In general, this is a great application, thank you! So far I found one small inconvenience - once the game is saved as a pgn file, you can't smply associate it with the application. Right-clicking on the file and selecting greenchess as the application to open it does not seem to work, greenchess complains that it can't open text files.

Nice graphics and choices and stats, though not all explained and Al is fast and tough on the most difficult. Problem I have is it counts Stalemates as Checkmates. Also I don't think you can choose to play as black.

…if you are a chess player then this is really well designed and I thank the developer for sharing this prgram he created. If you are a novice player, or a child, or an adult that plays likes a child (me!), then this is still too powerful even when set at the lowest level. Hence, for me, it’s a little discouraging to lose all the time. However, playing with a stronger player will hopefully make me a better player.Again, thank you George Merchant!

Is it possible to castle?Many good features… but if ya' can't castle what is the point? It's too hard to enjoy something with a problem like that. Can somebody just make an app that makes that move possible? Has someone?
