  • The only difference between position A  and position B  is the location of one black pawn:  bPh4 and, respectively, bPh3! Still, to make this subtle change not less than 702 moves are necessary! 
  • Ivan Skoba writes that this problem was composed during ChessProblems.ca TT2 (it is similar to the 4th Place). Ivan also informs that his lecture at the recent 2nd International Chess Composition Festival in Marianka (http://www.goja.sk/soks/index_en.htm) was inspired and motivated by this tournament!

  • Ceriani-Frolkin SQ, Valladao, mate given by promoted piece.
  • The stipulation "pser-hdia N" means that, from the initial position, White plays N moves (with possible black parry-moves in between), followed by one Black move (just as in a ser-h# N, where Black plays N moves followed by one White move).
  • A perfect demonstration of the special role that the check-and-parry moves could play in combination with ser-hdia!
