Viktor had a plan. He was tired of never having Hermione to himself in the evenings after classes. Weasley was always hanging around, whinging about his unfinished homework.
One night in March, Viktor challenged Weasley to a Wizard Chess game. The wager was an embarrassing one for Ron; if he lost, he would have to admit he fancied Hermione and provide Viktor's choice of sweets from Honeydukes for a month.
Viktor knew Weasley considered himself the Hogwarts Wizard Chess champion; it was going to be easy. Before the game started, Viktor surreptitiously sprinkled catnip all over Weasley and used a bit of Wandless magic to make Weasley temporarily allergic to Crookshanks.
The ensuing hilarity entertained everyone who was watching the extremely unequal game. Ron couldn't get Crookshanks to leave him alone, with the cat crawling into his lap just as he was ready to make a move. That set Ron to sneezing repeatedly.
Finally, Ron had made so many ineffective moves that Viktor checkmated him. Ron now had to buy the Bulgarian seeker Cinnamon Sugar Quills for a month and tell Hermione he fancied her.
