How Many Possible Moves are There in a Chess Game?

The answer is pretty astounding. We were intrigued by a recent article in the UK Guardian on the subject. Surprisingly, after doing some additional research, we found there are a number of conflicting answers to the question. This is most likely due to the amount of questionable information on the internet.

To keep things simple, we will report on a different question where we found a consensus of answers. How many possible positions are there after each player has made three moves?

The answer is surprising if you are not familiar with how fast numbers grow using permutations and combinations to calculate these types of answers. Does anybody remember this formula?

permutations

There are over 9 million combinations of moves after each player has had three turns. But the number of unique positions is much smaller, only 311,642.

That is why it took a long time for people to develop a computer program that could play chess well. Humans have the ability to discern the difference between good and bad moves based on their knowledge of strategy or even after they have played a game a few times. Computers need to crunch all of the numbers and use an evaluation system to figure out which of the many combinations of moves makes sense.

World Championship $

Rules of Chess Quiz

Below are some trivia questions on official chess rules (per the USCF Official Rules of Chess 5th Edition).  Test yourself and see if you are a grandmaster of chess rules:

Piece Movement

1. Piece Displacement: It is your turn to move.  Your opponent decides to make a note on his score sheet and accidentally knocks over a couple of pieces.  What should you do?:

a. Give him a dirty look, check your score sheet and reconstruct the position.

b. Hit the clock, and ask him to fix the pieces, the restart the clock on your time once he has corrected the situation.

c. Call the tournament director and ask him to assess a 2 minute penalty.

2. Castling: You decide to castle kingside and move your Rook first, then move the King to complete the maneuver.  Your opponent claims this is an illegal move and advises you must move the rook.  Is he correct?

a.  Yes.  You must move the Rook two squares and leave the king in its original position.

b.  Yes, but you have the option to move the rook one or two squares.

c.  No. There is no penalty (unless castling is illegal because one of the pieces has been moved already).

3. Touch-Move: While reaching for a Knight, your opponent’s forearm brushes the Queen and knocks it over.  What is the correct ruling.

a. There is no penalty.  Your opponent should put the queen back in place, then make his intended move.

b. He must move the queen since he touched it first.

c. There is no penalty, but the director should issue a warning.  If it happens again, your opponent must move the   piece he touched.

4. Drop-Move: A player in the process of moving his bishop, accidentally drops it on a legal square.  What’s the ruling?

a. The bishop must remain on the legal square.

b. Since it was an accident, he can pick up the piece and move it to the intended square.

c. The director should poll players on neighboring boards to see if anybody observed the move.  If he has sufficient evidence that the piece was accidentally dropped, the player can pick up the piece and move it to a new square.

5. Pawn Promotion: A tense game between two masters is in progress.  Player A moves his pawn to the promotion square, not realizing that player B has set a trap.  If player A chooses a queen, the game will be a stalemate.  Player A picks up a queen on the side of the board and sees the trap.  He then puts the queen down on the side of the board and chooses a rook instead, placing it on the promotion square.  Player B claims a draw since player A touched the queen first.  Is player B correct?

a. Yes.  The touch-move rule applies here.

b. Yes.  Once a player picks up a piece, it cannot be deemed an accident.

c. No.  For pawn promotions, the move is not determined until the player chooses a piece and releases it on the promotion square.

Draws & Stalemates Quiz (see below for answers)

1. Stalemate question: Player “A” picks up his knight and places it on a square.  Shortly after releasing the piece and hitting the clock, the flag falls on his opponent’s clock.  The opponent, Player “B”, notices that the last move put him in stalemate.  What’s the correct ruling?

a. Player A is the winner.  The other player needs to make the stalemate claim before his flag falls.

b. Player A is negligent.  He must announce stalemate after making the move.  The director can rule the game a forfeit due to his lack of proper etiquette.

c. The game is drawn.  The stalemate occurred before the flag fell.

2. Draw offer etiquette:  What is the proper procedure if you would like to offer a draw?

a. When it is your move, after you hit the clock.

b. When it is your move, before you have hit your clock.

c. After your opponent has moved and hit his clock.

d. Extend your hand to your opponent, if he shakes it, the draw is official

a. Yes – the player wishing to make the claim, may stop the clocks and have the director make a ruling by demonstrating the ability to force the triple occurence.

b. No – once notation has stopped, there is no way to verify the claim.

c. Yes – the player who wishes to make the claim should announce, “once” then “twice” and finally “thrice” as the three positions occur.  He can then claim the draw based on the prior announcements.

d. Yes – as long as both players have more than 60 seconds left on his clock.

Chess Jokes

Correspondence Chess Joke (courtesy of the Chess Zone)

Two chess players, Vlad and Igor, decide to play a game of correspondence chess. The only problem is that Vlad is at the North Pole and Igor is at the South Pole, both at totally remote outposts.

However, they have devised an ingenious scheme where every month, they arrange for a team of huskies to battle the elements from the respective base camps to the outposts in order to deliver the moves inside a weatherproof vial, strapped to a dog’s neck.
This plan works fine for a few years. By move 27, the game is reaching the critical middle game point, where a wrong move would mean disaster for either player.  It is Vlad to move, and for some reason, Igor does not receive his move on the normal date.

Two months pass, then three, then six, then a complete year. By now, Igor can hardly stand the suspense and is climbing the walls with frustration. Suddenly, he sees a team of huskies approaching through the blizzard outside. He rushes out, and with trembling hands, opens the container. He unfolds the paper and can hardly bear to look at it. He tentatively opens his eyes and scans what is written on the paper:  “j’adoube”

Obsessions

(Two old friends get together after work for drinks and catch up on things)

  • Joe:  “How are things, do you still play chess like we did in the old days?”
  • Larry:  “Sure do.  In fact, I play almost every weekend down at the club.”
  • Joe:  “That must be tough on your personal life.”
  • Larry:  “A couple of months ago, I told my wife that I was going to play in a tournament on our anniversary.  She told me that if I went to the club that night, our marriage would be over!”
  • Joe:  “Wow.  So what did you do?”
  • Larry: “I played Nf3.  I always play the Kings Indian Attack!”

Celebrity Chess Quiz

1. g, 2. a, 3. f, 4. b, 5. d, 6. c, 7. e

Piece Movement Quiz:

Question 1 = b: A player should not lose time on his clock because his opponent has displaced pieces on the board. Since the player not on the clock has knocked the pieces over, it is appropriate to start his clock and ask him to remedy the situation.

Question 2 = c: Despite what some people might tell you, there is no penalty for moving the rook first while castling.  However, if castling is illegal due to the previous movement of the pieces, the player must now move his rook.

Question 3 = a: Accidentally brushing a piece while reaching for another does not meet the requirements for touch move.  The player may move the piece he intended to after fixing the piece that was knocked over.

Question 4 = a: This is a special case.  Since the piece was legally touched and was then dropped on a legal square, this would be ruled as a completed move.

Question 5 = c: For pawn promotions, a move is not determined until a piece is selected and released on the promotion square.  The first player is allowed to change his mind as long as he has not placed the piece on the promotion square and released it.  Changing the selection and placing the rook on the promotion square is legal.

Draws & Stalemates Quiz:

Question 1 = c: USCF rules state that once the piece is released on the square, the move is “determined”.  If this results in a stalemate, the game is over immediately.  So if the player completes the move by pressing his clock and the opponent’s flag falls, that is irrelevant as the stalemate has already occurred.

Question 2 = b:  The proper etiquette is to “determine” you move by placing a piece on a square and offering a draw.  Then you can complete the move by hitting your clock.  Note that a draw offer may not be withdrawn, so once you offer it, your opponent may consider it for as long as he likes until he makes his next move.  If you offer a draw before moving your piece, the opponent may accept it immediately OR he has the right to ask you to make your move first – then he can still consider the merits of accepting or declining the offer before he makes his next move.  Offering a draw during your opponent’s move is considered bad etiquette, however once the offer is made, he can still consider it and accept it.

Question 3 = d:  The proper way to make a claim in this situation is to write the move down and stop the clocks.  If your opponent does not agree with the claim, you may summon the director to verify the claim.

Question 4 = a:  This is the only correct answer.  The player stopping the clocks can call over the director and if an impartial witness or deputy director has observed the sequence of moves, the draw can be upheld.  Alternatively, as noted here, the player can ask the director to observe the match and they can play on.  If he can demonstrate the triple occurrence the director may rule the position a draw.
