Go games have been recorded for centuries using paper and pen.

How To Record a Game

Today, a game record may also be created using an SGF editorbut the manual approach is still the most convenient in many cases. First, obtain a game record form. Mark the handicap stones, if any, by simply drawing a black-filled circle for black stones, and an empty circle for white stones. The number of each move is simply written on the location where it was played.

Black moves are entered with a black pen and White moves with a different color such as red. Two-color pens are sold for this purpose, or you may just use two pens, taped together if you please. The point of using two colors is simply to make the game record easier to read. Use a pencil if you prefer to make it easier to erase mistakes.

In any case, the first black stone will be a black “1”, the first white stone a red “2”, etc. Whether or not you use two colors, you may wish to circle the moves of one color, normally white, to distinguish them.

If a move is made on a point where an earlier move was made, e. For example, if Black 49 takes a ko on the point where Black 37 was played, you write “49 at 37” or even “49 takes ko at 37”. If the location was previously occupied by a handicap stone, use the “49 at left kivu 22” notation, where 22 is a move played on the point to the right.

It’s possible, though less common, kkifu use board coordinates to indicate where a move was played. If the point where a ko is being taken is obvious, it suffices to just write “49 takes ko”. A ko or other connection might be “49 connects”. It’s very easy to make a mistake while taking a game record, and difficult to recover. The most common error is forgetting to increment the move number. This can be avoided by quickly checking mentally each time you record a move that the move number is odd if it’s a Black move and even if it’s a White move in a handicap game, of course, White’s moves will be odd-numbered.

A better approach should deal with the fact that the recorder cannot overwrite or erase anything. I am working on a program that uses a webcam to watch a go game and automatically takes pictures at 10 frames a second. The program then automatically analyzes the images and creates a game record that you can edit and then export to SGF. Info is here with a link to a video. Has anyone ever used a digital camera, or a mobile phone with a camera, g record moves? A picture every minute or so depending on playing speed, of course could later be used to reconstruct the game e.

With the new Java-enabled phones it might even be possible to program it to make a picture regularly, so all you need to do is position the phone and start the recording program but I don’t know how far the gp between phone and Java goes. To take it further, you could even write a program to automatically analyze the pictures and create an SGF file from it.


I’m guessing it shouldn’t even be too hard kifh after all, the board is a pretty simple shape and the stones have very good contrast. At least the analysis should be easy if the camera is positioned before play on a kkfu or such. Also, the signal to take the picture could be integrated with a game clock.

Or indeed camera or why not a webcam could take the a kkfu every second. Gl analysis program could gk determine from the pictures which of them has the next move by checking if there is a difference on the game state. This might even be used to eliminate errors in picture analysis: Two interesting projects in this area are GoCam and Chris Kofu ‘s image2sgf.

The iOS app Baduk Cap has automatic move recognition and allows to take pictures at pre-defined time intervals. I used a camera to take a picture of the final position and kigu during a game as a help for reconstructing the game. Taking a picture every minute would be quite annoying and not much of a help messing with dozens of pictures isn’t much easier than reconstructing the game. The idea should be to help you in reconstructing it, not technical overkill.

Similar to translator notes or so I have to a sheet of peel off numbered stickers, black and white for odd and even numbers. These eliminate the common error of writing a number out of sequence.

I think they were available from the British Go Association shop. Actually, it is quite usual that also in handicap games the white moves are counted beginning with 2.

It always feels very weird when the white moves are odd-numbered. If the handicap stones are not specially treated in the beginning, then the ko notation “49 at left of 22” special case need not occur. I advocate numbering the handicap stones normally, just as if white had passed the first N times. Of course, if you’re just recording ggo for your own benefit you can use whatever system you like. But we don’t really need multiple methods of recording games, and if you intend your game records to be understandable by others it is better to use the existing fo as it is used by millions throughout the Far East, in which handicap stones are not numbered.

I’ve been trying to record a game twice now: It was moves or so. While it’s nice to have a record, I feel that I had to pay a lot of attention to it, which was probably detrimental to my game.

Right after buying a palm, I used it to record some tournament games. I soon stopped doing it, because it was a distraction. Nowadays, I bring it along to the tournament, and if I want a record of a game, I just do it after the end of the game. At the latest in the endgame my memory gets fuzzy, but usually the moves worth reviewing are early on in the game.

Using a Palm to record games causes me to slow down a little and consider my moves more carefully I have found that it prevents go-blindness, in which I occasionaly dont see an atari due to being too focused on a different move.

So, my experience is that recording ones games is beneficial. I am also making it kjfu habit to replay at least part of the games that I play on KGS. I use my Palm, even during tournament games.

I find that it’s more useful for study to have the games, even if it might be detrimental to my play. I learn more from having a record of my “serious” games then I do from trying to remember three games at the end of the day. I also think that my memory is faulty — the parts that I don’t remember well, like ko fights kifi the end game, are also parts where I’m making gi mistakes.


I usually can remember the opening and the beginning of the middlegame, but I don’t feel I have as many problems there. That being said, I think the Palm is the easiest way to record, without having to remember what number you are on, who’s move you recorded, etc. I was able to record fairly easily, even in second byouyomi.

Back when I was playing more or less seriously, I found it very helpful to record my games in real time. I also made a note of which plays took me more than one minute to play. That’s an idea of Botvinnik’s. Plays that take a relatively long time indicate positions that you find difficult and thus suggest where to focus your study.

I used to do it quite simply.

I drew a board with ruler. Then I went to the departmental college photocopier and copied it. Still have about a have dozen of these sheets in a file folder. I think it has some advantages to follow the chess practice of recording a players move before thinking and recording your move before playing. It did sometimes annoy other people. What I’m suprised is no one mentioned something that would often happen to me.

I would write down one move sifted by one, then use it to orient my self by it. About twenty moves later, I would realise my mistake and started fixing things. The best thing would be to just continue on another sheet.

Usually I would be able to piece together the game from the sheets. Recording should be done after one’s move — especially if the record is a diagram. It’s like trying out a move: This is much more convenient in long ko fights, since all the moves that go into the ko are recorded in the same place. If you have a pen of only one colour, then to distinguish black and white you could write White’s moves in Chinese numerals.

Then I draw out the board on the paper by hand by putting dots on the star points, and drawing a border freehand, just outside the edge of the 19×19 area. This doesn’t take very long to do. One Berlin enterprise sponsoring go events hands out kifu forms which come together with klfu transparent page. That makes replaying the game later a bit easier.

I have to record games when I play teaching games with beginners, since I find it’s hard to remember their moves. Sometimes I don’t understand the reasoning behind their moves. Anyway, last night, I was caught! The other player said, “Hey, you recorded my move before I played! He thought it was funny, though. A friend of mine and I have a habbit of each picking up the stylus and recording our own moves on the one device.

Once while playing, he was staring at the Pocket PC instead of the real board while thinking and then slapped a stone down on the screen! On a similar note, I was playing a very informal game with a friend, and was eating potato chips as I played. The game became interesting, and at one point, while I was concentrating on a particularly difficult sequence, I put a stone in my mouth, thinking it was a potato chip.
