  2. Sorry, I made an error in the notation. It should be:
    17+ (Peltier*-RichardsFink)
    1(18)1[2-9], 1(19)18[10-13]
    10(20)19, 13(21)20
    10(22)10[11,12], 22(23)13
    13(24)21, 23(25)24
    14(26)14[15], 14(27)26

    Also I got turned around on the graphic, it shouldn't have any gameplay effect as the spots are not numbered.

  3. Yes, correct notation for your move should tell on which side of the loop you make your pivot with @ qualifier:
    14(27@16)26, and yes not numbering spots has many advantages! :)

  4. Aha! So that's how you use the @. Makes sense now.

    17(30)28,

    Do you use "same parity of cannibals and survivors" rule to detect P-regions (of nim value *0)?

    10(22)10[11,12], 22(23)13
    13(24)21, 23(25)24
    14(26)14[15],14(27@16)26
    16(28)16[17], 27(29)16
    17(30)28, 2(31)4

    I'm not sure -- I don't really have a handle on the math and terminology. I do know that just playing this game at this level is changing how I play.

  7. Reading "Socratic Tutorials" is both entertaining and instructive... http://www.wgosa.org/soctut1.htm

    10(22)10[11,12], 22(23)13
    13(24)21, 23(25)24
    14(26)14[15],14(27@16)26
    16(28)16[17], 27(29)16
    17(30)28, 2(31)4 --> shouldn't this be 3 ?
    7(32)7[8,9] --> then I should rewrite it 4(32)4[5,6] if spots are born in ascending order...
    Feel free to number them in the most convenient way for your drawing.
