The lesson in words
When your opponent has four in a row with an empty point at the end, they win next turn unless you block it. That comes before anything else.
Ivory has four in a row. You blocked one end earlier.
Try it: Stop Ivory making five.
An open three is three in a row with both ends empty. If it isn’t blocked, it becomes an open four, with two winning points, and one stone can’t stop that.
So block an open three straight away, at one end.
Ivory has an open three.
Try it: Block the open three.
Block fours at once and open threes straight away. Test yourself in the rules check.
