Born in Vietnam, Chau Giang escaped the war-torn country in a boat in the late seventies, eventually arriving in Florida were he found employment. Giang later moved to Colorado, where he learned to play poker while working as a chef. Quickly catching on to the strategic aspects of the game, Chau Giang was soon living in Las Vegas, where he won over $100K during the course of his first year as a full time poker player.

Primarily a cash game player in his early career, Chau Giang always made an appearance at the World Series of Poker. In 1993, Chau won his first WSOP bracelet, and $82.8K in $1,500 Limit Ace to Five Draw. He also cashed in three other WSOP events that year, including a 2nd place win in Pot Limit Hold'em. Two years later, Chau Giang cashed in five more WSOP events, making it to two final tables.

Snatching up his second WSOP bracelet in 1998, Chau Giang took down the $2000+$70 Limit Omaha Hi/Lo event for just over $150K. Two more final tables that year brought in an additional $16K. Between 2001 and 2002, Giang made four more final tables at the WSOP for over $150K.

The third WSOP bracelet Chau Giang claimed came in the 2004 $2000 Pot Limit Omaha event of the WSOP, along with just under $188K. He also earned over $60K in three other WSOP finishes that year, in a variety of poker forms.

Chau Giang has continued to enter the World Series of Poker every year, frequently cashing and often reaching a final table. Giang has also dabbled in a small selection of other tournaments, including the Asian Poker Tour and the World Team Poker Invitational, placing fifth in each in 2010.

In recent years Chau Giang has come to focus more on tournament poker. He also plays online poker at Full Tilt under the handle "La Key U". A formidable opponent in any poker form, Chau Giang is easily numbered among the greatest poker players of all time.
