EINTALU - ASMUS 1.5-1.5

If I have a bad caprice, then Andres feels more confident, he is not afraid of me and plays nicely.

3. game: Eintalu - Asmus 1-0



This was my only win. The game was not so strong, however.

1. game: Eintalu - Asmus 1/2-1/2


[FEN "r4rk1/1p2bppp/4n3/1qP1p3/1P1pP2P/3P2PB/3BQ1K1/R4R2 w - - 0 1"]


This is an interesting position.

While White was thinking his next move, Andres philosophized about the contest for the open file. Neither player wants to give up the open a-file. Therefore, neither player wants to be the first to leave with one's rook the a-file or exchange it.

I answered that this situation can also be used to seduce the opponent's rook away from the kingside to start an attack on the kingside.

     1.  Ra1xa8    ?!

Here, the truth about the open a-file contest was that Black's Rook on f8 was overladen because it had to defend both the Rook on a8 and the pawn on f7. The right continuation was
1. Rxf7!  Rxa1 2. Rxe7 Nd8 3. Qh5!  +/- threatening with 4. Bf5.

     1...             Rf8xa8      
     2.  Rf1xf7    ??

White decided to prove that it is possible to play against Andres with a missing rook. Better was
2. Bxe6 fxe6 3. Qg4 Qd7 4. h5 Ra2 5. Rf2 +/=

     2...             Kg8xf7      
     3.  Qe2-h5+        g7-g6      
     4.  Qh5xe5      

Not 4. Bxe6+ Kxe6 5. Qxh7 Qe8 or 4. Qxh7+ Ng7 5. Bh6 Bf6.

     4...             Ne6-g7    ??

4... Qd7!  -+



     5.  Qe5-d5+? 

After Black's major mistake at the last move, White had a draw here:
5. Bh6 !! Bf6 6. Qd5+ Kf8 7. Qd6+ =

     5...             Kf7-f8      
     6.  Qd5xd4        Ra8-d8! 
     7.  Qd4-f2+       Kf8-g8      -+

The remaining part of the game is boring, and it demonstrates only how one can sometimes construct all kinds of traps even if the opponent has an extra rook.
And here I said:
"After making the rook sacrifice, White's position is excellent, but only that White's pieces have bad positions."

     8.   d3-d4        Qb5-d3! 
     9.  Bd2-e3        Qd3xe4+     
    10.  Kg2-h2        Rd8-f8      
    11.  Qf2-e1        Rf8-f3      
    12.  Be3-f2        Qe4xe1      
    13.  Bf2xe1        Ng7-f5      
    14.   d4-d5        Rf3-d3      
    15.   d5-d6        Be7-f6      
    16.  Bh3-g2         b7-b6      
    17.   h4-h5        Bf6-e5      
    18.   h5xg6         h7xg6      
    19.  Bg2-e4        Rd3-e3      
    20.   d6-d7        Be5-c7      

20... Re2+!  21. Kh3 Bc7 

    21.  Be4-d5+       Kg8-f8      
    22.   c5xb6        Bc7xb6      
    23.  Be1-f2        Re3-e2      
    24.  Kh2-g1        Re2xf2    ??

24... Bxf2+ 25. Kf1 Nxg3+ 26. Kg2 Ke7 

    25.   d7-d8=Q+     Bb6xd8      
    26.  Kg1xf2      



Now, Black has only an extra piece. Suddenly, Black offered a draw.
Andres did not want to use the chess clocks. But the present game had been painfully lengthy, and we had wasted more than an hour in the coffee. Andres wanted to play some more games. But perhaps he did not remember, how to give checkmate with the Bishop and a Knight  probably White will eventually sacrifice its Bishop for the Black's g-pawn.
Anyway, he was right that I could resist one more hour. As a last resort, one can always check whether the opponent remembers how to checkmate with a King + Bishop + Knight against the King. At least, in the coffee chess.

        1/2-1/2


2. game: Asmus - Eintalu 1-0


[FEN "4rr1k/p2q2bp/1p3np1/2ppB1N1/5P2/2P5/PPQ3PP/4RRK1 w - - 0 1"]



White has a slightly better position.

     1.  Qc2-f2 

Perhaps, stronger was
1. f5 Rxe5 ?! 2. Rxe5 Ne4 3. Rxd5!  Qxd5 4. Qxe4 Qxe4 5. Nxe4 gxf5 6. Nd6 or, better,
1... gxf5 2. Rxf5 Kg8 3. Rf1 Ne4!  4. Rxf8+ Kxf8!

     1...             Kh8-g8    

1... Ne4!

4. c4 g5

     4...             Qd7xg7

     5.  Nf3-e5      



    5...        g6-g5    !?

5... Kh7 =
Unfortunately, White successfully avoided the traps.

     6.  Qh4-h5         g5xf4    

6... Kh7 7. fxg5 Nxg5

     7.  Ne5-g6!

7. Rxf4 ?? Rxe5 8. Rxf8+ Qxf8 9. Qxe5 ?? Qf2+ 10. Kh1 Qxe1 #

7. Ng4 Qg5 8. Nxh6+ Kg7 9. Qxg5+ Nxg5 10. Ng4 =



     7...              f4-f3    ??

7... Rf7 8. Nxf4 Re5 =
As it follows, White avoids all the traps.

     8.  Qh5xd5+  

8. Rxf3?  Rxf3 9. gxf3 Kh7 10. fxe4 Rxe4 

     8...             Qg7-f7    

8... Kh7 ?? 9. Nxf8+ Rxf8 10. Qxe4+ 

8... Rf7 ?? 9. Rxe4 Rxe4 10. Qxe4

     9.  Qd5xf7+  

9. Rxf3  Qxd5 10. Rxf8+ Kg7!  11. Rxe8 Kxg6 12. R8xe4 +/=

     9...             Rf8xf7    

Unfortunately, Black had miscalculated the combination beginning with 7... f3? It was not possible to proceed 9... Kf7 as it was earlier planned:
9... Kxf7?  10. Nxf8 f2+ 11. Rxf2+ Nxf2 12. Rxe8 Kxe8 13. Kxf2 Kxf8 14. Kf3 +-

    10.   g2xf3?

10. Rxf3!  +/-

    10...             Rf7-g7      
    11.   f3xe4        Rg7xg6+     
    12.  Kg1-f2      +/=



After making a wrong combination, in which White did not fall into the traps, Black has some chances to draw the rook endgame with a missing pawn.

Finally, the endgame K + R + P against K + R was on the board, with Black's King on the right place - on White's queening square.

Then, Black suddenly was able to lose that classical "Philidor position".
White's Pawn was on the c-file, making it more difficult to defend after a mistake had been made.


Philidor Position

1... Rg1-g6! makes an easy draw

Neither was Black able to see the variations nor remember the endgame theory - the "6. rank defence". It is meaningless to give checks from the 1. rank, because White's King can hide behind the Pawn c5, suddenly threatening to give checkmate on the 8. rank. Black has to keep one's Rook on the 6. rank, on the longer side, to deter White's King from striking forward. If White moves the Pawn on c6, Black has to immediately move one's Rook on the 1. rank to give the checks. Then, White's King cannot hide behind the Pawn anymore.

Otherwise, this rook ending belongs to higher mathematics. See:

Nunn, J. Secrets of Rook Endings (1999), pp 209-220.

SUMMARY


In the 1. game, 1. Rxa8?! Rxa8 2. Rxf7?? was a major mistake. But after 1. Rxf7! White had a strong attack. This game also illustrates how one can naturally arrive in the situation when one is forced to know how to checkmate with a bishop and a knight.

In the 2. game, the classical Philidor position was finally on the board. It demonstrates both how one can naturally arrive at such a position from a complicated rook endgame, and how important it is to remember the ideas introduced by Philidor in 1777. 

In the 3. game, after 12... Ng4?? 13. Qxg4 d5 Black won the piece back, but White used the time factor to attack the King: 14. f5! dxc4 15. Bh6 with a winning position.
