Great concept and nicely done, HOWEVER the puzzles themselves are uneven. Some are relatively easy (say, mate in 2) and some are pretty difficult. This would be OK if they were arranged in order of increasing difficulty, but they aren't.

That is forgivable, but what is disconcerting is that at least one puzzle (#5 for me - I assume they are in the same order for everybody) does not have a mate solution. Crafty is analyzing that puzzle now and is at 14-ply now, with no mate in sight.

It's hard to complain with a free widget. Let's just say there is a bit of room for improvement.

I am really enjoying this widget as well. On a very minor note, I ran into mistake in the engine on puzzle #64. It stops the puzzle as a checkmate even though black could still move en passant to capture the offending pawn. Is en passant movement excluded from the engine?

Since v 2.1.2, the engine has been able to capture en-passant and in fact does this when I play out #64. Please make sure you have the latest version and feel free to contact me.

another thing that might be nice is a minimized state for when you aren't using it, it takes up a lot of room. that is fine when i'm messing with chess, but when i'm not i'd like that space back and i'd like to get it without having to close chesspuzzle.

i think this is pretty great, though it seems that the computer can't guide you through some of the puzzles in some instances. i don't know why it happens, but maybe it has something to do with leaving dashboard-- but i've had several draws when only clicking on the "!" button-- which is supposed to show you the proper move for that puzzle, right?

also, it would be nice if i got feedback for every move so that i know if i've gone astray from the solution.

all said, i'm enjoying this-- thanks to the developer.

I really really like this widget. I'm just starting to learn the game and this widget is helping me to become a better player. The interface is dummy-proof and the features are useful and enlightening. This is the only widget I use everyday and I am grateful for its development. Thank you Applepi.

Way cool widget! I love it. And the engine is pretty strong, too. (I'm a 1900+ player, and this thing is hard to beat at 5secs per move...)
I'd like to see the full source of the combinations (e.g. Nimzovitch vs Euwe, Karlsbad 1929). Could this possibly be implemented?

Hey, and keep it free ;-)

This is a terrific widget. I love that the newer version can work through the whole puzzle to the end (in case your first move was just a lucky accident!) I have had no crashes or bug problems using it on a PBG4.

Version 2.1

Great job!

Will developers please incorporate the version number in the download file. Thanks to Tiger or Safari or both I keep getting Version 2.01 because of the aggressive caching of 10.4.2

Drag and Drop was the most requested feature but I wanted to wait until the engine code was solid first.

Enjoy, Bob.

The best widget I have come across ... and there are a few of them. The implementation, as far as I can determine, is perfect - there is quite a complicated interaction between board, controls, chess engine and move list yet it is carried out effortlessly without any bugs or unexpected behaviour I can find - and the chess engine rounds things off off nicely. I spend all my time pressing Alt-P to set up the start position then playing it rather than solving the puzzles!

Although Sjeng is a strong engine - I am a 2000+ player yet struggle against it - I note that the "opening book" described in the settings seems to be very small as, for example, it is out of book on move 3 in a Sicilian (e4 c5 Nf3 Nc6 d4 ). Where did it come from?

It would be useful if games could be saved, even if only to something crude like a log file. As long as the moves can be picked up by a text editor ...

Hi thebrix,

First, thanks for the kudos -- I put my all into this widget. Check the download page to see what's planned for v 2.1.

Next, you're right! I had to fake the opening book. Sjeng will not use a book when setboard is called and that is the only way I wanted to interact with the engine: bring it up, setboard, get move, bring it down. This way there is no possibility of leaving hanging processes open, and 'play a full game' was kind of a bonus -- its really a puzzle solving widget.

But, I'd be happy to chat about expanding the opening book with you. Give me a shout anytime.

I've added 'Export To PGN' as a feature for future release.

Probably just by putting it on the clipboard. Import from PGN may also be possible via paste from the clipboard.

Thanks for the suggestion.
