Playing heads-up is the closest you’ll ever get to feeling like you’re playing Russian roulette with Christopher Walken in The Deer Hunter. There might not be a gun to your head, but going toe to toe at the poker table is a high pressure situation.

And if you can’t conquer this aspect of the game then there’s no chance that you’ll be able to pull off your dream win, like American Chris Moneymaker.

Moneymaker busted opposition out through a number of online satellite tournaments on his way to winning the World Series of Poker Main Event in Las Vegas in 2003, scooping $3.6 million when he knocked out his last opponent on the final table.
