INTERRUPTING
THE STRIKER The adversary must not interrupt, distract, interfere
with or offer advice to the striker except to forestall play in accordance
with Law 23. If he does so, Law 55 may
apply and the striker may take advantage of any such advice.
PRESENCE
ON COURT The adversary must not ordinarily remain on the court
when the striker is playing or move onto it until the striker's turn
has ended and, in handicap play, until the striker has indicated that
he does not intend to play a half-bisque or bisque.
