Ask the experts, November 2004

You're pone at 115-106*, and get dealt A 3 5 6 J K. Needing six points to win, what do you keep?

Dan Barlow:

I need six. If I keep the flush, even if I cut one of the four cards that won't help me (7, 10, Q, K), I still win if I cut the right suit. That gives the flush an edge over keeping the 5.

John Chambers:

In this situation as the non-dealer I would keep 5-6-J-K. I wouldn't even worry about discarding the A-3 to your opponents crib. After all there are 9 of 13 cards which can help your hand. And if you don't get the cut you can possibly peg the two points you need.

DeLynn Colvert:

Gotta go with the flush. The pegging deception will be worth anything I give up by relinquishing the 5.

George Rasmussen:

Since I'm only six points from the win, I retain 5-6-J-K. There are 32 cards that will give me the six points (4-4-4-4, 5-5-5, 6-6-6, 7-7-7-7, 9-9-9-9, 10-10-10-10, J-J-J, Q-Q-Q-Q and K-K-K). By the way there are also 32 cards which would put me out holding the 3-5-J-K (2-2-2-2, 3-3-3, 4-4-4-4, 5-5-5, 7-7-7-7, 10-10-10-10, J-J-J, Q-Q-Q-Q and K-K-K). If I miss one of those card however, I believe I have a slightly better chance to get a peg or two by leading the J. If dealer puts a 5 for 15-2, I can pair the 5 with no chance that dealer can peg out from 106*. The 6 will prevent the drop of the remaining 5s for a pegging coup. If dealer puts an x on my J lead, I have a chance to score a run or close the count at 30, and I'm still holding 5-6 with dealer having the next lead.

Michael Schell:

Sometimes it's faster to count the losing cuts. Reckoning from the top down, 5-6-J-K flunks on a wrong 8, 3, 2 or A (twelve total) and gets to the stinkhole on the right 8 or 2. 3-5-J-K flunks on a wrong 9, 8, 6 or A (also twelve), getting to the stinkhole on the right 9 or 8. The flush does a little better since it includes the J and thus gets at least six on any matching cut. Thus it loses only on a wrong K, wrong Q, wrong 10 or wrong 7 (eleven total). It also seems a bit more likely to peg two points. However it means tossing 5-K to the crib, a difference of 2.3 points compared to tossing A-6. I suspect that'll count for more in the long run, so I'd keep 3-5-J-K here, though it's probably close.

I prefer 3-5-J-K to 5-6-J-K because the toss is a little safer and because two-card magic elevens are generally awkward in pone's hand. If I blow the cut, I'll lead the J, which will likely keep dealer's 9 off the table, thus increasing the chances of catching a 5 or even a 2 or 3 instead — hence the preference over leading the K.

Phyllis Schmidt:

I keep 3-5-J-K, hoping for a few pegs or a cut to go out without having to peg.

Peter Setian:

Strictly counting cards — if you can do so fast enough during a game — and considering pegging probabilities for six points, I would keep the A-3-6-J flush. This hand has the most cuts for six points, and like most flush hands, a good chance at pegging the two points (if necessary) when leading the J. Only 11 out of 46 cut cards won't give you six points.

HALSCRIB:

Gosh, how to weigh the offensive potential of pegging and hand count, and how to balance offense in general against the defensive value of keeping dealer short in case I don't get a cut? Let's roll some numbers:

Keep  Toss 

  Average  
hand

  Pegging  Offens
Value
Net (pone/dealer)
A-3-5-6  J-K 5.13   -0.74 (2.02/2.76) 7.15
A-3-6-J flush  5-K 5.52   -1.18 (1.52/2.70) 7.04
3-5-J-K A-6 5.43   -1.27  (1.43/2.70) 6.86
5-6-J-K A-3 5.43   -0.93  (1.89/2.83) 7.32

The surprise in the lot is A-3-5-6, worth only two points going in, but guaranteed to improve to at least four points after the cut. In fact, it wins outright on an A, 3, 4, 5, 6, 7 or 9 cut and gets to the stinkhole on a 2. That's not as good as 5-6-J-K, which wins outright on any 4, 5, 6, 7, 9 or ten-card, and I don't think the extra pegging potential of the maverick A-3-5-6 hand will quite offset the difference. A 3 6 J rates a little lower on offense, so I don't even need to consider whether tossing 5-K is justified at this score (though I'm inclined to dismiss defensive considerations altogether here). 3-5-J-K rates lower still.

On balance I'll go with 5-6-J-K, planning to lead the J if I blow the cut. The humans might consider that a boring choice, but I'm not paid to worry about aesthetics.
