Dan Barlow:

I toss the 7s. Odds are so strongly in favor of opponent going out if I don't, that I have to keep the holding that gives me the best chance of improving my hand.

John Chambers:

If I only have seven points to go and have first count, I am going to keep A-4-J-Q. Over 30% of the deck are tenth cards. I have the four tenth cards plus an A, 4 or 5 to give me points and the game. That's 7 out of 13 ranks. I'll take those odds.

DeLynn Colvert:

Hold A-4-7-7, tossing the J-Q. You are almost certain to score on the cut card: an A, 4, 7, 8, 10, J, Q or K will give you at least six, needing a single peg to win.

Lead the 4, backed up by the 7, scoring on any face card response.

George Rasmussen:

Got to play the numbers in this case. There are 24 cards with the potential to put me out by holding A-4-J-Q. Those are A-A-A, 4-4-4, 5-5-5-5, 10-10-10-10, J-J-J, Q-Q-Q and K-K-K-K. I surely don't like sending 7-7 to dealer's crib. Even so, if I hold A-4-7-7, there are 16 cards that will put me out. Those are A-A-A, 3-3-3-3, 4-4-4, 7-7 and 8-8-8-8. It's true that any starter card of ten-point value gives me six points if I'm holding A-4-7-7. But it's difficult to peg in those final holes on Fourth Street, and there is no tomorrow. I'll go for it and retain A-4-J-Q!

Michael Schell:

Since I'm already within three point of victory whether I keep A-4-7-7 or A-4-J-Q, I'll adapt my endgame count, and only look at cuts that improve my holding. A-4-7-7 wins on an A, 3, 4, 7 or 8 cut, and gets to within one on a ten-card. That's

(16/1) + (14/2) = 23

In other words, it's about a 50-50% shot (as there are 46 possible cut cards). A-4-J-Q wins on an A, 4, 5 or ten-card, and gets within two on a right 2, 3, 6, 8 or 9. That comes out to:

(24/1) + 5/3 = almost 26

Although A-4-J-Q does a trifle better in the endgame count, chiefly due to its eight more outright winners, there are a couple of mitigating factors. First, dealer is twelve holes out, which makes him a favorite to go out, but certainly not a sure thing. If I flunk the cut, I'm more likely to survive to the next deal if I've tossed J-Q than 7-7. Second, A-4-7-7 is likely to be a better pegging hand in this situation, with my opponent expected to play desperation defense. If I lead from the magic five, dealer won't expect the 7s, and vice versa. I'm guessing that these two factors make up for the reduced number of winners, so I'm tossing J-Q, not 7-7.

Phyllis Schmidt:

A-4-7-7 and A-4-J-Q are each worth four points. I'll take my chances with A-4-J-Q, as J-Q is definitely safer in the crib than 7-7. The the only advantage in keeping J-Q is if a face card is cut.

Peter Setian:

I would toss J-Q. I'm losing out on the 5 cut, but gaining on the 3 or 8 cut.

My plan would be to peg a go (or more) with a six-point hand by leading a 7 (looking for 17 and playing the second 7 for a count of 24).

HALSCRIB:

I need to play offense here and keep the hand that maximizes my hand and pegging points. I think most of the humans will agree with me on this one. On this basis I come up with the following:

Keep        Toss    Adj. Average
Hand
   Off.
   Pegging
   Total
A-4-7-7 J-Q 5.65 1.28 6.93
A-4-J-Q 7-7 5.67 1.39 7.06

A-4-7-7 is good, but A-4-J-Q is a little better, so off go the 7s.

Note that I have a special way of calculating averages in the endgame, which takes into account that in this particular case, I can't score more than seven points.
