Congratulations to Wesley So!

He delivered one of the most dominant #speedchess performances on record, vanquishing the talented Duda with a 20-7 score 😯

What a game one!

Jan-Krzysztof Duda pushes Wesley So to the brink with a huge mass of pawns! So narrowly saves a draw with his active rook against Duda's pawnslaught!

In game two it's Duda who escapes Wesley So as So's pawns advance!

Two draws so far but tons of excitement as Duda played multiple moves with less than one second on the clock

So wins game three! Duda sacs his queen to mix things up, but So finds all the right moves as White to put the game away and take a #speedchess lead! 👏

So wins another endgame as Duda can't quite muster enough counterplay despite putting up fierce resistance!

O.M.G! Soooooo many critical blunders! 🤯🤦

So and Duda exchange full points in the craziest 30 seconds in #speedchess history!
