Jessolle looks to have been found a good opportunity in the novice chase at 1.30, Micky Richards' mari in receipt of 12lb from the recent course winner Lagansidj. Three of the six runners in the two- mile handicap chase at 2.00 have winning form at the track, but the most interesting one is arguably the top- weight Mulkev Prince.  Totes/MRs Chjl Res Ayr Res Folk Res
