1. Ballybeg Boss (IRE): This Irish point winner has shown consistent form, finishing second in all three starts under Rules. With a strong performance at Carlisle, even with a 25l gap behind the winner, he has the best form in this field. Ballybeg Boss seems to be a reliable contender in this race and is likely to maintain his good form, making him a solid favourite for the top spot.
2. Jersay Du Trottet (FR): With a promising start in his career, Jersay Du Trottet finished third at Pau in his hurdles debut. He was always close up and displayed a determined attitude, which bodes well for his British debut. Considering his potential for improvement and adaptability to the UK racing scene, Jersay Du Trottet is a strong each-way contender and could challenge for the win.
3. Kapamazov: Finishing second in an Irish maiden point and fourth in a novice hurdle at Hereford, Kapamazov has demonstrated decent form. Although his performance at Hereford is not the best in the field, it still places him among the serious contenders for this race. The drop in trip may suit him, and with potential for improvement, Kapamazov could be in the mix for a top-three finish.

In summary, Ballybeg Boss stands out as the favourite, while Jersay Du Trottet and Kapamazov also have potential to finish in the top 3. Keep an eye on market movements and any additional information that might affect the horses’ chances, but these three appear to be the strongest contenders in this race.
