What Game is played on a black and white checkered board similar to chess with 100 squares?

The game you're describing is likely Draughts, also known as Checkers.

While the board is traditionally black and white checkered, it has 64 squares, not 100. There are variations of checkers played on different sized boards, so it's possible the game you're thinking of has a unique setup.

Could you provide any further details about the game? For example:

* How many players are involved?

* What are the pieces called?

* What is the goal of the game?

* Do you know the name of the specific variation?

With more information, I might be able to pinpoint the exact game you're thinking of.
