Trainer John Size's All Bountiful opened up a new avenue of possible riches for connections when making a nice transition to racing at Happy Valley following a pleasing fourth in the Class Four Pui O Handicap (1,800m) on Wednesday night.

All Bountiful showed ability at times over various distances at Sha Tin with market support, but he is certainly starting to show signs in recent runs and will be opening his account for Lucky Lord Syndicate, who have enjoyed a good time with the likes of six-times winner More Bountiful and five-times winner Bountiful.

The four-year-old was plunged late in the betting - $100 to $54 (favourite) - despite drawing an always difficult outside gate 11 in his debut at the city course for Douglas Whyte.

All Bountiful was in no hurry and slipped underneath rivals to settle third from the rear, was back to last at the 600m, pushed into the clear widest out rounding the final bend and was finishing up strongly to go under by 1½ lengths to the in-form Hei Hei Posh. He posted the fastest final 400m in a smart 23.38.

The four-year-old is a son of the Australian Guineas (G1) winner Al Maher and Grosvenor mare, La Blanca, a seven-time winner in New Zealand from 1,200m to 2,100m in 33 appearances.
