I'm not trying to play results but the kick shot was a bit of a stretch for a B player and below. Plus the 14ball is a big ball for Mr Rubble, not only does it go in Barney's pocket and not in Fred's but it also opens up the cluster for Barney if and when he should get to it. With this understanding and really no good option available ...thinning off the 14ball with left english and spinning two cushions around and ending up with the cue ball near the 15ball on Barney's side of the table is a good option. This option will open up a couple balls on Fred's side of the table plus take away the advantage with the 14ball that Barney has and position the cue ball where Barney will have only a passive safety for a return shot. Imo the kick shot was not a high percentage shot and had to be hit exceptionally good to benefit by it. Also, imo the kick was just as easy to hit bad as it was to hit good, so my contention is to shoot a shot that you can hit good 98% of the time and protect your 2 to 0 lead while building a stronger position and protect it.
Another passive yet effective option would of been to bank the 15ball to your side and position the cue ball close to or frozen to the 3ball. From that position Fred would not only gain a stronger position but would also have the next good move because of where he would of positioned the cue ball.
However, if the 6ball was positioned to play Vapro's shot then of course that would be the shot but if not then the two somewhat passive shots that I described would then become worthy of shooting.
