Who will win the inaugural event?
Will Jessica Korda defend her title?
There is no Rule that would restrict a player from carrying both right and left hand clubs in their bag. Rule 4 does limit the player to starting the stipulated round with not more than 14 clubs.
I would not consider your actions as building a stance. However, by using your feet be careful not to move anything that is embedded, such as rocks. Also be aware that this action is not permissible in a bunker or water hazard. Under these circumstances, a favorite expression of mine comes to mind, “avoid the appearance of evil”.
No. The general rule of thumb would be that, should a player create irregularities in the bunker prior to playing from that bunker, the player would have to deal with those footprints. Should the player repair any damage prior to playing he would be subject to penalty under Rule 13.
Unfortunately you incurred a two-stroke penalty for playing from a wrong place (see Rule 20-7). The good news is that it is not considered a serious breach that could end up with a disqualification penalty if not corrected.
When you dropped a ball on the green side of the hazard you dropped a ball closer to the hole than the point where the original ball last crossed the margin of the hazard. (See options under Rule 26-1). When you played the dropped ball you played from a wrong place. Normally when a ball is played from a wrong place the player incurs a penalty of two strokes and must continue the play of the hole. Unfortunately in your case you committed a serious breach, (see Note 1 at the end of Rule 20). By not correcting your error, you would be disqualified. For proper procedure see Rule 20-7c.
