Thinking Machine

Today I played over the board while playing level 3 of Video Chess, and after a long game my opponent checkmated my king, but if I would have castled I could have avoided it?

It was still a good game and the screen would flash longer because the computer had to think harder about where to move later in the game when calculating my moves on the board since I was still playing at the fullest, and that's why it was such a long game of chess!
