Two Queen Sacrifices

Until two days ago, Stephen Lewis, a member of Stowmarket Chess Club and Bury St Edmunds Chess Club, had never had the opportunity to execute a Queen sacrifice in a competitive game, but was very pleasantly surprised to be presented with two opportunities in two days this week.

Puzzle 1: Can you spot how White forces checkmate in 16 moves after hoovering up most of Black’s pieces?

Puzzle 2: White to play.
