Left handed and right handed

Please refer to Gerald's posting on Friday 20 March 2009.
Golf is a gentleman's game and must be played fairly. So check the Decisions for this title which I have pasted below.

24-2b/17 Obstruction Interferes with Abnormal Stroke; Abnormal Stroke Reasonable in Circumstances
Q. A right-handed player’s ball is so close to a boundary fence on the left of a hole that the player, in order to play towards the hole, must play left-handed. In playing a left-handed stroke, the player’s backswing would be interfered with by an immovable obstruction. Is the player entitled to relief from the obstruction?

A. The player is entitled to relief since employment of an abnormal (left-handed) stroke is necessary in the circumstances — see Exception under Rule 24-2b.

The proper procedure is for the player to take relief for a left-handed stroke in accordance with Rule 24-2b(i).

The player may then use a normal right-handed swing for his next stroke. If the obstruction interferes with the swing or stance for the right-handed stroke, the player may take relief for the right-handed stroke in accordance with Rule 24-2b(i).

24-2b/18 Obstruction Interferes with Abnormal Stroke; Abnormal Stroke Not Reasonable in Circumstances
Q. A right-handed player’s ball is in a poor lie. A nearby immovable obstruction would not interfere with a normal right-handed swing but it would interfere with a left-handed swing. The player says he wishes to play his next stroke left-handed and, since the obstruction would interfere with such a stroke, he is entitled to proceed under Rule 24-2b. May the player invoke Rule 24-2b?

A. No. If the only reason for the player to use a left-handed stroke is to escape a poor lie, use of an abnormal (left-handed) stroke is not justifiable and the player is not entitled to invoke Rule 24-2b — see Exception under Rule 24-2b.
