Are You Afraid of Ghosts?

No? Maybe you should be. Ghosts can cause a great deal of harm, even if they only exist inside your own mind. In chess, ghosts can be a piece, a move, or a sequence of moves. They are ghosts because they aren't real, but you perceive them a real, and also quite scary. Here are two examples:

 This is from an earlier post, Double Delusion. The ghost here is the move Bd6+. It's not real (the Bishop is pinned), Still, the ghost lured Black into playing Rc7, believing that the Rook couldn't be captured because of the Bishop fork on d6. However, the Bishop is still pinned, so the Rook can safely be captured, winning the game. Instead, having reality obscured by the same ghost, White moved his Rook into safety with Rd5, and soon lost the game.

 This one is from a game of my own, played the day after the Double Delusion was published, and appeared in the A Strange Coincidence post. This time, it's the Knight on d5 that will become a ghost, but not until it's captured. This will happen soon if it doesn't leave it's post, being under attack from both Queen and Rook.

The reason that the Knight looks so fearful is the potential fork on e7. This becomes a real threat if the Queen moves away from the e-file, but at the moment, she has nowhere to go. So, White played Re1. Is Black doomed now, since Qxd5 fails to Ne7+, forking King, Queen and Rook? A closer look reveals that the Knight becomes a ghost after Qxd5, and can no longer interact with the real world. Qxd5, and White resigned.

Takeaway

Try not to be intimidated by ghosts. Put them in the spotlight, stare them in the eye, and they will vanish into thin air. It's not the ghosts that are dangerous, it's our fear of them that causes all the damage.

A Strange Coincidence

 The day after I wrote about Double Delusion, it appeared in one of my own games. That might seem like a strange coincidence, but these things happen a lot more often than we think.

N.N. - Me (Open Tournament, 2024)

The Knight on d5 had been a nuisance for a long while. There's a fork on e7, at the moment covered by the Queen. I decided to chase the Night away with 1...Rf5 to free the Queen for other tasks. (That's actually not the best move. 1...Bd4! 2.Nc3 Bxc3 3.bxc3 h4! wins, but that was clearly above my level).

Now, the delusion. 2.Re1?? Black thought that Qxd5 wasn't possible because of Ne7+, forking King, Queen and Rook. Very beautiful, except for the Knight is now off the board, and may no longer participate. Nc7 would have saved the Knight.

My immediate impulse was Qxd5 winning the Knight, but then I saw the fork. Shock and terror! Then I remembered the game Ebralidze - Ragozin I wrote about the day before, and managed to calm down a bit. I forced my to visualise the position after Qxd5 (not too hard to do, being just one move ahead) and realised that there is no longer a fork since the Knight is gone. 

2. Qxd5 and White resigned.

Takeaway

Face your fears! Whenever you're overcome with the "I can't do that" feeling, try to think "I want to do that". Most delusions can be cleared by visualising the position after the move you want to play. It worked for me in this game, and it would have worked in Ebralidze - Ragozin too.

Double Delusion

Can both players make the same mistake at the same time? Yes they can. It happens to grandmasters, and it will happen to you too.

This example is from a classic game, first published in Think Like a Grandmaster by Alexander Kotov, and later in How to Reassess Your Chess by Jeremy Silman (both books are excellent study material for the aspiring club player). Black to move.

 Ebralidze - Ragozin (Tbilisi 1937)

 In this age, Stockfish tells us that this is a draw. Ragozin, however, was clearly troubled by the fact that his Rook and his pawn on a7 are under attack, and his Bishop is pinned. He came up with 1...Rc7, thinking that Rook cannot be captured as 2.Rxc7 Bd6+ wins back the Rook with a winning endgame. The problem is, however, that the Bishop is still pinned, and cannot move. So, White can just take the Rook and win the game.

Alas, Ebralidze had fallen victim to the same delusion, thinking that his Rook, now under threat, must move. 2.Rd5 Bf6 and Black soon won the game.

Takeaway

Lasker said "when you see a good move, look for a better one". That's a good advice, but there's more to it than that. Before looking for a better move, make sure that the good move you've seen really is good. Does it allow a quick mate? Does it hang something? That second look might clear your head of delusions.

Missing the Obvious

This unfortunate mishap comes in different flavours. There might be a piece to be captures, or you've left a piece undefended, or there something devastating one move ahead, all of which you failed to see. This is often referred to as chess blindness, but I find that term misleading. It has nothing to do with poor vision, and blindness seem to imply that there's nothing to do about it. Of course there is! What's happening here is that your mind lures you to focus on something else (using blindfolds as a primary tool). If you allow that, bad things will inevitably happen.

This example starts out as a case of lack of knowledge. 

N.N. - Me (Open Tournament, 2022)

1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5. d4 The Mackenzie Variation. It's an old line, not considered very promising for White. The mail line goes 5...exd4 6.O-O Ne7 with an equal game, but I didn't know that. 5.Nxe4 6.Qe2 This looks strong, but Black has good survival chances in the complications following 6.b5. Instead, I decided to retreat the Knight, completely missing the capture on e5. 

6...Nf6  7.dxe5

Though equal in material, Black is now completely lost. The best move now is 7...Ng8, admitting that the Knight has wasted four moves on absolutely nothing. Instead:

7...Nd5 8.Bb3 Nf4

Finally an active move, hitting both the Queen and g2. However, the capture Bxf4 puts the misfortunate Knight to rest.

That was two times missing the obvious in the course of just eight moves, all because I didn't know the Ruy Lopez well enough. Even if you're unfamiliar with the somewhat obscure Mackenzie Variation, you should be able to play 5...4xd4 on basic principles alone.

Takeaway

There are two lessons to be learned here:

When you go into a Big Think, don't play the move you come up with immediately. Sit back, take a deep breath, and take a fresh look at the position. Are there any obvious captures or threats that you have overlooked?

Also, don't play openings you don't know. There's a choice here - learn them properly, or avoid them altogether.

The Forgotten Task

 When we move a piece to a certain square, we do it because we want it to perform a certain task there. Sometimes it can perform several tasks at the same time, such as controlling an important diagonal and also protecting an important pawn. An ideally placed piece sits on the square from which it can perform the most important tasks. When our opponent has an ideally placed piece, we must immediately try to chase it away, or trade it off.

A common theme, the forgotten task, occurs when we spot a better square for a piece. While exploring what that piece can do on the new square, it's easy to forget what the piece was doing on it's original square. Here's a basic example:

N.N - Me (Swedish League, 2023)

 Black has just played Bb7, threatening Qc7-Qc6-Qxg2 mate. At the moment, though, this is effectively prevented by the strong Knight on d4. So, White is not in immediate danger, the diagonals towards their King are clearly vulnerable. After a long thought, White found a combination that would net him two pawns: 1. Nxe6. Now, 1...fxe6 2.Qxe6 Qf7 3.Qxe5 leads to a sharp position with mutual chances, but the poor Knight completely forgot that it had an all-important task on d4. 1...Qc6 and White resigned, facing an unstoppable mate.

Takeaway

We should always strive to improve the placement of our pieces, but before you do, take a moment to make sure that you're not abandoning some important task.
