I don't think I'd bet on Haye if I were you. The odds will not be that good for the chance that Haye has got. The odds probaby will be no worse for Adamek vs Vitali than Haye vs Wladimir, Wladimir is in his prime, Vitali is pushing 40 and ready to retire...
Yes, so if you bet 400 and Haye wins, you make 700 profit and get your original 400 back. So you bet 400 and receive 1100.
