The Don, Gilly and a man called Pistol

I know that The Don once scored 309 in one day, but how many runs did his team make that day? Is it the highest number of runs ever scored in one day of a Test match? asked Prashant Venkatesh from India

Don Bradman made 309 not out on the first day of the third Ashes Test at Headingley in 1930, still the record for one player on any single day of a Test (Wally Hammond comes next, with 295 in a day against New Zealand in Auckland in 1932-33). Australia finished with 458 for 3 on that day in Leeds, which rather surprisingly is only 19th on the list for most runs scored in a day. Top of the pile comes the second day of the Old Trafford Test of 1936, when England and India made 588 runs between them - England took their overnight score from 173 for 2 to 571 for 8 before declaring, then India raced to 190 without loss by the close. The three-day match finished in a draw. For a list of the highest run-totals in a day's play in a Test, click here.

Adam Gilchrist played in 96 Tests, and apparently kept wicket in 191 innings - one fewer than the maximum 192 in which he could have done. Given that Australia never lost a Test by an innings during Gilchrist's career, what happened on the 192nd occasion, and who kept wicket in his place? asked James Williamson

The match that mucks up the calculation came quite early in the stellar career of Adam Gilchrist. It was the second Test against New Zealand at Hobart in 2001-02. Rain ruined the match, which was left drawn, and New Zealand only batted once.

The recent tie between New Zealand and England was apparently the highest-scoring tie in ODIs, but what was the lowest-scoring one? asked Solaiman Palash from Bangladesh

That match at Napier last week was the 23rd tie so far in one-day internationals, and the totals of 340 were indeed the highest in any of those games. The lowest score that resulted in a tie in an ODI was 126, in the match between India and West Indies at Perth in 1991-92. For a full list of tied ODIs, click here.

Which ex-player's autobiography is called Inside Out? asked Anish from the United Arab Emirates

This was a difficult one to track down, but the first book I could find of that name turned out to be the autobiography of the Australian fast bowler Paul Reiffel. It was published by Harper Sports in Australia in 1998. "Pistol" Reiffel played 35 Tests and 92 ODIs - his last international match was the World Cup final at Lord's in 1999 - and is now an umpire. Inside Out was also the name given to the autobiography of the former Pakistan captain Mushtaq Mohammad, which came out in 2006.

Is it true that Steve Waugh played for Ireland? asked Ram Shankar from India

Yes, it is. Steve Waugh played a few matches as Ireland's overseas player in 1998, against the touring Australia A side. That included one first-class match, in Dublin (Waugh made 31 and 45), and some one-day games, in which Waugh made 67, 50, 0, 17 and 36.

Is the England woman cricketer Jenny Gunn any relation to the famous men's Test-playing family, who were also from Nottingham? asked Gavin Stevenson

According to Cricinfo's own Jenny Thompson, the Nottingham-born Jenny Gunn, who is currently playing for England in their ODIs in New Zealand, is not related to the famous Nottinghamshire Gunn family, which provided three England players in the early days of Test cricket - William Gunn, who also played football for England, his nephew John Gunn, and John's younger brother George Gunn, who scored a century on Test debut in 1907-08 and played his last Tests in 1929-30, when he was past 50.

"With reference to last week's column, I'm afraid the Brisbane tailor was George Symonds, not Roy. For some reason I had the idea the nickname had something to do with the old comic strip Roy of the Rovers, but that is probably completely wrong," says John Biddle from Australia.

There's another explanation from Abhishek Bhardwaj in India: "The nickname actually originated from the book Primal Fear. The story goes that Symonds liked the book very much and the book was also a favourite of the previous coach, John Buchanan. The protagonist of the novel had the name 'Roy' and so Andrew got that name."

But there's an alternative explanation from Wendy Hull in Australia: "I have always thought Andrew Symonds was called 'Roy' after Roy Rene (Mo), an Australian comedian who painted his face black and white. The Mo Awards are named after him. Symonds obviously doesn't use the white 'paint' on his lips solely as sun protection, as he wears it at night, and when he's playing at the Telstra Dome in Melbourne when its roof is closed."
