It's a pretty easy lesson. Regardless of how you play it, youre up 24 pips after the roll. If you dont hit and he rolls 5-5 you might feel a bit silly, but thats 1 number in 36 whereas if you hit, he has at least 13 return shots at the blot on the 3 point and maybe more depending on how you play the 4th 6. Playing 13-7 4 times lets you claim an easy point early in the match.

Now, let's assume you trail in the match 4-3 to 5, Crawford. You can certainly make a much stronger case for hitting since a gammon wins the match for you. I still think I'd play it 13-7 (4) over the board.

As a final note, and to illustrate the difference between match and money play, in a money game playing 13-7 (4) is automatic since the cube is in the middle and gammons arent an issue.

OK, I fess up and say I played the blunder too!   Yes  I see the logic in playing the safer way, tho, and maybe I'll remember it.   laugh

Thanks for all the good comments, guys!   Wink

If sox is brave enough to say that she played the blunder, I have to say I played it too. I tend to play over aggressively at times and moving the 4 pieces is a much smarter move. There. I feel better now.

PlayBunny misses the point, which is that unless White rolls 6-6 or 5-5, the game will end with a cube turn, so the wolf can slaver all that he likes, but he isn't going to be attacking much! After 5-5, Red won't be good enough to double. After 6-6, he will have a double though, because the last White checker will still be blocked and Red will have some attacking and racing chances as well of course. White needs to play 6-6 well though and that probably means making her 1 and 2pts, even though it wastes pips. Doing that will give her a four point board and thus deter Red from the more extreme blitz plans.

This position, from a five point match today, illustrates a similar theme, except that the cube has already been turned. Can you find Black's best play for 3-3?
Black leads 2-0 to 5.

13-10 (2), 9-6 (2). Same theme except gammons are significant for both players. Black is hugely ahead in the race, just needs to clear safely to go 4-0, Crawford.

While 8-5 (3), 5-2 is tempting, it farts squarely in the face of clearing black's midpoint, which is his biggest obstacle. Black doesn't want a hitting contest here, he just wants to win quietly.

When you're leading run safely to home and when you're trailing fight for the last man. Smiley Simple and common rule which is rarely wrong in basic holding and running games.

yes this is of course (!!) the best play and anything else is a big blunder. My opponent actually played the interesting 8/5*/2, 9/3, an "attack with not much immediate risk" sort of play which I didn't consider at the time, but it doesn't deal with the biggest problem which is as NIHILIST points out, the clearing of the midpoint.

Well, you can call it missing the point if you like but I think of it as focusing on the checkerplay, which is my forte. I make no claim to be an expert in the cube at this time and thus prefer to talk less about it.

The post that I made is good checker play logic and would be useful to others who tend to underplay the cube, as well as in a 1-pointer where checker play is the only consideration.

Safe play or bold play?

Red is ahead in the race (or will be once the 66 is played.)
Red has no checkers back.
Red faces no real threats.

All point to a safe play (e.g. 13-7(4)) rather than a risky play (i.e. putting a white checker on the roof and leaving a shot.
