Rook and Knight endgames – Tactics part 1

Rook and Knight Endgames - Strategy and Tactics book looks at endings with rook + knight Vs. rook + knight. This material balance occurs quite frequently in tournaments, and some classical ideas and endgames have become well-known. Nonetheless, there is some lack of discussion of this topic in chess literature. The book covers both the strategic themes, and gives the reader a chance to practice their tactical skills. Mikhail Botvinnik was well known for his great technique in this type of endings; the book includes several relatively unknown examples from his career to illustrate the typical ideas, but also games by other famous players such as Korchnoi, Morozevich and Anand are featured. Here are some sample tactical positions (scroll down for solutions):

# Solution: 37. Rxg4 Rh2
( 37. ... Rxg4 38. Nf6+ Ke7 39. Nxg4 +- leaves White with two extra pawns. )
38. Ng7+ Ke7 39. Nf5+ Kf6 40. b3 +- a5 41. Rg8 Ke5 42. Rf8 Nd6 43. Nxd6 Kxd6 44. Rf4 b5 45. a3 Ke6 46. Rg4 Ke5 47. Rg6 Rxh4 48. Rxc6 Kd4 49. a4 bxa4 50. Rc4+ Ke3 51. Rxa4 Rh5 52. Kb2 Rg5 53. Rc4 Rh5 54. Ka3 Re5 55. Ka4 Kd2 56. Rc8 Kc1 57. c4 Kb2 58. Rb8 Kc3 59. Rb5 1-0

# Solution: 39. Rc7+! Kxc7 40. Nxe6+ Kd7 41. Nxf4
With the pseudo sacrifice not only has White regained the pawn, but he also achieved a knight endgame, which is winning for him due to the dangerous 'a' pawn, and more active placement of pieces.
41. ... Nc6
( Defending the 'd' pawn allows White to collect both pawns on the kingside. 41. ... Kc6 42. Nxh5 +- )
42. Nxd5 Nxe5+ 43. Ke4 Nc6 44. Nxb6+ Kc7 45. Nd5+ Kd6 46. Nf4
Black resigned as his kingside pawns cannot be defended.
1-0
