Problem from a championship game
  • ypercube ★ at 2006-12-20

    Position taken from championship game between graff and ypercube: Game 629829, after move 13, Red throws a 3.

    Where is his best move and why?

    What are the Red's and Blue's winning chances? (for this round)

    1.[163425,163254] 2/b4-c3 2.2/e2xe3 3.1/a5xa4 4.5/d2xc3 5.4/c5-c4 6.3/c1-c2 7.4/c4-d3 8.5/c3-c4 9.5/a3-b3 10.6/d1xc2 11.6/b5xc4 12.5/e3xd3 13.5/b3-c3

    I'm quite sure the played move 14.3/c2xc3 is the best.

    Blue should then take the 2, although it will make the red 1 a very strong defender giving red plenty of time to win.

    Concerning the other move: 14.3/d3xc3

    From red's point of view having the red 2 on the board keeps the red 6 relatively slow. Moreover the red 2 has to watch out it doesn't walk into a zugzwang situation when it is captured on b4!

    Nice position.

    14.3/c2xc3 15.2/c4xd3 16.5/c3-c4 17.5/d3-e2 18.2/e1xe2 19.6/a4-b4

    In hindsight the previous move 13.5/b3-c3 was bad.

    Blue should have captured the red 6 on c2 and run for it with a good chance to win.

    I have had a interesting Position too. It took such time to decide the move.

    Red throws a 4. What do you think? What is the best move?

    33.[364125,153264] 6/b5xc5 34.6/d2-c3 35.4/a5xb4 36.2/e2xe3 37.6/c5-c4 38.1/e1-e2 39.5/a3-b3 40.6/c3xc4 41.5/b3-c3 42.4/c1-c2 43.1/a4-b3 44.4/c2xc3 45.1/b3xc3

    46.4/e3-d3 played, ok. 46.4/e3-d4 seems slightly worse.

    46.4/e3-d3 47.4/b4xc4 48.1/e2-e3 49.4/c4xd3 50.4/e3xd3 51.5/c3xd3 52.6/d1-c2 53.1/d3-e2 54.5/c2-b3 55.3/e2-e1

    Well-played game. There wasn't much you could do with the dice you got, except perhaps 38.1/e1xd1 in stead of 38.1/e1-e2. Still Luise R. would have kept the advantage.

    A interessting position, because it is clere that blue wins the game 6 moves befor ends. Even just the dice roll for blue. And not because blue is movin so clever…

    I have had that not very often.

    Actually the chance of RED winning is not 0 but 1/9, which is more than 11%,

    because red has to throw two additional 5or6-es to win.

    ??

    Blue has 1 stone (ein Stein), so there's no roll.

    Now I know how the game got it's name :) It's obvious, but I didn't see it until now.

    Ahhhh yes… i saw my mistake after sending the message.

    Jepp, you are right, but i mean the dice rolls “for” blue, not “from blue”. Red rolls a 6. That was what i meant.
