Nack (previously) wrote: "Slotting the 5pt tends to be better than slotting the 7pt (examples of both appear at the above link), but in this case slotting the 5pt is clearly worse. The reason is that after Blue plays $ (Slot, 13/8 6/5), ALL of White's aces hit on the 20pt and either cover the 4pt or hit a second checker. By contrast, after Blue plays d (down, 13/7), it is with fewer than half of her 3s (43 33 32) that White is much better off hitting on the 18pt than playing on her own side of the board."

I'm a little confused here. First of all, I think you switched d and $ in your discussion above. Secondly, Michael's rollout was an XG rollout; do you mean that you'll do a GNU rollout and post it?

I may have to stop posting before I've fully woken up (been making too many typos lately). As you suspected, I transposed the $ and d plays in my notes. I've switched them above (red font) to be as intended. It should make sense now. :)

At the time, I thought Michael's rollout was with GnuBG. Clearly it isn't, so (fortunately) I aborted my own (pledged) XG rollout before it got far along.

Finally, I would have expected you to compare 13/7 with 11/5, rather than with 13/8 6/5. Do you think that 13/8 6/5 is better than 11/5?

I didn't expect there to be much difference in value between the two 5pt-slotting plays (A = 11/5, and $) -- and indeed there isn't. I chose $ as the representative 5pt-slotter only because IMO it more closely resembles d conceptually. Both plays in my comparison ($ and d) leave a blot on the 11pt (and supplementally end up with the same number of checkers on the midpoint); that seems more relevant to me than the 8pt/6pt distribution.
