The Greek god Apollo was in charge of many things: medicine and healing, light, truth and archery. He was also a bringer of death-dealing plague. Well, nobody’s perfect. Inscribed into the forecourt of his temple in the ancient city of Delphi were the words ‘gnothi seauton’, which translates into our humble language as ‘know thyself’.

Remember those words each time you peer down at your hole cards, because if there’s one thing which could potentially rain bankroll-crushing pestilence upon you it’s not knowing your own game. Are you an aggressive player? If you know that you are then others probably will, too, so you’ll need to be watchful of when others are trapping.
