Howdy.

First, a 75:1 moneyburning bet (Paris/Pattaya):

Zakopalova 2.75
HcHale 2.75
Tanasugarn 2.5
Mirza 2
Martic +5.5 2

Something will surely go wrong here, but I still like it, for a buck or two. Round robin format with several 2 or 3 out of 5's to win also doesn't seem like a bad option.

Also, something more reasonable:

Zvonareva 1.4 (F, Pattaya)
France 1.25 (M, Davis Cup)
Argentina 1.35 (M, Davis Cup)

Odds: 2.4:1

This one should hit. Might make sense to separately pick France and Zvonareva for substantially more money, as I do not see how these two could lose.

Another thing: might be a good idea to pick Croatia over Japan (Davis Cup, 2:1), and then bet Nishikori to win both of his singles matches, to rack up a guaranteed profit. Because if he doesn't win both of his matches, there's no way the favourite Japan is going to advance here...
