There, Paul Foster took first place, defeating David Groner, recent winner of the Metropolitan Open. Al Tesaro took the consolation. Paul Coppenwrath won in the intermediate section, and William Evans was victorious among the beginners.
In his 19-point semifinals match, Foster had to work hard to overcome Stephen Carr, director of New York’s Bar Point House of Backgammon. Carr, trailing 17–15, made a key play that enabled him to tie the match, 17 to 17.
In the diagram, Carr (Black) and Foster (White) have each made important early gains. Black has constructed a better home board, but White has already escaped with one back man. Black’s major objective now is to prevent White from getting away with his only remaining back runner. At any time, White could roll a 6 and run away. To stop White, Carr realized that he needed to make his bar-point (the 7-point). With this point, he would form a solid 5-point prime, from which White would have great difficulty escaping.

Carr found an even more effective way to gain control of the key point. He played 8/7, 6/1*, slotting the bar and simultaneously hitting “loose” on the 1-point.

Hitting on the 1-point serves several purposes. Primarily, it keeps the man on the bar-point safe. By keeping White temporarily occupied, it also virtually eliminates the immediate risk of White’s escape from Black’s home board. In addition, hitting prevents White from developing his own position by making a point on his side of the board.
