Would it matter if skunks count? |

Dan Barlow:
My chances of skunking someone who needs 19 holes and has three
hands and two pegging sequences to do it are not so great that I
would base my toss on whether skunks count. I keep 2-3-7-8.
This guarantees four points (more, if the cut is anything but a
ten-card). The only other way to assure four points is to toss
7-8, but that's much riskier than tossing J-Q.
John Chambers:
The dealer is at hole 72 which is a couple of holes better than
average position. On average, the dealer will beat the skunk. The
non-dealer is at hole 90 and needs to get to at least average
position (hole 96) on fourth street for his three counts. I would
keep 2-3-J-Q. Remember, over 30% of the deck is tenth
cards.
George Rasmussen:
I will keep 2-3-8-J and toss 7-Q.
With the dealer at hole 72, I can't chance the 7-8
discard to hold four points even though many cuts will help a
2-3-J-Q hold. Based on my empirical data, 8-Q
has a lower crib score than 7-Q. Even so, I will keep
the 8 in preference to 7 as it offers
a chance to close the count at 31 because of the presence of
3-J in the hand. With me at hole 90, it would not matter
whether I was playing for a skunk or not. If I'm at hole 95, I would
retain the 2-3-J-Q even though it's still unlikely
that I would score a skunk.
Michael Schell:
I start the deal +4. Dealer is technically -24, but since he's
only two points past the last positional hole, I'm not ready to give
up on defense here and go all in with 2-3-J-Q.
There's still a chance that I could win on the back end even with
poor cards here, especially if I toss 7-Q or
8-Q to the crib. With 2-3-7-J or
2-3-8-J, I still have several shots at getting into at least
marginal position on a favorable cut, and leading from a magic five
is good from both an offensive and defensive pegging perspective
(the latter if I get a bad cut). Since 8-Q is
microscopically safer in
opponent's crib than 7-Q, I'll go with
2-3-7-J.
Note that if dealer was several holes further along, say at 80*,
then I wouldn't bother with defense, but would just keep
2-3-J-Q.
A skunk is unlikely here, but if I really needed one, I'd
definitely discard defensively since dealer is already +6 to foil a
skunk. The pertinent skunk positional hole is 66, which is 30 points
behind the normal Fourth Street positional hole of 96.
Peter Setian:
I would throw J-Q to maximize the chance of making
a five to seven point hand, as I envision the cut cards from
A through K. A 10 point hand may not be
necessary for a good dealing position next hand —
certainly not enough to take a chance with tossing
7-8 and possibly losing the game with a middle card
cut. (If the crib is large due all high cards with the cut, I have a
better chance of some peg points.)
If skunks count, I'd still play the same.

It's time for younger brother to take over the shop from sibling
HALSCRIB and show both the humans and the old-timer bots how to do
things. Here's the situation as I see it.As usual I, REX use my

Notice that the 2-3-J-Q keep
(7-8 toss) gives us a 15.1% chance of winning on the
next deal (with a 1.6% chance of a skunk) and a 71.3% chance of
winning on the deal after that. Nevertheless, in positions like this
I play to minimize dealer's winning chances (the percentages in red
above). And that means keeping the prudent 2-3-7-J
instead. The chances for a skunk are virtually the same as the
2-3-J-Q keep.
