I've done that in a strong club system, but it is midchart in the ACBL which is a PITA as you can't use it in many events.

Douglas Drury died in 1967. In his era players were opening 13 counts. The game is becoming more and more aggressive. Today the side who opens the bidding gets in the first blow, taking away bidding space from the opponents at the same time. In todays game, Drury has become obsolete.

Barry Crane was murdered in 1985. In his system all 11 counts with an ace or king were opened. Instead of Drury becoming obsolete in his system, it was played in all four seats until the ACBL outlawed that.

To put it more simply than Helene did, what is the point of using Drury when you have already opened?

I wouldn't open this but would love to have a Drury raise available after partner opens 1

Wow! I had to Google this, Murder of Barry Crane.

Oh, I see that I got it wrong. Druryx4 was once OK and then removed from the general chart. Does anyone know why?

BBO members have revealed futuristic treatments integral to Barry Crane's system (e.g. Light opening bids and Drury in all seats). It's surprising that such innovations didn't cause more of a stir at the time. Were they properly disclosed?

Because allowing in 1st 2nd seat was an invitation to psych with Drury being used as a psychic controller.

ACBL doesn't like psychic controller bids

How is it any more a psych control opposite a first-seat opener than it is opposite a third-seat opener?

Was it a fairly recent change, or does Inquiry play non-GCC events?

This is why it is relatively recently that the EBU permitted Drury. But they didn't restrict which seats you could play it in. It seems on the surface that 3rd and 4th seats would be the worst ones from this perspective. But whatever.

Yes, most events use the General Convention Chart. Some upper level events use higher level charts, primarily unrestricted level games at NABCs, and a few others.

Honestly I feel like most events I play in these days are mid-chart. This includes GNT, NAP, bracket one or two KOs, strati-flighted swiss teams, various national pairs and team events, etc. In general if you stick to the highest flight things are mid-chart, although this won't hold for smallish events with a lot of weaker players in the field (i.e. stratified open pairs).

Seems like Drury is useful after all as it can be used for a Controlled Psyche.

Light openings (within reason) are not psychs. So Drury is not a psychic control.

I do understand why some might look at Drury in that manner. But you have to be using a bid intended to deal with a psychic bid for that bid to be a psychic control.

I do not think that intention has anything to do with it. If it looks like a duck etc. And I do think that a "light" opening such as 1 on xxx, x, Qxx, K109xxx is in fact a psych.

The psychic control thing is not as clear-cut as people make it out to be. I mean, Stayman is a psychic control because of a lot of hands which are worth game or more bid 2 over 1NT, giving opener a chance to pass if he psyched the opening? This seems extreme, but it's the same case people make with Drury.

To really be a psychic control, it's not enough that partner didn't immediately blast the maximum contract which should make opposite a non-psych. People don't really bid this way any more (if they ever did) and it risks missing a slam in many cases. You need a call that seems illogical opposite what partner supposedly showed (for example letting partner out in a partial when holding an obvious game force).
