WRONSKI DEFENSIVE FEINT - DANGEROUS SEEKER DIVERSION
-- Message inside Harry's omnioculars (GF8)
References from the canon
- Viktor Krum pretended to dive towards the Golden Snitch during the Quidditch World Cup in 1994, but in reality he was using the Wronski Feint ploy to make his opponent Aidan Lynch slam into the ground, becoming "flattened" (GF8). Krum continued to fly around searching for the Snitch while Lynch was revived with an unnamed potion by mediwizards.
