Only advice is make good hands and bet them. Value hands like top pair top kicker very highly.

I play in a tournament like this sometimes and it can be frustrating because you feel like you do need cards to beat these players, but they don't need cards to beat you. It's like by being so bad and calling with any 2 cards they are impossible to read and you have to take a view whether your hand is good.

Know one thing - if you hit cards you will win!
