well imo not such a 'completely' different approach (although such a video even
says more than a verbal auto-fritz analysis), the idea of this thread was
to present games in a similar fashion as games after a chess tournament
are rewarded with a brilliancy prize, so your game falls in this category,
so i give your game the nr 33.
Aa few small comments the move 2...f5?! is the (Old Benoni) 'Mujannah formation',
after which a gambit player could play the Old Benoni-Staunton move 3.e4!? The
king's attack with P5extr later in your game nevertheless was quite interesting.
PS tomorrow i'll probably list some Black wins (gambits/shorties)

Re: Beauty contest
nr 36, another win for Black in 21 moves. This time with the Albin (*) counter gambit.
https://en.wikipedia.org/wiki/Albin_Countergambit
With P5 Extr-Eas, and a rather weak opponent (club level) was chosen, so Whites makes a few inaccurate
moves, starting at move 6 nevertheless it's interesting to see how this is quickly punished by Black
with an awesome bishop sacrifice at move 13.

Re: Beauty contest
And now some White wins again,
nr 37
with the same amazing gambit move and novelty at move 3 (!) as in game 3.
This time not with 3...Nxd4, but the better 3...cxd4 Nevertheless a win again for White with P5, against
an IM level engine, Knightx slightly stronger than Rodin. At move 30 Black goes wrong, maybe because
of the relatively fast time control (4-2). And then the White win imo is impressive/instructive

Re: Beauty contest
nr 38
a (rare) Black gambit again for a change, with again a novelty at move 3, now for Black
Note that Marvin generally plays at, or above super-GM level, nevertheless it's
squashed by P5 within 28 moves. Note first that, whereas many conventional engines
would take back the pawn on b5, P5 is delaying this, and when Marvin plays b5xc6, it
wins a tempo with the knight going to c6.
The Black move 12...Bxh2!+ move in Greek gift style looks highly speculative (because there is no
knight on f6), but with the later rook lift Rf6 it becomes clear why it was a good (and at least not a bad)
move. Then later on, the White move 22 is a (severe) mistake, maybe because of the relatively short
time control (like in an earlier game with KnightX) it fails to see the following mating sequence.
