There are so many bugs in Chess Titan Game included in windows 7 OS, This Game was developed by Oberon Games.
I found not only same bug once but many times;
Here is one.
You can see Computer move BLACK QUEEN on Top left
Then I moved Pawn (White Soldier), bottom left 2 Steps Ahead
It’s not only Kill the Pawn but Move one step ahead too.
I am sure Microsoft added it without checking.
