In this episode of Underdog, Robert Ris presents two entertaining blitz upsets from a strong event in Sofia. First, Jolanta Zawadzka punishes former 2700 player Ivan Cheparinov with a sharp kingside attack in a Sicilian, finishing the game in just 20 moves. The second example features José García Molina against Sanan Sjugirov, where White sacrifices material for a dangerous initiative and builds a powerful attack against the black king. Both games show how quickly even very strong grandmasters can come under pressure in blitz when tactical threats and initiative take over.
