There we go again! In this puzzle i played bf5+ which mates in 8 and got it wrong (-15) cause there is a mate in 4. Its annoying and uninspiring.

You did not find the BEST solution, puzzle rating points are useless, and you're an idiot for thinking otherwise.

Mate in eight, not too great. Mate in four, full score.

Tell that to those who decided that a victory gives you 1 point in a tournament, whatever the number of moves you've made ?

#3 I agree, they could give half the points or even a smaller fraction but dont take it full wrong
