I felt like I played quite well and the computer analysis confirmed it. I was fortunate enough to be able to find the correct moves while using little time too, so I did feel like this game deserved a celebration. Regardless, Black found himself in a lost position very quickly, despite only making 2 inaccuracies, according to Lichess' Stockfish.
Enjoy the game. Cheers! :)
The game definitely deserves a celebration, in particular because it has some theoretical value. Black makes actually only one mistake in the game, with some other inaccuracies later in an already difficult position. The mistake is a novelty, which is shown to be a bad one.
8...Nh6 is not at all in the spirit of this system. There is a game Sorokin-Nenashev 1992 that went on 8...e5 9.a3 Nge7 10.b4 0-0 and Nenashev, a very strong theoretician (renowned for his Benko-beating skills, for example), went on to win with Black. It's one thing to know that the move cannot be good, it's another thing to play White and bust it convincingly. You managed to do just that. 9.d4 is the refutation of 8...Nh6, so we should credit you for the novelty :) .
Your opponent didn't need to help you a lot. One can criticize 15...f5 (instead of 15...Nf7) for letting you push e5 instead of reinforcing control of e5. Komodo definitely blames 16...Bb5 for making things easier for White (either exd6 immediately or what you do in the game). In a lost position, Black makes the last mistake with 18...Nf7? (instead of Nc4, still losing, but slower). Honestly, these moves just make the game shorter.
I'm surprised that Stockfish doesn't say anything about 15...f5. According to my Komodo, this move is responsible for tilting the assessment from "big advantage for White" (+1.15, the 75% threshold) to "winning for White" (+1.65, the 90% threshold).
Congrats for the "TN" refutation !
@A-Cielbleu First off, thank you very much for the kind words :) And the excellent analysis.
8.Nh6 is definitely not a very good move, but this kind of maneuver with Nh6, f6 and Nf7 makes sense in some slower variations of the Rossolimo. Perhaps this is a case of knowing the opening too narrowly and playing it schematically.
Since 15...f5 it went seriously downhill and he didn't manage to stop the snowball effect...
Analysis
lichess.org/study/MPFsWGMU Opponent played very badly
white 18 centipawn lose ( white don't play best moves at blitz game)
Edit white wins because white find tactic and play active
Amazing game, I am learning to play this line myself and i think this is an excellent model game!
i was shocked to see the f6 move surprised the computer doesn't criticize the move more than that
white has already such a positionnal advantage that black has hardly any usefull move
