The Timeform verdict on every horse available at three figures in the Aintree betting

Joaaci - current odds [100.0] - As much temperament as ability nowadays and hard to know what to expect. Third at Cheltenham on most recent chase outing encouraging, but plenty with stronger claims.

Baily Breeze - [100.0] - Has run poorly last two starts and looks moderately handicapped. Also, seems best when able to dominate from the front, tactics which will be hard to pull off in this field.

Naunton Brook - [110.0] - Thorough stayer who is best when able to dominate. Sulked when taken on for lead at Uttoxeter last time and that trait is a concern, but best efforts, such as fourth in Welsh National, give him a squeak.

Madison Du Berlais - [130.0] - Likeable type who's largely been in good heart this season. Handicapper has kept apace with his progression though and will need to improve again tackling these fences for the first time.

Cornish Sett - [170.0] - Ran well off a break when second at Cheltenham in November and hope is that he'll bounce back to his best given a three-month absence prior to this. Whether his best would be good enough is a moot point and he looks a dubious stayer to boot.

Cornish Rebel - [170.0] - Has never been the most resolute and form is on a downward spiral, no more than fair efforts in hunter chase company this winter. Rank outsider status certainly justified.

Knowhere - [190.0] - Career-best effort when winning Grade 2 at Cheltenham in January, but let down by jumping when remote sixth in Gold Cup. Unseated at eighth in National last year.

Ardaghey - [200.0] - Likely to be a hairy ride for his jockey given his errant jumping. Form of his win at Cheltenham in October would give him small claims, but he's disappointed five times since.

Iron Man - [200.0] - Has failed to complete both starts over National fences and seems to have gone off the boil of late after a busy campaign, pulled up last two outings. Easily ruled out.

Backbeat - [210.0] - Fluent jumper who belied his odds to win a useful race at Sandown on his reappearance. Forgiven subsequent hurdles flop on account of being turned out quickly. Test of stamina may well suit, but caveat is that best form has been on right-handed tracks.

Tumbling Dice - [220.0] - Not the force he was and seemed to down tools when headed last time. He'll do well to boss this field for very long and entitled to be a three-figure price.

Hi Cloy - [230.0] - Smart Smart chaser at his best, but barely sees out three miles on conventional tracks, ran poorly last time and seems to need plenty of cut in the ground nowadays.

No Full - [280.0] - Third in valuable handicap at Leopardstown over Christmas reads pretty well but little in his profile to suggest this marathon trip is within his compass and he'll need dramatic improvement from this mark anyway.

Opera Mundi - [300.0] - Best on soft/heavy going and weather key to his chance. Still fairly weighted on evidence of penultimate win on soft at Haydock, but ran abysmally on good at Doncaster.

Ollie Magern - [360.0] - Bold-jumping front-runner who increasingly runs more bad races than good ones. Looked to have a hard race when seventh at Cheltenham last time too.

Milan Deux Mille - [430.0] - Took to the National fences pretty well when fifth in last year's Topham Chase, but gone with little zest in three outings this season and big question mark regarding his stamina.

Bob Hall - [600.0] - Progressive handicapper last season but found life tougher off higher marks this time around and last two runs have been bitterly disappointing. Has stamina to prove too.

Nadover - [600.0] - Best efforts on soft or heavy and, though he managed to win a weak handicap at Chepstow over Christmas, he has disappointed recently. Some doubts about his stamina, more doubts about his attitude.

Contraband - [1000.0] - Looks shadow of the horse who won the Arkle at Cheltenham just three seasons ago. Huge stamina doubts and bigger shock than Foinavon if he comes out on top.
