    I think i’ve got the solution. Can i write it here?

  2. Felix on 12 August 2007 21:16 PM

    Yes, I also did it and noone complained :)

    My try:
    1.f7
    a)1…Ra6 2.Ba3
    b)1…Rg8 2.fxg Kxg8 3. Ne7+
    c)1…Rf6 2.Bb2

    I also want to say something about last week’s study:
    Do you really think any human can solve this? :)

    1.f7 Ra6 2.Ba3 Rxa3 3.Kb2 and now
    1)3…Ra2+ 4.Kc3 Rc2+ 5.Kd4 (Kb4 Rb2 seems to be = because black can give checks on a2,b2 and c2, if the king goes on the d file the black rook will give a check on d2 and go to d8, if the king comes on the 7th rank, black plays Rb7 ) 5…Rd2+ followed by Rd8… =

    2a) 3..Ra2+ 4.Kc1 Rc2+ 5.Kd1
    2b) 3..Ra2+ 4.Kc1 Ra1+ 5.Kd2 (now there’s no Rd1+) Ra2+ 6.Ke3 Ra3+ 7.Kf4 Ra4+ 8.Kg5 Rg4+ 9.Kh6 Rg8 10. Ne7 and now either fxgR# or Ng6#.

    Ok, these are correct, but Felix, i think your b) point could be improved: 1.f7 Rg8 2.Bb7+ Kh7 3.fxg8Q+, because the bishop would be now on the a1-h8 diagonal and it would have more options. I agree with the other variations.

    I don’t think this makes a big difference :)

    Anyway, nice study, Kc1-d2-e3-f4-g5-h6 looks nice :)
