Holding this hand as it increases with every cut. Liam shows that tossing 2-7 or 2-6 results with the same combined expected averages of 15.10 points (average expected hand 11.70 and average expected crib 3.40).
There is a difference with the value of the crib toss using Ras's figures: 2-7 is valued 3.78 and 2-6 is valued at 4.15. Apparently due to what opponent tosses our way? Let's see what others decide with today's hand.

I like the 5-6 here. The cut doesnt help the hand much.

I see the 2-6 option, but I'm curious to see how discarding 5-6 might pan out. Interesting puzzle Gary.

5-6 is a great toss, worth breaking up a mediocre double run like 5-6-6-7. imo. Discard pro disagrees with me by 0.3 but the odds are being pulled up by the chance of a triple run.

RAS misled thousands of crib players by instructing them in live play, class, and on video that discarding 5-6 from this hand was the way to go. Began to suspect that was not the case. So did 1,000 simulations, and holding the double run turned out to be the better choice by about a point. This was verified by queries on Halscrib, REX, and Cribbage Prof. As a result, I have dropped this hand from more recent editions of "Double Run Hypnosis". Thanks glmccuskey for reminding me to check the ACC website to see if the most recent version of that paper is posted. The high scoring 5-6 discard assures a crib on average of three points more than does the 2-7 or 2-6. The double run scores on average three points more and pegs much better for the dealer. So the double run ends up with a combined value of 1 point better. At hole 65 it's off., off., off. for me. Moving down the board is of more importance to me than playing defensively to minimize opponent score. Since paying offense pegging strategy, that means will take the 15-2 with the five spot, keeping 6-7-7 intact. If choosing defense, playing the 6 on a X lead is the correct choice, often closing the count with the 5 for 31-2.

What Rosemarie said. Same expected average but min 10 points combined.

I think its 2-6, 2-7 or 5-6?:

5-6-7-7: 8pts + 4pts (Schell: 3.93) = 12pts

5-6-6-7: 8pts + 4pts (Schell: 3.81) = 12pts

2-6-7-7: 6pts + 6˝pts (Schell: 6.63) = 12˝pts

Potential:

5-6-7-7: Improves with AAAA, 222, 3333, 4444, 555, 66, 77, 8888, 9999 + 16xXs = 46 cuts = 46/46 = 100.0% up to 12/14/15/16pts with 222, 3333, 4444, 555, 66, 77, 8888 = 22 cuts.

5-6-6-7: Improves with 222, 3333, 4444, 555, 66, 77, 8888, 9999 + 16xXs = 42 cuts = 42/46 = 91.3% up to 12/14/15/16pts with 222, 3333, 4444, 555, 66, 77, 8888, 9999 = 26 cuts.

2-6-7-7: Improves with AAAA, 222, 555, 66, 77, 8888, 9999 = 22 cuts = 47.8% up to 12/16pts with 222, 555, 66, 77, 8888 = 14 cuts.

Position:

We're ahead but as I'm 5pts short of position I'll play Offense.

Pegging:

Playing Offense I think 5-6-6-7 and 5-6-7-7 will peg better.

Summary:

2-6-7-7 starts with ˝pt more but the other two hands have many more cuts for improvement and more cuts for good/very good hand. 5-6-7-7 is guaranteed to improve and the 2-6 is slightly better to the crib (according to Schell) so I'll throw a 2-6.

At 65*-55 playing a Defense strategy for the pegging the dynamic expected averages and Win/Loss %s are:

_________________Pone's
Defense___Hand___Pegs___Crib_Total____W4 %____W5 %
5-6-7-7___11.70+(-1.96)+3.42=13.16____37.8____72.0
5-6-6-7___11.70+(-2.15)+3.45=13.00____38.4____71.8
2-6-7-7____8.52+(-2.30)+6.24=12.46____34.3____69.9

Defense_______L4 %____L5 %
5-6-7-7_______6.7_____17.8
5-6-6-7_______7.2_____18.0
2-6-7-7_______6.0_____18.0

5-6-7-7 is 0.16pt best for expected averages and is slightly better than 5-6-6-7 and significantly better than 2-6-7-7. So I'll select 2-6 to discard.

After the A cut I'll play Defense to the lead.

The analysis being done here today is just not going to happen for me in real time in the middle of a game. As far as I can tell from all this data, 5,6,6,7 is not that much worse than 5,6,7,7. I'm good with my decision.
