The calendar may not have clicked round to November yet but Willie Mullins already has his string in tip-top form and he took the feature Polar Square Chase at Naas with Twinlight.

Very much an unheralded member of Mullins' star-studded squad until now, Twinlight brushed aside Grade One winners Oscars Well and Realt Mor in impressive fashion.

What looked a competitive race on paper was turned into something of a procession by the six-year-old, who tracked Realt Mor for much of the contest.

There were four in line at the second-last as the favourite Oscars Well and Dylan Ross joined issue but the latter took a crashing fall, with his jockey Robbie Power stood down for the rest of the afternoon.

Walsh gave his mount an inch of rein between the final two fences and the race was over as the 11-4 second-favourite pulled seven lengths clear of Oscars Well.

Mullins said: "That was a big improvement. He came in very strong this season. I was very happy with the way he was after coming in from grass.

"He didn't get a break last year as he was on the go through the summer as we were aiming at the Galway Hurdle. The fact that he got a break this summer, you can see the improvement in him.

"It looks like a fair improvement in form for him to take on horses like that and beat them the way he did. I'd imagine we'll keep him at two miles. I had thought with the strength of him we might go two and a quarter or two and a half.

"He doesn't have to make the running and Ruby was able to sit in behind today. That gives us more options if we decide to go over a longer trip."

Rule The World made a pleasing return from injury when winning the Hospitality At Naas Racecourse Hurdle.

Second at the Cheltenham Festival in March to new Champion Hurdle favourite The New One, he looked the class act on paper beforehand and travelled through the race as such.

However, at the second-last flight Oliver Brady's King Shabra got first run and shot four lengths clear meaning Davy Russell had to work quite hard on Mouse Morris' charge.

The class of the 6-4 favourite shone through in the end, however, and he pulled two and a half lengths clear.

Rule The World fractured a pelvis when running at the Punchestown Festival but made a quick recovery.

Morris said: "We thought he was a goner (due to injury). I've no plans, we'll see how he is in the morning. He'll stay hurdling this season.

"It's just great to have him back. He looks a chaser in the making. Two and a half miles would be his trip. He wouldn't mind going further."

Paul Nolan has always thought the world of Defy Logic and while he maybe did not quite reach the heights expected over timber, his trainer always felt his future was over fences and he made an impressive start to his new career in the Weatherbys Ireland GSB Beginners Chase.

Making all the running under Mark Walsh, Defy Logic (2-5 favourite) jumped well in the main and despite being a headstrong character over hurdles, appeared to settle much better, winning by 19 lengths.

The winner was given a 16-1 quote for the Arkle by Paddy Power, and Nolan's brother and assistant, James, said: " You're always nervous when it's your best horse and I'm glad that's out of the way. He really relaxed today.

"Mark was delighted with the way he relaxed. He said he took a big old blow about seven furlongs out and there is a lot of improvement to come.

"You can't help but dream with him and that's why you get up in the mornings.

"The plan was, that if everything went according to plan today, that he would go for the Craddockstown at Punchestown and we'll talk to Frank (Berry) now."

Aidan O'Brien maintained his 100 per cent record since his return to training National Hunt horses when Noah Webster made a winning debut over obstacles in the Follow Us On Facebook Maiden Hurdle.

After two victories from the smart-looking prospect Carriganog, Noah Webster, without a win on the level after nine races, looked a natural with eight flights of hurdles in his way.

"He did it very well. He was very impressive in a schooling hurdle in Tipperary the other day. He's going to be a lot better hurdler than a Flat horse. He jumped very well and jumped very quickly," said Power of the 14-1 winner.

Courtncatcher (7-1) was a game winner of the Brown Lad Handicap Hurdle for trainer Patrick Duffy and Andrew McNamara, just holding off Jennies Jewel.

"He surprises me everyday and is really full of himself," said Duffy.

"Where we go now I don't know. He has a lot done this year and I can't expect any more.

"I get a real kick out of breeding them, it's a double bonus, and I'm so thrilled."

Racing Pulse (7-2) was an easy winner of the closing bumper for Mick Winters and Mikey Fogerty.
