India Wins Newzealand In Test series as 1-0



  • The Indian cricketers, having emerged triumphant in a Test series in New Zealand for the first time after 41 seasons, were accorded warm welcome upon their return home on April 9.

  • They returned home in batches in different cities after having done a fabulous job in New Zealand. The victorious skipper Mahendra Singh Dhoni, Man-of-the-Series Gautam Gambhir, opener Virender Sehwag, fast bowler Ishant Sharma and leg-spinner Amit Mishra landed in capital New Delhi while the legendary batsman Sachin Tendulkar alongwith spearhead Zaheer Khan, off-spinner Harbhajan Singh, medium-pacer Munaf Patel and young Dhawal Kulkarni disembarked in Mumbai.

  • The batting stalwarts Rahul Dravid and VVS Laxman flew into directly to their respective cities, Bangalore and Hyderabad.

  • The Indian cricket fans had the reasons to feel proud of their team who had overcome all the obstacles to record their first Test series win in New Zealand after Mansur Ali Khan Pataudi's team had downed them on their own soil in 1967-68.



  • The ride has been rough and bumpy for the Indian sides over the years having had to endure the cruelties of the nature besides taking care of their form. What happened in the third and final Test at the Basin Reserve in Wellington was so typical of their fate. It has remained so near yet so far story for them on a number of occasions.

  • Their win in the first Test at the Eden Park, Auckland, was their maiden Test triumph on the New Zealand soil for 33 years or so. They should have won handsomely the third Test as well to take the series 2-0. But the manner in which they were robbed of the win in Wellington suggested they might need decades if not centuries to accomplish it.

  • The Indians have won so few matches, despite having dominated decisively so many times, that they value their every win much more than any other team despite being in possession of the strongest outfit in the business.

  • That could be one reason why the Indians sometimes play cricket that looks unusual if not mind-boggling. They know how difficult it’s for them to complete a win. Therefore they adopt tactics that are different to other teams.

  • Sometimes you have to pardon them for not delivering because of their consistent hard luck. They should have aimed for a whitewash over the New Zealanders but their own performance was terrible in the second Test at the McLean Park, Napier, where they had to play out time save the game.

  • One is not sure how Dhoni has been labeled as a lucky captain. Yes he may be less unluckier than his predecessors but to expect the luck to go with him is something beyond my comprehension. That’s why he may not be able to have the success rate as high as that of Ricky Ponting or Clive Lloyd despite having the capacity of doing better.

  • Ponting and Lloyd didn’t have to fight the nature. They got the value for their performance. Not Dhoni. If he had just normal luck, his side would have won the Wellington Test.






Malaysian GP 2009



  • Jenson managed to win his second race in a row and he even managed to overtake this time. To be fair, I think he ran a good race in difficult circumstances and he deserved this race which was abandoned on lap 32 by monsoon rain.
  • He grabbed pole on Saturday but made a bad start.
  • Nico Rosberg who started in 6th made a brilliant start and jumped into the lead followed by Jarno Trulli and Alonso.
  • Alonso was fat with fuel but Button made a great move to pass him.
  • He overtook Trulli during the pit stop but when his car was light on fuel, he clocked some of the fastest laps of the race.
  • I will give him credit for this race! The rain caught a lot of the teams out and those who tried to be clever with their strategy failed.
  • Usually in Malaysia, when it rains, it rains suddenly and hard.
  • However on Sunday, the rain took a long time to settle into the downpour that ended the race.
  • A lot of the teams, expecting a deluge, changed onto extreme wets. However Glock in his Toyota went on to intermediates.
  • It quickly became apparent that this was a great decision by the team and those that had chosen the extreme wets had to come back to change to intermediates but only a few laps later, had to go back to the extreme wets.
  • Ferrari messed up spectacularly.
  • They pulled Kimi in early and changed him to extreme wets when it did not even look as though it was raining.
  • He burnt his tyres long before the rain came.
  • Having started in 9th, he finished back in 14th.
  • Team mate Massa did not fair much better finishing 9th and out of the points.
  • It is not a bad finish bearing in mind he started in 16th having made a huge mistake in qualifying, thinking his time was safe.
  • There was great racing between Alonso and Mark Webber.
  • They were passing each other as though they were on Moto GPs.
  • They finished the race with Webber in 6th and Alonso 11th.
  • The Toyotas who had made the best tyre decisions finished Glock in 3rd and Trulli in 4th.
  • Rosberg who was posting the fastest laps at the start of the race got caught by the rain and the pit stops and ended back in 8th which is a very disappointing finish, he deserved so much more.
  • Another disastrous weekend for the McLaren team insofar as PR was concerned. Lewis started 13th ahead of Heikki in 14th.
  • Heikki did not make it round the first lap whereas Lewis showed his brilliance in the rain making some fantastic overtaking moves to finish 7th.
  • Kubica in his BMW retired early with flames coming from the car. He had out qualified team mate Heidfeld having started in 8th ahead of Heidfeld in 11th.
  • Heidfeld however finished 2nd. Perhaps we will start to see where Kubica stands psychologically.
  • We know he threw his toys out of the pram last year when he felt the team did not support his title race.
  • He is now running a different car to his team mate having refused to try the KERS system.
  • If Heidfeld continues to put it to good use, Kubica is going to have to change.
  • The rain affected race meant that it was abandoned and half points were rewarded. For the full result, see below.
  • This is an action packed start to the season but as a McLaren fan, it is not quite what I would want particularly with the threat that McLaren are going to face further sanctions from the F1A.
  • This seems ridiculous to me.
  • The team and Lewis were punished by having their Australian points deducted.
  • The sport now needs to move on and focus on the forthcoming races. To drag out an investigation and potentially an appeal just leaves a black cloud hanging over us.
  • Bearing in mind the way Schumacher behaved throughout his career, and the lack of penalty he and his team received, it just seems to highlight once again the F1A witch hunt against McLaren.
  • The only problem is, it is the sport that is the loser.

Indian Hockey win Sultan Azlan Shah Cup




IPOH, Malaysia (AFP) — India clinched their fourth Sultan Azlan Shah Cup when they defeated hosts Malaysia 3-1 in the final here on Sunday, giving them a huge boost ahead of the Asia Cup next month.

The Indians, ranked 10th in the world, were last champions in 1995 but saw off the 15th-ranked Malaysians with three field goals.

It was notable also because it was the first match in the tournament here that skipper Sandeep Singh -- voted player of the tournament -- did not score a goal for India.

But it hardly mattered, as India started off the match with a goal in only the eighth minute through Arjun Halappa.

However, three minutes later Azlan Misron put Malaysia back on level terms with a strike from close range.

Prabhjot Singh and Shivender Singh made the game safe for India with field goals in the 20th and 41st minutes.

"It was a great day for Indian hockey as we are slowly getting back on our feet. Now is the time for us to look ahead at the Asia Cup, which will be held next month," said India coach Harender Singh.

Earlier, New Zealand took third place when they scored two early goals to beat Pakistan 2-1 in the third-fourth place play-off.

Pakistan coach Shahid Ali Khan was disappointed with the result but not the tournament overall.

"It is certainly not the result we wanted," he said.

"But overall this tournament has provided me with a lot of data on the players and we will have to work on the weaknesses before the Asia Cup next month."



Review:Aayan

Star-casts: Surya, Thamannah, Jagan, Prabhu, Akashdeep Saigal and many others.
Production: AVM Productions, Sun Pictures
Direction: K.V. Anand
Music: Harris Jayaraj
Cinematography: M.S. Prabhu
Editing: Antony





Gangster stories, double-crossings, informers – This isn’t something clichéd when it comes to Tamil Cinema. Of course, we could’ve watched many times on the screens, but they weren’t something more precisely presented. K.V. Anand delivered his knack of blending an crucial concept with commercial elements right in his debut directorial ‘Kana Kandein’. Well, on the same tracks, ‘Ayan’ takes off with one such theme.

Deva (Surya) smuggles foreign goods, Gold and diamonds for Doss (Prabhu) who has bought him up right from his childhood… His sidekick Chitti Babu (Jagan) and a deaf driver (Karunaas) accompany him in all conniving acts. Deva and Chitti Babu turn to be close friends and indeed Chitti’s sister (Thamannah) falls in love with him. A good friend, a lovable sweetheart, A Caring Mom (Renuka) and a father-like Doss. What else does a man need than this? But Deva’s main impedimenta is through Kamalesh (Akashdeep Saigal) who keeps informing cops about the collusive tasks carried through Deva and Chitti. Doss doubts about the deaf driver to be the informer. Unfortunately, it’s really appalling when unraveled about the real informer.

Surya has adeptly carried through the performances top-notched. He’s extraordinarily matured compared to his previous flicks. He’s perfect with spellbinding stunts, decent romance and emotional sequences. Thamannah deserves commendable credits for the crème de la crème acting. She had done what many of our actresses failed to do on the screens other than skin shows and dancing horribly. Thank you Thamannah, we made us like your decent show. Prabhu steals the show and in many scenes his characterization goes powerful than Surya. Jagan has been portrayed with a stunning role that’s more than comedy. Certainly, the entire script revolves around him. Renuka deserves good comments while Akashdeep Saigal could’ve been presented with yet more rigid role.

Screenplay and characterization is more brilliant. K.V. Anand proves himself to be off a skilled filmmaker with an interesting narration. Merely, in the second half, the film looks bit flimsy in screenplay and anyhow, it makes up grandly towards the climax scene (Catch Me If You Can – Style). Most of the sequences have been inspired from ‘Lord of Wars’.

Harris’s musical scores works with couple of songs ‘Pala Palakura’ and ‘Vizhi Mudi Yosithal’. But why does he stumble more on background score is worth asking question. Cinematography is good at many parts and mediocre in few portions while Antony comes up with a matured touch unlike his previous films. Dialogues are catchy.

On the whole, ‘Ayan’ reveals about K.V. Anand’s real taste of good cinema. So, it’s a film worth watching and you’re sure to enjoy doing it so.



Bahrain GP 2009


Jenson Button has taken victory in the Bahrain Grand Prix from fourth on the starting grid. The World Championship leader pulled clear of the chasing pack as Sebastian Vettel and pole-sitter Jarno Trulli completed the rostrum. Champion Hamilton finished fourth as Kimi Räikkönen scored Ferrari’s first points of the year.

Jenson Button had strong doubts over his chances in the Bahrain Grand Prix, especially after qualifying fourth on the grid in qualifying. Jarno Trulli and Timo Glock were the men to steal the show on Saturday by taking Toyota’s first ever front row lockout, with Sebastian Vettel’s heavier fuelled Red Bull lining up third. Temperatures soared to 38°C (100°F) at the start of the race, as weather conditions couldn’t have been any different to those in China last weekend.

The Toyotas made a strong getaway although it was Timo Glock who led at Turn 1, with Lewis Hamilton making a lightning start with KERS onboard to charge up to third place before passing pole man Trulli for second. The Italian duly retook the spot at Turn 4, as contact between the first two corners resulted in unscheduled pit stops for Massa, Nakajima and both BMWs.

Button found himself behind Hamilton, as expected, but was able to pass Sebastian Vettel. The Brawn team’s key to success, however, was being able to run for longer than those in front to be able to jump the pack after the first round of pit stops. Timo Glock, who led in the opening stint, was the big loser as he was overhauled and ran as low as eighth, eventually recovering to finish seventh, just behind Kimi Räikkönen who took Ferrari’s first points under the watchful gaze of company President Luca di Montezemelo.

Despite the many changes made to the cars for 2009, reliability was surprising good in the Middle Eastern summer heat as only Kazuki Nakajima retired in the final third of the Grand Prix, pulling into the Williams garage with technical problems. The race featured several exciting overtaking manoeuvres, the most spectacular of which came from Fernando Alonso on former team-mate Jarno Trulli during pit stop windows in the middle of the race, passing the Toyota around the outside of Turn 4.

Button was able to pull out a lead as big as 17 seconds during the race, thanks to the colossal duel for second between Trulli, Vettel and Hamilton. The World Champion slipped eight seconds behind the pair when using the Super Soft tyres for his last stint, although Trulli continued to chase Vettel right to the chequered flag after the Red Bull driver jumped the Toyota.

Button’s third win from four races this year hands him a 12-point lead over team-mate Rubens Barrichello with Vettel a further point behind. The Brawn GP team now leads the Constructors’ championship with 50 points, 22.5 ahead of Red Bull which holds second by just a single point from Toyota.

F1 now takes a two week break before returning to Europe where many teams will be introducing major updates to their cars for the Spanish Grand Prix in Barcelona on 10 May.
