There are two critical positions.
No. 13.
No. 14.
In Diagram No. 13, if White moves 24 19 he loses, because Black goes to 11, and as the tailors advance to head him off, he goes back to 15 and 18, and then gets round by going to 14. White’s proper play is 22 18, after which 26 22 will reform his line.
In Diagram No. 14, if White moves 26 22, or 19 15, he loses immediately. In the first case Black will run to 15 and 11, and either get round or double back to 18. In the second case Black will get round by way of 7, or get through.
