Tactics: Leaving Reykjavik in Style

This week's Canadian Tactic comes from the last round of the 2014 Reykjavik Open. Daniel Kazmaier is White against a Women's GM and has sacrificed a N to expose the Black King. White's immediate threat is Nc5+ winning the Nc6. 

What should Black play?

Hint: consider these three moves:

25...Nc4 
25...Rfc8
25...Nxd4

 

 

Not this one...

Black can concede that she can't save the Nc6 and try to get something for it, but ...Nxd4 doesn't save the game or her King:

25...Nxd4 26.Nc5+ Ke8  27.Rxd4!  (27.Qxd6 +-)  27...Qxd4  28.Qc6+ Kf7  29.Qd7+ Kf6  30.Rxe6+ Kf5  31.Rxd6+ Be6  32.Qxe6#.

25...Nc4 Best, but Black's position is still bad.  26.Nc5+ Kd6  27.Ne4+!

 27.Nb7+ Kd7  28.Nc5+ repeats.

 27... dxe4  28.Qc5+ Kd7 (or Kc7) 29.Bxe4 +/- White wins one of the the Ns and has three pawns for the piece and a continuing initiative.

  

 

The game concluded:

25...Rfc8?  26.Bxd5! +- 

If Black takes the B then her King can't use the d-file, and 27.Nc5#.

 26.Nc5+ is not as convincing: 26... Ke7  27.Bxd5 Rab8  28.Qa6 Ra8  29.Qd3 Nb4  30.Qb3 with a continuing attack.

 

26...Qd8  27.Bxc6+ Rxc6  28.Nc5+ (only move) Rxc5  29.Qxd8+!

1-0

 After 29.Qxd8+ Rxd8  30.dxc5 White will soon be up an exchange and two pawns.
