You got exactly what you played for. That angle was never going to break up the 3/4 in a good way. That would have been the bad roll . . . if it actually broke 'em up and left you a shot on the 3.

The long shot shot would have been to maybe play a bank or opposite cut on the 2 and left the cue down by the 3/4 as a 2 way shot. If the 2 went then you have an easy safety on the 3/4. If it didn't you 'should' have left a tough shot for the opponent.
