One of the best Monopoly players in the world is Brian Valentine, 30, an 8th-grade teacher from Washington D.C. Valentine represented the U.S. at the World Monopoly Championships in Macau, placing third. Here, he reveals some real-life tips he's gleaned from playing Monopoly.

It is all about location, location, location
Not all properties are created equal, as every buyer needs to know. In Monopoly, some get landed on much more than others - Illinois Avenue and B&O Railroad most of all, according to the game's maker, Hasbro.

But some that are popular with regular players are overvalued, according to Valentine. In particular, he shies away from the yellows (Marvin Gardens, Ventnor Ave and Atlantic Ave.), greens (Pennsylvania, North Carolina and Pacific Aves.) and dark blues (Park Place and Boardwalk). The bottom line: Know your game, in whatever market you are playing.

Relationships matter
Even though there is now a mobile app, Monopoly is traditionally a face-to-face game. That means that how you interact with people is going to affect the outcome. "You can have lots of money and properties, but a lot of the game comes down to human interaction and your ability to make deals with people," says Mary Pilon, author of the book "The Monopolists" about the origins and history of the game.

Do not stretch yourself too thin
Of course you want to collect multiple properties. But if you overspend and do not keep enough of a cash cushion in reserve, then you could go bust by landing on someone else's property.
"While I was writing the book I was also buying an apartment, so the Monopoly themes got really meta," says Pilon. "I never buy more house than I can afford, in the game or in real life. It makes me nervous just thinking about it."

Read your opponents
Just as in poker, the game is often not about the cards you are holding, but about the person holding those cards. Brian Valentine, for instance, made a concerted effort to get to know the people he was playing against at the World Championships, to gain insight and generate goodwill.

A corollary of that: "Don't underestimate people by how they look," says Pilon. "I have a grandmother in her late 80s - tiny, churchgoing, harmless - who is an absolute killer at the Monopoly table. She turns into somebody else."

Never discount luck
As any successful person will tell you, luck plays a role in getting to the top. Same thing with Monopoly. "At the end of the day, it is still a game of dice," says Valentine. "No matter how strategic you are, you still don't really know how the game is going to turn out."
