Dan Barlow:
I keep 5-6-7-7, guaranteed to improve on any cut. I'll
settle for one 5 in the crib, as 24 cuts will leave me with
a measly six points if I save 2-6-7-7. True, most of those
24 cuts will go nicely with a pair of 5s in the crib, but
whenever I toss myself 5-5, my crib turns out to be
5-5-2-7, with a 4 cut.
DeLynn Colvert:
I always discard the 5s to my crib. The 2
in the hand is an "out" card in case the pegging gets sticky. And you can
still hit a sixteen hand with the right card, plus the enormous advantages
of a huge crib with two 5s!
George Rasmussen:
Retain 5-6-7-7, discard 2-5 to own crib,
and match suits if possible. At one time, I would have advised discarding
5-5 from this hand. The 5-5 discard averages
8.821 to own crib. Because of the high average value of the 5-5
discard and a mere two-point sacrifice in the hand, it would seem that the
combined values would exceed the crib/hand values of the 2-5
choice. I have simulated several hundred hands with random deal to
opponent — and appropriate discarding to crib dependent on hand
composition — and in no case has the 5-5 emerged the
leader. In the most recent simulation of 100 hands, the 5-5
discard to the crib scored an average hand of 8.42 and an average crib of
8.82 for a combined total of 17.24. The 2-5 discard
resulted in average hand of 11.62 and average crib of 5.71 for combined
total of 17.33. In this case, the strength of the double run for eight and
a guaranteed two to the crib offsets the higher value of the 5-5
to crib. Have also used this example in class-room with ten boards in use
and attained the same results. Might have had a different response if the
cards had been 2-5-5-6-6-7. Let's try that one sometime!
Michael Schell:
2-6-7-7 gets a slightly higher expected average than
5-6-7-7. But hands with a 5 or a magic
eleven in them typically peg about ˝ point
better than hands that don't. And besides, I always seem to get a
4 cut when I toss 5-5 from hands like this.
So I'm keeping 5-6-7-7. Here are the numbers:

If I needed more defense, I'd keep 2-6-7-7 to give me an
out card on a 6 or 8 lead. But at this score
I'm +4 while pone is -7, and that calls for cautious offense, at least
until I see the cut.
Phyllis Schmidt:
Keep 2-6-6-7. It's your best chance to catch up and get
into a better position.
Peter Setian:
I would throw the 5-5. First, I think this discard
optimizes both hand and crib combined. Second, given the nice cards and
board position, the dealer should clearly stay away from any pegging
exchanges. Keeping the 2-6-7-7 will guard against being
"stuck" on a 6 lead.
HALSCRIB:
I may be wrong about this, but I don't think 2-6-7-7 is
that much better on defense. If pone has mid-cards, you're going to have
to mix it up with her no matter what you keep — the 2 only
forestalls it for one card. Still, you do have a little more
flexibility than you would with 5-5-6-7 or 5-6-7-7,
and since 5-5 does so well in the crib, 2-6-7-7
is my choice. Note that with average scoring, I expect to win with two
holes to spare on the last deal while my opponent stalls at 116 as pone.
So to find the best toss I use the defensive formula of:
expected average - opponent's pegging = defensive value

HALSCRIB is widely regarded as the world's strongest computer
cribbage player. Its opinion was solicited using a special analysis version
of the program. Since HALSCRIB only speaks binary, its thoughts have been
translated into English by Michael Schell and its creator, Hal Mueller, a retired mathematics professor and eight-time ACC tournament winner.
