Ask the experts, December 2010

At 26*-23 you deal yourself A-A-2-5-8-Q and toss A-A. The cut is a 3, and the play starts:

 Q  5  ?

Do you pair the 5?

hide answers

Dan Barlow:

Is it possible he played that 5 because he has another 5? Sure. Odds aren't favorable that there were three 5s among the twelve cards we were dealt, but they aren't low, either. There are other reasons he might have played the 5. He could be getting rid of it so he doesn't get stuck leading it later. From 3-4-5-7 the 4 was a good opening lead because if I pair he can get the two points back with his 7:

 4 (8-2)  7 (15-2)

Likewise, the 5 is a good play on my Q because if I pair it he can get the two points back with his 7. I'm pairing the 5. If he triples, I get two points back (31-2). I've lost two points, but I still have at least a Go coming. And playing the 2 or the 8 could just as easily have allowed him to peg two points.

John Chambers:

No, in this position, as the dealer, you are already about eight holes above average position. Why give up those holes to bad pegging? I would play off because your opponent could have a 20 hand. Don't help him improve his position with pegging.

George Rasmussen:

With the cut of the 3, I have six points in hand and with A-A to crib, I'm likely to have 46 points in crib since I am holding a 2 in the hand. Given that, would take the two points for pairing the 5. That might put me over 40 at end of hand. I would like to reach second street critical position zone of 4347. If I can't reach that zone, I want to be close.

Michael Schell:

I started the deal +8 to pone's -11, the cut only leaves me with six in the hand (two less than average). I probably stood to make up most of that in the crib, at least until pone played a 4 and a 5 (though I guess catching a 2 is still a possibility). I'd say the position calls for balanced play, and since I can retaliate for two points if I'm tripled, I'll go ahead and pair the 5:

 Q  5  5 (24-2)  5 (29-6)  2 (31-2)

If I do get nailed, I'll blame it on DeLynn Colvert's admonition that pone's second card is usually the safest to pair (grin).

Peter Setian:

Absolutely Not! Dealing from a conservative board position, I'd play the 2 and make the count 21. I cannot get stuck in a run for the pone, nor will I get caught with the 5 at the end, like::

 Q  5  8  2 (30-1)    4  5  6 (15-6)

I'm doing all I can to keep the pone from getting pegging points in the event they have a better than average hand.

REX:

Yes, I pair the 5. In my analysis I consider all possible holdings pone could have (all 1820 of them). The Top Ten most frequent (refactored, and sorted by frequency of occurrence) are as follows. Note that only one of them includes a second 5:

Hand         Frequency
4-5-6-K 7126
4-5-6-6 6543
4-4-5-6 6396
4-5-6-7 4126
4-5-6-9 3759
4-5-5-6 3560
3-4-4-5 2939
3-3-4-5 2739
3-4-5-6 2629
3-4-5-K 2409

By pairing I increase my overall winning changes by about 5% and reduce my losing chances by another 5% for a net gain of 10% compared to the other choices.
