There is a safe way to play the break off in Straight pool, however, it takes a few practice goes.
Place the white on the far right or left of the break off line and aim to hit the target ball (The latter ball at the bottom right or left of the rack) as thin as you can...
Note: As long as the white ball hits the rail at least 4 times, it is a legal break...
The best way to break without leaving an early birthday for your opponent.
If you struggle with this, tell me and I shall upload a quick video to YouTube.
