And then I'd play the cue ball as full as possible into the 6 to drive it as thinly as possible into the 9 and freeze the cue ball to the 7 while taking the 6 to the left end of the table. If the actual ball positions don't allow that, I might play for a nearly full shot of the 6 into the 9, the 6 stops in place, the cue ball follows to hit its right side and the cue ball rolls to the right behind the 7. Either of those plays depends on the precise positions of the balls, but there are good possibilities.I'd intentionally foul back at you.
Someone recommended picking up the cue ball and handing it to the opponent. Technically, that's not permitted. Strategically, you are better off doing something else, like freezing the 8 to the cushion.
