There are plenty of puzzle books where you’re invited to find the winning move: to win material or force checkmate. But very few books present puzzles where you have to find the best defence.

Try your hand at this position. It’s Black’s move.

Go away, make yourself a cup of coffee or pour yourself a glass of your favourite tipple, and choose a move before reading on.

I came across this position the other day (I’ll tell you where at some point, but not for a few months). It’s, I think, an excellent defensive puzzle for intermediate standard players.

I set this up on the demo board for the upper intermediate group at Richmond Junior Club (these are young children graded round about 40-70 ECF). They set about analysing the position working mostly in small groups. One of two or them preferred to work alone.

They soon noticed that White was threatening Qxh6, not surprisingly. At this level many children get obsessed with this tactic and sometimes give up the rest of their army in order to set it up. While a few wanted to play a king move to h7 or h8, most of them wanted to move their queen. Some of them spotted that Qf6 lost the exchange to Nd7. I was very impressed that one group at first suggested 1… Qh7, and then explained to me that White could then play 2. Nd7, and if 2.. Rd8, then 3. Nf6+, exploiting the pin on the g-file to play a fork.

Interestingly, most of them failed to mention White’s other threat: Bg4, skewering the queen and rook and winning the exchange. At this level, many players make the mistake of only considering one threat, or one reason for playing a move. Trying to think about more than one thing at once proves to be difficult. This, by the way, is a point that Dan Heisman makes regularly: you should ask yourself “What are my opponent’s threats?” rather than “What is my opponent’s threat?”. Because it’s a more familiar pattern, you will tend to see the threat of Qxh6 before the threat of Bg4.

Once you realise that White has two threats you can start trying to find ways to meet them both at the same time. You might think of 1.. h5, which does meet both threats. Now White can win the h-pawn by playing a fork: 2. Rg5. There’s a stronger alternative, though, in 2. Qh6 Qh7 3. Qd6 with multiple threats: one idea is 3.. Rfd8 4. Nd7 Be6 5. Nf6+ Kh8 6. Qxd8, winning the exchange.

On the other hand, an experienced player would probably sense that 1.. h5 doesn’t look right, so would only consider it if everything else failed. Black has one simple move to meet both threats and leave him with a perfectly satisfactory position. That move, as you’ve probably realised by now, is 1.. Qe6, planning to meet 2. Bg4 with f5. After this move Black is at least equal. Eventually, my students managed to find the right answer for the right reason.

I then wound back the position by half a move. White’s last move was Rg4-g3. I asked the class if this was a mistake. Couldn’t White have played the immediate Qxh6 instead? Doesn’t that move win a pawn? A bright spark quickly provided the information that Black would reply with Qxg4, which will leave him a piece ahead. I’d guess, though, that had they been white in that position, most of them would have played Qxh6 without very much thought. Rg3, by the way, is an unusual way to create two threats. The threat Qxh6 comes about by moving the rook away from the attentions of the black queen, while it’s also a clearance move, vacating a square which the bishop wants to use. I’m not sure that there’s a technical term for this sort of double threat.

When we talk about tactics we tend to think about sacrifices and combinations. Most tactics you’ll find in books (including, at the moment, the CHESS FOR HEROES books) are exactly that. In real life, tactics is mostly about sorting out positions like this, defending accurately, not missing simple one or two movers.
