BLACK: Christoph Renner



WHITE: Peter Heine Nielsen
Position after 15...Nc6e5

16.Bxc5

• Of course.

16...Qc7 17.Bd4 Nc6?!

• Black is reduced to having two kinds of moves:
  1. Bad; and
  2. Worse.
• If 17...Nxc4? then:
• If 18.Nf7+!! Rxf7 19.Bxf7 e5 20.Bd5 then:
• 20...g5 21.Rb4 Na5 22.Be3 f4 23.Bd2 Be7 24.Ra4 gives White the exchange, but Black has more space.
• 20...Nd6 21.Be3 Bd7 22.c4 Bc6 23.Rd1 Bxd5 24.cxd5 White has a passed pawn and command of the queenside.
• If 18.Bxc4? Qxc4 then:
• 19.Qf4 Qxa2 20.Qc7 Bxd4 21.cxd4 Re8 is equal.
• 19.Qe3!? Kg8 20.Rb2 b6 21.Rd1 Qc6 gives Black a slight edge in space.

18.Bxf6+!

• White cracks Black's center wide open.

18...exf6 19.Nf3!?

• White wins quicker after 19.Qa3 Re8 20.Nf7+ Kg7 21.Rfe1 Rb8 22.Nd6 whne he has the initiative and a huge advantage in space.

19...Re8!?

• The threat to White's e-pawn is too easily paried to take seriously.
• Better is19...Ne5 20.Nd4 Rd8 21.Qh6 Rb8 22.Rfd1 Bd7 23.Qh4 forces Black's King out of his hiding place to protect the hindmost f-pawn.

20.Nd4 Ne5

• If 20...Bd7 21.Nb5 Qe5 22.Qa3 then:
• 22...Be6 23.Qd6 Bxd5 24.cxd5 Na5 25.Rfd1 Red8 26.Qb4 gives the Knight no safe square and forces Black to weaken his queenside by playinng 26...b6.
• If 22...Nd8? then White wins after 23.Nd6! Re7 24.Nxb7 Bc6 25.Na5.
• 20...Nxd4 21.cxd4 Rb8 22.Bf3 g5 23.Qc2 b6 24.c5! leaves Black unable to take the pawn (24...bxc5 25.Rxb8 Qxb8 26.Rb1 Qc7 27.Rb5 c4 28.Rc5).

21.Rd1 Rb8

• If 21...a6 22.Qe3 Rd8 23.Nb3 then:
• If 23...Nc6 then:
• 24.Qc5 Rb8 25.Nd4 Qe7 26.Qb6 leaves Black's position crumbling like ancient ruins.
• 24.Nc5 Na5 25.Bg2 Rf8 26.Nd3 Nxc4 27.Qc5 threatens the Knight.
• If 23...Nxc4? then White wins after 24.Bxc4! Rxd1+ 25.Rxd1 Qxc4 26.Rd8+.

22.Qa3 a6

• 22...b6 23.Nb5 Qe7 24.Qxa7 Qxa7 25.Nxa7 leaves White up by two pawns and winning.

23.c5!

• White's pawns are paralyzed.
• If 23.Qb4 Bd7 24.f4 Nc6 25.Qb6 Rec8 26.c5 Qxb6 27.Rxb6 leaves Black struggling to breathe.

23...Bd7 24.c4 Rec8?

• The threat to take the foremost c-pawn is desperation and nothing else.
• If 24...Bc6 25.f4 Nd7 26.Nxc6 bxc6 27.Rxb8 Nxb8 28.Bf3 gives Black faint hopes of salvation.

BLACK: Christoph Renner



WHITE: Peter Heine Nielsen
Position after 24...Re8c8

25.Ne6!

• White delivers the knockout punch. The center opens up for White heavy pieces while Black's are under constant fire and running for cover.

25...Bxe6 26.Bxe6 Re8

• No better is 26...Rd8 27.Rxd8+ Rxd8 28.Bd5 Rb8 29.Qe3.

27.Rd6 Re7 28.Rbd1 Rbe8 29.Bd5 Nd7 30.c6 bxc6 31.Bxc6

• If 31...Rxe2 32.Bxd7 Re1+ 33.Kg2 then:
• 33...Qxc4 34.Qd3 Qxd3 35.R1xd3 leaves White a piece to the good.
• 33...Rxd1 34.Rxd1 Rg8 35.Qxa6 leaves with up a Bishop.
• Herr Renner resigns.
