Beauty contest

[jefk]

which tool(s) ?

well Ed, by far most of the annotation(s) were done with Fritz19; full analysis with comments, 2 or 3 s per move.
To see if it's an interesting game, i usually first look with Chessbase 18 (report, novelty seeker);
which goes quite fast nowadays, and besides the novelty it then also list the predecessor game.
Sometimes i throw in some extra ! or so, or a small additional comment (eg at a critical moment)

Time for a Black gambit again, objectively not so good, 2...e5!? but of practical value,
first played at high level by Indian GM Das when he was 13, then already 2400 Elo
https://en.wikipedia.org/wiki/Debashis_Das
Ironically he lost that game when his opponent with White did not accept the gambit but simply
proceeded with 3.Bg2

and another Black gambit, starting with the rather unconventional 1...Nc6 (after 1.e4) the Nimzovich
defense, with which i recently get quite decent results (also myself with online play, btw).
Then with ...f5!? we get the Nimzovich Colorado gambit, played in 2023 in blitz by nobody
else than a certain Carlsen, the great where he easily won against a 2600 player.

here's the game (with the 'f' key you can flip/reverse the board)

Here a positive story about this gambit.

although objectively speaking it's not so good eg according to this (imo exaggerated) article
https://chessmood.com/blog/complete-gui ... ado-gambit
Not good ? well, maybe not in slow games, i would suggest. But in blitz, people (or average engines)
make mistakes; like Rodin in the above game with the move 19.f5...

[jefk]

game nr 19 with a Black win again. Not a gambit this time, but nevertheless an aggressive defensive
('opening') move for Black with 3...f5! played earlier in blitz by the young Dutch GM Jorden van Foreest.
And this time against a club level player, a weakened Ufim (so not for theoretical purposes, but showing a
strong human player can have fun with such 'aggressive' moves rather than the (boring?) main lines.

apparently i reached now 1000 postings on talkchess; a sign of a 'wasted life' (quoting Morphy) ?
Well depends, actually i'm demonstrating a new paradigm in the game of chess, abandoning main lines
and carefully selecting gambits again, in the style of centuries ago, but this time much more accurately(*),
and also with faster time controls. Meanwhile also updating the gambit book, and once i reached
100 of such games here, i may select the top 50 or so and then offer them to New in Chess or similar
for publication (with advance fee of > 30 k of course whereby they can do the final editing).

(*) actually i wouldn't hesitate to play an RvD gambit (depending on Black's second move) or otherwise
a Sicilian wing gambit after 2...e6 even in correspondence chess

The Dragon defense in the Sicilian has been analyzed in detail, also in recent book(s) eg but Dutch GM Anish Giri
https://www.debestezet.nl/catalog/produ ... ts_id=5497
With best play White should be able to achieve a slight advantage. But then as human you need a memory like from
Magnus C or as engine an impeccable opening book. In this game Black was able to outplay Rodin with it's basic
book and the Rebel extreme engine with my 'gambit' (sharp) book. The kings attack at the end was illustrative.

and one more for Black, a Benko gambit again, and a novelty at the 11th move for Black

game nr 22
A White gambit again, this time 'only' two pawns sacrifice but an interesting novelty 7.Bf4!
and thereafter an interesting game with an instructive attack by White.

After 4...Nf6 5.Nxd4 we would get a transposition to the awesome Ginsburg gambit (...Nxe4) with sharp play

Apparently invented by IM Mark Ginsburg
https://nezhmet.wordpress.com/about/

In my gambit book there is 50 pct chance for 4.c3 (Smith Morra gambit) and 50 pct for this 4.Bc4
The Black move 5...e5 trying to preserve the pawn on d4 is not good because of 6.c3!
As e.g. already played by a certain Baron Tassilo von Heydebrand under der Lasa in 1847
https://en.wikipedia.org/wiki/Tassilo_v ... d_der_Lasa
against a certain Wilhelm Hanstein https://en.wikipedia.org/wiki/Wilhelm_Hanstein

nr 23,
another Sicilian wing gambit (not an Rvd gambit because a3 isn't played);
after 2...d6 you also can play 3.d4 and after 3...cxd4 go for the Smith Morra,
but the wing gambit also is playable (personally i prefer it after 3...e6)

nr 24
with a regular/rare opening; traditionally, it is thought that White should aim for center
dominance, either directly or with a fianchetto (of a bishop in the corner);
In this opening, which also can arise from the Anderssen opening (1.a3)
the fianchetto is delayed.

which tool(s) ?

One that satisfies my needs , wrote it myself in the meantime.

well Ed, by far most of the annotation(s) were done with Fritz19; full analysis with comments, 2 or 3 s per move.

Fritz analysis is very nice, but it can only do one game at the time, not a whole bunch.

To see if it's an interesting game, i usually first look with Chessbase 18 (report, novelty seeker);
which goes quite fast nowadays, and besides the novelty it then also list the predecessor game.
Sometimes i throw in some extra ! or so, or a small additional comment (eg at a critical moment)

Very nice games you posted, is it possible you put all of them in a PGN for download?
