So please post your results! > >Jeroen You start with line 8 You start by a8 there is a black rook there so you write small r (white pieces get big letters) b8,c8,d8 have nothing. The number of this squares is 3 so you write 3 e8 has black rook on it so you write r f8 has nothing(1 square) so you write 1 g8 has black knight so you write n h8 has black king so you write k You write / because there are more lines. result for line 8 is r3r1nk/ by similiar way you calculate results for line 7,6,5,4,3,2,1 pp3bb1/2pq1p1p/5Pp1/1P1PP3/2B3N1/P1Q3BP/1R3R1K you add w - - 0 1 and get the following string (w is for white to move) I added [D] behind it to get a diagram. [D]r3r1nk/pp3bb1/2pq1p1p/5Pp1/1P1PP3/2B3N1/P1Q3BP/1R3R1K w - - 0 1 26.e5 is the move to find. After 26.e5 dxe5 27.f6 movei in anlysis mode can understand at depth 11 that black has significant problems so it seems clear that finding the moves is only a question of time for it. It suggests 27...Bf8 with more than +1 for white at depthes 11,12. Uri
