At 119*-113 you deal yourself 2-5-6-8-9-Q. What do you keep? Would you make the same discard regardless of pone's score?

Dan Barlow:

I keep 2-5-6-8 regardless of pone's score. It lets me peg on anything except an A, 3 or 4. So does 2-5-8-9, but if pone leads a 4 I'll be playing my highest card. If I start with 2-5-6-8, I'll retain 5-6, giving me a possible chance to make a run that gets me out. Being left with 2-5-8 doesn't look as good for a run.

John Chambers:

As the dealer you only need two points to go out. You don't have to keep any points. Your opponent needs to peg eight points before you peg two.

Now you need to decide what to keep. How do you decide this? If your opponent has low cards you should keep the 2. If he has a tenth card you should keep the 5. If your opponent leads a 7 you have to keep the 8. So far we are keeping 2-5-8.

The remaining three cards are 6-9-Q. You don't need to keep the Q. If your opponent leads a 5 or a tenth card, you have the 5 to peg the two points you need.

Is there a difference between the 6 and 9? What cards haven't we taken into consideration? The only cards that would be a problem if lead by your opponent are A, 3 and 4. If an A is led, keep either the 6 or 9. If the lead is a 3 or 4, by keeping the 9 you have one more option of setting up your opponent or avoid a run situation. I would choose to keep the 9.

So I would keep 2-5-8-9. I would not keep the same hand in other positions.

George Rasmussen:

I will retain 2-5-8-9. Although 2-5-6-8 is about the same, the 2-5-8-9 increases my chances to score a run with the 8-9 in sequence. In situations where the game was not on the line, I would play 2-5-8-Q and discard 6-9 to my crib.

Michael Schell:

With pone needing eight points to go out, I'll play on as dealer if I'm within four holes of home. I'll keep 2-5-8 to cover a 2, 5, 7, 8 or x lead. Between the 6 and 9, I lean toward the 6. The 5-6 might get lucky enough to trap a 4 or 7, whereas 8-9 could trap a 7 or 10. But if pone has ten-cards (like a 10), I expect my 5 will likely prevail anyway. So it's 2-5-6-8 for me.

When I'm at 119* or 120* I almost always try to peg out, regardless of pone's score. With a 6-8 available to win on any mid-card lead, I can't think of a situation where I'd want to retain the Q as an out card. And if pone was within a couple pegs of home, I'd prefer the 6 to the 9 as a response to a 3 lead.

Phyllis Schmidt:

Regardless of how close pone is, I would keep 2-5-6-8. I need to match a card of opponent's, or keep two cards close together to get a run at the end.

Peter Setian:

I'd keep 2-5-6-8, simply for the most variety of getting two points on the lead card. I would probably keep the same four cards regardless of pone's score. Maybe I'd hold the 9 instead of the 6. But I'm keeping enough of a variety where I can hold the opponent from pegging, if I cannot peg two points myself.

HALSCRIB:

In an out zone position (where one or both players could peg out) my keep is based on the probability of either or both players pegging out, and subject to HAL counting out or over. These probabilities are stored in lookup tables. The following table presents the probabilities for pegging out with this hand at 119*-113. For comparison purposes, numbers for 119*-119 and 119*-120 are provided. They include the probability of a J starter.

Keep  Toss        119*-113      119*-119      119*-120
  % Win    % Loss   % Win    % Loss   % Win    % Loss
2-5-6-8     9-Q   94.4 0.0   89.6 5.2   85.2 14.0
2-5-8-9     6-Q   96.0 0.0   90.8 5.6   89.2 10.4
2-5-8-Q     6-9   95.2 0.0   85.2 8.0   82.0 17.6

In all cases, 2-5-8-9 wins a little more than the alternatives, so it's my choice regardless of pone's score when I'm at 119*.
