Exeter Chess Club: Clock control for club players

Or, The Thirty-Third Piece

A. Introduction

Chess is played not with 32 pieces, but 33: the handling of the extra piece, the clock, sometimes being the deciding factor.

Time trouble is the most obvious manifestation of clock difficulties but there are other symptoms: I remember Brian Hewson being irritated just on principle that I had played an automatic move in a tense position - after the game it became clear that I had missed a mate in three at that point.

So, below I'll talk around time trouble but also time management in general, and what you might want to do about it. Often, simply diagnosing a problem is to start curing it.

B. Time trouble
Time trouble is time pressure that you cannot bear or want to be rid of: different players have different views about what is tolerable. The Grandmaster and psychologist Krogius gives a horror show of time trouble examples in his book on chess psychology. He classifies the examples as follows:

B1. Causes of time trouble

Inadequate theoretical preparation
Cures: better theoretical preparation (duh) but also improved experience: with more experience of different types of position you will have improved general assessment/intuition. It is an unrealistic goal to set yourself to be able to play any type of position, but if you have a weakness, work on it.
On the other hand it is not a complete cure: Bronstein has encyclopaedic knowledge, wonderful intuition... and a marked time trouble habit.

Inadequate practical preparation
Cures: more practice, practice at speed chess

A genuinely complicated game
"This is 'normal' time trouble and I have no intention of giving it up." - Botvinnik.
There is no doubt that some good players are prepared to put in a good half-hour or so in the early middlegame in the belief that the position deserves it and the expectation that it will be rewarded by an easier - maybe winning - game later.

I remember when Kramnik beat Kasparov on the Black side of a Semi-Slav he criticised Kasparov for making a move after only quarter of an hour or so. He said that this was too fast, and that he would have taken what the position deserved - "maybe one hour"(!).

Conscious entry into time trouble
In order to upset the normal run of events. - See Game 1.

Doubts concerning analysis
"Do not search for objectively the best move because frequently there is no such move. In most cases it is simply a matter of taste - simply look for a good move!" - Spielmann
In a complex position, do not always try to resolve it tactically, but maybe just play a good positional move. (Nimzovitch)

Cure: Have confidence in your own judgement and ability, at least the courage to learn from any mistake you might be making.

Doubts linked to own style
In World Championship matches Botvinnik very often fell into time trouble in complex, dynamic positions conjured up by those wizards of the chessboard, Bronstein and Tal. Bronstein's time trouble, by contrast, was in relatively simple positions where Botvinnik had a small - maybe insignificant - positional advantage.
Cure: Go for positions you feel at home in; study positions you need to feel at home in.

Doubts linked to opponent's style
e.g. against opponent who has a large plus score against you.
Cure: win a game...!

Doubts linked to importance of the game
e.g. this move is too important, I must be 110% sure...
Cure: put such thoughts aside if you can; play the board.

Doubts linked to previous course of the game
e.g. I should have won earlier: see Game 2
Cure: think about the position in front of you!

Doubts linked to own experience
e.g. a little knowledge dangerously distracting you from your own judgement
Cure: Have confidence in your own judgement and ability, at least the courage to learn from any mistake you might be making.

B2. Effects of time trouble

Failure to react to changes in the position
Inclination towards obvious moves
Cure: Think if you can for a moment longer, try not to get in a rut of thinking.

Seeking exchanges
Postponing decisions
Playing safe and solid moves
Reliance on constant elements of the position
e.g grabbing back material too soon
Cure: To combat all of these tendencies, try to play the move that you think best meets the requirements of the position, not the requirements of your nerves.

Less strategy, more tactics
Cure: You do need to check for concrete traps, but as Nimzo says, you can sometimes short-circuit analysis of variations by a good positional move. This is appropriate even in quickplay finishes where you do not want to prolong the game.

Temptation to blitz the time-troubled opponent
Game 3: "I made the last move instantaneously - as if seized by the time pressure of my opponent. I had formerly seen that I would win the exchange, but I had but to think a little; then I would have come up with the absolutely correct idea: the other Rook must go to c8 (winning the exchange but keeping the b7 Pawn.)" - TAL
["Here it is: the hypnotic power of 'natural' moves!" - Krogius]

"It could be noticed from my opponent's expression that he had been rather surprised by the unexpected turn of events, but in spite of intense time pressure he successfully responded to the reversal of the conditions and immediately found the best continuation." - Tal

Cure:

"Instead, thoroughly analyse a plan several moves deep and play the moves rapidly" - Krogius

"Set a trap and play the moves rapidly." - Webb

It is even possible to use your opponent's propensity to time trouble: see Games 4 and 5

B3. Treatment of time trouble
"Time trouble is a completely surmountable difficulty... not only (through) training in chess technique, but chiefly with psychological training." - Krogius
Self-control is often a key to success in chess.

Follow the principal rules about chess thinking: what is my opponent's idea?

Diagnose your own causes of time trouble, and make a conscious attempt to develop your decisions and resilience in those circumstances.

Use your opponent's time: work out a provisional reply for each move, and use your opponent's time for looking at the clock

Botvinnik recommends playing training games where what you are trying to improve is use of time - making it more even or at least more appropriate to the position. He says that 90% of time trouble addicts can be cured using this method, although Averbakh adds "if so, then it seems I am among the remaining 10%... and perhaps so is the author of the method..."

C. Time management
You do see a variety of strategies for the use of time in club play: players who routinely use too much or too little time, players who have a marked "stop-go" cycle, and players who seem to be just haphazard in their use of time.
Undoubtedly you can't comment on this without respect to the position, but it is worth reflecting on your own patterns of chess play. I have routinely marked the times taken by myself and my opponent for years - a minor additional distraction and I have found it valuable food for thought. I believe it has led to me making better use of the clock, which is to say, to use time when I need to use it, and get on with it when I don't.

There are marked differences in the way people use the clock, but I might be permitted a general observation or two:

Better players use more of their time than worse ones. Moral: chess is hard, and the longer you think the better, provided you have something to think with - that is, you have an understanding of that type of position and have ideas about the issues at stake.

Better players think when they are supposed to: that is, when there is something to think about - as opposed to just dithering in a level position. They are better at judging the critical moments and turning points of a game, so that when they are short of time later, the moves may be easy to find because the game is decided by that point.

Here are a few natural histories of the chess clock:

C1. Regis, Hampton, 1993 (Game 2)

White's total elapsed time is shown above, and Black's below; control at 40 moves in 100 minutes. White lost on time at move 39.

This is the only game I have ever lost on time, and some of the reasons are to be found in the notes. It was quite in Krogius' class of doubts linked to the earlier course of the game.

But on the graph you can also see some interesting features of the use of time: Black having some periods of slow play, followed by fast play, whereas White's use is much more even - however, White was unable to speed up at the end of the game when approaching the time control. It may be the ideal style is more even than Black's and less even than White's!

C2. Tal-Bronstein 1960 (Game 6)

This chart shows the time taken for each move rather than total time, and is taken from the Furstenburg/Bronstein title "The Sorcerer's Apprentice". White above the line and Black below. Who won?

"...Tal played the first seven moves with great confidence, accepting my Pawn sacrifice. With his next five moves he tried to justify his decision."

"With hindsight one can see that from moves 18 to 24 Tal used a lot of time, trying to reduce the pressure of the Black pieces, but it was in vain. It would have been better to use this amount of time, about one hour, to play the opening more carefully."

"This is only one example and the reader who is interested in this aspect of chess should start recording times; it might well be that his chess improves immediately."

C3. Botvinnik-Tal 1960 (Game 7)

Move by move, with notes by Tal:

W13: "The text move is the most precise, but the time spent in thinking about it proved that Botvinnik had not played competitively for some time. Why was it necessary to waste ten minutes out of an allotted two and one-half hours to play the most evident and surely the strongest continuation of the previous move?"

B14: "Black took a long time to choose which plan he would use in the middle game."

B18: "A rather long think for this move - sixteen minutes. Black was calculating whether or not he should temporarily pass on his idea and carry it our later."

B23: "It is interesting that Black spent fifteen minutes thinking about the move that immediately followed the piece sacrifice. … This is but a confirmation, if it can be expressed this way, of an intuitive sacrifice, a confirmation of the fact that Black did not calculate all of the variations beginning with the sacrifice and ending with mate."

B28: "(After disturbance by spectators) I consciously chose the less strong but safer continuation."

B36: "Beginning with the 26th move, Black has been playing lightning chess."

B41: "Forty moves had been made but the opponents remained in their places. Obviously, Botvinnik considered that since Black was playing at such a rapid speed, he must have made a mistake somewhere, and as for me, I was still full of energy."

Suetin has gained the advantage and steadily increases the pressure. Korchnoi was able to divert his opponent from the measured tempo if his play only by provoking his own time trouble.

Suetin incorrectly believed that he had the chance of an early win, began to hurry, committed some serious errors and lost.This game decided first place in the championship.

Black was visibly upset by this move.

I know from playing the Modern myself that few 1. e4 players will transfer to a Queen's-side opening, but that's always been where my heart is.

I was feeling quite pleased here: that I had both a chess and a psychological initiative out of the opening. I don't think I have played Benonis any more often than my opponent but have looked at this type of position and felt at ease with it. 12...Nc7 36m
