I wouldn’t get too hung up about any draw "bias" on the straight course – as has been previously suggested – look for where the pace is.
I have lost count of the number of times I thought I have cracked the draw only to have it totally disproven in the next race.
I recall a meeting last year where there were two big field six furlong sprints. In the first the first six home were all far side. Pretty conclusive you would think. However in the next the first five home were all stands side!!! Then later on in another race all the action was centre course.
Mounty’s bookmaker pal has a very good point and if you ever want a dramatic demonstration of the effect of the grandstand shadow then go early to an Ascot winter meeting after there has been a frost and you can see where half the course thaws easily and the other, shaded, half needs intensive work from the groundstaff.
