there is chess puzzle of the day which is amazing

and I thought perhaps there could be chess tactics and strategies of the week which could be informative

Chess Tactics and Strategies of the Week could be made by anyone I guess
so if there is somebody who has a good tactic to show
anyone can write I guess
cuz I think if there are more ppl who are writing about some things
the better

(by the way,
it is like the following thought
if there is one person who is running a tourney
it is not easy to run 1000 matches
but 10 ppl just run 100 rounds
and we combine the results
then we can get 1000 matches very quickly (from 10 ppl's collaboration)

so I guess anyone can write about the tactics and strategies)

it is like the cloud
and I'm not 100% sure but even stockfish testing framework is based on the cloud perhaps
it is not easy to have one very powerful supercomputer
so there are many computers which are interconnected and correlated with each other on the net via cloud concept


so if there are 100 computers with 8 cores which are connected thru cloud
it is like they have "one" giant supercomputer
with 800 cores working in tendum with others
and that's something!


***


so I'll do this "Chess Tactics and Strategies of the Week"

I can write as many as 10 posts a week I guess
or as little as a few posts a week I think

but here is the thing

I'll not write about a tactic or a strategy
which I read or saw from a book or something like those published materials
for chess learners and chess students
that were made by other ppl

I'll post tactics and strategies that are made by me running a tourney
so I'll watch a plethora of multifarious engine Vs. engine matches

and if I find a really good match (tactically and strategically)
between engines
then I'll post the pgn of the match
along with some key points!


***


the following is one example of such method




Chess Tactics and Strategies of the Week Asdfqw11



the detailed explanation:
https://www.chess2u.com/t7683-amazing-rare-match-rare-showing-of-resilience-by-stockfish


so if I find a really amazing match between engines
like the above aforementioned illustration
I can post the pgn with some diagrams
and comments!

thinker 5.4D is a powerful engine with elo of 2950
I think 3250 Vs. 2950 matches can produce very good tactics and strategies

the elo gap of 300 or so is very suitable after watching many matches
between thinker and SF

so thinker is suitable to produce unlimited number of
high quality tactics and strategies


thinker is very special
it has the size of only 70 KB
when other big-sized engines are up to several MB

thinker is light weight and
only 70KB engine can be 2950 elo strong!
and that's unbelievable

when we look at the first post in this thread
there was a very good match
about locking down opponent's 2 rooks


I thought that match was done by SF
but it was done by houdini
I found the match pgn
that match was specially amazing and good
so I saved it in my storage folder
and I could find it after some searching


that match is like the nominee for the best match of the year
in my opinion
