lol Jakke, do you have any idea how hard it would be to set up an Opera chess network compatable with this widget? Awesome, but oh so hard.
Great widget, I gave it 4 stars. Would have given 5, if "you win/lose" text had appeared after completed game. Sometimes the AI is a bit too suicidal, but I can live with that, because most of times AI gives you enough challenge (at least for me).
Sorry - but this is a very poor game of chess. It's like playing a 3 year old. That doesn't make it good - it makes it silly. And I haven't played chess in about 10 years and was never any good when I did.
A pretty nice feature would be .pgn support (ie a textarea for c&p it), with forward-backward-autoplay and so on... :-)
Very nice. I now have MORE games in Opera than I do for the default games that came with Windows. This is awesome. Keep on coding! "If you are updating this Daniel it would be helpful for the game to indicate who has won, and maybe make it a wee bit harder with a few Levels." >>Also make an alert to the user that they are in check if they attempt to make a move which does not take them out of check. "One bug/overlooked rule is that the CPU will castle out of check, which is illegal in chess. I'm not sure if the player can do this." >>The Player can do this as well.
The CPU made an illegal move -- it castled in order to get out of check.
It is a bad Chess game. I played about 200 games White or Black against the computer. I need 4 to 20 moves to win every one. There are 2 logical errors: 1. If you set the King in Chess there can not follow a castling (0-0 or 0-0-0). (see: By odysseyandoracle, 17. February 2006, 20:52:17) 2. Sometimes if I play White the machine says 0-0-0 is an invalid move but it definitely isn't. I can not find an analogy till now.
I tried to get a situation of point 2 (s.a.). After some games I get one: 1. d2-d4 d7-d5 2. c1-f4 b8-c6 3. g1-f3 e7-e5 4. f3-e5 c6-e5 5. f4-e5 g8-e7 6. e2-e3 c7-c5 7. f1-b5 c8-d7 8. d1-e2 d7-b5 9. e2-b5 e7-c6 10. b1-d2 c5-d4 11. e5-d4 f8-d6 12. d4-g7 d6-h2 13. g7-h8 h2-d6 14. 0-0-0 -> invalid move, but it isn't! I hope you (the programmer) can find the error. P.S.: Essentially I would play different. The moves only should show the logical error.
There is one more error: The ComboBox 'Promote to' seems to have no effect. I don't want queens always...
A stronger engine would definitely be nice, or better still a selection of difficulty levels. I know this is more challenging than using the inbuilt script, but it would definitely make the games more challenging. When we play a low-level player/engine, we play low-level chess: no learning, no advancement. More important, though, would be correcting the illegal moves and promotions bugs mentioned previously. As a time-waster, though, it's fun and I'll keep this one. Good port.
warbird, it's the most common moving combition in chess, for me atleast . AI should bring out the other horse first.

Question, if it stops responding. And you DO happen to have them in a checkmate, does this mean you have won?
Stupid me who hasn't won a chess game in years goes on winning in this everyday! Makes me happy!
Everyone, I have made a new widget that has a stronger engine (and better support). Just click on my name. Soon, there will be a feature which will allow you to go to 2 player mode.
Does not have specific and correct rules. Plus I keep beating it...
This version is not too easy. If anything, it is a challenge and it beats me. I will have to practise on it often. It needs to have a message of when check happens and when checkmate happens. Its a great courtesy to let the other know, instead of being silent.
how do i play like i don't know how to make the pieces move?
