd4! cxd4 29 ~xb4, Black should play 27 ....txd5! 28 l:i.xd5 .td4 with equal chances - Makarov. b) 19 ~d5!? (D) and then: B b1) 19 ... 'fie6!?20exf81r' l:.dxf8 21 ~e7+ ~d8 22 f3 l:.h5 23 'fid2 l:.fh8 (Uhlmann-Schon, Porz 1990) and now 24 l:i.be1 'iVh3 25 l:i.e2 is the easiest. Black's attack looks well neutralized. b2) 19 ... 'fib7!? (this is the point of retreating the bishop all the way to a8) 20 exf8'iV l:.hxf8 21 ~e7+ ~c7 22 .tf4+ ~e5 23 .txe5+ ~b6. Shabalov initially assessed this as winning for Black in view of the forced win of White's queen, but as Santos soon pointed out, this is actually far from clear. He suggested that White has
