While we're closing in on an endgame, the position is not without danger for either player. Caruana has managed to gain a solid pawn structure, while Duda has a passed pawn in addition to being up the exchange.
Anything can still happen in this game!
Caruana prefers keeping queens on the board, as trading down to a queenless endgame could give him issues due to Duda's strong pawn on the queenside.
As long as Caruana can avoid this trade, he should be able to get some attacking chances against Duda's exposed king.
Duda goes wrong, leaving his queen offside! Caruana's attack may now become very dangerous, as Duda's queen cannot defend the threats against his king!
Duda is forced to give back his extra rook to avoid a deadly attack. Allowing this may have been a mistake from Caruana, however, as Duda gets his queen back into the game!
A huge blunder may decide the game! Duda can now trade off queens, allowing him to march his passed pawn up the board!!
Duda forces the trade of queens, allowing him to regrab Caruana's queen with check and creating an unstoppable threat with his passed pawn on the queenside!
A gigantic blunder from Caruana completely turned the tides as a single misstep allowed Duda to force a win by trading queens, and he is knocked down to the loser's match!
While Caruana managed to seize the advantage in a tricky endgame by trapping Duda's queen on the queenside, Duda managed to avoid a checkmate attack by the skin of his teeth. Failing to find a way to seal the deal, Caruana instead opted to grab material, a mistake that ended up being fatal for his position. Duda's massive comeback in this game ensures him a spot in the winner's match, where none other than Magnus Carlsen awaits him.
