Puzzle #277 solution:
Game Ferarini – Moresi, Italy 1972. Coco provided the best answer of the week and possibly of the year:
"a) White should play ahead because in chess games:
1. You never know if the opponent will blunder. Take the chance and sacrifice at the cost of drawing or winning!
2. White has the privilege to move first and also has many useful pieces that can begin an attack ( queen, bishops, rooks etc.), while black has a lack defending (too focused on attack)
3. Black's king is also in the corner like white's
