that wasnt particularly hard to see
eval goes from -5.5 to + 5.9 at depth 22 with the initial move. the guys playing it were ~1700 and its just a huge blunder not sure how the puzzle scores are determined at all tho
@evilskeleton:
even if u dont see the diagonal coz u lack visualization u still see the rook skewer, so youll automatically make the right initial move and get the position on the board and by then u must realize the queens attack each other
