In a classic case of counting your chickens and all that, one of the competitors at this years EVO, The Largest Fighting Game Tournament in the World, has learned a hard lesson after being a little too caught up in his win.
This years winners bracket semifinals of the Guilty Gear Xrd tournament had come down to a battle between Woshige (as Millia) vs. Ogawa (as Zato), with Woshige the underdog and Ogawa the heavily favored victor. When Woshige took what he thought was the win, he leapt to his feet and began to celebrate, but the score was only 1-1. As the final round started Ogawa showed no mercy and quickly decimated a large chunk of his opponents health right away, by the time Woshige had realised his error the match was practically over, with his character stunned all he could do was watch as Ogawa took the victory and eventually the 1st place in the tournament.
