“To improve at chess you should in the first instance study the endgame”
Jose Raul Capablanca
This week’s endgame is a beauty! At first glance it looks deceivingly simple. It is white to move; please have a look and guess what the result would be:
Does the position look familiar to you? Do you happen to know more about it? I found it online as is and would love to hear who is the author, plus the time and place when/ where it was published. Moving on, the first thing I noticed were the 4 passed pawns, 2 for each side and on the same side of the board. Both pawns on each side are separated by one file; this means each king has a fighting chance against them. Let’s have a look at how each king has to fight those pesky pawns.
The White king: both pawns are on the 3rd rank and the king is not in their imaginary square (the corners of it are “a1-a3-c3-c1”) to stop their promotion. This means White must use the first move to enter in that imaginary square by playing either Ka4xa3 or Ka4-b3; both moves stop both pawns from promoting. The pawns can’t really do much against any move choice. OK, that sounds reassuring and we can move our attention to the other side.
The Black king: he is in the imaginary square created by the White pawns (the corners of it are “h2-c2-c8-h8). Do you remember why we should consider the c2-c8 as corners instead of b2-b8? Think about it and make sure you find the right answer before moving on. The answer will also be available below for verification. So, should the Black king be worried about those White pawns since it sits comfortably in their imaginary square. Will it just cherry pick them with ease like the White king will do? Apparently it will. Have a look at the White pawns now; could they do anything about it? Well, one strong strategy the pawns separated by a column have in fighting the opposing king is to maintain an L-shape (knight move) formation. They sit on f3 and h2 identical with a knight move and maintaining that makes them intangible. When the Black king attacks the front one (the f3-pawn here), the backwards one (the h2-pawn) moves forward “h2-h4” in the same L-shape (knight move) formation. The Black king would not be able to capture the f3-pawn and also stop the h4-pawn from promoting, so this could pin down the Black King.
Do we have enough to solve the puzzle? Let’s see if we do and will start by taking one of the Nlack pawns (less to worry about, right?):
Hmm, that did not turn out as expected, right? What is the reason for it? Well, the Black king came all the way to the queen side and helped the c3-pawn promote. Fortunately we have the luxury of choosing which Black pawn to take, so let’s try to capture the c3-pawn first. There is no way the Black king can come to the rescue of the a3-pawn:
The answer to the question above regarding the imaginary square of the white pawns: the left hand side corners of it should be c2-c8 because the h2-pawn would move h2-h4 in one move, meaning it could promote in 5 moves instead of 6. You must be aware of this detail with passed pawns still on their original square. Hope you liked it and used this opportunity to refresh your endgame knowledge. If you have any games and/ or positions you would like me to look at, please do not hesitate to let me know. I will gladly include them in my column for everyone’s benefit. Looking forward to your messages!
