Die in the hole when pegging

Hi All, my wife & I play for fun down the pub & on holidays etc. We deal 6 cards & throw 2 in the box & we always play what we call "die in the hole" meaning we have to score exactly 121 or 61 on a short game (as opposed to "fly straight through" i.e. the first to score 121 or more)

So here's a scenario I'm not sure about..... Say I need exactly 2 points to win, the cards in play are at 26 with a 2 played last. I play a 2 making 28 for 2, my wife can't go so that becomes "& 1 for a go" making a total of 3. In actual pegging do I take the 2 for the pair of 2's & win OR must I total the pegging & in effect score too many?

Thanks in advance :-)
