Yes, it seems to be drawn. Unfortunately the PGN comments window isn't yet active in the site's PGN viewer, but here goes. 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.Kh4 Kd5? 5.Rf5+! Here we don't even need to consult an engine ...

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"] White has no winning way to break the blockade and make progress. If the blockade is one rank further up the board, though, it can be broken ...

The game ended because of the 50-Move-Rule. From Wikipedia: The fifty-move rule in chess states that a player can claim a draw if no capture has been made and no pawn has been moved in the last fifty moves (for this purpose a "move" consists of a player completing their turn followed by the opponent completing their turn). The last capture was made by ...

This should be a draw as far as I know and the first step is to get behind the pawn with your rook. Now if black pushes the pawn to the second rank it is an easy draw, because he can never move the rook without you taking the a-pawn and if he tries to protect the a-pawn with the king you will just give checks from behind. 8/R6p/6p1/8/8/1k5P/p5PK/r52 w - a6 ...

The Lucena is one of the most important endgame positions to know, and the nickname for it helps a bunch when trying to figure it out over the board. Remember this phrase - "Building a Bridge." The idea is to get your rook to the fourth rank. Although the move looks rather odd, the idea is simple. Once you bring your king out, he needs to be protected. Your ...

In your diagram/game, black is allowed to set up a Lucena position and therefore wins. However, with correct way of harassing the black king, it is possible to prevent that from happening. After 2... Kc5, you can utilize what's called a frontal defense by playing 3. Rg1. In the lines shown below, black simply cannot proceed. Note, that this defense may or ...

While the accepted answer gives the correct evaluation of the position and a useful link, I think it is important to detail a little bit more the strategy in this interesting rook endgame. First of all, it is important to notice that Black cannot keep the white king cut away from the pawns. Offering rook exchanges and hiding behind the white rook, the king ...

In general, prophylaxis can be used to prevent the rooks getting on the 7th. This is the preferred defense; common challenging moves are to contest open columns with your own rooks, or to guard the 7th rank squares with your minor pieces. In the case that the rooks are already on the 7th, you should secure the most urgent threats (where your king is or ...

Two connected pawns usually win, but with a+b pawns, there are some positions which are drawn. I do not know which game you're referring to, but here are some examples: [fen "8/8/8/3k4/pr6/4R3/1p6/1K6 b - - 0 0"] (Black to move, from Black's point of view - I forgot how to flip the board.) The black king is cut off on the third row, while the black rook is ...

The best resource I know for endgame statistics remains the ICGA endgame stats. The spreadsheet posted there contains pretty much all endgames up to 6 men. So for example KQKR is found in row 27 (assuming White has KQ), with the following percentages: wtm btm W win 99.01 65.51 draw 0.80 5.83 B win 0.19 28.65 So as long as White has the ...

One question to ask is "am I behind or ahead?" If I have some winning edge, it's best to simplify. If I'm behind, it's better to complicate the position. After that, the question has both tactical and positional elements. If my rook is less active then my opponent's, it's better to exchange. If my rook is more active, then it's better to keep it.

This is a very late answer, but if you check 7-piece Lomonosov tablebases, it shows the original position is a draw. Here is a link to the proof.

All of the Syzygy tablebases are available here: https://syzygy-tables.info/ These cover all endgames up to 7-man, and provide WDL (win-draw-loss) and DTZ (distance to zeroing move) data. Syzygy also distinguishes between a theoretical win or loss that can actually be forced into a draw by the 50-move rule, and one that cannot. Here's an example for ...

According to Wikipedia, citing Fundamental Chess Endings, such endgames are wins for the side with the queen, unless there's an immediate draw or win for the side with the rook. However, such endgames are complex enough that even a grandmaster may not necessarily win before 50 moves.

As we can see from the other answers, there are two things you should avoid: 1) The pawns getting blockaded. 2) Your king getting cut off from the pawns. It is not the only way to win, but as a matter of technique it is a good thing to advance the h-pawn before the g-pawn. In this way your king can use the g-pawn to hide both from checks from the side and ...

There exists a 7-men-endgames tablebase available online, the "Lomonosov endgame tablebase". see : http://chessok.com/?page_id=27966 Unfortunately, it is not free yet.

Yes of course, there are more chances for white who has 5 connected pawns to wins instead of black who has a rook. A rook can't check the king all the time and the pawns are always helping each others to get to the final state to get a queen. This problem is usually won by the 5 pawns.

As Glorfindel notes, the Lomonosov tables are great but might not have the answer you want. In RPP/RP, according to the list in this article by Guy Haworth, we find that the maximal distance to mate is 200+ moves, from the following position -- which happens not to have the White pawns connected, but worse for your purpose, it looks like most of the play is ...

Geller himself analyzed this endgame in The Application of Chess Theory. I'm not sure if it's quite as in-depth as you're looking for but I've reproduced the post-move-33 annotations here. [FEN ""] [StartPly "65"] [StartFlipped "1"] [Event "Curacao Candidates"] [Site "Willemstad CUW"] [Date "1962.05.16"] [EventDate "1962.05.02"] [Round "9"] [Result "0-1"] [...

By definition if there's a "winning side" and a "losing side" then the question is already answered :-) But seriously, if you just want K+R+P(d)+P(g) vs. K+R, that's within database range, so you can explore for yourself here. In general such positions are easy wins (note that the defending King can "always" be cut off from one pawn or the other by a Rook ...

48.Kf6 should be winning. After say 48...a2, white goes h4-h5-h6 and something involving ...Rh1, Rxa2 Rxh6+, Kg5 followed by Re2 will lead to the Lucena position. Much earlier on, I believe 31.Kg3 is winning, but it's also the best try by elimination: without an active king (which is the most important non-trivial factor in rook endgames), white won't be ...

Black has an extra bishop and two extra pawns. Black is completely and easily winning, and white can't do anything really constructive. Black's easiest way to win is to promote a pawn to queen and then checkmate white; that in turn is easiest if white's rooks are exchanged off (take all rooks off the board, and black just plays a5, a4, a3, a2, a1=Q). So ...

The following explanation is for the general 3 vs 2 pawns on one side situation, which does apply also to this game. Of course the situation is the same whether the pawns are on the a-c files or on f-h files. This is a fairly simple draw if you follow a few simple rules: don't exchange rooks do exchange pawns whenever possible keep your king close to your ...

You most likely played 50 moves without a capture or a pawn move. This is called the 50-move rule, which results in a draw. Check back to around move 28. You should see the last capture/pawn move there.

Here's an example between two super grandmasters: [White "Laurent Fressinet"] [Black "Vladimir Malakhov"] [Event "FIDE World Cup 2013"] [Site "Tromso"] [Date "2013.08.16"] [FEN "8/2r5/8/6R1/3k1Pp1/6P1/2K5/8 w - - 4 59"] 1.Kb3 $4 ( 1.Kb2 $1 { The only winning move. } Rb7+ 2.Ka3 Kc4 ( 2...Ra7+ { Continuing to check like this isn't useful, as the king just ...

If you ask only about the R+2p vs R endgame then no, it was drawn. In serious engine tournaments the stronger engines usually have access to 6-men tablebases, so they play these endgames perfectly. If you ask about the whole rook endgame, then 45.Kh3 looks like a good winning attempt, as black has no easy way to transpose to the game, e.g. 45...g2 46.Ra1 ...

The 7-men databases from Lomonosov are available for free via their Android app. I've analyzed the traffic between the app and server a while ago, and discovered that it's easy to 'fake' your own calls to the server, so you're not depending on having an Android device nearby anymore. IIRC it worked with FEN strings. I don't have the specifics anymore, and ...

White has a very simple strategy to win this position - Prevent the g-pawn from being captured for free by the Black king (the Black rook cannot capture it because it is tied to the defense of the a-pawn promoting on a8. White wins if White can win the h-pawn) Move the White king over to support the promotion of the a-pawn. At the right moment, occupy the ...

The original endgame might very well be a draw due to the open position and the large number of weak pawns. The position after 45 .. Kd6? is won for white...until 48. f6?. You needed this square for the white king in order to escape from rook checks. Could have won with 48. h4.
