**II. 3.f5? ****D. 18****1)** As indicated by Kopayev the best move here is

**3...Kf8.** Kopayev apparently assumed that it is easier to draw with the White king on e4 rather than on d5. So he did not provide for concrete variations and referred to the line 4.Kd5? Kf8! in Duras-Capablanca (col. rev.) where the White king has already advanced to d5. After 3…Kf8 Black can keep his rook on e-file and exchange the central pawn of White if it advances. The ensuing e- and g-pawns versus h-pawn or f- and g-pawns versus h-pawn positions are as a rule drawn.

**2) 3…Rg1?** **Duras-Capablanca (col. rev.). **This move of Duras loses.

**4.Kd5? **Capablanca fails to exploit his opponent’s mistake. Kopayev’s move 4.Rd7! wins here.

a) 4...Kf8 5.f6 Re1+ 6.Kd5 Rd1+ 7.Kc6 Rc1+ 8.Kb5 Rb1+ (8...Ke8 9.Re7+ Kf8 10.Ra7 Ke8 11.Ra8+ Kd7 12.Rf8 Ke6 13.Re8+ Kd5 14.e6) 9.Kc4 Rc1+ 10.Kb4 Rc8 11.Kb5 Re8 12.Kc6 Rxe5 13.Rd8+ Re8 14.Rxe8+ Kxe8+-

b) 4...Rxg4+ 5.Kf3 Rg5 6.Kf4 Kf8 7.f6 Ke8 (7...Kg8 8.Rd8+ Kh7 9.Rf8 Kg6 10.Rg8+ Kh5 11.Rg7) 8.Re7+ Kf8 9.Ra7 Ke8 10.Ra8+ Kd7 11.Rf8 Ke6 12.Re8+ Kd5 13.Re7 Rg8 14.Rd7+ Kc6 15.Rxf7+-

**4...Kf8! **Black activates his king and with accurate defence this position is drawn.

**5.Kd6 Ra1 6.e6 **Kopayev showed that 6.f6 also does not help. 6…Ke8 7.Rb4 Rd1+ 8.Kc5 Rc1+ 9.Kd4 Rd1+ 10.Kc4 (10.Kc3 Re1 11.Rb8+ Kd7 12.Rb7+ Ke6 13.Re7+ Kd5 14.Rxf7 Re3+ 15.Kd2 Rxe5 16.Re7 Re6=) 10...Rc1+ 11.Kd3 Kd7]

**6...Ra6+? **This final mistake seals Black's fate. Kopayev proved very convincingly that Black could have drawn by 6...Re1!

**D. 19**a) 7.Rd2 Re3 8.Rh2 fxe6 9.fxe6 Rd3+ 10.Ke5 Re3+ 11.Kf5 Rf3+ 12.Kg6 (12.Ke4 Rf6 13.Kd5 Ke7) 12...Rf4 13.Rh4 (13.Rg2 Re4 14.Kf5 Re1 15.Rh2 Rf1+ 16.Kg6 Rf4) 13...h5 14.Kxh5 Re4 15.Kg6 Rxe6+ 16.Kh7 Re7+ 17.Kh8 Rg7=.

b) 7.Ra4 fxe6 8.fxe6 Rd1+ 9.Ke5 Ke7 10.Ra7+ Ke8 11.Kf6 Rf1+ 12.Kg6 Rg1 13.Ra4 Rh1=.

c) 7.Kd7 Re2 8.Rd6 Re4! 9.exf7 Kxf7 10.Rg6 Rf4 11.Kd6 h5 12.Ke5 Rxg4=

On the move Black draws by 7...fxe6 8.fxe6 Ke8 (8...Ra1=) 9.Ra4 Rd1+ 10.Ke5 Re1+ 11.Kf6 Rf1+ 12.Kg6 Rh1 13.Ra7 Rg1!=. Just waiting with rook on e-file also draws. Micawber considers the line 7...Re2 8.Rc4 fxe6 9.fxe6 Rd2+ 10.Ke5 Rd1? and evaluates the position as drawn. In fact the last move loses: 11.Kf6 Rf1+ 12.Kg6 Rh1 13.Rc7 Ke8 14.e7 Rh2 15.Kg7 Rh1 16.Rc6+-. Black draws if he plays 10...Ke7 or 10...Ke8 (instead of 10...Rd1?). E. g. 10...Ke7 12.Rc7+ Ke8 13.Kf6 Rf2+ 14.Kg6 Rg2 15.Kh5 Rg1 16.e7 Rg2=.

**14...Kg8 15.Rxh6 Rg2 16.g5 Rg1 17.Kg6.** Duras resigned.

**3) 3…Re1+?!****Nikolic-Ftacnik (1997).** 3…Re1+?! doesn’t lose but it is a superfluous move.

**4.Kd5 ****D. 20**As we saw in Carls-Matisons (D. 17) this position is drawn even White to play but Ftacnik, Emms and Nunn believe that the position is winning for White. Also here the easiest way to draw is 4…Kf8.

**A) 4...Rf1?! 5.Kd6 Ra1?** This is the decisive mistake. 5…Kf8 still draws. After 58.e6 (Micawber 58.Ra4 Rd1+=; 58.Kd7 Re1 59.e6= Transposition to the analysis Duras-Capablanca) 58...Re1we transpose to the analysis of Kopayev in Duras-Capablanca (see 6…Re1! Instead of 6…Ra6+?).

**a) 6.Rc4 Ra8**Black doesn’t have anything better.

6...Rd1+ 59.Ke7 Rd5 60.e6 (Ftacnik). 58...Ra6+ 59.Rc6 Ra4 60.Rc7 (Micawber). 58...Rd1+ 59.Ke7 Rd5 60.e6 (Emms).

**7.Rc7 Ra6+**7...Kf8 8.Kd7 Ra5 9.Rc8+ Kg7 10.f6+ Kh7 11.e6 (Ftacnik).

**8.Ke7 Ra4 **8...Rb6 fails to 9.e6.

8...Ra8 also does not help. 9.e6 (or 9.Rd7 Rb8 10.f6+ Kg6 11.Rd8 Rb7+ 12.Kd6 Kg5 13.Rd7 Rb6+ 14.Kc5 Re6 15.Re7 Ra6 16.Rxf7+-) 9...fxe6 10.Kxe6++-.

**9.e6 fxe6 **9...f6 10.Kd8+ Kg8 11.e7 (Ftacnik).

**10.f6+ Kg6 11.f7 Rf4 12.f8Q Rxf8 13.Kxf8 e5 14.Rc4.** Ftacnik resigned.

**b) 6.Ke7? ****D. 21**The move 6.Ke7 was recommended by Ftacnik and Micawber and played in Smeets-Wiersma (2003) but it throws away the win.

**6...Ra5! **The only move to draw. 6...Re1? (Ftacnik and Micawber ) fails to 7.e6 Re2 8.Rd7+-.

**7.e6 fxe6 8.fxe6**8.Kxe6 Ra6+ 9.Ke7 (9.Rd6 Rxd6+ 10.Kxd6 Kf6 11.Kd5 h5=) 9...Ra7+ 10.Rd7 Rxd7+ 11.Kxd7 Kf6=.

**D. 22****8...Ra7+ **Black can draw also by 8...Ra8 and 8...Ra6=.

**9.Rd7 Ra6? **This move of Wiersma loses. Black could have drawn by nearly every other move on a-file. E. g. 9…Ra4 10.Ke8+ Kf6 11.e7 Ke6=.

**0.Rd6? **10.Ke8+! Kf6 11.e7+- (Micawber).

**10...Ra7+? **White returns the compliment. Black could have drawn by 10...Ra8! preventing the move Ke8.

**11.Ke8 Ra8+ 12.Rd8 Ra7 13.Rd7+ 1–0****B) 4...Ra1?! 5.Kd6 **Now 5…Kf8! transposes to Duras-Capablanca (rev. col.) (D. 18 after 3…Rg1? 4.Kd5? Kf8! 5.Kd6 Ra1).

Instead of 5…Kf8! Ftacnik, Emms and Nunn consider only 5…Ra6+ ? which loses.

**6.Ke7 Ra7+ 7.Rd7 Ra5 **7...Ra8 8.Rb7 Rc8 9.Kd6 +- (Nunn).

**8.e6 fxe6 9.f6++-**.

After this complicated analysis it is not that much difficult to address the doubts of Micawber.

**1)** **D. 23**Micawber wonders how white wins against 71.......Re1+ in the final position of Kopaevs analysis in the long variation after

**65.Rb7 Kg8! 66.Rb3 Kg7 67.Re3 Rb4 68.Re4 Rb1 69.Rd4 Rf1 70.Rd7 Kg7 71.Ke4** (Kopaevs line from 1956/58).

**D. 24**After

**71…Re1+ **White wins by driving the Black rook off the e-file.

**72.Kf3 ****A. 72…Kf8 ****73.Rd4** The win is analogous to the line in Duras-Capablanca (rev. col.), D. 12 after 9…Kf8 10.Ra4.

**73...Ke7 74.Rd6 Rh1 75.Kg2 Rh4 76.Kf3 h5 77.g5 Rh1 78.Ke4 h4 79.Rh6 h3 80.Kf3 h2 81.Kg2+- ****B. 72...Rf1+ 73.Ke3 Rg1 **73...h5 74.g5 h4 75.Ke4 h3 76.Rd2+-.

73...Re1+ 74.Kf2 Re4 75.Kf3 Re1 76.Rd4 Kg7 77.Kf2 Ra1 78.Rd8+- The win is analogous to the line in D. 16 with the White rook on a8.

**74.Rd8+ ****a) 74…Kg7 75.f5 Re1+ **75...Rxg4 76.f6+ Kh7 77.e6+-

**76.Kf4 Rf1+ 77.Kg3 Re1 78.f6+ Kh7 79.Re8+-****b) 74...Kh7 75.Kf3 Rf1+ 76.Ke4 Re1+ ****D. 25****77.Kf5 Kg7 78.Rd7+-**This position can arise also from the initial position (D. 23) if Black tries after 69.Rd4 to keep the White king boxed in by 69…Re1. White answers by 70.Rd7.

In order to prevent e5-e6 Black has now nothing better than to keep his rook on e-file.

**78...Re2 79.Re7 Ra2**Since Black can not hinder e5-e6 he tries to resort to flank checks.

**80.e6 Ra5+ 81.Ke4 Ra4+ 82.Kf3 Ra3+ 83.Kg2 Kf6 84.Rxf7+ Kxe6 85.Rh7+-. ** **D. 26 = D. 23**After

**61.Rb6?! Ra4 62.Kf3 Ra3+ 63.Ke4 Ra4+ 64.Kf5** Micawber suggests pinning the e-pawn by 64…Ra5 or by 64…Rc4 65.Rb7 Rc5.

**64…Rc4 65.Rb7 Rc5 **If 64...Ra5 then 65.Rb4 Ra1 (65...Kf8 66.Ke4 Ra1 67.Rb8+ Kg7 68.f5+-) 66.Ke4+- See below after 67.Ke4.

**66.Rb4 Rc1 **66...Kf8 67.Ke4 Rc1 68.Rb8+ Kg7 69.f5+-.

**67.Ke4 Re1+ **67...Rg1 68.Kf3+- White wins analogous to the line in D. 10 after 3.Ra4 Rg1 4.Kf3.

**68.Kf3 Rf1+ 69.Kg2 Ra1 70.Rb8+-** White wins analogous to the line in D. 15 after 4.Kf3 Rf1+ 5.Kg2 Rb1 6.Ra8.
