David Liu's bidding problem: --- JT76532 K7542 7
Your table estimation is close https://web3.acbl.org/club-table-count/?year=2019&type=R&state=CA I have data to support my claim that our club was among top-ten in CA. My 70% games are rather unexpected. My first was with Alyce Jackson. The 79% with Jo was our third ...

70% games depend on some fluctuations, which happen a lot more in smaller sessions or fewer boards, such as the 299er. The big board requires at least five tables and 20 boards for that reason. On BBO we play 12 boards per game, thus 70% games are rather common.

I am quite sure it was proper misinformation.

You have rounded up the top five under-rated players in one sentence.

I see. Strong enough to bid 3H unilaterally.
Bridge Bulletin Staff Opening
Down six, 2800 or 3400?

Just curious -- was your vote influenced by your exeperience as the TD of that game?

Weird director ruling effects
Given the distance in the bidding box between clubs and spades, a mechanical error is as likely as having a club mixed with the spades, not in a missorted hand but in a bidding box. Strange things happen during a STaC week, but not that extreme.
Delayed Double Ambiguity
Yes, removing 2Sx to 2NT is better. It requires precise defence to beat 2S, probably only one trick.
