I've just came up with an idea (sorry golf addicts
) If a player changes cues midway into the rack, he(she) continues playing with this very cue until the end of his(her) inning!
Imagine running out with a shorty, LOL
Imagine the CB on the rail surrounded by 7 balls numbered from 3-9 with the 1-ball and 2-ball outside of the enclosure.
If confronted with the above situation, and the no-jump-cue rule, are you just going to pick up the CB and hand it to your opponent ?
A player must make a shot, i.e. drive the cue ball with the stroking motion of his cue. Trying to pass turn in a manner you described is unsportsmanlike conduct, under official rules of play.
Hence, even in such a situation a player is expected to make a move, as if playing chess. Change the position of the balls, even slightly. In case both players don't wish to disturb the position due to risk of losing the rack, three turns at the table with no obvious proceeding to the end of the rack results in a stalemate. Again, see world rules for this one.
