A fold up umbrella is usually handy. Can act as a sunshade or to keep dry whilst scanning the betting boards. Just make sure your wife/girlfriend has a bag to put it in if it's not needed. I'm reduced to this type of advice as my horse tipping service is crap and I'm looking to the experts on here to come up with some gems. Haven't actually studied the form yet but if I see what I think is a banker I'll post it here for you to lay off.
I think Goldikova currently at 13/8 is good value. Rio De La Plata @ 25/1 EW if all 8 run is good value. Best to do a place only bet for Rio DLP on betfair this gurantees 3 places incase of any non runners and better price than the EW place would pay because your betting place only. Rio has a multiple Group 1s and needed that run. Just look back for the last few years and has conistently ran badly after a long lay off.
