[PART 2] I made program to find craziest sacrifices in a row.

Appetiser

Important information

Please take note that people weren't able to subscribe to me, since I had that disabled. Fixed now*
Positions that are included in this article were found by my own program, in games played by me, and 10k bullet games that were played by Magnus Carlsen. Take note that all those moves are the missed ones, meaning we didn't actually play those brilliant moves, so even if you somehow saw all bullet games played by Magnus, all those sacrifices still remain 100% unique to you, and I guarantee that you haven't seen those patterns ever before!

General words

Greetings, chess players! I hope you are enjoying the last month of your summer. Welcome to the second article about my program that finds brilliant sequences! If you haven't seen my first article, make sure to check it out! It has another 30 brilliant sacrifices, which are all different from these ones.

When I first published it, I didn't think it would get much attention. In around 10 days it got 300 views, and I was pretty happy with it! However everything changed when one of the lichess devs or an automatic system for some reason decided to put my article on the main page. When I woke up, I couldn't believe my eyes, people started watching it, and more importantly liking it! As of now it has a lot more views, a month has passed since then, and a lot has changed in my program. For example, it is now around 30 times faster, and that means that I can create those articles on a weekly basis. However, I decided that it is not a good idea, and it is better to improve the quality of the positions that I will share instead. Another change is that now it seeks brilliancies in the top 3 lines of the engine, which may lead to finding more !! in games. I also decided to analyse around 10000 Magnus Carlsen's bullet chess games played on lichess, to find brilliancies that he found and missed, since all my games were already analysed. Some of the positions here would be from games played by me, my friends, and the 16th world chess champion himself. However, most of those brilliancies are missed ones, so it really doesn't matter how strong are the people whose games are analysed. It could even be a 1000-rated player, the amount of missed brlliant moves won't be lower.

How to get the program?

I've spent quite some time working on the application that makes it easy to analyse your own games, pretty much copying everything I could from a famous chess website. It pretty much has the exact game review (besides textual annotations), has exact graph, brilliant move finder, fork/pin/skewer/hanging piece identifier. It also has insights, to see all your brilliant moves that could be sorted in all possible ways, also all your missed and found forks, pins and pretty much every stat you can see. However, I can't publish it right now, due to one main reason - since it uses some images that don't belong to me, I might have some problems. That doesn't mean that I would never upload it, however it takes time to solve those problems and find a good decision.

Plans for the future

I actually have an amazing idea for the next article. I could analyse all the games played by Leela odds bots, there are more than million, and since we can assume they are perfect, there is no need to even start an engine. The whole process wouldn't be that slow, but it will require some serious changes in my program and a lot of time to sort out good ones. One of the changes would be to the brilliant move formula. Right now, the move that sacrifices a piece in a totally lost positions, which according to stockfish, the bot always has, couldn't be brilliant, because it is losing anyway. That has to be changed, and it will take quite a lot of time. Ideally, I will make this program available for everyone, so they can see all statistics in their games, and they send me one file which contains all the positions with 2 brilliant moves in a row as a part of mutual deal. However it's safe to say, there is a lot of time to come before I would release the program anyways.

Brilliant sacrifices

As usual, my program has found way too many brilliant moves (around 10.000). So to get the best out of it, I decided to sort out only the ones in which the move after the capture of sacrificed piece was also a brilliant sacrifice. Most of the positions here are 2 brilliant sacrifices in a row, but some even include 3 of them. We would be going from worse to better, so the positions are gonna be more and more brilliant!

Interesting way to win a queen

I didn't really want to include the positions that end up winning material, since they aren't truly brilliant. However, I decided to include few of them, just to heat things up!

Another way to win a queen

Wherever white moves the queen, black will have a strong retreat

Alright, now only true brilliants! Who doesn't like sacrificing pieces for the checkmate?

And Rh8# is unstoppable

That's why you shoudn't keep your king in the centre

We play b5, so the bishop cannot go to f1 anymore, preventing the mate on g2 square

Black has no way to defend against threats to their king and pawn promotion

Ordinary 2-rook sacrifice for checkmate. Things are about to get more beautiful from now

Somehow engine always finds creative ways to convert space advantage

Creative way to start an attack!

Everything to open up the "g" file.

This is both an attraction and distraction sacrifice. How often do you see those in a row?

Both rooks sacrificed on the same square!

This is why engines never play passive openings

This is why you shouldn't put your pieces far from defending the king

And that's why the king is bad in the centre. Those sacrifices are actually a good way to learn concepts!

R1e4 is such a brilliant move, not only because it is the only move not to get checkmated, but also because it prepares another sacrifice, which would let us checkmate our opponent! Isn't that what you call "Uno reverse" move?

This is so brilliant, we sacrifice an exchange, so that only one piece protects the g5 square, so we can sacrifice another piece on that square. Think about it, isn't chess a fascinating game?

Be honest, you didn't expect this one, right?

How about that one? I bet you all will overprotect your king after this!

Isn't it fascinating, with how much ease does stockfish remove defenders?

Take a note that if Black don't capture the bishop, and for example play Bc6, that leads to a Nxe6 fork.

Advanced pawns also don't scare stockfish!

Those are starting to get crazy! If you had enough patience to scroll through the worst ones, you will be rewarded

The heat is rising, and the board is burning! That burns all myths of "safe fianchetto", Black cannot stop both mate threats at once!

This straight up looks like alien chess, we were already down 2 pieces, and we are giving away 2 rooks, to end up in perfect checkmate while down 12 points of material!

From now we are getting to the cosmic level of brilliance, make sure your space suit is ready, because you don't want to miss this trip!

Come on, what are we even looking at? Two knights sacrificed on neighboring squares to perform checkmate in 5!

Those positions are so aesthetically beautiful to me, that once again proves that chess is art

I don't think seeing chess positions has ever been so entertaining for me, if you have made it this far, perhaps you wanna share some feedback in the comment section?

The level of harmony is way too high!

This is getting out of hand. I don't even have enough words to describe it...

Now we are getting to the positions with 3 sacrifices in a row. Should I even mention that we are sacrificing a rook, a knight and a queen?

We are ending on a beautiful note of what's called "perfect checkmate", which is when all pieces participate in it.

[Bonus] I decided to make a separate category just for the Greek gifts, because there was quite a number of positions that had 2 sacrifices in a row in this checkmating pattern.

That's not quite the Greek gift, the bishop thought they were the knight!

That is gonna conclude the article, I tried to make it entertaining, and I hope you will like it as much as the previous one.
If some of you have read the first article - I would like to receive some comments whether it is equally good, worse, or better than the first one. This information might help me in the future. Feel comfortable to criticise me, share your own brilliancies, ideas, or ask any kind of questions. I will try to respond to every question asked.
Have a great rest of your summer, dear chess players!
