You're pone at 110-94*. What do you toss from A 8 9 J J K?

Dan Barlow:

If I knew the cut would be a 10, I'd keep 8-9-J-J. If I knew the cut would be from among a 5, 10 or Q, I'd save 9-J-J-K. What I do know, unfortunately, is that the cut will probably leave me with two or four points. So I'm playing defense. But that usually means leading a low card. Here I don't want to lead the ace and see a 10 come down when I'm holding 9-J-J. So I'll lead a J. Come to think of it, if I'm going to lead a J, I might as well save 8-9-J-J. I feel a 10 coming.

John Chambers:

Let me say up front that I would discard the A-9. You may ask, isn't the A-8 a better discard? Yes, in general it is. But this is a specific critical situation at the end of the game. You need 11 points and the dealer needs 27 points. Remember that between the play, hand and crib, the dealer averages 16 points. The only way your opponent can win from his position is to peg well, get a good hand and get a good crib. You have no control over his hand but you do have some control over his crib. In this case you want to minimize the points in his crib. If you threw the A-8 and a 6 is cut, the most in your hand would be four and you would have to peg well to go out. If you discard the A-9 and a 5 comes up, it may help his crib but it would help your hand and you need to peg only three holes.

DeLynn Colvert:

I'd toss the 9-K. Give this hand up to play defense, as any cut will surely leave you short. The A-9 is my second choice.

George Rasmussen:

Retain A-9-J-J and discard 8-K. Dealer is a hole or two short, and I hope to pick up a few points on this hand although the percentages for scoring 6+ points is not good. In this case the 9-K would be slightly lower in terms of crib average, but holding the 9 with the J-J offers a double run potential missing with the other toss. 8-K's average is .211 greater than 9-K at 3.940. Even so, my increased hand potential more than offsets this small difference on crib average.

Michael Schell:

Dealer is going in -2, and since 8-9-J-J represents my only chance at getting all the way out with my hand, with just two shots at the right 10 (and the wrong 10 getting me to the stinkhole), my first impression is that it's better to emphasize my "better" chances, meaning defense with 8-K or possibly 9-K. However, I try to apply a bit more rigor, at least when money or rating points are on the line, so let me explain how I might approach this troublesome decision if it came up over the board at the Grand National.

I'll assume that getting to the stinkhole is as good as a win with dealer this far back. Since any 10 cut to 8-9-J-J fits that bill, I'll say that this hold increases my front-end chances (those of winning the game on this deal, or else by pegging out next deal) by 9% (4/46). 8-9-J-J also gets me a shot at seven or eight points on a 7 cut, but so does a 10 cut to A-9-J-J, so that's a wash, but nevertheless I'll figure that this will win going forward ¾ of the time or 7% (3/46). So much for the front end. What about the back end, my chances of winning through defense (i.e., by counting out next deal after my opponent falls short)? Well A-K actually gives up only about .1 more than 8-K, though it has a .3 edge over 9-K. Having the A as an out card (or even a desperation low card lead) is worth perhaps ½ point defensively. So I'll give A-9-J-J about a ¾ point back-end edge over 8-9-J-J while A-8-J-J gets a one point edge. My rule of thumb is that when dealer is at the Fourth Street positional hole (96*), his chances of going out in three counts increase by 7% for each additional point he scores. I'll shade that down a little when he starts at 94*, but even the full point I'd save with A-8-J-J only adds about 6% to my back-end chances, whereas 8-9-J-J adds 9% to my front-end chances.

So despite first impressions, it looks like the aggressive A-K is the right toss, probably winning a couple more times in a hundred than one of the max-defense options.

Phyllis Schmidt:

I'll toss A-K. There's not much to work with, and it's tough to get into position to count out without some help from the cut or pegging. I would lead a J, keeping my 8-9 together, hoping to get a run on the last play.

Peter Setian:

I would toss A-8, and lead the 9, not bothered if the opponent plays a 6 for 15-2 (likely a small crib count). Furthermore, if I catch one of three cards for an 89 point hand (5, 10 or Q), I may likely be able to peg one go, and then peg out on the next deal as dealer before my opponent counts their final hand.

HALSCRIB:

There are four choices that the humans may make, and I will provide the percentages:

Keep  Toss        Average 
hand:
     % this deal      % next deal
Lose Win Lose Win
A-8-J-J     9-K   3.74   1.0  1.8   26.0 71.8
A-9-J-J     8-K   4.26   1.1  5.2   25.0 72.6
8-9-J-J A-K   4.35   1.4 11.6   25.2 72.4
9-J-J-K A-8   4.43   1.7  8.7   26.5 70.8

If I foresee only one more deal, my objective is to maximize my hand when pone, so I will toss A-8. If my objective were to not lose on the next deal, then I would have tossed 8 K and risked the unlikely flush in crib.
