This particular setter is very bad. A lot of the time I don't get his meaning at all. He's a fairly new setter for this particular xword - my heart sinks when I see his name at the top.
9d Drink a large amount , right, in tin? No (7) ?I?S?ER is it pilsner
10d Reserve doubt about Thailand's sports arena (8, two words) ?C?T?AC? ...Track perhaps??
Thanks for your help
