Big Collection of Chessity.com puzzles (2000+ Puzzles so far WITH SOLUTIONS )


These puzzles were obtained from the tactics site chessity.com, please go to the site and take a look around and get a feel for the puzzles. We believe these puzzles have a high educational value and they were hand made/hand picked by a master chess trainer and that's why we would like to share them with you. Again, please see the website for more details.

If it's white turn to move, then the puzzle will say 1-0, and if it's black's turn to move, it will be 0-1.There are all kinds of puzzles: tactics, all sorts of defensive puzzles, checkmates, quiet moves, and the puzzles range from very easy to very challenging. I think they provide a good range of difficulty and most importantly they seem to be very practical in nature.

Specials Thanks for the team in immortalchess.net for collecting theses precious gems.

Detecting Fortresses in Chess, Matej Guid, Ivan Bratko

Detecting Fortresses in Chess
Matej Guid, Ivan Bratko
Artificial Intelligence Laboratory, Faculty of Computer and Information Science, University of Ljubljana
Abstract.
We introduce a computational method for semi-automatical detecting fortresses in the game of chess.
It is based on computer heuristic search and can be easily used with any state-of-the-art chess program. We
also demonstrate a method for avoiding fortresses and show how to find a break-through plan when one exists.
Although the paper is not concerned with the question whether it is practical or not to implement the method
within
the state-of-the-art chess programs, the method can be useful, for example, in correspondence chess or
in composing chess studies, where a human-computer interaction is of great importance, and the time available
is significantly longer than in ordinary chess competitions

Don Dailey, author of the Komodo chess engine, passes away 1956 -2013

Here is a nice piece written about him by the co-author of Komodo Grandmaster Larry Kaufman
Don Dailey, my partner in chess programs from RexChess to Komodo spanning a quarter of a century, died tonite in Roanoke Virginia at age 57 from Leukemia, just about the same time that Komodo pulled ahead of Stockfish by winning game 2 in the TCEC final. He no longer even recognized his own family on the final day, so he could not know about this, but was still somewhat lucid the day before so he did understand that Komodo had made it to the final. He is survived by his wife Mary, one brother, and both of his parents. He was raised as a Jehovah's Witness and served in recent years as an "elder" in the church.
Don's life story is rather amazing. He grew up in relative poverty in Michigan, and never even graduated from high school (though he later got a General Education Diploma via a test). He taught himself how to program computers as well as how to play chess (his best rating was in Class A, somewhere around 1900 I believe). Despite the lack of formal education, by the mid 1990s he was the head of the computing department at M.I.T. (!!!!). Probably they never imagined he had so little formal education. It is a curious coincidence that Don had this job, that I was an M.I.T. graduate, and that Vasik Rajlich whom I worked with on Rybka 3 was also an M.I.T. graduate. It is likely that Vasik and Don interacted at the computer dept. there, although neither remembered knowing the other back then.
I first met Don in the late 1980s. He had written his own chess program and competed with it, although it was not yet very strong. His chess advisor was the notorious Sam Sloan who happened to be living in the Roanoke are where Don had settled. That didn't last too long, not surprising considering Don's strong ethics and Sloan's reputation. When Sam had to flee the country to avoid prosecution he introduced Don to me, and I took over as the chess advisor. Soon I persuaded Don to move to Florida where I then lived to devote himself full time to computer chess, and we developed Rexchess, Socrates, and (with Julio Kaplan) Kasparov's Gambit. Then Don took the M.I.T. job and moved to Boston, later moving on to a position with a tech startup. He told me that the stock they gave him was on paper worth five million dollars at one time, but he couldn't yet sell it and the 2001 tech crash nearly wiped out his equity. About that time he married Mary and they moved back to his favorite Roanoke, a major center for Jehovah's Witnesses. He made a living doing a variety of programming jobs for most of that decade. Then we got in touch again, Don expressed an interest in writing a new chess program, and I agreed to help him although at the time I was still working on Rybka, Vasik having no objection. Neither of us imagined that it would become a threat to Rybka's primacy, but events showed otherwise. After my Rybka work concluded we decided to aim for a commercial product. After a while I agreed to subsidize Don so he could devote full time to Komodo until it went on sale. But about the same time he learned that he had a terminal illness which would become a fatal Leukemia after a few years. He never really made a living from Komodo until the final months of his life, but was able to get by due to very low cost of living in Roanoke, some savings from the tech days, and his wife having a job. He certainly could have made far more money doing business programming, but he wanted to do what he loved more than he wanted material possessions.
At least Don lived to see Komodo surpass Houdini in every stage of TCEC, although whether Komodo or Stockfish is the new number one is yet to be determined. During the last weeks of his life, following TCEC was a prime interest for him.
I'll post more information as it becomes available.
Good Bye Don, Mark and I will do our best to see that your brainchild Komodo continues to improve and give chessplayers around the world much joy.

The White Chess Collection



The White Chess Collection- John Griswold White (1845–1928) was a prominent Cleveland attorney, a chess connoisseur, and a bibliophile.[1] "Over a period of some fifty years he conducted a determined quest, throughout the world, for desirable additions to his library."[1] Chess historian H.J.R. Murray, who called White's chess library the largest in the world,[2] made extensive use of the collection in writing his classic treatise A History of Chess.[3] White donated his collection to the Cleveland Public Library to form the John G. White Collection on Folklore, Orientalia, and Chess.[1]

The library has since split the collection into three. The John G. White Chess and Checkers Collection is described as the "[l]argest chess library in the world (32,568 volumes of books and serials, including 6,359 volumes of bound periodicals.)" The John G. White Folklore Collection contains 47,040 volumes, "one of the largest in the nation. It is broadly defined in scope and international in coverage without period restrictions. Included are primitive, peasant, native, and folk cultures within geographic restrictions." The John G. White Collection of Orientalia includes "materials on Asia, the Near and Middle East, Africa, Australia and Oceania," emphasizing "the humanistic and social science aspects of traditional cultures prior to the impact of European influence."[4]...

Masters of our time : Impatience and Self-Control in High Level Games on gender differences

Here is an odd one ... Swedish Institute for Social Research ... MASTERS OF OUR TIME: IMPATIENCE AND SELF-CONTROL IN HIGH-LEVEL CHESS GAMES

PATRIK GRÄNSMARK
Abstract
This paper presents empirical findings on gender differences in time preference and inconsistency based on international, high-level chess panel data with a large number of observations, including a control for ability. Due to the time constraint in chess, it is possible to study performance and choices related to time preferences.
The results suggest that men play shorter games on average and pay a higher price to end the game sooner. They also perform worse in shorter game compared to women but better in longer games. Furthermore,
women perform worse in time pressure (the 40th move time control).
The results are consistent with the interpretation that men are more impatient (with a lower discount factor)
but also more inconsistent in the sense that they tend to be too impatient.
Women, on the other hand, are more inconsistent as they tend to over-consume reflection tim e in the beginning, leading to time pressure later....

The Bishop's Opening and The Urusov Gambit System by Michael Goeller

Welcome to The Urusov Gambit System, a constellation of web sites devoted to the Urusov Gambit (1.e4 e5 2.Bc4 Nf6 3.d4 exd4 4.Nf3) and all related lines. Follow the links below (or in the navigation bar at the top of the page) to explore some fun analysis, games, and chess history. And be sure to check out the extensive links to other web sites. 
1-The Bishop's Opening covers 1.e4 e5 2.Bc4 with all Black alternatives to 2....Nf6. The focus is on exciting gambit lines, so don't expect to find anything pianisimo here. The idea is to help you play against people afraid to enter the Urusov zone.
2-The Urusov Gambit covers play after 1.e4 e5 2.Bc4 Nf6 3.d4 with attention to 3....exd4 4.Nf3, the Urusov Gambit proper. This is the most extensive analysis of the Urusov available anywhere in print, with a great collection of games. If you like to play the Urusov Gambit, you've come to the right place. 
The little-known 3-Dimock Theme Tournament of 1924 featured such famous American players as Marshall, Torre, and Santasiere contesting lines stemming from 1.e4 e5 2.Bc4 Nf6 3.d4. A great piece of chess history and theory. Play over the games from this "lost" event right on the web.
4-The Perreux Variation of the Two Knights Defense (arising after 4.Nf3 Nc6 5.Ng5) is one of the most forcing and least covered lines in the Two Knights, featuring exciting play with chances for both sides. This site also includes links to analysis and games in other lines of the Two Knights Defense.

The Life and Times of Mikhail Tal Last Days of Tal



A genial genius at work – Tal blindfold simul in video

A genial genius at work – Tal blindfold simul in video

The wonder that is YouTube occasionally throws up something really fascinating. We have a great example – a ten-minute video that shows a blindfold simultaneous display, given by the immortal Mikhail Tal. The date is unclear and the commentary is all in Russian, but we have prepared a summary transcript in English. We were even able to reconstruct four game fragments. Must watch.
 

A genial genius at work

The following video was pointed out to us by Mark Hanon, Oxford, England, and was studied by our Russian-speaking associate Steve Giddins, who prepared the following synopsis.
Addendum: Valery Adzhiev of Bournemouth, UK, informs us that the video is a fragment from the documentary "Seven steps beyond the horizon" about the limits of brainpower (director: Felix Sobolev). It was made in 1968 and released in 1969.

The commentary is all in Russian and unfortunately, does not reveal the date of the performance. Initially, one sees the announcer going from board to board, announcing the board number and the move played. Tal usually replies almost immediately, but at one point, he replies "Just a moment", and thinks for a minute or so, before moving. The commentary then clicks, in, with an interviewer posing questions, and Tal replying. He is asked whether he has been doing such blindfold displays very long, and Tal replies that this is his first such display. "Well, actually, not strictly the first," he then adds. He explains that he once gave one whilst in hospital, recovering from an operation! It seems that in this display he won three games, and would probably have lost the fourth, had his opponent not been taken off to the operating theatre at the crucial moment! The present display, though, is Tal's first public exhibition of blindfold simultaneous play.
Tal mentions that Alekhine gave such a simul over 30 boards, and that "there is also in Hungary a young master called Janos Flesch, who has done  a simul on 54 boards". Tal admits that he cannot imagine doing a display over such a number. When asked how he can play such blindfold games, and whether he sees the pieces exactly in his mind, he replies in the negative, and adds that it is impossible to explain how one's mind works in such situations.

Sadly, one cannot see the boards, nor are the full scores of any of the games given. However, at a certain point in the display, Tal recounts the moves so far, of four of the most interesting games. This section occurs between 3.55 and 6.40 minutes, and even those who do not speak Russian will get some impression of how fast Tal is able to recite the moves, purely from memory. These are the fragments of the four games:
Tal - N:N [D06] Board six
1.d4 d5 2.c4 Nf6 3.cxd5 Nxd5 4.Nf3 Bg4 5.Qb3 Nb6 6.Nbd2 e6 7.g3 Nc6 8.Bg2 Be7 9.0-0 0-0 10.Rd1 Nxd4 "A perfectly correct decision" 11.Nxd4 Qxd4 12.Bxb7 Bxe2 13.Re1 Rab8 "This move I had failed to notice in advance". 14.Bg2 Ba6 "Here, I thought 14...Nd5 or 14...Nc4 were more dangerous". 15.Nf3 Qb4 16.Bf4 Nd5 17.Bd2 Qb6 18.Qxb6 cxb6 19.Ne5

Tal - N.N. [C54] Board seven
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.c3 Nf6 5.d4 exd4 6.cxd4 Bb4+ 7.Bd2 Bxd2+ 8.Nbxd2 d5 9.exd5 Nxd5 10.Qb3 Be6 "This move I have never come across before, but it seems to me to be very interesting". 11.Qxb7 Na5 12.Bb5+ Kf8 13.Qa6 c6 14.Ba4 Nf4 "A very interesting move!" 15.0-0-0 "Unfortunately 15.0-0?? is not possible because of 15...Bc8"

Tal - N.N. [E91] Board eight
1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 0–0 6.Be2 Nbd7 "Here I sacrificed a pawn". 7.e5 dxe5 8.dxe5 Ng4 9.e6 fxe6 10.0–0 Nde5 11.Qc2 Nxf3+ 12.Bxf3 Ne5 13.Be2 Qe8 14.Be3 Nc6 15.Rad1

Tal - N.N [C93] Board nine
1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0–0 b5 6.Bb3 Be7 7.d4 d6 8.c3 0–0 9.h3 h6 10.Re1 Re8 11.Nbd2 Bf8 12.Nf1 Bd7 13.Ng3 Na5 14.Bc2 g6 15.b3 c5 16.d5 Nb7 17.Be3 Bg7 18.Qd2

Shortly afterwards, we see the opponent on board eight offer a draw. Tal takes a long puff of his cigarette, announces "I will think about it", and then thinks for a minute or so, before announcing his wish to play on, and indicating his move. At 7.26, Tal is informed that his opponent on board three has played Ke8-f8. Immediately, he replies "I think Black has made a mistake. I can play b4xc5. Maybe Black would like to choose another move instead?" His grateful young adversary takes his advice!

In the final few minutes, we see various games ending. On board 10, Tal is offered a draw, and accepts, adding with a smile "I thank my opponent for his generosity. He helped me to save this game". Board seven also offers a draw, which is accepted. Board three resigns, and then Tal offers a draw on board six, which is accepted. The announcer declares the final result of the display: 7:3 in favour of the grandmaster, with four wins and six draws.

In conclusion, declares the narrator, the display is a remarkable demonstration of the potentialities of the human mind. As a chess fan, I can only add that the video itself is a delight, a unique chance to see one of the great figures of chess history demonstrating his remarkable talent. If any readers out there know where any of the game scores from this simultaneous can be found, we should be most interested from hear from them.
