This answer spells out the actual calculation of performance rating for USCF tournaments, as in the June 2017 Rating Estimator that Fred Knight's answer points to. If you view the page source at that ...

I can't find the actual game neither in my database nor at, say, chessgames.com. However, the position appears as puzzle 210 -- with the apt description "Running around like a squirrel in a cage&...

Yes, it seems to be drawn. First consider the following variation, but in particular the position after 2.Kxh5 first: [FEN "8/8/8/3k3p/3P3K/2P3R1/8/7r w - - 0 1"] 1.Rh3 Rg1 2.Kxh5 Rg8 3.Rf3 Kc4 4....

I believe black can do no better than a draw from the starting position. First I'll give my own reasoning for it (and everything I'll say I've checked with Houdini, to rule out silly oversights on my ...

In one sense, I would simply say, "Yes, the pawn structure would be the first indicator that one has entered/transposed into a given opening." But since there's no other answer here as of yet, I'm ...

I highly recommend Scid ("Shane's Chess Information Database"). Here's a screenshot of the Mac version (more to be found at Softpedia): It is completely free, has lots of functionality, and is fast (...

White to play and mate in 4, while forcing the black king to capture on each move: [fen "1r2qrnk/3R1bRp/pp2nBpp/p3P3/4B3/5PPQ/PPP3N1/1K6 w - - 0 1"] Solution:

Different engines have different "scales" for their numerical evaluations. For instance, in a typical middlegame position with plenty of play left, when Houdini says +2.00 or better, it is highly ...

Looking at some results drawn from 2,000,000+ games, we have these winning percentages for the two openings: White Draw Black ----- ---- ----- Bird's 34 25 41 Dutch 42 30 ...

"Tactics is knowing what to do when there is something to do. Strategy is knowing what to do when there is nothing to do." -- Savielly Tartakower What follow are the most salient features of the ...

This may or may not be your cup of tea, but if you are a LaTeX user, then SCID's LaTeX export feature produces ready-to-compile LaTeX source that yields rather nice (IMO) PDFs quickly and painlessly. ...

Considerations such as yours for a definition of "space" have long been a part of computer chess, and I suggest looking to that literature for ways to approach a precise, quantitative definition. The ...

It's worth revisiting this question in light of the recent striking success of AlphaZero against Stockfish 8. A further evolution of DeepMind's AlphaGo and AlphaGo Zero programs, AlphaZero finished ...

If you have a collection of games in PGN format, you could probably search for threefold repetitions using the Chess Query Language. In particular, you might look in the "Matching positions: the ...

Million Base 2.5 (available from a link here) and ICOfY Base are two free options that more than meet your given criteria, each providing millions of games in PGN format to draw from as you please. In ...

I don't know the game you have in mind, but the following is one example of such a drawn position in this ending (as can be verified with a tablebase query): [fen "8/8/1r4kP/6P1/2R2K2/8/8/8 w - - 0 1"...

It is not so much that Fischer got exiled as much as it was that he chose to exile himself (though yes, out of a certain necessity). He was indicted by a U.S. court for ignoring sanctions against ...

Chess Position Trainer recognizes transpositions in exactly the way that you're after, as it stores its opening books in a way that's designed to address this issue. Whenever two variations (like your ...

Because of the observation you make, that the tree of possible game paths for chess is finite, chess is indeed solvable in exactly the same sense that tic-tac-toe is. So optimal strategies for chess ...

The following passage is from Botvinnik's foreword to his 100 Selected Games. The text here doesn't single out one's own games as the specific object of analysis, but it leaves no doubt about ...

Analysis of this general endgame appears in Staunton's Handbook, in the section "King and Three Passed Pawns against King and Three Passed Pawns." In the preceding section of the book, "King against ...

Here's another example each of a rook promotion and a bishop promotion from actual play. Neither specific promotion was quite absolutely necessary (you'll see what I mean), but neither one was at all ...

Compare the position after 3...Bc5 to that after 4.b4 Bxb4 5.c3 Bc5 6.d4. [fen ""] 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4 Bxb4 5.c3 Bc5 6.d4` It's true that the Black bishop has simply returned to c5 and ...

I suppose you have some source that claims 1.g4 is the best move from the diagram position, but which doesn't give any reason for it. I won't try to weigh in on whether it is in fact the best move ...

Black is winning handily from the diagram position, and has a fairly straightforward strategy going forward: force the b-pawn's advance to b2 with the support of the bishops (starting with 1...Be6 to ...

I believe that GloriaVictis' answer addresses your first position very well, in that the pawn is not actually securely blockaded in that case; Black can force the further advance of the pawn. Your ...

It won't be terribly common, but it's not unheard of either. Here are a few examples involving well-known grandmasters: Ivanchuk-Csom (1989): [fen ""] [Event "Yerevan"] [Site "Yerevan"] [Date "1989.?...

While it's a somewhat dated source by this point, I'm certain that Neil McDonald's 1995 book Winning with the Kalashnikov covers this 6.Bg5 variation to some extent, and I'm nearly certain that he ...
