Robertie suggests not hitting since blue is outboarded. But we need to hit to win this game and by our next roll white is going to have a five point home board. Now is the time to take our chances.

Naturally, if white had a five point board now hitting would be a huge blunder.

If we bring one of white builders from her 2pt back into play, hitting becomes barely wrong.

In the OP threes are duplicated for white to enter and hit our blot on the 3pt and cover her ace point. If we diversify white numbers, then the safe play gains in relative equity.

Finally, if there is no blot in white's home board then the safe play is clearly best.
