Knight Forks and (K)nightmares

Neophyte chess players are sometimes haunted by memories of knight forks.  But even grandmasters find themselves immersed in similar situations.  The game below is a fine example.

New York, 1913
Queen's Gambit Declined

1. d4, d5
2. c4, e6
3. Nc3, Nf6
4. Nf3, Be7
5. Bg5, Nbd7
6. e3, 0-0
7. Rc1, b6

Black intends to follow-up with c5, but the resulting position created a weakness on white squares.

8. cxd5, exd5
9. Qa4, Bb7
10. Ba6, Bxa6
11. Qxa6, c6?

Reinfeld recommends 11....c5 as a more energetic move.

12. 0-0, Ne4
13. Bxe7, Qxe7
14. Qb7!!, Rfc8
15. Nxd5! ....

15. .... Qd6

The Knight could not be taken because of 16. Rxc8 winning a Rook.

16. Rxc6, Resigns

Black loses his Queen if 16....Qxd5, 17. Rxc8 ...  and also if the Queen takes the Rook by 16. .... Qxc6, then 17. Ne7+.

If 16....Rxc6 then 17. Qxa8+ Nf8, 18. Qxc6 Qxc6, 19. Ne7+ and this leaves White ahead in material.  However, in this variation, Black could have prolonged the game a little longer with 17....Nb8, 18. Ne7+ Qxe7, 19. Qxb8 Qf8, 20. Qb7 Re6 (not 20.....Qe8, 21. Ne5!), 21. Rc1 Re8, 22. Ne5 (with the idea of 23. Rc7) f6, 23. Qd5+ and White still wins after 23....Kh8, 24. Nf7+ Kg8, 25. Nd6+ Kh8, 26. Nxe8 Qxe8, 27. Qxe4!.
