I, Timon, am better than Zazoo or CyphR. My last match against CyphR wae about ten against nine for me. Just kidding, CyphR just had not his day. I won with luck (you know he gives me 40-50 blocks and than a chain starts from below, giving him 70 or more). Anyway, It's hard to win against CyphR: nobody is better than him.
Here are the tips you are all wating for (most of them are from CyphR):

Never, ever forget to look what your next blocks are. This is very important, as you have to work very fast in order to survive. It is also important for placing the blocks for your setups.

Always try to chain, because you can kill your enemy VERY fast if you're smart (that means: a good chainer) and fast too.

Try to chain this way: the first 4 chains eatin' only 1 or 2 blocks and the 5th (or 6th) chain eatin' 6 blocks or more. This will drop 40-50 blocks at your opponent.

If you're almost dead, never try to chain (unless your name is CyphR); this will only cause trouble, 'cause you'll have to wait centuries for the right blocks.

Try to keep one column free, so you can put the BB-coins in the empty spot, so nothing dissappears. You can now wait untroubled for the block which can start your chain
