Morpion Solitaire - List of the site's news added February 15th 2010

• On the original 5T game:
• NEW RECORD by computer, with 145 moves by Haruhiko Akiyama Feb 4th 2010, one more move than the previous record done by computer.
  
       Even if it is an excellent result, the old record of 170 moves done without computer by C.-H. Bruneau in 1976 remains far from beaten
• Charles-Henri Bruneau's original letter of 1976 found in Pierre Berloquin's archives! Including his handwritten grid of 170 moves which is still today the world record.
   
• New page on the first record grids of 1972-1975, from 149 to 164 moves. Some of these old grids had never been published! Many thanks to Pierre Berloquin for his archives, and Bernard Lemaire for his information on Charles William Millington the author of several record firsts (149, 152, 163 moves).
• More than 800 million grids generated at random by Jean-Jacques Sibilla
• Misleading results in my search of the lost grids of 176, 179, 233 moves, grids announced -but not published- in 1982 by Jeux & Stratégie. Thanks to Michel Brassinne, Jacques Erb and Bruno Moret for their testimonies.

• 5D game: second record grid of 80 moves found by Tristan Cazenave
• Some historical precisions on the origins of 5D/4D/4T games, thanks to Stefan Langerman for his testimony

• 5T in a square, a variant played by Richard Cotté in 1970
