First of all, this is a tough spot.....That said, with all due respect to John Hendy, his shot, that a lot of you like, looks no good to me, because >>> As the balls are laid out here, the 5 looks like it will carom off of the 7 and into the 4, selling out...and if you carom the 7 too full, it clips the 10, selling out...and if you manage to have the 5 clip the 7 thin enough for it to squeeze through and miss the 4, then it hits the 3, selling out.
I only see one viable shot here, and it's the shot that I would shoot - if you're playing on a table that you know well, so that you've got your rail familiarity and table speed down, it shouldn't be that hard to execute - you'll have about a 6" margin of error speed-wise....
I'm taking a scratch by lagging 2 rails, short rail and then long rail, passing behind the 9 (just gotta watch out for that side pocket), having the cue ball end up on the top rail between the 7 and the 10, and there's also the possibility of softly clipping the bottom side of the 7 for a legal safety....The beauty of the shot is not only do you escape the trap, but you've got your very valuable 14 ball protected/hidden from him also.
