Lobster: Yep I've thought about that...and yet it's too complex. We Chinese have a chess-like game called "Wei Qi", and "corners" and "edges" play an important role in the game. I don't know how to play Wei Qi while I bet if I could play it I would be more likely to solve the puzzle in MineSweeper.
Also, according to your suggestions, I've uploaded a version that [o] always opens the cell with the highest chance (no metter how low the highest chance is). Still there are some tricks but [o] never cheats.
Choli: Thanks
I've uploaded a new version, with some GUI improvements. As for the Easter Egg, it's dedicated to my friend and has something to do with the About Window. Aim your mouse and click four letters
You could try to deassemble my program but I wonder how you'll like it
