Here is a practical example of how to apply the Reti Endgame: • Chess Endgame Puzzle I...
Today we will look at the Reti endgame study. If you are a serious chess player I am sure you will now about this, but if you are just a beginner looking to start picking up chess, this is an important endgame study you should know.
It’s white to play and even at the first glace this seems like visually impossible for white to stop that black pawn or defend his own, this position is actually a draw with the right play. But what is the correct play here?
The Reti endgame study, designed by Richard Reti in 1921, demonstrates how a king can make multiple threats and how it can take more than one path to a given location, using the same number of moves. It’s a must known endgame for all the people who wants to take chess more seriously and can be a life saver in some of your games. I hope you found it useful and as usual if you want me to cover a specific topic, mention it in the comment. Have a nice day!

If you want to see a practical example of the Reti Endgame Applied in a real game scenario, check the video linked in the description!

@crawkn 5 месяцев назад

This seems a bit counterintuitive because diagonal moves are effectively advancing in two directions at once. They give an impression of moving further away from the chased pawn, when they are actually moving closer.

@ChessCrafters-lk4dv 5 месяцев назад

Indeed

@untitled6087 4 месяца назад

This isn't quite precise enough - diagonal moves are only two moves at once because the threats are in orthogonal directions. You can imagine a scenario where there are two threats in diagonal directions, and an orthogonal move approaches both at once, but this is simply less common I think

@crawkn 4 месяца назад

@@untitled6087 The problem in that scenario is that moving in an orthogonal direction "toward" the diagonally located threats doesn't actually reduce the number of moves still required to reach the targets. It gives an illusion of approaching both threats while in reality not approaching either.

@jessejordache1869 3 месяца назад

I was just going to write this, basically: the key to this puzzle is understanding the geometry of the chessboard: moving to h7 or g7 both move you equally close to black's pawn, so why would you ever choose h7? And the same principle applies for each move.

@crawkn 3 месяца назад

@@untitled6087 I thought of a way you can highlight the difference, if you turn the board 45 degrees, you now have rows and columns of diamonds. If you move vertically or horizontally, you are effectively skipping a row, while if you move diagonally, you are moving only one row at a time.

@Paul71H 5 месяцев назад

The key concept that saves white here is that a diagonal move is really two moves in one -- a left or right move plus an up or down move. By utilizing diagonal moves (with the threat of future diagonal moves), the king is able to effectively remain within striking distance of both pawns.

@ChessCrafters-lk4dv 5 месяцев назад

indeed, by moving on the diagonal you can create multiple threats at once, attacking the enemy pawn, while also protecting your own. If you commit to early to one of the action, you would lose the game

@niemand262 5 месяцев назад

Truly mind-blowing. White is neither attacking nor defending, but improving his ability to attack or defend while forcing black to expose his plans first. It's like a positional-tension zugzwang.

At 8:03, if black promotes instead of moving the king to b7, that means white's promotion doesn't check black's king. As long as both players are competent it still results in a draw, but it does put checking power on black's side instead of white's which was not shown in any examples.

You are right, but I feel like this position is an easy draw, even if black checks first so I wanted to keep the video as short as possible

@992ras 5 месяцев назад

If white gets the king and queen first you could ultimately get checkmate by trapping the black king in the conner. It will take 2 moves to trap the black king and 4 moves for the black pawn. If you move wrong then it will become stale mate. Its like the question what piece are you own the chess board the king there been times people could have gotten checkmate on me but they move wrong and get a stale mate while I only have king you really need to learn when and how to move your king it’s not only just piece it can become a weapon as well during end games

@ChessCrafters-lk4dv 5 месяцев назад

I don't think white can promote first, he barely is in time to save this game, maybe if black blunders a lot, and even then it's still hard for black to lose this

@thomasdalton1508 5 месяцев назад

Generally speaking, if you can promote first you will win unless the other player can promote immediately after. You don't need to checkmate before they can promote, since you can just capture their pawn (or their new queen as soon as it is created) and then take as long as you need to checkmate. A queen can get anywhere on the board in two moves, so it can always capture the pawn if it doesn't immediately promote. If the pawn is defended, it's a draw (unless you can do something clever with checks). If the pawn isn't defended (as here), it's a win. If black knows this (and any chess player that isn't a complete beginner will), they won't just try to promote their own pawn but will try to stop your pawn first. That's why you have to defend your pawn at the same time as threatening black's pawn.

@Wi11daThri11 5 месяцев назад

@3:21 looks like a big blunder!! If both pawns start pushing, then white king&queen get skewered along the diagonal as soon as white get his own queen promotion!

@ChessCrafters-lk4dv 5 месяцев назад

Not really, because even if black pawn promote first, white pawn will promote with a check, so black need to respond to that first, after black king move, white can deal with the skewer

@Rob-wg9cf 5 месяцев назад

But he is correct about a blunder in this time frame. The error here is poor play by black. Rather than push the pawn to h2, and allow the white pawn to pass by the black king forcing the chase, the correct move by black is to move ka6 to b6. This forces the white king to move to the d file. Then push the black pawn to h2. White pawn to c7. Black gets its queen. Even if white gets a queen, the black king would not be in check on b6, allowing the black queen to put white in check.

@ChessCrafters-lk4dv 5 месяцев назад

@@Rob-wg9cf it's not a poor play by black. This position it's a draw even if stockfish would play as black. Even if black would play Kb6, white will respond to Kd6, which will not be on the same diagonal as the queen. And even if black queen first and start checking the white king, there is no way to win the queen with a skewer

@thomasdalton1508 5 месяцев назад

The way to think about this is with Pythagoras' theorem. When you move diagonally, you move √2≈1.41 times further than when you move orthogonally (1²+1²=√2²). That means you can cover a lot more distance than you would first expect by moving diagonally. Because of this, the quickest route between two points is not necessarily a straight line (or, at least, it isn't the only quickest route).

@ChessCrafters-lk4dv 5 месяцев назад

indeed, this is what i've tried to do with the graphs

@Rikdewinter 5 месяцев назад

No this is wrong. The trick is to see that Pythagoras DOESN'T apply. Normaly going diagonally is a detour (and pythagoras lets you measure how much of a detour it will be). But on a chessboard this is not the case. Getting from one corner of the board to the opposite border doesnt take √8²+8² = 11.3 steps, but it takes 8 steps.

@thomasdalton1508 5 месяцев назад

@@Rikdewinter You can look at it that way, but I think for non-mathematicians it is easier to think in terms of travelling faster when going diagonally than it is to think in terms of a non-Euclidean metric (specifically, the Chebyshev metric). non-Euclidean geometry is completely alien to most people.

@mohamedyounes4828 5 месяцев назад

Guys E=mc²

@Rikdewinter 5 месяцев назад

@thomasdalton1508 I wasnt talking about Euclidean geometry: It's still a flat surface. But it's a grid. You don't measure distance in decimals, but just by counting squares (integers). So going somewhere on the board by making diagonal moves is not longer. So Pythagoras is irrelevant
