Simple Example

In Response To: Example for clarification (Maik Stiebler)

Just this past weekend in PGH during my doubles match there was a racing cube where we were doubled and both myself and my partner knew it was a technical clear take. UBK wanted to take without question, thought the take was too big. I was very unsure given that I thought we had a 3 PR or 100 elo difference in the match. The take ended up being about .120 I think and I would have lost no sleep whatsoever if we would have dropped it. MCG said at the time that he probably would have passed it also.

Below is a simple race, the first with a regular MET and the second with the jacobs100 loaded. A mundane example and if you can't imagine passing a meager 0.144 well then ... you have issues.

The score (after 0 games) is: gnubg 0, Stick 0 (match to 7 points)

Move number 2: Stick on roll, cube decision?
