Get treasure cards because they are extremely important.
Remember that the game has a bluffing element. i.e. When you have a high bonus treasure card early, you can act like you are cursed.
Even when you loose battles, nobody wants to steal your treasure card.
Use the movement cost to your advantage.
Check if you have enough food or doubloons.
Move past what you want and if you don't have enough food/gold, move backwards to land on the space you really wanted.
You don't need to win the race to win the game.
Save your double move forward card untill the end of the game because it can be a game changer.
Don't underestimate your role as a captain.
Get enough gunpowder ready if you aim for a battle.
