Grumpy Old Farts Playing Chess in Armenia


Pic Note

Looks like a pleasant park to play chess on a Saturday afternoon, doesn't it? The chess set in the foreground looks like it's been used a few times. And the guy on the right looks like the grouchy old geezer who ran the D.A.'s office in the early Law & Order episodes.

Anyway, it's from an article on chess in Armenia that CBD sent my way. Armenia has more grandmasters per capita than any other country.

Since 2011, all children in Armenia from six to eight years old have compulsory chess lessons. It's the first country in the world to include it on the national curriculum.

Now if we could only replace Common Core math with chess, we might actually see an improvement in math scores.

As always, the chess/dress thread is an open thread, so it is impossible to go OT in the comments.


Easier Problem - White To Play (Bain 36)

Black's in a bad way: he's down material and he's in a bit of a jam on the back rank. How does White press his advantage and win?

Hint: Be careful that the rook you capture is the correct one.

More Challenging Problem - Black To Play (WCSC 254)

The problem here is one I got out of one of my books, one by Fred Reinfeld, where you are given a position and told to find the best move for White (or, as in this case, Black). Oh, and also, this problems is in the "double attack" chapter, so the solution is going to take that form.

Hint: Black wins a piece... or does he?

Easier Problem - White To Play

20180224 - Problem 1.jpg
5rk1/4Qppp/3R4/8/8/6P1/5PKP/8 w - - 0 2

1.Qxe7 Rf8!

Black still loses, but the 'book' line loses even more quickly: 1...Rxe7 2.Rd8+ Re8 3.Rxe8#

After 1...Rf8, there are many ways White can win. As rickl said, Black can run, but he'll only die tired:

2.Rd8 h5
3.Qxf8+ Kh7
4.Qxf7 Kh6
5.Rd6+ Kh7
6.Rg6 h4
7.Qxg7#

Answer:

This is one of those problems where the book solution is either simply wrong, or, in this case, inadequate. Reinfeld's solution in its entirety is "1... Bc6 wins a piece." I think he means something like 1...Bc5 2.Rg1 Nxb7, but it's not that simple. White doesn't have to go down without a fight.

1... Bc6
2.Bc3! Bxh1
3.f3

Not 3.Bxe5 because of 3...Bxb7 and White really is down a piece.

3...f6
4.Kf2

The bishop on h1 is toast.

4...Rab8
5.e4 Rxb7

If 5.Na5 then 5...Rhc8!

6.Bxa6 Rb6
7.Be2 Bxf3
8.Bxf3 Nxf3
9.Kxf3

So after the dust settles, we see that White has won the exchange, but not a piece. White is up in material, but whether he can squeeze out a win, and how, is not obvious.

This line appears to have been completely overlooked by Reinfeld. In fact, the solutions to pretty much every problem in this particular book of his break down when I run them through my chess app, which always finds a better continuation.


Hope to see you all next week!.

Note: that cryptic line of letters and numbers you see underneath each board diagram is a representation of the position in what is known as "Forsyth-Edwards Notation", or F.E.N. It's actually readable by humans. Most computer applications nowadays can read FEN, so those of you who may want to study the position, you can copy the line of FEN and paste into your chess app and it should automatically recreate the position on its display board. Or, Windows users can just "triple click" on it and the entire line will be highlighted so you can copy and past it into your chess app.
