{ In this chapter, we're going to look at a common rook endgame idea where both sides have a Rook, but one side has a pawn on the 7th-rank and their Rook is passive, or "trapped", in front of the pawn.

If Black's King is on any of the red squares when it's White to move, this position is a draw.

With Black's King on b6 or b7, Black will simply capture the pawn on the next move.

With Black's King on c6 or c7, Black will play Kb7 on the next move and be able to either capture the pawn or occupy the promotion square by playing Ka8.

With Black's King on a1, a2, or a6, it's impossible for White to move their Rook away from the promotion square with tempo as no checks are available. White either has to move their Rook and lose the pawn, or move their King. The White King has nowhere to hide, so black can just check White forever.

If the black King is on any square other than the red squares, it is a win for White.

With Black's king on d7, e7 or f7, White can play Rh8. Black can't respond with Rxa7 due to Rh7+, winning the rook on a7. The best Black can do is to delay the eventual loss.

With Black's King on any other square not mentioned, White can move their Rook away from the promotion square with a check and promote their pawn on the next move.

*Special thanks to the practice mode in lichess.org for the information I will display on these chapters. [%cal Ga8h8] } 1. Rh8 { We are now threatening to promote.

For those of you at the lower end of this rating range, take your time and try to see why other ideas may not work out. For those at the top, master these positions so you can nail them in blitz games!

Please check out the first three studies in this series before continuing. Understanding of the prior studies will be assumed throughout this study.

* Beginner endgames you must know https://lichess.org/study/wukLYIXj
* Intermediate endgames you must know https://lichess.org/study/UsqmCsgC
* More endgames you must know https://lichess.org/study/xtDSXkyi

Once you're done, you can check out my next study in this series: Rook endgames you must know! https://lichess.org/study/bnboDhFM

Throughout this study, I will also provide general endgame tips that these important endgames showcase. Whenever this general advice occurs, I'll write it just like this:

{ We're up a pawn, but black's king is so active that it should be clear that we can only hope for a draw from this position. Can you visualize the resulting pawn race without making a single move? One wrong step, and we could be hopelessly lost! } 1. Kd5 $3 { The only drawing move! By avoiding the f file, we ensure that f1=Q is not with check. By avoiding the a1-h8 diagonal, we ensure that black cannot skewer our possible queen with Qa1+ and Qxh8. } ( 1.

With our king on d5, however, this is a perfectly drawn queen vs queen endgame as long as we keep our king off the long diagonal, avoiding that one trick.

{ As we have seen from our king and pawn endgames, many endgames come down to a single tempo - one player queens and the other player is one square away from queening. In these situations, it's crucial to know which positions are won and which are drawn. As we shall soon see, this is one example where white is winning. } 1. Qf4+ Ke1 { If you are defending this position, you should in general avoid blocking your pawn. The threat of queening prevents white from bringing up the king in the endgame. } 2. Qg3+ Kf1 3. Qf3+ { This is the key position white should aim for. White forks the king and pawn, so black is obliged to step in front of the pawn in order to defend it. } 3... Kg1 4.

Qd1# { The general rule is: the queen is better than the pawn if the pawn is a knight pawn or center pawn (b,g,d,e files). Otherwise, the position is drawn. Let's now see why... } ( 21. Qf3+ Ke1 22.
