White to move and win
I don't often get to use this tactic myself, so it was nice that after blundering a piece in a recent blitz game my opponent was kind enough to grab my pawn on b6, leading to the position below.
Rd8+ wins either a queen for a rook, or just a rook. My opponent chose Kh7 and lost material after Qxb6 Rxb6 and Rxa8.
Despite my refusal to learn it in the past, this is a good tactic to know.
