What is the chess board pattern called?

[Mynx]

I'd like to know what the name for a black and white squared chequered floor (or any surface) is. I can't get Harlequin out of my mind and I know it's not that. I'm sure this pattern has a name but I can't find it either in the recesses of my brain or on the internet. Please help!!

Yanks call it checkerboard and that seems to be influencing the names over here more and more....you could try that.

Thanks sft42 but that's not what I was thinking of. These things really get annoying when they go round and round in your head. Thank goodness for sites like these eh?

Are you thinking of the heraldic term "checky" or "chequy", Mynx?
