You're pone leading 100-96*. What's your keep from 5-6-7-7-8-J?

Dan Barlow:

If I try to win now by saving 6-7-7-8, I have a 20% chance of getting 20+ points and those percentages are even lower if dealer is holding any of the cards I would need. How do those odds compare with the chances that giving dealer 5-J would be just what he needs to move 25 holes in two hands? I'll leave that to the bot. All I know is I don't feel comfortable when my opponent is dealing needing 25, but he often doesn't quite make it. If it were 23 or 27 it would be an easier decision. Here I'm keeping 5-6-7-7.

John Chambers:

You have two options in this hand. You can keep the 6-7-7-8 or 5-7-7-8. If you choose to keep the 6-7-7-8 you have a 20% chance of getting the cut and winning the game. If you keep 5-7-7-8 and play defensively you have around a 50% chance of winning. To put yourself in the best position to win, my advice is that if your opponent has 25 or more holes to go, keep 5-7-7-8 and if they have 24 or less to go, keep the 6-7-7-8.

DeLynn Colvert:

You only need 21 points to win. Opponent needs 25. You must play desperation defense here. Discard the 8-J, lead a 7 and pray.

George Rasmussen:

Retain 5-6-7-7 and discard 8-J. Dealer has minimum position. You can give dealer an average hand or even better, but cannot afford much in crib. 5-J has too great a potential in crib to chance at this point in the game.

Michael Schell:

I'll keep 5-6-7-7. At this score, cutting to 15 or 16 before the pegging is fine with me (though I'll regret an A or 2 cut).

Phyllis Schmidt:

I'll toss 8-J. A 7 is not a great lead, but I would do it anyway. I have another 7, plus I know where one 8 is. Hopefully after the first play I can play away and not get caught up in a run.

Peter Setian:

I would keep 5-6-7-7. With the dealer still needing a sizable 25 points, relying on a cut for 20 or more points in my hand is too risky. Furthermore, if I do get a cut for 1516 points, I can try to peg aggressively by leading a 7. Then, with expected "pegging room", I’ll still have a good chance of pegging out on the next deal (hopefully four points or less).

HALSCRIB:

In some of my previous incarnations I may have thrown 5-J, even suited, instead of 8-J (suited shown below). Now that I know better, I will keep the 5 in the double run. Playing defense, the following table of expected hand, crib and pegging values will show why. Note that the expected offensive pegging values are shown but not included in the decision calculation:
