Moya v Benneteau. Will be interesting to see Moya in this one. He's on a very poor run lately losing all 3 of his matches so far in the European clay season. But I can't help but look at what he did here last year, reaching the semis beating Berdych, Blake and Djokovic and taking a set off Federer. Also last year he start the European clay season poorly (not as bad as this year) before being very strong here and at the French. Don't write him off just yet! Benneteau seems in pretty average form, but he did come through qualifying. This could be a decent match up for Moya to get back some form, but just touching 1.55 doesn't appeal too much.
Robredo v Kohlschreiber. This one seems to be about scheduling. Tommy has had a lot of matches lately including a couple of final set breakers and could be due a flat performance. However, wouldn't expect it to come here - the scene of his greatest success winning the title in 2006. He lost first match last year to Almagro (really tough draw!) and should be looking to make amends this year. Kohlschreiber pulled out of Munich with a respitory infection and I've got no idea how he is physically. At home could be a decent price for the German but don't rule out Tommy. Quite fancy 3 sets so laying whoever wins the first set could be profitable.
I took Moya on your advice

after that success i've taken Robredo as hes just gone down a set! I fancied him from the start to be honest so pleased now about my enhanced value!
