The Power of Pawn – Pawn Promotions

In this brief article we will go over some situations where you can end up in pawn ending game. Pawn ending games are always the trickiest part for beginners as they always end up playing it wrong.One important tip to remember when in a pawn ending game is that the King should be in front of his pawn, with at least one intervening square.

(Example 1)

example1

Pawn Promotion – 1 pawn vs 0 pawn

One of the most important endgame position, the whole sequence of moves are important and you must familiarize yourself with the procedure. The reason behind learning the position really well is that, this principle will help you learn the more advance variations of such position. Every beginner should study this position until they can play the moves without any trouble.  I cannot stress enough how important is the given position. As mentioned earlier for any such endgame to be won the king must be in front of the pawn, in this example the game is drawn because white king is not in front of the pawn with at least one intervening square and thus there is no way that white can promote the pawn.

(Example 2)

example2

Pawn Promotion – 1 pawn vs 0 pawn cont.

In this position white is winning given it knows what to do. The strategy to follow is not that difficult the idea is to move the king as far as is compatible with the safety of the pawn and never to advance the pawn until it is essential to its own safety.

The ending is similar to the last one, but in this one white wins and you must study the position thoroughly and practice it as many times as possible to master the sequence of moves because the position can arrive on any side of the board and in many different manners. Thus it is essential to master the moves and then try to over the moves every now and then until the idea is grasped and digested.

A simple sequence of moves to win the position would be as follows -

1.Ke4   Ke6
2.e3     Kf6
3.Kd5  Kf5
4.e4+   Kf6
5.Kd6  Kf7
6.e5      Ke8
7.Ke6

Now no matter where black moves white can secure either f7 or d7 and then promote the pawn to a queen.

(Example 3)

example3

Pawn Promotion – 2 pawns vs 1 pawn

Now we shall move to some more pawn endings these will be bit advanced and thus will require more time to digest than the first ones, but the idea remains the same. Best way to learn these methods would be to practice and practice, this article can only guide you and the rest should be done through practice.

From the diagram above at first glance it may seem easy but these situations can be very daunting to new players and most games can end up in a draw. For example in the given position the best way for white would be to play the following moves -

1.Kd7   Kg8
2.Ke7   Kh8
3.f6       gxf6
4.Kf7    f5
5.g7+    Kh7
6.g8Q+ Kh6
7.Qg6#

As you can see at first glance it may look difficult but with practice it can become a lot more easier, you just remember the basic ideas. In this case we know that king has to be cornered and then give up the pawn in order to push the g pawn and then promote it to queen and then mate is followed. Again you must practice the position good number of times so that you know it inside out and can apply the moves in a real game.

Lets look at another position which can also be very easy but can be very daunting to some beginners and most of them do make mistakes when they end up in a position as such.

(Example 4)

example4

In the following position white cannot win if he/she plays f5 because then black will play g6 and then the game is a dull draw. Same goes for g5 because then again black will move g6 and it is a draw. In this position the best move is Ke4 and then black plays Ke6 you may be wondering why not g6, well if black plays g6 then (kd4 Ke6 Kc5 Kf6 Kd6 Kf7 g5 Kg7 Ke7 Kg8 Kf6 Kh7 and Kf7 wins the pawn) and that is why Ke6 is a better move.

After Ke4 Ke6, the next best move for white is f5+ Kf6 and then Kf4 g6 and after that a series of moves such as 1.g5+ Kf7 2.f6 Ke6 3.Ke4 Kf7 4.Ke5 Kf8 and now white has to give the f pawn in order to get into a position so that the win can come by easily in this case by giving the f pawn white forces the king to capture it and then corner it and win the g pawn and queen its own g pawn. The moves are as followed after Kf8.

1. f7       Kxf7
2. Kd6 Kf8
3. Ke6  Kg7
4. Ke7  Kg8
5. Kf6    Kh7
6. Kf7    Kh8
7. Kxg6 Kg8
8. Kh6    Kh8
9. g6        Kg8
10. g7       Kf7
11. Kh7

And now white will promote the pawn to queen and the mate to follow.

(Example 5)

example5

Pawn Promotion – 3 pawns vs 2 pawns

In this position white can either move f5 or h5 or Ke4. But a simple procedure would be as follows.

1.f5      Ke7
2.Ke5 Kf7
3.g5     Ke7
4.h5     g6
5.hxg6 hxg6
6.f6+

In this position if g6 or f6 is played earlier then one of the earlier positions will come into play by now you should have good idea of some basic positions if you learn the basics then the it will be easier to grasp the other one as well.

(Example 6)

example6

Pawn Promotion – 3 pawns vs 2 pawns Contd

After doing some basics lets move to some other variations of the same positions with pawns vs pawns ending. This time around with pawns on other sides of the board. In a situation like such the general rule of thumb is that you must move your king to the side of the board where you have stronger forces in other words where you have more pawns. But as mentioned before if played incorrectly this winning position can turn into a draw.

Combination of moves to win the game would be the following. Remember the basic idea you move on the side of the board with stronger forces. And then once the king is pushed you can move the king to other side of the board and then win.

1.g4  a5
2.a4  Kf6 (in this position after black has played a5 it is best to move a4 just in case things go wrong the other side you will have the pawn already half way through to move.)
3.h4  Ke6
4.g5   Kf7
5.Kf5 Kg7
6.h5   Kf7
7.Ke5 Kg8
8.g6     h6
9.Kd5  Kg7

Now no matter what white wins so the white king can move to the left side of the board and capture the a pawn if the black king tries to capture white h pawn then the g pawn will move and there is no way to stop it. In this position things can get nasty so always make sure that you have control on one side of the board before moving to the other side.

Chess Endgame Tactics: Rook and Pawn endings – Part 4

You have already seen the established chess tactics for a well-known Rook and Pawn ending called Lucena Position. Here we discuss about Philidor position, another equally well-known chess ending with Rook and Pawn that gives a draw to the defending player if he plays actively and with precision.

Philidor position in Rook and Pawn ending

The requirements for this position are:

  • The pawn of the attacking side and its King have not crossed their 5th rank. The King is in contact with the Pawn
  • The defendant King is on the promotion square or on a square adjacent to it
  • The defendant Rook is on the 6th rank (its own 3rd rank) preventing the enemy King from going forward

The Pawn may be on any file. But as you know from earlier discussions on Rook and Pawn endings, Pawn on Rook file makes the defending King’s job easier.

The position of the Rook of the attacking side (the side having the Pawn) is not directly relevant except for its ability to come to the help of the King and Pawn when necessary. But it is in the interest of the attacking side not to allow the defending King to come forward and create complications. The Rook positioned on the 7th rank keeps the defending King confined to its base rank.

However, check by the attacking Rook does not help in any way as the defending King keeps shuttling between the queening square and the square in front.

The defending side’s strategy:

So long as the Pawn does not move to its 6th rank, the defendant Rook keeps shuttling on that rank (which is its 3rd rank). If the Pawn moves to the 6th rank, the defendant Rook should go to its 7th or 8th rank and keep giving check from behind. There is no respite from check as the attacking King cannot take shelter behind the Pawn.

If the attacking side’s Rook tries to interpose, the defendant should exchange the Rooks. Since defendant King is already in front of the Pawn, all it has to do is to maintain opposition to enemy King, and the ending is a draw.

You can see that if the defending side plays passively and allows the enemy King to get to the square in front of its Pawn and the defending Rook is unable to deliver check, it will be a win for the attacking side. So the defending player has to remain alert if he has to get a drawn game.

A possible sequence of moves in the diagram position is shown below.

Without exchange of Rook:

1. Rg7 Rb6  
2. Rh7 Rg6  
3. d6 Rg1   As the White Pawn has advanced, White K cannot any more take shelter behind the Pawn, so it is safe to move the Black R. If it were done earlier, White would have played Kd6 with a win.
4. Ke6 Re1+  
5. Kd5 Rd1+  
6. Ke5 Re1+  
7. Kd4 Rd1+  
8. Ke5 Re1+   and so on without any headway

 

With exchange of Rook:

1. Rg7 Rb6  
2. Rh7 Rg6  
3. Rf7 Rb6  
4. Rf6 Rxf6   If Black avoids exchange, White K gets access to d6
5. Kxf6 Kd7  
6. Ke5 Ke7   Black must retain opposition to prevent White King’s access to d6
7. Kd4 Kd8  
8. Kc5 Kc7  
9. d6+ Kd8  
10. Kc6 Kc8  
11. d7+ Kd8  
12. Kd6   drawn due stalemate

 

Chess Endgame Tactics: Handling Rook and Pawn endings

We have discussed at length about basic chess endings with Rook and Pawn as also some special techniques for handling a few typical situations. We also said that with Rooks present, a majority of one or two pawns often do not yield much benefit and such chess endgames are more likely to result in a draw, especially if the pawns are on the same side with their Kings close at hand.

But that is only a general observation. In this article we go through the lengthy process of playing through such a situation where White thought that exact play could give him a win with his single pawn majority if he could get a passed and protected KP.

Rook and Pawn ending with multiple pawns

At first sight, there does not seem to be much prospect of a win for White, so let us see what exactly was in his mind! We can of course see that White King cannot advance now without losing the BP.

1. Rb6 Ra2   White’s move blocked Black King’s support to his KBP.
 
2. Rd6 Rb2   Black is shuttling his Rook on rank 2 as ‘wait and watch’ policy while preventing White King from moving forward
 
3. Kg2 Ra2   3. Kg3 f4+ 4. Kxf4 Rxf2+ loses a pawn for White or 3. Kg3 f4+ 4. exf4 doubles the pawns effectively giving White BP and RP against Black’s RP which is a technical draw
4. h4 Ra4  
5. Rd4 Ra6   Other options are worse for Black e.g.,
5. … Ra2 6. Kg3 Kf6 7. Rb4 Ke5 8. Rb7 f4+ 9. Kf3
or
5. … Ra2 6. Kg3 Re2 7. Rb4 Kf6 8. Rb6+ Kf7 9. h5 Kg7 10. Rb7+ Kh6 11. Rf7 Kg5 12. f4+ Kh6 13. Kf3 wins as Black K is out of position and both Black R and BP are en prise
6. Kg3 Kf6  
7. Kf4 h6  
8. h5 Rb6  
9. f3 Ra6   Black R cannot leave rank 6 for fear of check by White R
10. Rb4 Rc6  
11. Rb7 Rc4+   White was threatening 12. Rh7 followed by 13. Rxh6
12. e4 fxe4  
13. fxe4 Rc5   Whie has got his passed KP. Black could possibly try Rc1 here instead of waiting till move 16
14. Rb6+ Kg7  
15. Rg6+ Kh7   Black’s only move to save his RP. If White had a passed KBP rather than KP, Black could have saved the game.
16. e5 Rc1  
17. e6 Rh1  
18. Rg3 Rh4+   18. … Rxh5 19. e7 wins for White
18. … Re1 19. Re3 Rf1+ 20. Ke5 Rf8 21. e7 Re8 22. Ke6 Kg1 23. Kd7 Kf7 24. Rf3+ followed by 25. Kxe8
19. Rg4 Rh1  
20. Kf5 Rxh5+  
21. Kf6 Rh1  
22. e7 Re1   22. … Rf1+ 23. Ke5 Re1+ 24. Re4
23. Rg7+ Kh8  
24. Rf7 Rf1+  
25. Kg6   Black is helpless.
25. … Rg1+ 26. Kh5 Rg8 27. Rf8 Kg7 28. Rxg8+ Kxg8 29. e8=Q+
Alternatively, Black R can continue giving check while the White K keep moving in zig-zag fashion between g-file and h-file till it reaches rank 2 (g6-h5-g4-h3-g2) after which Black runs out of check and White KP gets promoted.
