This is a surprising game in my opinion and reveals how weak the MCGP2024 is in defending against King-side attacks.
All was about level until MCGP2024’s 19th move and then it lost in dramatic style!
In the following position Maia with the white pieces has a massive King-side attack whilst Black’s pieces are in the side lines:
Here the MCGP2024 moved 20…e5?? It has no fear! But 21.g6 and it would have soon been all over. However, Maia did not see this move but the end result is the same and a checkmate in only 27 moves.
