The complicated gamesmanship that preceded approval of the mammoth Tysons II project by the Fairfax Board of Supervisors this week has been compared to a cross between Monopoly and Trivial Pursuit, but the stakes were no child's game.

The developer, H-L Land Improvement Venture, officially has "passed go" and is expected to collect future income far in excess of the meager $200 Monopoly players collect. And shopping center magnate Theodore Lerner, the joint venture partner in the Tysons II project with Homart Development Co., gained something multicolored Monopoly money won't buy -- a major interest in a very big shopping mall.

Along the way, developers coughed up more than $14 million in promised road improvements to add to the "community chest" of roads proffered by developers countywide.

Citizens groups, particularly the McLean Citizens Association, staked their claim as experts in pursuit of concessions they deem far from trivial. They fought to get a bridge across Dolley Madison Boulevard connecting Tysons II and the existing Tysons Corner shopping center. While the bridge they got is not exactly where they wanted it, the structure will be so valuable that one resident said, "the MCA got a Boardwalk."

Weeks ago, project attorney John T. (Til) Hazel said the project was "being held hostage to transportation problems." His predicament was similar to that of a player who is told to go directly to jail without passing go. And Hazel engaged in a battle of wits over past rezonings on the Tysons II site with Lilla Richards, chairman of the MCA's Transportation Committee, who is considered a master of zoning trivia.

Here is a look at other major players in the elaborate Tysons II board game:

*Wayne Angle, stoic and always polite, is the H-L Land Improvement executive who masterminded the development project after attorney Hazel convinced Homart Development Co. and eventually Sears, Roebuck & Co. -- all part of the Tysons II corporate family tree -- not to build a series of office buildings on the 107-acre site.

*Theodore Lerner, the joint venture partner, remained largely in the background. Fairfax Supervisor Nancy Falck started studying the issue when she joined the board of supervisors in 1980, and proponents say her work resulted in many traffic improvements she extracted from the contractors.

*Carlos Montenegro, a law student, is the Fairfax planning staff member assigned to the Tysons II case. He spent more than 400 hours on the project, working with citizens, politicians and developers. Some observers say he probably learned more from working with Hazel than he did in classes.

*James Lewis, a lawyer turned developer, is the tycoon behind the giant Tycon Towers complex being built next to the Tysons Marriott. Lewis pulled Tysons business executives and developers together to back Tysons II.

* Audrey Moore, a Fairfax supervisor, publicly announced she would oppose the project in the final days before the vote. She said she would be "chased out of her district" if she voted for the project. Her critics say she wanted publicity, and that she knew the project would pass.

*Gloria Adams, president of the McLean Citizens Association, was described by both sides as "soft-spoken, blunt and to the point." She managed to represent the association without alienating anybody.

*Charles (Chuck) Ewing, head honcho at Westpark Office Park, will be the project's most immediate neighbor. He reportedly was miffed at Tysons II's plans to reroute Westpark Drive, but eventually his development group agreed to fund widening of a stretch of International Drive.

*Richard Keller and Shiva Pant handled many of the transportation aspects of the issue
