Henry de Bromhead will keep an eye on the weather at Down Royal before committing Sizing Europe to a run in Saturday's JNwine.com Champion Chase.
The trainer's 2011 Queen Mother Champion Chase hero has finished second in the three-mile feature for the last two years.
Behind Kauto Star in 2010, his defeat by Quito De La Roque 12 months ago was put down to the testing ground.
De Bromhead is reluctant to run Sizing Europe in such conditions again.
He said: "We've said we wouldn't run him unless the ground was pretty good. I've been talking to Mike Todd, the manager there (Down Royal), and he says it's good to soft.
"Unfortunately there's rain forecast on Wednesday so he wants to wait until then before he says any more.
"You'd have to feel the ground played a part in his defeat last year. It was soft to heavy.
"I don't want him to go through something like that again - we'd love to see him over three miles on good ground."
The Co Waterford trainer continued: "In November we might look at the Fortria Chase or the Clonmel Oil Chase and for his Christmas run the three options we are looking at are obviously the King George (at Kempton), the two-mile chase in Leopardstown and the Lexus there."
