Could you quote some examples for this?
I can’t imagine any case when a player incurs 2 penalty strokes from this Rule.

If a player should have played a ball under stroke and distance (Rule 27-1a) but instead plays the ball under e.g. Rule 26-1, he’ll incur the general penalty under Rule 27-1.
Ball dropped or played under Rule 26-1 without proof

The general penalty will be handed out every time the player uses a (more favorable) relief Rule when it’s not known or virtually certain that the ball is lost because of Rule 18-1 (ball moved by an outside agency) or is lost in a condition covered by Rule 24 (obstructions) Rule 25 (abnormal ground conditions) or Rule 26-1 (water hazards)

In these cases the player should have played a ball from the previous spot, and if he plays a ball under any of these Rules instead, it’s played from a wrong place (Rule 20-7).
If it’s a serious breach, the error must be corrected.

(Boring, I know, but you asked :-))

RulesDoc,

Thank you very much for your reply.
I understand it now.
I always thought that in all these cases a penalty is from R.20-7c.
It is unbelievable that I missed this passage from R.20-7c:
If a competitor makes a stroke from a wrong place,
he incurs a penalty of two strokes under the applicable Rule.

By the way – the Rules are boring? Impossible :)

... and don’t forget this one:

20-2c/1.5 Ball Rolls Toward Hole When Dropped at Spot from Which Previous Stroke Played
Q. A player is required or elects to play his next stroke at the spot from which his previous stroke was played. He is able to identify that specific spot by reference to the divot hole which his previous stroke made. He drops a ball immediately behind that divot hole. The ball rolls nearer the hole than the spot from which the previous stroke was played, but not more than two club-lengths from where it first struck the ground. What is the ruling?
A. Rule 20-2c(vii)(a) requires a ball to be re-dropped if it rolls and comes to rest nearer the hole than “its original position or estimated position … unless otherwise permitted by the Rules.” The original position is the spot from which the previous stroke was played. Since the dropped ball rolled nearer the hole than that spot, it must be re-dropped.
However, in many such cases the player cannot determine exactly the spot from which his previous stroke was played. In those cases, the player has satisfied the requirements of the Rule if he uses his best endeavors to estimate the spot. The estimated spot is treated as the specific spot (see Rule 20-2b) and the ball must be re-dropped if it rolls nearer the hole than the estimated spot.
The same principle applies if the spot where a ball is to be placed is not determinable and the player is required, under Rule 20-3c, to drop the ball as near as possible to the spot where it lay.

Rip –
I gave the general gist of the matter.
Plenty of other examples still out there.

That’s what the OP asked for, examples…

Rip,
Thx for your replay, but I can’t see any relationship between your example and my question.
Where is 2 PS from R.27-1 ?

If I understand it correctly, 2 stroke the general penalty exactly from R.27-1 applies only in these cases when a player plays his ball from a wrong place after his ball isn’t found or identified within 5 minutes or his ball is out of bounds. Like in D.27-1/3.
Isn’t it?

Rip,
Thx for your replay, but I can’t see any relationship between your example and my question.
Where is 2 PS from R.27-1 ?

You’re right. 2 PS for having played from a wrong place, not for a breach of R. 27-1, like in D. 26-1/3.7.
