They are here at last, Whoopee! I’ll be cruising Carlsen like in my neighbour
looking cool as I shoot a few hoops. (that’s Basketball for you uncool nerds.)

The first correct answer gets the left shoe.
The second correct answer gets a right shoe.
The third correct answer gets a left shoe.
You are no doubt thinking that I’ve stolen the single display shoe from
the display rack at three different outlets. You guessed wrong because;
Three puzzles for you to solve. The first ‘hidden’ is a clue.
In this position with White to play. Ding Lien has just played 11...g5.

Giri played 12.Nxg5 and set about working against the pinned Knight on f6.
This is a relatively common Knight for two pawns and pressure sacrifice. The first
time I can find it being played was in the Labourdonnais - McDonnell match in 1834.
Ding knew he was entering risky territory playing 11...g5 (he took 10 minutes) Giri took
4 minutes before playing 12. Nxg4 but he had no choice. 12.Bg3 leads to a poor position.
Before looking at the Anish Giri-Ding Liren game lets us look at some ground rules
The critical pattern. The Basic Attacking and Defending Ideas.

The most common ways of piling on the pressure on the pinned
f6 Knight are Qf3. Nd5 and f4 with e5 hitting the pinned Knight.
This f2-f4 idea can be combined with a Rook on f1 taking on e5.
Black’s most common defensive ideas are Kg7 (mainly against Qf3)
Be7 If Black can break the pin this way then it is difficult for White.
Stop Nd5 by either taking on d5 or c6. Qe7 with Qe6 breaking the pin.
Look out for a Black Queen check to break the pin (after f4 by White.)
If there is a Knight on c6 it can drop back to b8 and reappear on d7.

The e2 Bishop is stopping Qf3. The move f4 cannot be played. The only way to put
pressure on the pinned f6 Knight is Nd5. Black played d6 and after Nd5 it was 1-0.
Let us see how it could have been defended and a plausible what happens next.

Seeing the two major threats Nd5 and Qf3 Black only stopped just one and they
played Kg7 to take the sting out of Qf3 but after Nd5 it was 1-0 a few moves later.
Let’s try defending it. If I get what I think is an unclear position in these situations
I always go for the sac, so should you. The attackers moves are the easiest to find.
