No pun intended, but I suspect some confusion. Would you please answer my questions?
We'll have to distinguish between a gimme by a player himself and a ball being "given" by an opponent. Which one was it?
AFAIK, the new gimme option is a button on the game screen, not a menu option. It's available only within 2 feet of the hole. What was the distance of the gimme putts?
OTOH, balls (and holes) can be conceded in matches, single or alternate shot. The "concede hole" option is in the menu. This would also explain the missing option in some situations. First, none of the party in turn of the stroke can concede their own ball. In fact, only one of the opponents may concede, which is the one having the next stroke on their ball, IIRC. The concede will be shown on all screens, did this happen?
You won two A/S matches Saturday, was it in one of these?
