But the session was all about the 22-year-old Kanpur boy.
Earlier, Kuldeep received his test cap by former leg-spinner and current commentator Laxman Sivaramakrishnan as India chose to go in with 5 specialist bowlers for the decider in Dharamsala.
If Australia record their second Test series win in India since 1969, Smith will nearly certainly be named man of the series.
Smith and David Warner were past their individual fifties and the century-plus partnership was looking ominous for India when Kuldeep employed the trick he had learnt from Warne to lead India's second session fightback. "I showed him the wrong one first, and then bowled him with the chinaman", said Kuldeep, whose best first class figures are 6/79.
Shane Warne has played an unwitting hand in Australia's struggles in the fourth cricket test against India.
Speaking more about his interaction with Warne, Kuldeep said: "Warne is my idol and I have followed him since my childhood".
"Dream come true for me. He has promised that he will have another session with me in near future", he added.
Deulofeu happy at Milan despited Barca interest
Barcelona's technical secretary Robert Fernandez hints they could re-sign Gerard Deulofeu for €12m. He has completely ruled out a return to Everton after his loan spell at the Serie A side ends.
Going into the final Test, the hosts will be hoping to have a 100 percent fit captain Virat Kohli after the shoulder injury he suffered during the third Test in Ranchi. I did exactly what he told me to do.
While he was a fan of Akram in his younger days, Kuldeep started to appreciate the art of spin bowling once he started bowling chinaman himself.
Smith has now made seven centuries in his past eight Tests against India and, while his batting might provide a blueprint for his team-mates, it's questionable whether any of them could perform at the same level as their captain in his current form. "They weren't overexcited. It was no different, to be honest", he said.
"All four wickets are special but I guess the first wicket (of Warner) was important from the team's point of view", Kuldeep said. "I don't bowl like that but I did not want him to know what I was bowling", said Kuldeep.
"It took a few balls to get used to him". However, he found his groove after lunch when he bamboozled the Australian batsmen left, right and centre. Keeper-batsman Matthew Wade's (57) rear guard effort stemmed the rot after the middle-order collapse with Australia managing to reach 300-run mark.
The extra bounce also helped his cause as Warner after doing all hardwork tried to play a cut shot close to his body only to find that the delivery bounced wee bit more to take a thickish edge to Rahane at first slip.
