I gave the game to Grok 4, and here is Grok 4's guess.

White is around 1800 Elo, while black is around 1600 Elo. The opening is handled reasonably by both sides with an understanding of aggressive themes in the Sicilian (transposing to a Najdorf-like English Attack), but the middle game features several tactical oversights, inaccuracies, and blunders—particularly black's queen maneuvers leading to its loss after 31...Qa1+ without seeing the opened first rank. White's sacrifices show creativity but are flawed, and the mating sequence is sharp but aided by black's errors. This level of play suggests intermediate-advanced amateurs who know theory but miss deeper defensive ideas.

Very close.
