Here is a collection of random extrema (that I wrote down) for sessions and such.

9/06/2006 - I held 7 voids, 8 singletons, and 3 7-card suits in 27 boards.

9/28/06 - I witnessed the most duplication I've ever seen between two hands:

KT97

QJ84

AKJ

QJ6542

QT9
Counting T and 9 spots, our hands contain a total of 18 honor cards, and 9 of them are completely wasted (the hJ is probably wasted too).

10/14/2006 - I held the following hand while playing online with Noble, which is by far the worst hand I've ever seen much less held:

432

8762

862

642

11/1/2006 - I held the best hand in terms of high cards that I've ever held.

AK6

AKQ

AKT5

AJ2

Not the best 28-count in the world, but I'll take it. So I opened 2C and was sitting there contemplating how many NT to bid, when RHO chimes in with 3S over partner's 2D. This seemed like a defensive hand to me, so I doubled, but partner thought it was more of a pure penalty double and passed on

J95

J9832

QT984, so we missed a makable slam.

7/8/07 - I held arguably a better hand than that:

AKT

AK9876

If I had to assign a number to it, I suppose that number would probably be 30. We ended up in 6N making 6, when partner showed up with the cQ and the diamond finesse was on.

7/7/07 - I held almost certainly the worst cards I've ever held over 24 hands:
6 7 9 5 6 8 6 12 7 4 11 7 8 5 2 8 8 3 9 3 7 13 12 8
This comes out to 7.25 HCP, with only 4 above average hands. Normally I don't care about not having high cards, but this was also one of the least fun sessions I've ever played. I think if we had played perfectly, we could have been average.

3/20/08 - I held probably the best cards I've ever held playing online. Over 25 boards, I held an average of 13.4 HCP, as well as holding 9 singletons, 3 voids, 4 6-card suits, a 7 and an 8-card suit. During the course of these hands, Noble and I scored over 350 points per hand, and almost +3 IMPs against the field per hand (which is not suprising since you win like 3 for bidding your cold games).

8/3/08 - I held the best string of hands I've ever held. First I picked up:

AKxxxx

KQJT9x
followed by:

AQxxx

AKQxxx

Ax
and finally, to top it all off:

AKQ

AKQxx

Axxxx
