.xyz

.xyz is a top-level domain name. It was proposed in ICANN's New generic top-level domain (gTLD) Program, and became available to the general public on June 2, 2014. XYZ.COM and CentralNic are the registries for the domain.

In 2015, XYZ.com proposed that ICANN allow it to ban thousands of potential .xyz domain names from registration by global registrants in order to comply with censorship demanded by the People's Republic of China. XYZ.com hopes to become an officially recognised registry in China, which would allow it to directly offer domains to Chinese customers.

In November 2015, .xyz reached 1.5 million domain name registrations, possibly boosted in part by Google's decision to use abc.xyz for its corporate (Alphabet Inc.) website. However, domain name registry VeriSign and others have claimed that domain name registrar Network Solutions gave away possibly hundreds of thousands of these names by placing them into customer accounts on an opt-out basis.

As of January 2016, .xyz was the 6th most registered domain name on the internet.

XYZ convention

XYZ is a bidding convention in contract bridge.

Using the convention

After opener's one of a suit (X), partner's one of a suit response (Y) and opener's 1-level rebid (Z) (a very common sequence), 2♣ from opener's partner forces 2♦ from opener. Holding a weak hand with diamonds, one can now pass. Other bids are invitational, describing also the nature of the hand. A 2♦ rebid by responder, however, is game forcing with any hand. Responder may also jump to 3 of any suit (except 3♣, which is signoff) to show a game-forcing hand with a good suit or, if the jump is in one of opener's suits, two of the top three honors.

Although it is mandatory in the XY Notrump form of the convention to complete the relay 2♣ to 2♦, when Z was a suit, opener may be unlimited. In such a case it is acceptable, if opener has too good a hand to risk being dropped in 2♦ to bypass the relay and make a (forcing) bid.

It is also customary to retain the convention in the face of certain competitive actions, for example after a double by opener's LHO, or a negative double by partner. After an overcall by RHO, assuming that the bidding has not gone past 1NT, the convention is still on (for example after 1♦ pass 1♥ 1♠ X where X is a Support Double).
