In a four-ball match -- that's a two-man, best ball competition like our Turkey Shoot coming up in November -- Player A has a 10-foot putt for birdie and his partner, Player B, has a five-footer for bogey, and his ball is on the same line as Player A.
Their opponents concede Player B's bogey putt, not wanting Player A to see the break from his partner's inconsequential putt. The problem arises when Player B ignores the concession and putts anyway.
Player B elects to putt despite the concession and his partner receives assistance from him in doing so. The result? Player A is disqualified from the hole. Player B's putt, having been conceded, stands as the side's score for the hole.

Putting Out After Concession of Stroke
Rule 2-4 does not cover the question of whether a player may putt out after his next stroke has been conceded. A player incurs no penalty for holing out in such circumstances. However, if the act would be of assistance to a partner in a four-ball or best-ball match, the partner is, in equity (Rule 1-4), disqualified for the hole.
