All players of a certain technical level know the typical sacrifices to break a castling. The most frequent is the one that begins with a bishop that immolates itself on h7 (or h2) to enable a checkknight jump to g5 (g4) and landing the queen on h5 (h4) with lethal effects. The deliveries of material are also relatively easy and frequent to force a tie by continuous check. But sacrificing two pieces in a row and winning is much more difficult because it requires a careful evaluation of various factors of the position; above all, the number and availability of the attacking and defending pieces.
Liren Ding (Wenzhou, 1992) signs an example as beautiful as it is instructive in the game of this video, with an extremely precise combination to get the most out of the elements that define the position. Third on the world list a month and a half after his title duel against Ian Niepómniashi, the Chinese star shows why he was the most feared rival for the champion, Magnus Carlsen, before the pandemic.
