Title: Fibsboard Forum Match 18 Game 4 - Result
Post by: stiefnu on May 27, 2014, 10:15:09 PM
juanz rolled 64 and hit us on his 6-pt. Then the Herd rolled 5-1. It would have been a massive error to do anything other than hit, so I took the liberty of making that move, bar-19*. Then juanz rolled 55 and came in up to his 5-pt, passing us in the process. Contact was broken and the race was on! juanz then again rolled 55 and followed with 44 (to our 32 and 64), raising the prospect of an unlikely game win for him. In the end, the Herd limped over the winning line, with juanz having just two left on his ace point. One more doublet and he'd have got to post-Crawford.

So the Herd wins the match 5-0. The match file is attached.

Many thanks to all who took part, especially to juanz, who I don't reckon had the dice gods on his side.

And special thanks also to stog and ah_clem for their patient mentoring!  :yes:

   Luck based rating      61.02% favorite                38.98% favorite

The numbers tell the story.  We had +3.6 gain in equity due to the luck factor alone.  3.6 games in a 5 point match is too much for most players to overcome; add in the herd's 1.77 PR and juan never had a chance.

Impeccable cube handling on both sides of the table.

Thanks to Steve for facilitating and to Juan for playing.  I'll post rollouts of the Herd's errors and one blunder.
