Nadezda Petrova provided another winning best bet for this column on Thursday by taking the opening set against Petra Kvitova.
The Russian should have won the match in straight sets at 3-0 up in the second set as well, but failed to see it out and went on to lose the decider.
It's quarter-finals day in Doha today and it's not that easy to select a bet, as all of the favourites look pretty solid and I'm struggling to make a case for any of the underdogs.
The best play I think is to take Vika Azarenka to inflict a fairly heavy defeat upon Sara Errani and take the unders at 17.5 games.
Errani hasn't been at her best so far this season, with five losses at odds-on already in 2013 and defeat on clay in Davis Cup to Varvara Lepchenko last week.
She just about scraped past Daniela Hantuchova yesterday and she's not in the sort of form to test Azarenka, who inflicted a double bagel thrashing upon Christina McHale on Thursday.
Aza's Valentine's Day massacre shows, if it needed highlighting, that the world number one is in the mood early on this season and she has made short work of Errani in their most recent meetings.
In the three matches played between the pair since 2009, Azarenka has won in 15, 15 and 16 games. Although Errani's form has improved since their most recent match in 2011, her game is set up for Azarenka to hit right through.
The Italian's weak serve plays into the hands of Azarenka's tactic of hammering the return and I'd be surprised if Errani is able to hold serve too often today.
Best Bet: Back under 17.5 games in Azarenka vs Errani at 1.75
