Sorry the pic is big, but you get the idea. Betting 2 treble bets means you can remove all risk on Williams and Martinez and hope that Murray and Stieglitz win, which they most probably will. £500 spend for a possible £125 - £220 almost guaranteed profit?
Obviously it can be reijgged to however much you want to spend but removing most risk comes at a high price so £500 is reasonable
Can you be sure there will be no draw? Williams martinez was a draw in my opinion the last time, this time will be a war and very close fight, I think about putting 10 euro on a draw myself. Allthough it is unlikely and you probably will have nothing to worry about.
I think both fighters have too much at stake, the winner will inevitably fight Pac and Martinez will be looking for redemption from the last time they met. I thinkit may swing in Martinez' favour, I might weight it more evenly or weight it slightly towards Martinez...
Rejigged in favour of williams, otherwise you may as well do a double without the Williams/Martinez fight even included
