Ask the experts, February 2010

You're pone leading 85-68*. What do you keep from 2-3-5-9-10-J? Would it matter if skunks count?

Dan Barlow:

I keep 5-9-10-J. I don't like tossing 2-3, but a 14-hand would pretty much assure victory and improve skunk possibilities. Would it matter if skunks count? Unless I missed the news flash, skunks do count. I'd be more inclined to break up this hand if I were way behind rather than way ahead.

John Chambers:

I would keep the 5-9-10-J. In most situations it wouldn't matter what position you are in. If you want to skunk someone you need to "go for it". If things are going good, the worst that could happen is your opponent will get a good hand but only 4 in the crib. You will get to hole 92 or 93 as dealer. If things aren't going your way you will still get to hole 92 or 93 and your opponent still has a lot of ground to make up.

George Rasmussen:

I would retain 2-3-5-10 and toss 9-J. If skunks mattered (especially so if I needed a skunk win to qualify in a major tournament) I would toss 2-3, retain 5-9-10-J, hope for a starter card of 10 or J, and a crib score of four points or less.

Michael Schell:

Dealer starts the deal -2 while we're +25. Ignoring skunks, it's a classic choice between playing on with 5-9-10-J, hoping to shoot ahead to the next positional hole before our opponent can get there, or playing defense with 2-3-5-10 or 3-5-10-J, banking on our opponent's inability to make up that two hole positional deficit. Now the next positional hole is 11 points away at 96, and 5-9-10-J averages a little less than ten points (two more than a median hand), so there's better than a 50-50 chance of getting there if I hold aggressively. But in general I think it's better to play to your strength and away from your opponent's when facing this kind of dilemma, and since my opponent is already two holds short, I think a more defensive approach is warranted here. The nice thing about 2-3-5-10 or 3-5-10-J is that I'm still keeping open the option of pegging aggressively if I do get a favorable cut for 8+ points.

9-J only gives up ¼ point more in opponent's crib than 2-9, and 2-3-5-10 should fetch me about ½ point more than 3-5-10-J while retaining a magic five (2-3) for pegging. So I'll go for 2-3-5-10.

Throw skunks into the mix and I need to reckon my board position relative to the next positional hole, which makes me -1. My opponent's board position is reckoned from the skunk positional hole of 66 (30 points behind the corresponding normal positional hole), which makes him +2. Clearly I'm a slight underdog to get a skunk here, and I certainly wouldn't consider keeping 5-9-10-J in that situation, but would be even more certain about keeping 2-3-5-10.

Phyllis Schmidt:

I keep 5-9-10-J. 2-3 is a gutsy throw, but I feel I must keep the most points (seven). Keeping four points isn't going to do much for me at the 85 hole.

Peter Setian:

If skunks don't count, I would decide to toss 2-3, and play aggressive to try and get every possible point in this position, having no concern about the pone's crib.

If I needed a skunk, I'd definitely throw 9-J and go for one of the many cuts for a 7-8 point hand with no direct help to the 9-J.

HALSCRIB:

Here are my calculations on my odds of winning three deals hence:

Keep  Toss        Average 
hand:
    Opponent's  
crib:
   Pegging    %
Net     Loss     Win    Skunk 
2-3-5-10     9-J   7.22   4.81   -1.15    7.7 48.1 0.4
2-3-5-J 9-10   7.48   5.24   -1.13    9.2 49.3 0.3
3-5-10-J 2-9   6.78   4.48   -1.30    6.4 44.2 0.4
5-9-10-J 2-3   9.74   7.19   -1.43   11.9 59.0 0.2

The keep that maximizes my odds of a win also maximizes the odds of a loss. However, the 5-9-10-J keep is about 10% better than any of the alternatives at a cost of a 4% increase in the odds of a loss. Having said that, in this position I am playing optimal, so my choice would be to keep 2-3-5-10 and toss 9-J. The odds of a skunk are far too remote to risk the 2 3 toss.
