Crafty v20.14 << recently upgraded :-) >>

Running on the server.

This account is integrated with the Crafty chess software for Linux. It is used by the administrators to provide automatic computer analysis of games.

How to interpret Crafty analysis:

♙ "Nodes" is the number of nodes analyzed to reach its conclusion (measured in millions.)

♙ "Ply" indicates the depth of the search, in half-moves. E.g., "Depth 14 ply" means that all possibilities for the next 7 moves have been considered by Crafty.

♙ A numerical evaluation is shown. Positive numbers mean that White is winning; negative numbers, Black is winning. A difference of 1.00 is one pawn of value.

♙ After several moves a symbolic evaluation is provided:

+- White has a decisive advantage
-+ Black has a decisive advantage
± White stands better
∓ Black stands better
⩲ White has a slight edge
⩱ Black has a slight edge
= Game is equal

Crafty is a direct descendent of Cray Blitz, the World Computer Champion from 1983 to 1989. You can see some games played by Crafty on our Crafty (Computer) page.

NOTE: Crafty is good, but not always 100% correct! Use Crafty as a tool for analysis, not as the final word.

Dec-16-08  govert: Hello Crafty!
Could you please tell me how I could use you to find the top 3 moves in a certain position...
Dec-21-08  WhiteRook48: Crafty I don't know the site but it's Morphy vs Duke Karl/Count Isouard 1858. After 1. e4 e5 2. ♘f3 d6 3. d4 ♗g4 4. dxe5 ♗xf3 5. ♕xf3 dxe5 6. ♗c4 ♘f6 7. ♕b3 what is the best move for Black?
Jan-01-09  WhiteRook48: I think it might be 7...♗d6. If 8. ♕xb7 then ♘d7 and saving the ♖. Black has to sacrifice a pawn though. White might also play 8. ♗xf7+ but at least black saves that a8 Rook. or is 7...♕e7 totally better?
Premium Chessgames Member <Hello Crafty! Could you please tell me how I could use you to find the top 3 moves in a certain position...> Sorry, that's not a feature that Crafty offers. However Toga (Computer) is able to show the top 10 moves--that's one of the main differences between Toga and Fruit (Computer), from which it is derived. Currently, we only use Toga to help us analyze Guess-the-Move games, but in the future we hope to make Toga's analysis features available upon demand, at least to premium members.
May-27-09  tibone: hi crafty!
could you please analyse the final position in
Junior vs Huebner, 2000?
May-27-09  zanshin: <tibone> I had a look at the position for you with Rybka 3.
Jun-08-09  tibone: thank you zanshin
Jun-08-09  tibone: hi crafty!
could you please analyse the final position in G Lovas vs H Muller, 1935 ?
Jun-08-09  zanshin: <tibone> I had a look at this game for you too. I wonder if these games have incomplete scores because players are resigning early .. sometimes when they are even ahead.
Nov-21-09  hedgeh0g: Crafty, my Fritz 11 is quite lonely and would like a companion. Could you do me a big favour and take it out to the cinema or show it a few variations or something? Anything to get it out of the house.
Jul-02-10  WhiteRook48: is there a win in this position

black to move

Jul-02-10  zanshin: <WhiteRook48> I think the position is drawn because of the stalemate. I checked with Rybka 4. White's rook checks and captures with impunity, until Black is forced to capture it.
Oct-23-10  David2009: <WhiteRook48: is there a win in this position> No for reasons given by <zanshin> - no need for a computer. However let's add a Pawn at c7 and now Black wins. See for yourselves against Crafty End Game Trainer:

Alternatively, solve the puzzle colours reversed (White to play and win):

Or, finally, <WhiteRook48>'s original position adapted as White to play and draw:

Nov-12-10  David2009: CRAFTY EGT TIPS AND TRICKS: What better place than Chessbase.comís crafty chessforum to set down some hints, tips and tricks for using the free-to-use Crafty End Game Trainer kindly provided by

First, a disclaimer: I am an ordinary (non-premium) member of but have no other connection with them. I discovered the EGT when practising end games and slowly but surely learning to win with KQ versus KR. The EGT seems to play 4-man endings perfectly but predictably using a 4-man Nalimov tablebase. Bizarrely, this means that I am now very confident of winning Q v R against a computer Ė but not necessarily confident of winning it against a strong master who will rapidly surprise me with good but sub-optimum moves.

So how can you set up positions? Be aware first that the EGT always plays Black. So does <endgamebot> as provided by <Ludens> on the Free Internet Chess Server (which plays six-men endings perfectly using a tablebase). So you may want to set up a position colours-reversed. There is a quick way of doing this which is a subject for a future post.

Next, check that you have installed Chess Viewer Deluxe the default viewer (visit Chessgames Help if in doubt). Chess Viewer Deluxe allows you to analyse variations by dragging-and-dropping pieces, to copy diagrams (as FEN strings) and to copy game scores (including your analysis). Importantly, you can also copy positions that you have reached in your own variations analysis that you for the game in question. Visit Kibitzing Tricks for help with FEN strings if necessary.

You are now ready to set a desired position (White to play) up in the EGT. This can be done in the following steps:

1. Open up the Crafty Board Generator

2. Compose your position either by drag-and-drop or by pasting in a FEN string.

3. Add a suitable title. This is not essential but otherwise your Inernet Explorer history will end up with a confusingly large number of web sites all labelled 'Custom Crafty Position'

4. Generate the position - and enjoy playing it out against Crafty EGT.

Mar-26-11  YourNickname: Why doesn't Rybka have an account? He is much better then Crafty.
Mar-26-11  Open Defence: Crafty pulled the plug on Rybka...
Mar-28-11  YourNickname: Rybka is jammed by Crafty's tears you mean. Rybka beat Crafty so hard, that Crafty was going to think like a human :p.

  Penguincw: Cool. A computer.
Dec-27-11  Counterpoint: Crafty, can you please evaluate the position after 49...Rxb2 for this game:

  offramp: I hope everything is okay with you, <Crafty>. We haven't heard form you in a long while.
Apr-27-18  posoo: COMPOTERS do not DIE they just BECOM USELSS like humans.

I do NOT miss da Cruftoy, he had NO PERSUNOLATY!

Apr-28-18  N0B0DY: <pooso>

<N0B0DY's> willing to look at old scripts again, and <N0B0DY> wants to see what you've been writing for hire. Call everyone in your phone book and have drinks with them.

(Separately.) Remind the world you're alive. Reenter the thick of things.

  offramp: In his house at Cruftoy, old Crafty waits, sleeping, known and favoured by a nightmare cult ready and eager to loose him upon the world whenever another chess position proves too monstrous for human brains to contemplate.
