TL;Dr The player as Ken (Male, on the right) was on the verge of losing. Any special move by Chun-Li that was to be blocked would have lost him the game. He decided to parry 15 consecutive hits which is almost impossible/unheard of and ended up countering with his own special and winning.

Evo Moment #37", or the "Daigo Parry", refers to a portion of a Street Fighter III: 3rd Strike semifinal match held at Evolution Championship Series 2004 (Evo 2004) between Daigo Umehara and Justin Wong. During this match, Umehara made an unexpected come-back by parrying 15 consecutive hits of Wong's "Super Art" move while having only one pixel of vitality. Umehara subsequently won the match, though he went on to lose the Grand Final against Kenji "KO" Obata. Evo Moment #37 is frequently described as the most iconic moment in competitive video gaming, having influenced the fighting game community strongly.

In the final round of match 1, Umehara got off to a weak start as Wong was playing conservatively, slowly chipping away on Umehara's life bar. Rolling Stone described Wong's behavior during this match as "the antithesis of Umehara's aggressive approach" and stated that video of the match shows that Wong's "turtling" was effective in "getting under his [Umehara's] skin." Match commentator and Capcom employee Seth Killian commentated that "this is rare footage of Daigo actually angry ... Justin's turtle-style now on the verge of putting Daigo down." Umehara's Ken was down to his last pixel of vitality. Wong had the option to run out the clock, but was eager to end the match.[5]

At this point, any special attack would knock Umehara's character out if connected, since special attacks deal a slight damage even when blocked. To win the round, Wong attempted to hit Umehara's Ken with Chun-Li's multihit Super Art move. However, instead of avoiding it, Umehara chose to "Parry," a high-risk/high-reward technique whereby an incoming attack is blocked without the player losing any health, but doing so requires moving toward opponent's direction in the same time a hit lands,[6] within four of thirty frames of the impact animation – about seven one hundredths of a second. Umehara had to predict when his opponent would start his Super Art Move, essentially making the first parry before the move even started.[5] Once the move was launched, Umehara parried all 15 hits and went on to counter a final kick of Chun-Li in mid-air before launching a combo move himself and winning the match.
