At that time it wasn't solved and it was unknown whether Chinook was at Tinsley's level. Now it's solved in the sense that a humongous computer search has proved it to be a draw, but there is still competition between humans. Chess is generally believed to be a draw too. A mathematical or computer proof of that wouldn't change things very much though. The best way to beat another human might involve playing into positions that are lost for you, if you can get into a complex enough position to confuse your opponent into a mistake.

My brother and I would tie checkers every time if we were paying attention.

It’s basically like ticktacktoe. You have to be unaware of like 3 moves to lose.

Edit: Oh I guess when all pieces are stuck the last player with a move wins? We never knew that and would just call it a draw and play a different game instead.

I'm not a checkers player but really strong players do win games against each other. Also it was 8x8 checkers that was solved. Human competitive play is sometimes 10x10 which is probably beyond current technology to solve the same way. Tinsley played 8x8 though.

Yeah TIL in order not to be stuck moving your last piece before the other player, you need to make a smart sacrifice then force the other player into running out of moves or pieces first.
