In the analysis of the game Duras-Capablanca (1913) we saw several positions which are very similar to Levenfish/Smyslov n. 190 (see the thread “Capablanca-Yates, D. 19, the lines a) 7.Rd2 Re3 8.Rh2 fxe6 9.fxe6, and b) 7.Ra4 fxe6 8.fxe6 , as well as the line 7...fxe6 8.fxe6 when Black is to play). Kopayev analysed 1958 once again the position of D. 4 which could have arisen in the line b) 7.Ra4 fxe6 8.fxe6, but he made several mistakes.

**D. 4** **Kopayev 1958, n. 236a** In the line above mentioned line b) 7.Ra4 fxe6 8.fxe6 the White rook was on a4 which does not make any difference.

**1...Rd1+ 2.Ke5 Re1+? ** This move of Kopayev from 1958 throws away the draw. 1956 Kopayev considered the right move 2...Ke7 (Shakhmatny Biulleten, n. 1956, p. 267). After 3.Rc7+ the only saving move is 3…Ke8! 3…Kf8? loses, as shown in D. 1a. After 3…Ke8! Kopayev continued 4.Kf6 Rf1+! 5.Kg6 Rg1! 6.Rc4 Rh1!=.

After 2.Ke5 Black could have drawn also with 2...Ke8=.

**3.Kf6 Rf1+ 4.Kg6 Rh1 5.Rc7 Rg1 ** We have now transposed to Levenfish/Smyslov n. 190, D. 1a after 5.Kf6 Rf1+ 6.Kf6 Rf1+ 4.Kg6 Rh1 5.Rc7 Rg1 6.Kg6 Rg1.

**6.Rf7+? ** We now already that White wins with 6.e7+ .

**6...Ke8 7.Rf4**=.

We have already analysed this position in D. 1a, the line 5.Rh7? after 9.Rf4, and in D. 3a.

**D. 4a** This position is from Kopayevs line a) 7.Rd2 Re3 8.Rh2 fxe6 9.fxe6.

**1...Rd3+! 2.Ke5 Re3+ 3.Kf5 Rf3+ 4.Kg6** 4.Ke4 Rf6 5.Ke5 Ke7=.

**4...Rf4 5.Rh4 ** 5.Rg2 Re4 6.Kf5 Re1 7.Rh2 Rf1+ 8.Kg6 Rf4=.

**5...h5 6.Kxh5 Re4 7.Kg6 Rxe6+ 8.Kh7 Re7+ 9.Kh8 Rg7**=.

We saw in Levenfish/Smyslov n. 190, line 4.Kd7, that Black’s defensive task is easier when his king has access to g7.

**D. 5** **Prizant-Fomin 2000** Without the pawns on g4 and h6 this is the famous Tarrasch-position (1906). Defensive ideas are often similar. The position is drawn whoever is to play first.

**1...Kg6** As in Tarrasch position, every move of the rook along a-file draws as well, except 1…Ra6? In the game

**Smeets-Wiersma (2003) **Black played 1…Ra6? (see the thread „Capablanca-Yates“, D. 22). The game went on 2.Rd6? (2.Ke8+! Kf6 3.e7+-) 2...Ra7+? (2...Ra8!) 3.Ke8 Ra8+ 4.Rd8 Ra7 5.Rd7+ 1–0.

**2.Rd8 Ra7+ ** As in the position of Tarrasch, Black has only 2 saving moves - 2...Ra7+ and 2...Ra6=.

**3.Kd6 Ra6+! ** Again, as in Tarrasch position, the only move to draw.

**4.Ke5 Ra5+ ** Here Black can deviate from Tarrasch position by playing 4...Ra7 but the defence is then more complicated.

4...Ra75.Rg8+ Kh7 6.Rd8 Kg6 7.g5 h5 (or 7...Ra5+ 8.Rd5 Ra1 9.Kd6 Ra6+! 10.Kd7 Ra7+! 11.Ke8 hxg5=) 8.Rg8+ Kh7 9.Rc8 Kg6! 10.Rc1 h4 11.Kd6 Kxg5 12.e7 Rxe7 13.Kxe7 h3=.

**5.Rd5 Ra7 6.Kd6 Ra6+ 7.Ke7 Ra7+ 8.Rd7 Ra8 ** White has made no progress. We are back to the initial position.

**9.Rd8 Ra7+ 10.Kf8 ** **D. 5a** **10…Rh7! ** This is the only drawing move unlike the position of Tarrasch. In the position of Tarrasch Black could play also 10…Kf6 but here it loses because White liquidates to a winning pawn endgame - 10...Kf6? 11.e7! Rxe7 12.Rd6+ Re6 13.Rxe6+ Kxe6 14.Kg7+-.

In the game Sitanggang-Mirumian Black missed 10…Rh7! and played 10…Kg5? After 11.Rd4 Kf6 12.e7 Rxe7 13.Rd6+ Black resigned. White could have also won by 11.e7 Rxe7 12.Kxe7 Kxg4 13.Kf6+-.

1

**) 11.Rd7 Rh8+ 12.Ke7 Ra8!** Draw was agreed. We are again back to the initial position.

12…Ra8! was the only drawing move. As we will see in D. 6 12…Rb8? loses.

In the game

**Hracek-Navara 2004 (rev. col.) **White (Navara) continued stubbornly to play for a win and unexpectedly Hracek made a fatal mistake. After 13.Rb7 Kg7 14.Kd6+ Kf6 15.Kd7 Kg7 16.Ke7 Kg6 17.Rc7 Kg7 18.Rc6 Kg6 19.Rc5 Black went wrong with 19…Kg7? and resigned after 20.g5! Ra7+ 25.Kd8. 19…Ra7+ or any other move with the rook on a-file would have drawn easily.

**2) 11.Ke8 ** This move was played in Shankland-Bao 2008.

**D. 5b** **11…Kg5?** As in previous example this move loses. The only move to draw was 11...Kf6! After 12.Rd6 Black saves the position with 12…Rh8+! 13.Kd7 Ra8 or 13…Rb8.

**12.Rd4? ** White misses the win by 12.Rd7! Rh8+ 13.Ke7 Ra8 (13...Kxg4 14.Rd8+-) 14.Rd8 Ra7+ 15.Kf8 Kxg4 16.e7+-.

**12...Rh8+? ** Again 12...Kf6! would have saved the day.

**13.Kd7.** Black resigned.
