Well, a John was always going to win. From the score sheet, it can be seen that John McL made a good start, 1-0, 3-0, 4-0 to 7 points, a very good start indeed. But as we know in this game, a good start means not a lot. John P finally scored and again and again 4-1, 4-1, 4-4. If your opponent can win 3 games straight, then so can you, irrespective of the core.John P then powered ahead 6-4 and finally 7-4. Well done .... JOHN PAPADOPOULOS.

So we have GOLD - SOTO PHILLIS, SILVER - LAKIS KALEAS and BRONZE - PETER GIATZIS.

This was an interesting event because not everyone played everyone else. A draw was done so each player played 3, 5 point matches, without the cube. So you can imagine that up to 9 games could be played for an outcome and all to be played and finished on the night.

It is worth noting that GOLD MEDALLIST - SOTO PHILLIS was a late substitute for George Bourtsouklis so it was fated.

The order of merit for BASA players were, with 3 wins - SOTO PHILLIS, with 2 wins - CLAUDIE TROMP, JACK CLARK & JOHN McLEAN, with one win - NICK BEGAKIS, ANGELO ALI & CHRIS BENHAM and without a win SIEGFRIED POHLENZ.

The order of merit for the TAVLI team were, with 3 wins - LAKIS KALEAS, with 2 wins - NICK PAPADOPOULOS, PETER GIATZIS, and TONY KARAPETIS, with one win - JOHN PAPADOPOULOS, CHRIS PYROMALLIS and PETER ATHANASOPOULOS and without a win JOHN GIOUZELIS.

And as to which team were decalred 2008 OLYMPIC CHAMPIONS, amazingly enough [as calculated on the number of wins alone], each team scored 12.
So it is a draw but calls have been made for a repeat in 2009.

Many thanks to JOHN O'GRADY who engineered the draw and made sure we ran on time.

2008 SPRING TOURNAMENT UNLIMITED CONSOLATION TOURNAMENT WINNER This was as reported, CHRIS BENHAM and the above photo shows a happy Chris with his medal trophy.

07 Nov 08 - Melbourne Cup fever was still running strong at the Hilton and it was not until about 8:00pm that the revellers left us in peace. In the midst of all this fun and noise ; SIEGFRIED POHLENZ defeated JOHN O'GRADY in the October knock out tournament and in spectacular fashion last Tuesday 4/11/08. After winning the first game and then losing the next 3 to go to 3-1 down, it all went pear shaped for John O'Grady with Siegfried winning the next game [and the 7 point match] and scoring 8 points to win 9-1. See the attached score sheet.

In the Unlimited Buy Back as part of the Spring Tournament held 2 November 08 had 32 entrants and was finally won by ; CHRIS BENHAM from SIEGFRIED POHLENZ. Finally, our photo is not of the 3 amigos, not of the 3 tenors but of the 3 winners, Jack, John and John. Well done guys.

17 Apr 08 - Attached are some "happy snaps" of the 2007 Club Champion - Vassilis Toubakaris [L] and runner-up Chris Benham. Also we have a photo of the April 2008 Knock-out Tournament with winner Theo Georgiou [R] and runner-up Chris Benham. Players may find the following site interesting, I certainly did. www.piphit.com Good to see Henry Nurse pop up a week or so ago. And as promised, we publish Chris Benham's [the 2008 SA OPEN Finalist] review of Paul Weaver's [the 2008 SA OPEN Champion] book. Paul knocked out Chris in the final. Many thanks to Chris for his work. Enjoy.

Review of "Backgammon Openings (Book A)" by Paul Weaver and Nack Ballard, 2007.
by Chris Benham

This book is all about how to play the roll 3-1 on moves 1,2 or 3. Also there is an excellent explanation of the relative merits of the five point versus the seven point, which mentions some rolls besides 3-1. All the reasonable options are discussed and the explanations are excellent. The default situation is "money" or players are level in a match with cube in middle and the players are say four or more points away from winning. In some special match situations the best play is different, and these variations are explained.
From the explanations we can infer big hints on how to play similar rolls in similar situations. (In other words the concepts discussed don't only apply to the roll 3-1.). The findings are based on exhaustive rollouts by very strong playing/analysis computer programs ("bots") like Snowie and the excellent free GNU Backgammon. Only two of the 3-1 opening reply recommendations given in the article linked below differ from those in the book.

http://www.bkgm.com/openings/replies.html

When the opening play is 63:24/15 and the replier's match situation is "Gammon Go" (i.e. is greatly helped by winning a gammon but losing one is no worse than losing a single game) then the book says 31:13/10*,24/23 is best (while the rollout quoted in the article says 31:13/10*/9).
When the opening play is 62:24/16 and the replier's match situation is "Gammon Save" (i.e. losing a gammon is worse than losing a single game but winning one is no better than winning a single game) then the book says best is 31:13/9* while the article says that best (by an insignificant margin) is making the five point.
The rollouts on which the book are based were much more thorough than those used for the article, so I prefer the book's answers. Also the book gives replies for some unusual opening moves that the article ignores, like 6-2 and 6-3 played by moving both back men. Plus to explain concepts the article discusses one or two very-unlikely-to-occur "reference positions".
I missed the first part of Paul Weaver's lecture at the start of the SA OPEN, so at a few points in the book I was wishing that it also covered the other way to roll 4 pips, 1-1.
The book is physically a good quality hard-back, and I didn't find any errors (spelling etc.). I found the price of the book to be very reasonable value.
It can be ordered from http://www.nackbg.com/buynewbook.htm Some other good books can be bought from http://www.fortuitouspress.com/

11 Apr 08 - STOP PRESS - 2007 CLUB CHAMPION - VASSILIS TOUBAKARIS

VASSILIS TOUBAKARIS defeated CHRIS BENHAM
to be the
2007 SA BACKGAMMON ASSOCIATION BACKGAMMON CHAMPION

Original text by Club Treasurer, John O'Grady with embellishments by Club President, Nick Begakis

Vassilis Toubakaris defeated Chris Benham 3/9, 9/8, 95. Chris won the 2007 first half season by defeating Chris Benham in the final. In that first half season, Chris came from 4th place to defeat 5th placed Theo Georgiou and first placed Nick Begakis. Vassilis came from 6th place defeating 10th placed Claudie Tromp, 3rd placed Siegfried Pohlenz and 2nd placed Nick Papadopoulos.

In the second half season, Vassilis again was in 6th place and won through to the final by defeating 7th placed Theo Georgiou, 3rd placed Claudie Tromp and 2nd placed Louis Kalogiannidis. His opponent, Siegfried Pohlenz came from 5th place defeating 9th placed Emmanuel Lavrentiadis, 4th placed Nick Papadopoulos and 1st placed Angelo Ali. And of course, Vassilis defeated Siegfried in the final to again play Chris Benham.

And it is interesting to note that none of the top 3 in each season half made it through to their respective finals.

The final - played 8/4/08, in the best of 3, 9 point matches played [see attached score sheets], the first match went Chris's way with Vassilis only managing 3 points. Interesting to see gammons [2 point games], gammons with the cube on 2 [4 point games] and backgammons [3 point games] featuring on the score sheet.

The second match was as close as it gets. First 2 points to Vassilis, 2 to Chris. One to Chris, one to Vassilis. Two to Vassilis, two to Chris. One to Chris, one to Vassilis. Six all. Then 2 to Chris, one to Vassilis in the Crawford game and it is 8/7 Chris's way. But that was it for Chris and Vassilis scored a further 2 points in the next game to win 9/8. So, one all in matches.

In the decider Chris lead early with 4 points in the first game, 4/0 to 9. Vassilis responded by his winning 4 points too. 4 all. Chris takes one - 5/4.Then Vassilis wins a further 4 point game taking his score to 8/5 with the Crawford game ahead which Vassilis won.

So Vassilis is the new Club Champion, taking over the mantle from 2006 Club Champion Angelo Ali.

Well done VASSILIS TOUBAKARIS, 2007 Club Champion.
