Ask the experts, February 2009

The score is 114-117*, and you're dealt 4 6 7 8 10 Q. What do you keep?

hide answers

Dan Barlow:

The 4 is my best opening lead, but to keep it means I sacrifice a point compared with keeping the flush. But what about after the cut? If I keep the flush I'll have enough to go out unless I cut an off-suit A, 2, 3, 4 or K (14 cards). If I keep 4-6-7-8 I'll have enough to go out unless I cut a 10, J, Q or K (also 14 cards). Cutting a J is additionally bad because it leaves dealer needing to peg only two holes. The fact that I'd like to lead the 4 must be weighed against the fact that on a bad cut, I'll have to peg one extra hole if I hold 4-6-7-8. A close call, but because I'm a favorite to have enough points after the cut, I'm keeping 4-6-7-8.

John Chambers:

This situation isn't as obvious as it may appear. If you keep the flush, there are 32 possible cards which will give you at least seven points.  If you keep 4-6-7-8 there are also 32 possible cards which will give you at least seven points. So let's look at this situation a bit closer. If you keep the flush, what do you lead? Not a 7 or 8  you would lose. A tenth card? If he pairs or 15s, he has only two more holes to get. But whichever hand you keep, there are risks. I would keep the 4-6-7-8 and lead the 4.

DeLynn Colvert:

I just had the 4-6-7-8 hand in Reno, led the 4, and was destroyed. So I would keep the heart flush, lead the 7, and escape with the 10 if the 7 is paired.

George Rasmussen:

I need seven points to win. This is a tough call. My preference is to hold 4-6-7-8 as the combined value of hand score and pegs, less the crib score, is greater. With the preferred choice there are 32 cards (A-A-A-A, 2-2-2-2, 3-3-3-3, 4-4-4, 5-5-5-5, 6-6-6, 7-7-7, 8-8-8 and 9-9-9-9) that would benefit the hand by two points or more. With 7 8 10 Q, there are also 32 cards that add one point or more (A, 2, 3, 4, 5-5-5-5, 6-6-6, 7-7-7, 8-8-8, 9-9-9-9, 10-10-10, J-J-J-J, Q-Q-Q and K). If the cut misses the hand, as it could with 12-14 cards that do not help, I believe I have a better chance to peg the two points with 4-6-7-8. I guess a personal bias has caused me to retain 4-6-7-8 in preference to 7 8 10 Q.

Michael Schell:

Some obvious facts:

  • Either keep gets enough to go out on 32 cuts
  • 7 8 10 Q gets me one point closer if I flunk the cut
  • Like most flushes, 7 8 10 Q is an "unpredictable" pegging hand, though the benefit from this is usually on offense, and it's more likely that I'll need defense here
  • Speaking of defense, 4-6-7-8 gives me a safe lead in the 4. The flush has no good defensive lead

I'm guessing that with dealer starting at 117*, a safe 4 lead is worth one pat point. So let's proceed to some not-so-obvious facts:

  • A J is one of my "winning" cuts with 7 8 10 Q, but not with 4-6-7-8
  • If I cut a J, I'm probably screwed anyway, since dealer will only need two pegs to win

Thus 4-6-7-8 has the most legitimate cuts for 7+ points, so that's my choice. I'm planning to lead the 4 regardless of the cut.

Phyllis Schmidt:

I can see no reason not to keep the heart flush, holding one more point.

Peter Setian:

I certainly don't want to get stuck in a pegging duel. I would say the odds are better to keep the flush and lead the Q (not the 10). If the dealer plays a 5 for 15-2, then play the 8 and hope the dealer must play two cards for a go. If a count higher than 15 is made, I'd try to make the count 26.

HALSCRIB:

Some background for the geeks: in end-games where I am at 111+ as pone (win zone), I compute my expected hand and peg values, and ignore discards. In addition, I use lookup tables for the probability of dealer pegging out when dealer is at 115+ (out zone):

Keep  Toss        Average 
hand:
  Pegging      Dealer
% peg out
Net  (pone/dealer) 
4-6-7-8     10-Q   6.39   -1.28 (1.57/2.85)   36.2
7 8 10 Q     4-6   6.70   -1.41 (1.70/3.11)   42.4

Although the flush increases dealer's chances of pegging out by about 5%, in my opinion getting one point closer to home matters more.
