Background and Bridge Info

I got started in bridge during early university days in the mid 1960’s; It was a Woman’s Weekly article that provided the impetus. Early bridge mentors were mother (a good player), Don Evans and Roelof Smilde. But having landed a lectureship in the Maths Department at Sydney University in 1974,  bridge took a second seat to my academic career.   During that time I was very instrumental in the development of the Sydney University Bridge Club where I helped to nurture many fine young players. The following names, from that time, may ring a bell or three: Warren Lazer, Bob Sebesfi, Fred and Anita Curtis, Peter Gill, Matthew Thomson, John Roberts, David Beauchamp, Jodi Tutty, Kim Neale, Kylie Robb, Peter Newman and Matthew McManus.

Professionally I was a University Medalist in Applied Mathematics, have a PhD from Cambridge University (same department as Stephen Hawking) and retired from the Maths and Finance Departments at Sydney Univer- sity as an Associate Professor in 2010. My book An Introduction to Exotic Option Pricing has now sold almost 100 copies!

Current interests include hiking (all over the world but slowing down now), golf, cruising (until covid struck), mathematical puzzles (I am a cubist of the Rubicks’ kind), reading (thrillers, spy novels and non-fiction), grand- kids and like many other bridge players I am a DA-tragic cruciverbalist.

I never really played that much bridge during my working life but since retirement I have played in most of the big national events. I foster long term partnerships ( a big advantage in my view) and apart from some minor excursions, have had only five partners in more than forty years of bridge (viz Fred Curtis, Peter Fordham, Bobby Evans, Henry Christie and Terry Brown).   I find bridge both challenging and stimulating and never cease to marvel at the myriad of permutations and combinations that appear at the table and how the smallest detail can lead to such amazingly different outcomes. With apologies to John H. Conway, I like to think of bridge as a “two-person game,  where each person consists of two people”. My most memorable and enjoyable victory in bridge was winning the Victor Champion Cup with my wife Kathy (and fellow wife- husband pair Cathryn Herden and Matthew Thomson) in 2015. I like to boast that I am married to an Australian bridge champion.

I was on the WBF Scoring Panel which introduced the new continuous Victory Point scales in 2013. The inclusion of two decimal points in the scales was initially greeted with horror and outrage. But some five years on, most players around the world seem to have accepted the new scales as a definite improvement. Personally, I would like to see a third decimal place in the VP scales, but am fearful of the backlash.

I have also had some technical input (of a mathematical nature) into the re- cent spate of cheating allegations, by assisting the European Bridge Union (EBU) in their prosecutions against a number of high-profile players. In the light of the outcomes, suffice to say that “mathematically” guilty and “legally” guilty are two completely different beasts. I am currently a member of the WBF Investigation Committee into on-line cheating.

Favourite deal: the one below featuring a double-backward (aka double- transfer) finesse, an invention of mine which was published in the April 2014 issue of the Bridge Bulletin of the ACBL.

After West leads the J, East takes the Ace and plays three rounds of Spades. Leave it to you to figure out the rest, but it involves Declarer first testing Diamonds then leading the J for a finesse against East, then the 9 for a second finesse against West and finally leading the 7 for a third finesse (of the ruffing kind) against East again – all to establish the 4!

Another curiosity occurred at the table in the final of the Asia Cup between Australia and Indonesia (Seniors) in 2014.

Q 9
  Q 6


I was sitting West defending their hopeless contract of 4 and we were down to the last three tricks with me on lead and declarer already two down. I realised that playing a Club would allow Declarer to ruff and I would only score the trump Ace. So I led the A and Declarer found himself in a quandary no-one seems to have seen before. If he played low from dummy, the next Spade would be won in dummy by force and they would find themselves with a Club loser. So Declarer unblocked the K under the Ace, but now the 8 forced Declarer to ruff with the Q and my J won the last trick for four down. I named this position the monarch squeeze because the position of the K and Q of trumps was critical to its success. Swap the K and Q and the ending just described fails to materialise.

Worst moment in bridge: losing the 2019 Open Interstate Teams by 0.8 Imps. With one board to go we were ahead by 0.2 Imps. Our South Australian opponent’s stopped in One Spade which Deep Finesse could beat but we couldn’t. That was 1 Imp out and the title
