Beauty contest

[jefk]

then i have to assemble them again, from different 'interesting-win' files,
would be some 'work'; copying/pasting from this forum maybe should be possible
but i haven't found out yet how to do it (maybe someone else knows?)

So finding the games again from my various files, would be some work;
could do that later, if you really would like that
eg. when reached 40 games or so.

and then you can remind me

nr 26, a Clemenz opening again.

Seeing such games i'm a bit surprised Rebel Extr. isn't rated higher (P5 seems to have about

to perform just as well)

Survivor bias in the game collections

[jefk]

CW 'survivor bias' well sure there's a bias because those games were selected
with the Pohl tool, finding (very) interesting wins (as i wrote earlier).

So ok, P5 is stronger, next batch of games will be mostly P5 again.

So now another awesome game, nr 28
with a Bird opening, transposing to a delayed Sturm gambit (declined) with the move 3.c4!
Rodin declines the gambit (normal move order(*) 1.f4 d5 2.c4!?)
https://www.chess.com/blog/LimeLime1/th ... rms-gambit
but then gets outplayed anyway:

in QGA style btw

continuing, first with some shorties, then with some big sacrifices again;
and as usual mostly with awesome gambits (and sometimes a novelty)

game nr 29:
For a change not with Patricia(5), but simply with a top engine,
possibly playing the gambits better than SF when in Tal mode:

More about this awesome (Boden-Kieseritsky) gambit:
https://www.ianchessgambits.com/boden-k ... ambit.html

Lionel Kieseritsky (1806-1853) also is known for several other gambits,
mostly in the King's gambit, still being highly popular during those times
https://en.wikipedia.org/wiki/Lionel_Kieseritzky

Samuel Boden (1826 - 1882) was an English chess master, known for the Boden's mate:
https://en.wikipedia.org/wiki/Boden%27s_Mate
imo he looks a bit like Morphy

game nr 30
With Shashchess again for White (and Rodin with Black). With a Sicilian wing gambit (again),
a similar game had been posted earlier but this one is different again,
A short game, and also with quite some sacrifices by White.

A short game again, with P5extreme, inspired by a Pohl posting. P5extr isn't as
strong as the usual Patr5, so i've let it play against some weaker engines,
at approx club players level; with some interesting results.

In the game below, i call the rare move 3.Qe2!? in the French the Zvjaginsev
variation, after the -relatively young- GM Vadim Zvjaginsev.
https://en.wikipedia.org/wiki/Vadim_Zvjaginsev
In that line, after the usual 3...dxe4 there is a known gambit with 4.f4?! the socalled
Hoffmann gambit, probably named after FM Asa Hoffmann
https://en.wikipedia.org/wiki/Asa_Hoffmann
Not occurring in my database btw, so it's an extremely rare gambit, and imo not so good;
better are three new 'Djengis' anti-French gambits with 4.c3, 4.Nc3, or 4.Nd2.
In the game below 4.c3! was played, with a quick win for White as result.

White had a quick win after the mistake 12...f5? . But after the correct move 12...Qh5
we still would have an interesting game.

My small contribution to the beauty of Patricia, complete different approach...
