Score 108*97. You kept 7899,
tossing yourself 4K. The cut is a
7 and pone leads an 8.
What's your play?

Dan Barlow:
Keeping him from pegging three or four will take some luck if he
has 20 or 21. Half the hands that would give him 20 or 21 don't
include a pair of 8s, so pairing the 8
isn't a bad play, especially as it prevents a run, at least for the
moment. Odds are heavily against both of us having 20+, so I prefer
to concentrate on keeping him from pegging eight if he has a 16 hand
(6789, 6899, 6889
or 6689). In each of these cases, playing the
7 is disastrous. Playing the 9 could
be bad (if it gets paired). Pairing the 8 is safe if
he has three of these hands, and I'm not quite dead even if he pairs
my 8 with 6889. So, I pair the
8. My guess is that he led that 8 just
to throw a scare into me, and his hand is 3448.
John Chambers:
In this situation your goal is to keep your opponent from getting
too far down on Fourth Street. You want to keep your opponent far
enough from going out so you have a chance to count your hands. My
first thought if my opponent leads an 8 is that he
has another and wants to peg. Your opponent must have 7s
and 8s. I would play a 9. If your
opponent pairs your 9 then your opponent will get two
for the pair plus a go or 31. If your opponent plays a 7
for 243, you can play your seven for 314. If your opponent plays
another 8 for a count of 25 it could be a go or 31.
Because of your opponent's lead and the cards in your hand, I
believe playing the 9 is the safest play.
DeLynn Colvert:
Your opponent needs 24 to win so I would assume a possible 16 hand.
Giving up four pegs is OK, so I would play a 9 on his
8. If you give up a run to an 8,
you'll play your 7 for 314, leaving you with a
fairly safe 9 to stop any further pegging:
^{8}^{ }_{9 }^{7 (243) }_{7 (314)}
George Rasmussen:
I like my position at 108*. It takes 24 points for opponent to
get out from hole 97. The lead of the 8 with a
7 as starter card makes me nervous, I have to admit. If
opponent's hand goes up from the eight spot, they cannot score more
than 14 points with the 7 cut. If opponent's hand
goes down, they may not need pegs in order to score 24 and win the
game by first count. I would like to know early which direction the
hand goes. So I will play my 9. If opponent plays a
7 for a count of 24, I pair the 7 and
close the count with 31 for four points. In normal play
situations with this hand to include 9s and no
6, I would pair the 8. I just can't take the
chance of giving up six pegs in the final stages of this game. In
giving up six on the play of a single card, pone may win by first
count even with a 16 point hand by picking up two more pegs along
the way.
Michael Schell:
The normal play would be to minimize objective risk by pairing
the 8. This exposes me to only two losers, worth six
points each for an objective risk of 12, ignoring goes. Note that
after being tripled, I can close out the play series with my
7, though this leaves me with the inflexible 99
to face the second play series.
Playing the 7 instead is clearly too loose,
exposing me to a pair or two different shots at a threecard run.
Playing a 9 carries a much higher objective risk of
22:
7 
2 ∙ 3 = 
6 
9 
2 ∙ 2 = 
4 
10 
4 ∙ 3 = 
12 


22 
But you can probably discount the risk of pone's 10,
since aside from flushes, a 10 would give her a
maximum of 14 points in hand. I'm guessing it's about 5050% between
the 8 and a 9. I'll leave it to the
bot to find the optimum play.
Phyllis Schmidt:
I play a 9. If opponent he has a 10,
he gets three to four holes. Against any other card, like a 7,
I can get back in the run with little damage.
Peter Setian:
Since a 24 point hand cannot be stopped, a 16–21
point hand must be guarded against. The key is: I would not make the
count 15 (with the 7), as the pone could pretty
easily peg eight points and count a more common 16 point hand. I
would probably play a 9, but could play the 8
also...for calculating all the possible regrets would take too long
during play.
But let's see: the number of regrets seem to be close either way.
Some of the pairing regrets include the pone holding 6688
or 6889. Some nonpairing regrets include
7789 or 7899. Looks like more "case"
cards are needed for the nonpairing regrets.
HALSCRIB:
The humans may complain that this hand is best suited for
computer analysis, and I concur. My calculations which include a
probabilityadjusted frequency of each of all possible hands,
reveals the following where the play could make a difference:
 6688 (loses to 8)
 6689 (loses to 7)
 6778 (loses to 9)
 6789 (loses to 7)
 6888 (loses to 7 or
8)
 6889 (loses to 7 or
8)
 6899 (loses to 7)
 7888 (loses to 8 or
9)
My results show a slight difference in loss probabilities between
playing the 8 and the 9. (Playing the
7 is worse by about 4%.) I will play the 9,
which minimizes opponent's winning chances.
Card 
Weighted Probability of Loss 
7 
12.2% 
8 
8.0% 
9 
7.8% 
If the suits of the cards were known, flush possibilities could
have been included but this would have been overkill on my part and
may add insult to injury to the humans.
