Re: 40000 interactive chess tactics puzzles
It looks very good! Many features.
What is the engine?
I've just drawn a game against Level 2 by repetition. But there is no PGN or notation. Maybe registered users get a PGN.

Re: 40000 interactive chess tactics puzzles
The engine is BremboCE programmed by me. In level 2 the engine is limited to deep 2. For other levels registration is required but it's free and for every user I keep stats ragarding win, lose, and draw games against each level.
Games against the computer are not available in pgn, maybe in the future... now I'm focus my work on tactics and endgame training.
I'm glad that you like ideachess.

Re: 40000 interactive chess tactics puzzles
unfortunately the site does not expect winning lines for some of the problems.
In tactics puzzle 12410
I played the following moves that lead to winning the endgame only to be marked wrong by the computer.
[Event "Computer chess game"]
[Site "URI-HP"]
[Date "2011.03.16"]
[Round "?"]
[White "Uri"]
[Black "Uri"]
[Result "*"]
[BlackElo "2400"]
[Time "13:11:37"]
[WhiteElo "2400"]
[TimeControl "40/7200:20/3600:1800"]
[SetUp "1"]
[FEN "5R2/1pq1rppk/7p/p1b4P/3p1PP1/PQ1N4/1P2P3/1K6 w - - 0 1"]
[Termination "unterminated"]
[PlyCount "9"]
[WhiteType "human"]
[BlackType "human"]
1. Qd5 Re5 2. Qxf7 Qxf7 3. Rxf7 Re7 4. Rxe7 Bxe7 5. Kc2 *

Re: 40000 interactive chess tactics puzzles
another annoying "wrong" solution and this time even the computer understand that I win the game
tactics 9511

1. ... Qe3+ 2. Qxe3 bxa1=Q 3. fxg7 Qd4 4. gxf8=Q+ Kxf8 5. Qxd4 Rxd4 6. Bxh7
Bd3 7. Bxd3 Rxd3 8. a4 Re3 9. e6 Rxe6 10. h3 Ra6 *
1...Qb6+ is also winning but the relevant line is a very simple win for black
and the computer even see a forced mate for black at the end of the line.

Re: 40000 interactive chess tactics puzzles
Hello Uri,
yes, with some problems with multiple solutions some alternative lines are not recognized as correct. Since on ideachess there are more than 40.000 tactics problems for me is impossible to spot them a priori so I count on players feedback that leave comments on the puzzle or give a low rate to it to decide to eventually remove the problem. I use the rating given by users also to improve the general quality level of the available puzzles.
Do you have suggestions for improve ideachess?
Thanks, Gianluca

Re: 40000 interactive chess tactics puzzles
Suggestion...
When you find and play the right solution....instead of just "Ok"....
why not have "Correct"..(with also maybe a smiley face too).....
Just my idea...hope you like it...
