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.

featuring in the 'immortal game' vs Torre with the queen 'sacrifice' 18.Qg4!!
A game which appears to be controversial, however:

Re: Beauty contest
correction (regarding a link 'featuring' the awesome RS gambit
while i mentioned this link
https://bdgpages.blogspot.com/2008/10/g ... ambit.html
only the title applies, the game featured there is Not the RS gambit,
but a French Henneberger gambit.
So a corrected link for the origins of the RS gambit
https://www.perplexity.ai/search/in-che ... kX_llBIw#0
Second correction, the Ziegler defense in the BDG was not named after Edwin Ziegler A,
but after an unknown amateur player who first used this defense against Diemer,
later analyzed more in detail by a certain Gunderam

Re: Beauty contest
game nr 31
With the awesome Urang Utan (Polish/Sokolsky) opening, 1.b4!, with a novelty at move 8.
Against an at least superGM level engine (Marvin) which nevertheless makes a critical blunder at move 42 in a defensive
position (time control 4/2), with the Black king under attack despite being a knight an three pawns(!) better,
Defending usually is more difficult (than attacking) for humans, apparently also for a lot of sub-top engines,
at least at blitz time control(s), as you can see in this game again.

PS in the next batch of games (after an update of the gambit book) i'll choose time control
5-3, to make such mistakes (as above for Marvin) more rare.
But first a few more amazing games.

Against an at least superGM level engine (Marvin) which nevertheless makes a critical blunder at move 42 in a defensive
position (time control 4/2), with the Black king under attack despite being a knight an three pawns(!) better,
Defending usually is more difficult (than attacking) for humans, apparently also for a lot of sub-top engines,
at least at blitz time control(s), as you can see in this game again.

PS in the next batch of games (after an update of the gambit book) i'll choose time control
5-3, to make such mistakes (as above for Marvin) more rare.
But first a few more amazing games.

Re: Beauty contest
nr 42 (the previous was 41, not 31 of course)
with a Sturm gambit, a relatively short game again for a change.
