So we left you last time considering the Exchange Variation of the Ruy Lopez after the moves 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Bxc6 dxc6 5.O-O. If Black, as he often will in lower level kiddie tournaments, plays a natural developing move such as Nf6 or Bc5 we can capture the pawn on e5 safely, and, if Black tries to get the pawn back we have an array of tactical weapons involving using our rook on the open e-file at our disposal.
The most popular moves, in order of frequency, are f6 and Bg4, followed at a considerable distance, by Qd6 and Bd6. Stronger players tend to prefer f6 and Qd6, while lower rated players are more likely to go for Bg4 or Bd6.
At this level you can usually get away with simple development but there’s one important thing you need to know. It’s a trap which happens quite often in kiddie chess: the Fishing Pole‘s much more respectable cousin.
After 5… Bg4 play continues 6. h3 (a natural move, and by far White’s most popular choice here) 6… h5 when White has to decide whether or not to take the bishop. Theory recommends 7. d3 when both sides have to calculate each move whether or not White can take the bishop. If instead 7. hxg4 hxg4 leaves White in trouble, and if he tries to save his knight with 8. Nxe5 he gets mated after 8… Qh4 9. f4 g3 (the key move, shutting the door on the white king).
Before we move on there’s one other thing you might want to demonstrate, at least to older kids. Look at this variation: 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Bxc6 dxc6 5. d4 exd4 6. Qxd4 Qxd4 7. Nxd4. Now take everything off the board except the kings and pawns and play out the resulting pawn ending. Something like this might happen:
This is worth explaining. White’s winning because he can always force a passed pawn. As long as he doesn’t undouble Black’s c-pawns his opponent will never be able to create a passed pawn. If you run an intermediate level class it’s well worth giving this sort of ending to your pupils. Get them to record their moves and see what happens. In my experience many players will fail to win with White because they play c4xb5 at some point.
This exercise will teach you a lot about doubled pawns: about when and why they can be a disadvantage. It will also teach you a lot about pawn endings. Most importantly, it will teach you how openings and endings are closely connected (even though both are even more closely connected to middle games).
I wouldn’t encourage kids to spend too long playing the exchange variation, though. One reason is that, if you teach them to play the exchange variation after 3… a6 they’ll also make the trade after other third moves, which you probably don’t want them to do. So at some point they’re going to have to move onto 4. Ba4 as well as considering how to meet Black’s most popular 3rd move alternatives.
But first, you might like to demonstrate a couple of famous games. Regular readers will know that I’m very big on teaching chess culture as well as just chess so it’s always a good idea to look at how some of the all-time greats handled the opening you’re learning.
