You have little chance in your dissertation of surpassing state of the art chess engines. Perhaps you could find a hook which hasn't been explored so much. One idea is to train your program to play amateur chess in a convincing way. Can a program pass a sort of chess Turing Test where a human-player couldn't tell if they were playing an AI or playing a ...

This calls for some scripting, so here's my first hasty attempt at it ;) Here's a quick way you can do the search on your own in python, using stockfish 10 and only the python-chess package. All open-source and free-software! Briefly, what the script will do: Consider all 960 positions, one at a time For each position, it scans over all legal white moves ...

There is no hurry. After 8. Bb2 the bishop on b6 is not going anywhere. NxB continues to be available to white until black does something about it like a6. That means that delaying NxB gains a tempo if black has to make a less useful move to try and "save" the bishop like a6. Since recapturing with the a pawn probably gives black a better game it is worth ...

It is a fairly short and simple explanation: They can combine to attack any square, not just squares on one color. As part of that they can also shift the attack better from one square to another.

Because that was the move that the computer saw lost the least material. The BEST you can do there is just get two minor pieces for the queen. It gets worse after Qa4. Even just Nxc7 wins so much material that it is easy, but there is even better. [FEN ""] 1. e4 d5 2. exd5 Qxd5 3. Nc3 Qa5 4. Bc4 Nf6 5. d3 Bg4 6. f3 Bf5 7. Bd2 e6 8. Nge2 Nc6 9. Nd5 Qa4 10....

In the diagrammed position you have a material advantage but Black's position is a little bit better because his rooks are connected and he has a safer king position. His immediate threat is RxR, when you have to retake with the king followed by Qg1+ and after you move Kd2 he will play Bb6 and the pressure around your king will become intense. You are paying ...

One of the problems with chess-analysis software for weaker players is that it just shows the strongest move per the computer, without any explanation why. There are some programs, like the ChessBase programs that, using their "Tactical Analysis" feature, attempt to give some explanation to the moves, but they are all wanting. That said, decodechess.com ...

This is a very famous position. Well, here are some reasons, and there are quite a few: Since this was a Candidate’s Match to qualify to play Spassky, it comes down to exact calculation above all. Fischer calculated that it was good, and his judgement bore out since the game only lasted another 12 moves. Here are some things that probably contributed to ...

White intends to play c5, which will gain space on the queenside and severely cramp black's position (The b6 knight has no good square). On the other hand, e5 weakens white's control over d5 and f5 (e.g. Black can then go ...Ne7-f5). Black could also take advantage of the weak c4 and d5 squares with ...Na5 and ...Bc6. Keeping the pawn on e4 seems better. ...


17

There is no king on the kingside yet to attack. Black might very well castle long in which case your attack is aimed at nothing and might potentially weaken your own king's safety. 5....c4 is premature and unnecessary. It loses the pressure on the d4 pawn and loses a tempo for development. A very typical reply to such pawn structure is b3, which is based ...


17

Short answer: Since after the bishop recapture on f8 (and not the rook recapture!) white is tactically and positionally completely busted, with 5 active black pieces against a completely exposed king in the centre and no foreseeable chance of consolidation in order to eventually benefit from the material advantage. First observations: 15...Bxf8 is with ...

You might be interested in AlphaZero and its derivatives. AlphaZero is the original neural-network based chess engine; since then there have been various other attempts (Leela Chess Zero, AllieStein, the recent Fat Fritz ...) to replicate AlphaZero's ideas. The key paper to read is this one. The data right now seems to indicate that although these neural ...

One of the ways I teach kids how knights move is to put the queen and the knight on the same square. The knight can go to the nearest squares that the queen can't go to. It is this unique complimentary nature of the two pieces which means that they form such a potent combination. With queen plus any other piece this is missing and there is a duplication of ...

John Watson's "Secrets of Modern Chess Strategy" contains a section titled "Folklore or Reality? Queens and Knights" John lists some folks that say Queen and Knight are better Capablanca Shirov Silman And refers to Steve Meyer's book "Bishop vs Knights" which also says the Queen + Knight is better. I am currently playing through "Karpov move by move" ...

Using @Phonon's Python script, I was able to determine that the worst move is 1. g4?? from the BBQRNNKR starting configuration, or 1. b4?? from its mirror image. This evaluates to -2.5 in one second of Stockfish search. Not quite a minor piece, but still a substantial handicap to recover from. Why is this position so powerful for the opponent? The black ...

Brian Towers' answer is excellent. I'll just add this: if you play Rxe8, you are effectively trading your e1-rook for your opponent's a8-rook. A glance at the position should show that your e1-rook is a lot more valuable than your opponent's a8-rook. It is currently already developed and participating in the game, while the a8-rook (like your a1-rook) is ...

First, the good: You are probably winning this throughout the game, and thus, improving your position gradually was the perfect plan. It also was one of the best examples of Shereshevsky's "Do Not Hurry" principle that I have ever seen. Black could do nothing, so gradually improving, and eventually converting, was perfect since you had all the time in the ...

It's not that unpopular amongst off-beat lines that can emerge from the Sicilian defense, on top which it has a natural tendency to transpose to Owen defense type of positions. As to why it's not as popular as Sicilian mainlines, much similar to 1.b3 or 1...b6 openings, 1...c5 2...b6 is not a sound starting setup strategically, for the following summarised ...

I had an extra pawn and was closer to my pawns then White It seems you simply overestimated these two factors. An extra pawn alone is not a decisive advantage, it matters a lot where it is located. If the f7 pawn was on a7, you'd win. The kings are actually positioned to your disadvantage, White's is nicely centralized and yours is stuck in the corner. ...


11

To be frank, I was a little surprised that this was a draw per the computer from move one all the way through to your stalemate. You did not make a mistake. My initial thought was to play the black king to g8-f8-e7, but the problem is that white can keep the K out of e7 with his own king, or keep you on the back rank, or force you to make pawn moves that are ...

Can black play for a win? Heck yes! This is totally won for black. I did not even realize you were up a pawn at first, and I was thinking there is a clear plan here. First, here is the analysis of the position. You are up a pawn. You have the better minor piece. White is weakened on the queen-side since black can put a piece on c4, and b3 is just horrible ...

Short of asking a deceased man, I would say that the answer is "no way". He won the 5th World Correspondence Chess Championship in 1965. Computer chess, if it existed at all, was not strong at all. Even with mainframe-type hardware back then, it paled on comparison to the first Chess Challengers of the early 1980's, and they were only rated about 1200 then. ...

First, by far the most popular chess YouTuber is Agadmator. His channel does a nice job of going over famous games, and explaining them. Other good videos are what are called "banter blitz". Banter blitz is when players, and you want to watch Masters, explain what they are thinking aloud as they are playing. You can then get a better idea of what we see, ...

You do not have enough control of e4, and if white gets to play e4-e5 here, your king is a goner. It is an absolute must here to stop that plan, and the only way to do it is d5. Making your Bb7 bad for now pales in comparison to letting your king get mated, or loss of significant material, which will happen after e4-e5.


11

Note: This is an analysis of the position at move 34. Obviously, White's play in the beginning of the endgame was poor and he should never have entered such trouble. Black's advantage is clear and long-lived because he has the better minor piece, a knight vs a bad bishop with a locked center. Whether this advantage is enough for a win requires analysis, of ...

There are plenty of possible Phd-topics that connect chess and machine learning. The more interesing and feasible ones have nothing to do with building better engines. Here are some ideas: Human players have a particular playing style. Is it possible to learn to extract some metric of style from games that allows to assign games to players with a certain ...

Looking at the engine output, it seems that after Black plays cxb4, White can play a3. If Black takes, this opens up the b-file, and if White is allowed to play axb4, that opens the a-file. Either way, lines towards the Black king will open up.


10

These players are just pretty weak. 5...Bg4 should already have been punished by Bxf7, many more blunders follow. Qg6 is a double attack against c2 and g2, that's probably motivation enough.

I have been looking at this with a fairly strong computer for about 15 minutes (and the judgment of having been a Master for 30+ years and forcing in plausible lines), and I am convinced that this is a positional draw. White is obviously worse per the computer eval, but he can keep the position exactly as it is by either moving his K from e2 to d3 and back (...

What a beautiful domination of black's king by the knight and pawn setup on c5,e5, white is essentially up a king in this endgame! Given that black is completely unable to create any threats, you have all the tempi to centralize your king and aim for a specific setup thereafter. One potentially simpler plan that springs to mind is, targeting black's weak ...
