* every player is entitled and obliged to play the ball from the position where it has come to rest after a stroke, unless a rule allows or demands otherwise (Rule 13-1)
* a player must not accept assistance in making a stroke (Rule 14-2)
* the condition of the ground or other parts of the course may not be altered to gain an advantage, except in some cases defined in the rules
* a ball may only be replaced by another during play of a hole if it is destroyed (Rule 5-3), lost (Rule 27-1), or unplayable (Rule 28), or at some other time permitted by the Rules. The player may always substitute balls between the play of two holes.
Only the last of these is also recognized by the Ladies European Tour. The other event that it recognizes as a major is the Evian Masters, which is not considered a major by the LPGA (but is co-sanctioned as a regular LPGA event). However, the significance of this is limited, as the LPGA is far more dominant in women's golf than the PGA Tour is in mainstream men's golf.
