I am careful what meetings I look at on Saturday’s. I don’t like the big meetings so have not studied Newbury, Newcastle or Doncaster other than one race at Donny that Sunchu marked up. I therefore have no view on your selections other than I noticed Robinshill would come close to being a Pollination qualifier if I was looking at Newbury. I also hate betting in Chases and made an exception with Beauboreen but that run sums up what I find with betting over fences. Best left alone for me.
Good luck today.
