WSOP 2018: Untangling the cake riddle and finding the formula to Liv Boeree's heart
Back in May--the eighth, to be precise--Liv Boeree tweeted a picture of a birthday cake. On a Twitter stream that is usually a depository of high-level tech and astrophysics conversation (and occasional yoga or alpaca pics), it may have seemed a little out of place. But this was no ordinary cake.
In fact, the cake in question--a special order from the Los Angeles-based "Cake And Art"--fit right in. It was a two-tier circular effort decorated in numbers, symbols and poker hands, with a big scalene triangle sticking out of its top.

To the untrained eye it was baffling. And even to some people who know what Boeree is like, it didn't make a whole lot of sense. But this was the precise point. Boeree had commissioned the cake to celebrate the 30th birthday of her boyfriend and fellow Team Pro Igor Kurganov, and it was a devilishly clever creation, concealing formulas and riddles of special meaning to PokerStars' most beloved pair of calculus junkies.
"He loves maths, everything to do with maths he loves," Boeree said today, when asked to untangle the riddle of the cake.
So here we go. Here's what it all means. We'll start at the very top.
"This obviously is a triangle and the angles of a triangle add up to 180 degrees," Boeree said. "So 70 and 80 means that's 30." She pointed to the corner labelled "Igor".
"Similarly where it says 'Happy...really complicated formula...Birthday Igor' that also adds up to 30. It took me forever to find something that looked as complicated as possible but that equalled 30. It was surprisingly hard to do. I sat for ages, trying to backwards engineer."
And it wasn't quite right, Boeree confessed. "Actually, I missed out a minus sign, that's actually minus 30," she said. "Someone picked that up. I was impressed."

Wrapped around the rest of the top tier is a push-fold chart for no limit hold'em, which means a player need only be sure to be munching birthday cake at the tables to know what's a correct +EV shove with a short stack in a tournament. Handy.
On to the lower tier, and things start to get personal. The number curved around the surface reads 0.142857142857 and it is, according to Boeree, nothing less than the key to her heart.
"It's Igor's favourite number and it's one divided by seven," she said. "That was the number...he explained it to me a few years ago, before we got together, and his explanation of it is so beautiful, it's such a beautiful number the way it repeats on itself. It was that that made me fall in love with him."
She added: "His explanation was so beautiful, I thought: 'This is the guy for me.' He manages to make maths sound so beautiful."
So there it is: You can keep your fast cars, designer threads and bouquets of red roses. The only way to impress Boeree is with numbers.
"We're just both nerds," Boeree said.
