D20 covers Oregon, Hawaii, Guam, far northern California NOT including SF, some small part of southern washington, and Boise/Nampa Idaho. No part of Nevada is in D20 now that Reno changed districts.

It would appear the ACBL website needs to be updated then. It says D20 covers "Washington, Oregon, Northern California, Nevada & Hawaii" and includes the following Units:

394 Boise
398 Nampa-Caldwell
452 Vancouver
457 Chico/Paradise
458 Eureka
460 Sutter Buttes
461 Nevada County
464 Redding
469 The Big Island
470 Honolulu
471 Wailuku, Maui
476 Bend
477 Corvallis
479 Eugene
481 Grants Pass
482 Klamath Falls
484 Jackson County
485 Ontario
487 Portland
490 Salem
491 Seaside
492 Mid-Columbia
493 Tillamook
569 Ukiah
572 Central Coast

Guam is apparently part of Unit 470. None of these Units, as far as I can tell, is in Nevada. Idaho, Washington, Oregon, California, and Hawaii are all represented. The map on the D20 website appears to be accurate, and shows the same 25 Units as are listed here and on the ACBL website. The D20 website describes their area as "SW Washington, SW Idaho, Oregon, N. California, & Hawaii".

Seems like somebody should tell the ACBL webmaster of this discrepancy.

From the list of units it appears to be consistent with what Gibson stated. Nevada County is in California, so I can't find the discrepancy you do.

The discrepancy isn't in the list of units, which as you say doesn't include any in Nevada, and which matches the list on the D20 website. The discrepancy is in the general description of the geographical coverage of D20 (on the ACBL site) which still lists Nevada as part of the district.

Their posted map is totally wrong too.

Another form of CRASH that noone has mentioned is over their 1 of a suit opening bid - cue = same colour; 2NT = same rank; 3♣ = same shape. Naturally this is different from the 1♣ and 1NT cases in that both suits are known.

Where I play/direct, this is known as CRO (Colour/Rank/Other) and leads to the same forgets as Ghestem.

Unfortunately some pairs (or at least some players) play it as ambiguous over minor suit openers: (1♣)-3♣ as 5-5 C+H or D+S. This leads to more problems if only one half of the partnership plays it this way and is not always permitted.
