I can't believe Olsen's drop above.
Sure, it's a money drop. But with such a deficit,
and on a high cube, you've got to take a bit deep.

Four checkers removed is quite a few and we do have
an open point to aim at.

It's three checkers not four, but XG agrees with you.

Thanks. I saw that I miscounted the checkers off immediately after I'd posted, but it still looked like bad play.

I never thought it was a hold, though. I saw it as RD/T.
Fancy passing a no-double, at that rarefied level!!

The players are apparently friends and they chat constantly about the plays during the match.
However, it didn't occur to either of them to question this cube action.

I think the players have very similar abilities and are both Giants or near-Giants so it
isn't one of these skill-diff things.

Of course, Jason may have thought "It might not be a double and it's an easy take but
he might wrongly drop."

Olsen did make the 2022 Giants list and the BMAB gives his
current PR as about 3.7 (on the high side for a Giant). Jason
Pack's PR is listed as about 5.0 and I don't think people would
call him a "near-Giant." But I think you're right that the skill
difference is not large enough to justify any major deviation from
what either player would play against an equal opponent.

This leads to an interesting (to me) ambiguity.
Who has the higher tennis ranking among Chris Eubanks and Jannik Sinner?

Nobody would refer to Pack as a near Giant and 1.5PR is clearly enough under the right circumstances to adjust one's decisions.

As for Eubanks/Sinner, I don't get the interesting ambiguity. Sinner has the higher ranking I'd assume no matter how you mean it.

Was this post supposed to say something
about the same Kit Foolsy, (the 8 feet tall
gamblegammon giant book peddler), who
had said that "there are 21 possible dice
rolls at every turn"..?

Did he have a math PHD like Tim also..??

In RGB, Tim's "21^7 < 2^32 < 21^8" "math"
will be as familiar as "e=mc2" for you, the
pack of sick dogs of gamblegammon and
will surely be Tim's epitaph... ;)
