[...] 1.e4 d6 2.d4 ♘f6 3.♘c3 g6 4.♗g5 ♗g7 5.♕d2 c6 6.♗h6 ♗xh6 7.♕xh6 ♕a5 8.♗d3 c5 9.d5 ♘bd7 10.♘f3 b5?! Shaw assesses this move as dubious in his recent book.
10...c4!11.♗xc4 ♕c5!12.♗d3 ♕xf2+ 13.♔xf2 ♘g4+ 14.♔g3 ♘xh6 is what he recommends for Black.
11.O-O c4 12.♗e2 b4 13.♘d1 ♕c5 14.♘g5 ♖b8 15.♘e3 This is Shaw's novelty, improving on Bergamini - Braun, email 2000. 15...♘e5 The key Black piece is the knight on e5. If this is dislodged, then the Black position would fall apart. Both f7 and c4 would become vulnerable. However, the queen on c5 makes this hard, due to the pressure it exerts on the a7-g1 diagonal. Also, the queen can create counterplay by ...Qd4 'with the idea' ...Qxb2 or ...Qd2. 16.h3 White initiates a slow build-up by covering g4 to free his pieces. The idea is Rfe1, Bf1 then either play in the centre with f4 (possibly combined with moving the king out of the pin) or on the queenside with a3. 16...♕d4 17.c3!17...bxc3 18.bxc3 ♕c5
18...♕xc3 is not a good idea, as after 19.♖ac1 White will regain the pawn and the queenside will be opened up. Black cannot afford this as his king is currently stuck in the centre.
19.♖ab1 ♖b6 Black has to play this to keep the queenside sealed. 20.♖fc1 White intends Rb4, intending to liquidate both c-pawns and open the queenside. 20...♘d3 21.♕g7 ♖f8 22.♖d1 ♘f4 23.♗f3! White needs to discourage ...N4h5 by Black.
23.♗f1? allows Black to force a draw by repetition after 23...♖xb1 24.♖xb1 ♘4h5 25.♕h6 ♘g8 26.♕xh7 ♘gf6 27.♕h6 ♘g8
23...♘d3 24.♘xh7 ♘xh7 25.♕xh7 White has won a pawn, but still needs to break open the Black position. 25...♗a6 26.♗e2 ♘f4 27.♗f1 ♘h5 28.♕h6 ♘f6 29.e5! White initiates a forced sequence to open up the position. 29...dxe5 30.♕g5 ♘e4 31.♕xe5 f5 32.♖xb6 axb6 33.♗xc4!33...♗xc4 34.♘xc4 ♕xc4 35.d6 The point - Black has to return the piece. 35...♘xd6 36.♖xd6 ♔f7 37.♖xb6 ♖a8 38.♖b4 White is now two pawns up and has an attack. 38...♕e6 Black could find nother better than going into an endgame. 39.♕xe6+ ♔xe6 40.a4 ♖a6
40...♖c8 41.♖b3 ♖a8 42.♖a3 and White's queenside pawns are securely defended.
41.♔f1 White first brings his king to the centre. 41...♔d6 42.♔e2 ♔c6 43.h4 Now he prepares to create a passed pawn on the kingside as well as the queenside. 43...e5 44.f3 ♔d5 45.g4 ♔e6 46.♔e3 ♔e7 47.gxf5 Black decided to give up now. He cannot cope with both the passed a- and h-pawns.
