Odredite u koliko najmanje poteza bijeli daje mat u sljedećoj poziciji (uz standardne pretpostavke u šahovskim zagonetkama: bijeli je na potezu, crni igra optimalno, broje se potezi bijeloga).
Odgovor zapišite u obliku N:prvi_potez, gdje je N broj poteza do mata, a prvi_potez je zapisan u standardnoj (algebarskoj) engleskoj notaciji.
Determine the least number of moves needed for white to checkmate black starting from the following position (assuming standard chess puzzle's rules: it is white to move, black plays optimally, we count white's moves).
Write your answer in form N:first_move, where N denotes the required number of moves, and first_move is written using standard (algebraic) notation.
