MacBook Air Yosemite shuts down suddenly

[Kouga]

Hi all,
I was using my macbook air 2012 normally, opened chess game and then suddenly it shuts down as if I was pressing the power button not a normal shut down, I pressed the power button and it boots normally, but I want to know what happened and what causes my mac to make so, it was the second time. And Iam afraid from later results, please help me.

I had a hackintosh a long time ago and it would do this with the chess game too. I'm surprised that it happens with a real Mac but that game seems to have some sort of horrible bug. Don't worry about it and find a different chess game if you want to play chess.
