  Peligroso Patzer: In the generally excellent new book, "Grandmaster Chess Strategy", by Jurgen Kaufeld and Guido Kern, New in Chess ©2011, at page 23, the move <38. h4> is given an “!”, but 38. <Re7!> Is actually stronger because after <38. … Kf6 39. Rxh7>, if Black takes the Knight (<39. … Kxg5?>), he finds his King in a mating net after <40. Rf3>, for example, <40. … Rxc4 41.h4+ Kg4 42. Rff7 Rc2> (otherwise <43. f3#>) <43. Rf4#>.

  Peligroso Patzer: One other interesting subtlety of this game occurs at Black's 36th move. In the game, Nijboer played <36. ... Rc7>. Kaufeld and Kern (op. cit., supra) analyze the alternative <36. ... Re6>, after which their main continuation is <37. Kf3> (probably winning). As an inferior alternative here, they give, <37. Nxc5?! Rxe3 38. fxe3 Nd6> "... and White has major difficulties converting his advantage". (at page 23.)

Interestingly, after <37. Nxc5 Rxe3>, White could probably maintain a decisive advantage with the remarkable <38. Rxe3!> (counterintuitive because it abandons defense of the last Q-side pawn) and then <38. ... Rxc4 39. Nd7!>.

There is no clear and simple set of variations to prove a win in the resulting position (after 39. Nd7):

… but White retains an extra pawn, and the Black pieces are in a terrible bind. It is an ending deserving further analysis (when sufficient time is available).
