It's very easy. I played with tankers for some time before I get tired of them and started manipulating the draws. Win 5 matches and start tanking, if at the 10th round you are going down eight, win 1 more. Very easy for tankers. Never under estimate them.

I once had a tanker who wanted to win a treble (I guess) that particular season, at the 7th round he was beaten and started tanking, he finished 3rd from bottom. I'm speaking from experience here.
