Wrong Turn survived a lengthy stewards' inquiry to win the opening race at Leopardstown.
The Tony Martin-trained 5-1 joint-favourite defeated Mackeys Forge by a neck in the Martinstown Opportunity Handicap Chase, but there was scrimmaging after the two horses jumped the last in unison.
Although Wrong Turn and Mackeys Forge got close along the run-in, the local stewards left the places unaltered.
Martin was quick to praise 4lb claiming jockey Shane Shortall for getting Wrong Turn home by such a slender margin.
He said: "Shane is good value for his claim and has a good head on him.
"He (Wrong Turn) is a good leaper for a novice."
Shanahan's Turn (2-1 joint-favourite) turned in a most accomplished display to claim the Ryanair Maiden Hurdle.
Trained by Henry de Bromhead and ridden by Andrew Lynch, the Irish point-to-point recruit readily accounted for Blue Bicycle in what looked quite an informative heat.
Stoney nudged into the front two flights from home after Masterofdeception had initiated a fair pace.
But his position of authority was short-lived as Shanahan's Turn glided into a lead which stretched to four and three-quarters of a length by the winning line.
De Bromhead said: "I was a bit disappointed with him at Down Royal, but he needed further.
"He jumps well and will go chasing next season."
