"This charizard was the best card. It was my life back then," he recalled at the British judo team's training base in Dartford to the east of London.
"I've gone to grab his shirt and next thing I knew I was over his shoulder. I was a scrapper back in the day so I knew this wasn't right.
"I went for him again and as I've gone for him he's thrown me again. I was thinking 'No way, what's going on? How's he throwing me? He's hurting me'."
Baffled, he went home and looked on the internet where he discovered he had been overcome by a judo move. Keen to learn more, he went along to a local club and found his erstwhile attacker there, along with his Pokemon card.
