What do you think the odds are of getting an unfavourable flop when you hold a pair of Tens?

These and hundreds more questions are answered in Hilger’s book, but he also gives you the tools you need to work out the rest of them for yourself.

The beauty of the book is that it doesn’t assume you’re a maths genius, meaning the secret codes behind the game of poker should be open to around 93.45 percent of the population.

Oh and that unfavourable flop with Tens? 63%.
