Kim Bailey feels it could be worth trying to take advantage of the current heavy conditions with Harry Topper in the Denman Chase at Newbury this weekend.
Despite once again putting in a few sticky leaps last time out in the Argento Chase at Cheltenham, the Charlie Hall winner stayed on strongly to take third.
While he also has options at Kelso and Haydock next week, Bailey could be tempted by the £50,000 contest this weekend.
"I have made a surprise entry for Harry Topper at Newbury on Saturday in the Denman Chase," he wrote on his blog.
"Harry Topper has his ground and seems to have come out of his recent Cheltenham race in fine form, so I thought it was worthwhile looking at the race as he still has his preferred soft ground.
"We do have other opportunities next week in the Ivan Straker Memorial Chase at Kelso next Thursday and the Grand National Trial at Haydock next Saturday."
Venetia Williams has entered Katenko but his participation is far from certain.
Having been struck down with colic last season after emerging as a lively outsider for the Gold Cup, the soft-ground lover was a close fourth in the Peter Marsh Chase last time out.
"He's in good form and he's ready to run, but it's not been decided about Saturday yet as he has another option a week later," said regular jockey Aidan Coleman.
