Trained by Nicky Henderson and ridden by Jerry McGrath, the nine-year-old was a 10-1 shot for the first handicap of the Festival in a fiercely-competitive field of 24 runners.
For much of the way it looked like Up For Review might give Willie Mullins his third winner of the afternoon as he travelled powerfully on the heels of the leaders running down the hill.
However, he made a mistake three fences from the finish and his effort soon petered out.
Beware The Bear – a winner at Cheltenham in January – was in the lead at the top of the home straight and while Sue Smith’s Vintage Clouds finished strongly, Henderson’s inmate had just enough in reserve to hold him at bay.
Nick Alexander’s top-weight and
Grand National contender Lake View Lad ran a fine race to finish third ahead of Lucinda Russell’s Big River – another Scottish challenger – in fourth.
