So things are pretty close up until about 70 points. Then she scored a 20-some-odd hand.
The game ended at 121-89. The last complete count was her hand and crib. I jokingly started to push the peg to 121.
As it turned out, it left her at 120 and me one point shy of the skunk mark. I resolved myself to get that one point on the play.
I cribbed a pair of jacks (yeah, like she was going to count those) leaving me with an 8,5,2,A. She set down a 4.
Knowing her as I do, the 4 was probably part of a run, meaning she probably had a 5, or a 3. Less probably a 6 or 2.
With the cards I had, I probably wasn't going to be able to low-ball enough for the 15. That meant trying to make it impossible for her to get a 15.
If I had set down the 8, that leaves it at 12. A 3 (for 15) ties up the game for her nicely.
If I had set down the 5, that leaves it at 9. A 6 (for 15) or 5 (for a pair) ties up the game nicely.
If I had set down the 2, that leaves it at 6. An improbable 9 (for 15), a less probable 2 (for a pair), or a 3 (for the run) does it.
If I had set down the A, that leaves it at 5. A K,Q,J, or 10 (all for 15) ties it up.
So, going with what I knew, I decided that the ace was my best bet. It left open the minor possibility of getting the 15 and included a card that didn't seem in her range.
Naturally she had a Queen.
So I was skunked by one point.
Looking at her hand afterwards, it turned out that I couldn't have set anything down that wouldn't have given her a point.
Nethack, the legendary game of giveth-and-taketh-away brutally, is more sporting than playing cribbage with her. I'll take my dexterity versus a wand of death over a hand with her.
edit: sed 's/89/90/' I was at 90 points, not 89.
