The computers at TCEC 10 tried the three pieces for the queen, but they don’t understand it; a human player with the Black pieces in this game would not cease hostilities on move 23. White does have a space advantage and the White rooks are well-placed, but it’s not until White gets the three connected passed pawns in the analysis that there is a chance to counter the inevitable swarm of Black pieces.
