This will truly be a battle of the minds.
You can just picture the poker faces. The challenge for these guys will be to retire before the other one does, but one can't retire prematurely - that would look suspicious. It must be subtle, appropriate, dramatic. There needs to be a perfect game plan worked out.
My money is on Davydenko to retire - he'll pull it off brilliantly, leaving Volandri's in the dust. Volandri will be a defeated man, having to tolerate another match with a much lighter wallet. Davydenko will be bumming in St. Pete's with the ladies, his pockets full of mafia cash.
