Wesley So’s brilliant tactical idea

Featured is a round 7 game from the 44th Chess Olympiad held in Chennai, India between USA's Wesley So and Armenia's Hrant Melkumyan. The opening is Caro-Kann Defense, Two Knights Attack. About half the game is quiet development and maneuvering, however play sharpens immediately after Melkumyan's 17....e5. What follows is a brilliant tactical idea by Wesley So that can easily remind the chess enthusiast of old school romantic style combinations. Are king walks ever not enjoyable?
