for nabla

« on: September 28, 2006, 03:54:39 PM »

so nabla, you seem to be interested in doubling probabilities, here´s a question for you, a matchsituation that happend to me two weeks ago on fibs:

Doppler-Aktion?

GNU Backgammon Position ID: CgAAWAAAAAAAAA
Match ID : UQmgACAAAAAA

Code:

+13-14-15-16-17-18------19-20-21-22-23-24-+ O: gnubg
| | | O O | OOO 2 Punkte
| | | | OOO
| | | | OOO
| | | | OO
| | | | OO
v| |BAR| | 5-Punkte-Match
| | | | XX
| | | | XX
| | | | XX
| | | X | XXX Am Wurf
| | | X X | XXX 0 Punkte
+12-11-10--9--8--7-------6--5--4--3--2--1-+ X: user (Doppler: 2)

What about whites, what about blacks winning probabilities?
where is black`s minimal doubling point, where is white`s takepoint?
what`s blacks MWC with and without a double?

questions from the real life

I've tidied up your position, gumpi , (I hope I've got it right) so those unfamiliar with gnubg can have a look.

+13-14-15-16-17-18------19-20-21-22-23-24-+ o:0

X leading (2,0) in a 5pt match, ie (-3,-5), is on roll with the cube centred.
Do they have a cube and what are the relevant numbers (MWCs pre and post cube, tps etc ) ?

PS my adjusted Kleinmann is around 1.75 - so I reckon they certainly should cube and hope their opponent takes. (I doubt gnubg would!)
