In memoriam GM-ICCF Werner Stern

Werner Stern recently passed away at the age of 86 years. Werner was a physicist by profession and lived in Bremen for many years. Werner played correspondence chess for more than 50 years and celebrated many successes; he was the first European Champion (individual) and achieved this title for a second time to become the 7th European Champion. Werner obtained the IM title in 1990, the SIM title in 2001 and gained the Grandmaster title in 2009.

In national championships, Werner became the 20th Veterans Champion of Germany (2002 - 2005)

Werner is the only player to have won the European Championship twice. The confident way, in which he won both tournaments is remarkable; in the first European Championship, he achieved 13,5 Points/14 games - 3,5 points ahead of the second and third placed players Risto Kauranan and H. Ernst. In the 7th European Championship, he again won with a remarkable 12 points/14 games (11 wins, 2 draws, 1 loss) 2 points ahead of the following players. In finale no. 28 Werner became Vice European Champions, only 0,5 behind the winner Janis Vitomskis.

Also in the World Championships Werner played many interesting and nice games; he won his group in the Candidates Tournaments of the 15th  World Championship and achieved a further qualification to Final in the 19th Candidates Tournament. Werner played two finals, ended in the upper midfield and played lots of wonderful games. He repeatedly beat top world-class players in an impressive manner.

We will always honour his memory. Rest in peace, dear Werner!

5th British Webserver Team Tournament


5th British WS Tournament - Division 1

8 games remaining and a tight finish with all bar one team still capable of achieving first place.

Stand game appears to be Rhodes- Relyea on Board 3

5th British WS Tournament - Division 2

The division has completed with the BCCA Kings and Civil Service A promoted and Natcor A and White Rose B relegated.

A most interesting game was Gareth Yeo' win against James Mansoon

5th British WS Tournament - Division 3

Lots still to play for with 16 games remaining. Schrach Dragons and Herts and Minds appear to have secured the promotion spots but could still be caught by the BCCA Rooks and BCCA Griffins. Cannon-Scott could well prove a decisive game

5th British WS Tournament - Division 4A

BCCA Tacticians secured easy promotion with a 90% score! Credit goes to Michael Farmer and JDM Tymms on 100% scores!

5th British WS Tournament - Division 4B

BCCA Cavaliers performed almost as well as BCCA Tacitians by scoring 85% with Pablo Mourjan and David Elwood also scoring 100%

Tournament Update: 2nd States and Regions

Despite the start date not being until the 1st of May, the play has been brisk with 8 games completed in the 1st Division and 34 in the Second. Unusually for modern Correspondence Chess over 50% of the games have been decisive.

The offer of Norms on all boards in this popular and well-received tournament seems to have prompted positive play and planning for the next renewal is underway, considering that enquires have already been received!

States and Regions CCC 2019 Division One

Still plenty of manoeuvring taking place. Stand out result so far is Sherwood - Vivante- Sowter 1-0, with some poison found in an off-beat Nimzo-Indian line, although still a while before this game becomes public! 

States and Regions CCC 2019 Division Two

Early days but Wes Wales Dragons (Jean, Scott, Denton and Smith) are  the standout team so far

States and Regions Correspondence Chess Championship

Season Two of The States and Regions Correspondence Chess Championship has now started.



There are two divisions, with 15 teams being in each division; title norms are available on all boards, ranging from Category Six on Board One of the First Division to Minor Category B on Board Four of the Second Divison, so we do hope to see plenty of title norms emerging from this event.

There are nine Welsh teams, four each from England, Cuba and USA, two from Austria and Slovenia, and one each from Denmark, Spain, Germany, Italy and Panama; so this really is an international event!

WCCF wish all teams and players the best of luck, and hope that everyone enjoys their games.

New Directions

This I write this feeling probably the best I have done for around a month – it's quite a strange virus that removes almost all energy and motivation and gives mild flu symptoms which last for weeks. Even more so when it affects more than one person! I can tell you its not fun when is coincides with a surge at work as well!

 Still, time to crack on and clear all the backlog!

Anyway back to Correspondence Chess. The last few months have generated quite a few interesting developments with regard to CC and Engines. These developments are, I believe, quite positive as well as having the potential to be quite disruptive to use Marketing speak.

I believe most people will have heard of Alpha-Zero and the advances this has delivered. This is covered in the excellent book “Game Changer” (In an in-depth review from a CC perspective will follow in April – let me clear the backlog first!).

Whilst AZ is very interesting and as I will cover next month, gives a number of insights very useful to the CC player, it is in itself not going to have a direct impact on CC for a number of years, it at all – why: because until the software and hardware become readily available it will not be within the realms of the ordinary CC player.

So discounting AZ, what is changing that is going to disrupt CC? If we consider a year or two ago the situation was, in a nut-shell a choice of Stockfish, Houdini or Komodo, with Stockfish the choice of the majority and the main difference between players being a combination of Hardware, Engine-wrangling skills and Chess knowledge, pessimistically probably in that order.

However, the situation has changed over the last year…..

  • LCZero: The development of the AZ inspired open-source engine and crowd-powered Networks has been truly amazing, with LCZero now being on par with Stockfish in typical engine tests.
  • Komodo MCTS: Whilst not as strong as Stockish, the Komodo teams efforts to bring an effective Monte-Carlo Tree Search to an AB engine have generated an excellent tool for the CC player.
  • Monte Carlo Tree Search: For many years the AB engine has ruled the roost (and still does in very rapid time controls) but the use of MCTS has flourished in the last year giving a previously unseen level of variety in move possibilities
  • New Engines such as Ethereal
  • Stockfish derivatives: A number of developments have taken place over the last year which are of interest to the CC player. Examples of this are:
    • The excellent Raubfisch , which continues to tweak its results upwards
    • Stockfish Cluster – an attempt to allow the running on massive hardware
    • ShashChess – A very interesting offshoot which adapts itself based on the type of position.
    • Sugar MCTS – a powerful implementation utilising a version of MCTS but also including a learning function.
    • Thothfish – a very new kid on the block but bringing two new very interesting features of a “Magic Tactic Solver” and more interestingly a way to manipulate analysis to swap or not swap certain pieces.


  • 7 Piece TB: These are now coming available for download. In reality, I don’t see anyone downloading the full set, due to speed and memory limitations but the downloading of specific ones can aid enormously.

Putting this together (and other advances I have not mentioned) we are now seeing a situation develop where there is more than “one horse in town” in the form of Stockfish, where these different approaches all have very similar performance in traditional testing (The flaws in this for CC I will cover another day!) but often give different suggestions in the same position.

The outcome of this is two-fold: Human input will become more important, the decision to take path A instead of path B, C or D and that this will lead to a reduction of the draw rate or rather more hard-fought draws at a minimum!

So a positive picture for CC? I believe so.

Anyway back to the backlog clearance, then onto launching EARG, writing the Engine and Introduction to CC Guidebooks!
