Playoff concession: legal?

Is a stroke play, sudden death playoff a new, shortened stipulated round?  And can one player, in a two man game, concede a hole, thus accepting defeat immediately?

Point was made by generally knowledgable European TV commentator in recent 2 man playoff, on first hole, one chap went wild into bush, flopped 3rd shot, and was 3 behind other man on green in 2, and TV guy said 'that if match play hole would be conceded', implying that such concession not possible, even in stroke play sudden death. U agree?

There are no concessions in stroke play.  The other player (who going to win) still has to hole out to finalize the playoff.

The above was posted based on observation of a playoff between Jim Furyk and Brian Davis (when his backswing  touched a loose impediment in a lateral water hazard beside the green).  The head Rules official still had Furyk complete the hole.

However, I've just been reminded of Decision 33-6/3 (below) which suggests a player can withdraw or concede defeat - not quite the same as conceding strokes.

33-6/3

Determining Winner and Positions in Stroke-Play Play-Off

If there is a stroke-play play-off between two competitors and one of them is disqualified or concedes defeat, it is not necessary for the other to complete the play-off hole or holes to be declared the winner.

If there is a play-off involving more than two competitors and not all of them complete the play-off hole or holes, the order in which the competitors are disqualified or decide to withdraw determines the result of the play-off. (Revised)

Yes, so he is 'withdrawing,' which means he does not finish second and take home the winnings. He is now withdrawn and at the bottom of the table. Is this correct?

No, his withdrawing from the playoff does not affect the results for the event, other than he won't be the winner.  In a two person playoff, the person who withdraws from the playoff would finish second in the event itself.

So the other person in the playoff has to finish the hole regardless.... unless the event officials rule otherwise.

Read Decision 33-6/3 above.
