It's the first hand of the game and you're dealing. After the
cut, you find yourself holding 2-3-4-5 (no flush).
What, if anything, might you have tossed to you crib to result in this? |

Dan Barlow:
Despite a strong desire to get that 5 into my crib, I'd
have tossed 7-8 from this.
John Chambers:
In order to look at this situation fully, let's examine two scenarios.
First, in general, regardless of your position, you could have thrown
7-8 or something similar. If you had A-2-3-4-5-6
you would keep the most points with the biggest potential, namely the
3-4-5-6. If you had something like 2-3-4-5-10-K,
you would have thrown a 5-x combination. But suppose it is
at the end of the game, you are both at hole 111, and you are the
non-dealer. In this situation you would also keep 2-3-4-5
to give you one more chance to get the points you need.
DeLynn Colvert:
I might have tossed A-x hoping that the pegging
potential of the 2-3-4-5 will make up for having A-x
instead of 5-x in my crib. In general I'd discard
5-x if available and would keep 3-4-5 with a
7 or 8. Check the board and handle this with
discretion.
George Rasmussen:
This is very unusual hand for dealer to retain. First question to ask
is why am I holding a 5 in my hand for a single point when
a 5 combined with any other card to the crib averages
nearly six points, and many of those 5 combos are worth
more. I should have tossed 7-7 to my crib. It would not
make sense for dealer to hold 3-4-5-7 for five points and
discard 2-7 to own crib. Hold 2-3-4-5 for
four, and start with two points minimum in crib for combined value of six
points. The only other possibility is the 7-8 discard,
although in this case it would be preferable to hold 2-3-4-8
as those cards represent good pegging value, and the 5-7 to
crib is a good discard with an average only slightly less than the
7-8 (7-8 averages 6.44 to one's own crib and
5-7 averages 6.0). In playing those five points and assuring two
points in the crib, dealer starts with seven, which more than offsets the
difference in crib value.
Michael Schell:
2-3-4-5 is a rarely held hand for dealer, or at least it
ought to be. In most cases either the 2-3 or the 5
will perform better in the crib than in the hand. That's true for hands
such as:
- A-2-3-4-5-6, 2-3-4-5-6-7,
2-3-4-5-6-8/9/x (toss 2-3)
- 2-3-4-5-7-9 and 2-3-4-5-7-x (toss the
5 and a mid-card)
- A-2-3-4-5-x, 2-3-4-5-8-x and
2-3-4-5-9-x (toss 5-x)
- 2-3-4-5-x-x (toss 5-x or perhaps
2-3 depending on the exact ten-cards)
The exceptions come when the last two cards are mid-cards, specifically
7-8, 8-9 or a pair of 7s,
8s or 9s. These do well enough in the crib
that, coupled with the offensive pegging power of 2-3-4-5,
it's probably better to keep the four-card run together than to split the
mid-cards. For example, here are the numbers for 2-3-4-5-7-8:

Note that if you start with a 6, then the 4-5-6
combo screams out to be kept together. And with 2-3-4-5-7-9,
the 7-9 is too weak in your crib to prevail over tossing
5-7. Also note that if you plan to peg defensively, then
you are probably better off keeping a mid-card instead of the 5
to better space your hand. That's not the case at 0*-0, so if I started
with 7-7, 7-8, 8-8,
8-9 or 9-9 at that score, I could well find myself
holding 2-3-4-5 after the cut.
Phyllis Schmidt:
I must have tossed 7-7 to my crib. With any other
starting hand, I would have dumped the 5 in the crib.
Peter Setian:
The most logical discard is 7-7. Other discards like
7-8, 8-8, and 8-9 or
9-9, are debatable. In the latter three instances I think I would
throw 5-8 or 5-9. Probably the most
controversial discard is 7-8 (versus 5-7).
HALSCRIB:
Because I need to have six cards to make a discard decision, my creator
had to feed me all possible non-flush hands that include 2-3-4-5.
After calculating the expected averages and average pegging for each of
the 91 possibilities, I conclude that I must have discarded 7-8
or a pair of 7s, 8s or 9s to
have retained 2-3-4-5.
Here is some analysis. There are four broad groups of hands:
- The two extra cards are a pair
With a pair of As through 6s I'll keep a
double run. With a pair of ten-cards I'll keep 2-3-4-x.
That leaves 7s, 8s, and 9s.
As Schell notes, I get a better expected average and better net pegging
keeping 2-3-4-5 instead of 2-3-4 with a
mid-card
- The two extra cards are a non-pair both A
through 5
In this case I'll keep the double run, or else throw the pair of
5s
- One extra card is an A through 5,
the other is a 6 through K
With A-2-3-4-5-6 I'll keep A-4-5-6.
With A-2-3-4-5-7/8/x I'll keep A-2-3-4.
With A-2-3-4-5-9 I'll keep A-2-3-9. With
any other hand in this group I'll have a double run to keep
- The two extra cards are a non-pair both 6
through K
I'll toss 7-8 if available, but otherwise it
works out better to toss 2-3 (with a 6 and
anything else), 5-7 (with a 7 and a
9 or x), 5-9 or 5-x
