Which Test captain was most often dismissed by his opposite number? Was it Sunil Gavaskar by Imran Khan? asked Gyanendra Singh from India
Sunil Gavaskar was dismissed five times by Imran Khan in Tests in which they were both captain. This equals the record for a pair: England's Ted Dexter fell to Richie Benaud five times, all during the 1962-63 Ashes in Australia. Gavaskar was also dismissed twice by Bob Willis during India's series in England in 1982, making a total of seven. But the leader in this regard is Clive Lloyd, who was dismissed by his opposite number on no fewer than nine occasions in Tests - four times by Kapil Dev, twice by Bishan Bedi and Tony Greig, and once by Ian Botham.

Benaud dismissed his rival captain on a record 18 occasions; Imran is next with 15. Jason Holder leads the way for current players - so far he has disposed of his opposite number 13 times.

Which Test players were nicknamed "Big Dog" and "Little Dog"? asked Denis Collinson from Australia
This was a famous pair of South African brothers - fast bowler Peter Pollock and the superb left-hand batsman Graeme Pollock. Peter, whose son Shaun Pollock also had a glittering Test career, explained the derivation of the names to the Gulf News a few years ago: "I was playing for Eastern Province, and was 17 years old. My voice hadn't broken. I appealed, and it sounded like a dog barking. Atholl McKinnon named me! When my brother came along, I became Big Dog and he was the Little Dog."

A recent question here mentioned the West Indian Faoud Bacchus, whose 19 Tests all came on different grounds. I noticed that when he made his highest score of 250, he was out hit wicket - was this the highest Test score to end this way? asked Dennis Johnson from Barbados
West Indies' Faoud Bacchus hit his own wicket after making 250 - his only Test century - against India in Kanpur in 1979-80. It's actually the second-highest score to end this way: the Australian opener Bill Ponsford hit his own wicket after making 266 against England at The Oval in 1934, in what turned out to be his final Test. There have been 12 other Test scores of over 100 that ended with a hit-wicket dismissal, including another one by Ponsford, in his previous innings - 181 against England at Headingley in 1934.

Who has scored most runs in one-day internationals as an opener? asked Rakesh Bhatia from India
Well clear here is a man who rarely opened in Tests, but adapted beautifully to the role in one-dayers: Sachin Tendulkar made 15,310 runs from the top of the order in ODIs. Sanath Jayasuriya comes next with 12,740, while Chris Gayle has 10,179. Adam Gilchrist and Sourav Ganguly also made more than 9000 runs while opening. For the full list, click here.

In Tests, Alastair Cook leads the way with 11,845 runs as an opener, ahead of Sunil Gavaskar (9607) and Graeme Smith (9030). For that list, click here. Gavaskar scored the most centuries as an opener, with 33 to Cook's 31.

What's the record for the most ducks in a Test? And an ODI? asked Billy Linklater from Ireland
If you mean the most ducks in an innings, the Test record is six, which has happened five times now, most recently when five New Zealanders failed to score against Pakistan in Dubai in 2018-19. The record for an ODI innings is also six, and has also happened five times, most recently by Pakistan v Sri Lanka in Colombo in June 2012.

The record for both sides in a Test is 11 ducks, which has happened 12 times now. The most in a one-day international is eight, in the World Cup final between West Indies (three ducks) and England (five) at Lord's in 1979.
