The encounter at Estadio Akron in Guadalajara started cautiously, with both sides struggling to create clear-cut opportunities during a tightly contested first half. Despite enjoying more possession, South Korea found it difficult to break down a disciplined Czech defence, and the teams went into the halftime interval deadlocked at 0-0.
The match burst into life after the restart when Czechia took the lead in the 59th minute. Captain Ladislav Krejčí rose highest to power home a header, giving the Europeans a surprise advantage and putting South Korea under pressure.
However, the Asian side responded brilliantly.
Just eight minutes later, midfielder Hwang In-beom restored parity with a composed finish after a clever attacking move. His goal injected confidence into the South Korean team, who began to dominate possession and push forward in search of a winner.
Their persistence paid off in the 80th minute when substitute Oh Hyeon-gyu completed the turnaround. The forward finished off a low cross from Hwang In-beom, sparking celebrations among the South Korean supporters and sealing all three points for his country.
Hwang In-beom was undoubtedly the standout performer, scoring one goal and providing the assist for the winner. South Korea captain Son Heung-min also played an influential role in attack, while goalkeeper Kim Seung-gyu produced important saves late in the match to preserve the lead.
The victory marks South Korea's first World Cup opening-match win since 2010 and continues their impressive record against European opposition on football's biggest stage.
Final Score: South Korea 2-1 Czechia
Goals: Hwang In-beom (67'), Oh Hyeon-gyu (80') – Ladislav Krejčí (59')
