Cool puzzle, and the presentation is flawless. The center of attention is the board and moves, the diagramming is precise, the explanations are concise, and the diction is clearly understandable with the emphasis on the moves and the right speed and intonation. It keeps moving, not hanging up on peripheral variations.

4:34 Rook to E5 looks interesting as you can force the king into the H file, but then you can't deliver the coup de grace because the promoted Queen on A1 prevents it. Happy to say I saw the first part, but the last part with the rooks I was way off.

[Amoeby]

4:22 I guess I see the idea and the reason why we needed go exactly here in order this idea to work.
We go Re1 and if black takes we have Rh8 which would be a skewer on the next move if black gets a queen or move his king on the second rank. 5. Re1 Kxe1 6. Rh8 a1=Q 7. Rh1+ or 6. ... Kd2 Rh2+.

It is fascinating that if we went for this trick earlier black's king would be close enough to defend the pawn and the best we can do is throw perpetual checks and get a draw. At the same time if we threw another check on f8 and tried the same thing then black's king is close enough to the h file to stop our rook from getting to h1 or h2.
4. ... Kf2 5. Rf1+ Kg2 6. Rf1 Kxf1 7. Rh8 Kg2 and white can resign. White probably still can get a draw after 5. Rf1+ because two rooks should be enough to capture the rest of the pawns and protect the king but it would be a missed win.

This is actually genius. It's just a shame that I have trouble visualizing the board after any x+1 moves, it made it too difficult for me to work out this puzzle

[Drawfill]

I really like your puzzle videos. You always pick fun ones!

[TimeTraveler-hkxo]

I found the first bit of the puzzle solution but couldn't figure out what to do if the black king would hide behind the white king. Upon further study after watching the solution, I noticed how it's important to sacrifice your rook on E1 specifically. Saccing it on D1 wouldn't work, because the king would be able to get back in time to defend its pawn. Saccing it on F1 would mean the king would be able to defend the key square H1 in time, preventing the skewer. Fun puzzle!

Rook endgame is tricky. This is absolutely true and fascinating!

[leefisher]

Got it! I've learned a lot by looking at your channel.
The king castles, moving up to G7, as the rook moves down to G5.

That was incredible and honestly 100% i didn't find it...amazing.

after watch this video, i notice that i am still stupid

King to c file opens up rook to take first of two pawns, them getting queen doesn't really help as you can lock them into check over and over until you force the queen to block and take it, or setup the fork.

[gheorghebirca]

Rg1-b1+, Kc3; (to prevent R going to c1)
Rc8+, Kb2
Ra8-b8+, Ka3
Rc1. Here white just move K or Rb7 and back to b8. White is just waiting for black to run out of movies and move his pawn to a1, at which point white Rc1:a1x Check Mate.

This appears to be the way for white to win, the key here I think is for R from g8, to get to c1. Now after pause let’s see if I am right.

[brunomaelstrom]

If I did not screw it up, you can count me in the 1% ☺️

1 Rg-b8 +
If the black king goes to the a column, then Rxa7, Ka5, then Rxa6+, then Ra8+ and Rxa1 wins
The king has to go towards the right side of the board and down the board in order to stop the rook from reaching the first line :
… Kc3
Rc8+, Kd2
( if Kb2, Ra-b8 and Rc1 on next move wins)
Rd8+, Ke2 ( if Kc2, Ra-c8+, then Rd1)
Re8+, Kf2
Re1 !! (Forcing the black King in the first rank !)
…Kxe1
Rh8 !! Wins the game because the rook reaches the first rank or the second rank
If a1 = queen, Rh1+ and Rxa1
🥳

You should have also talked about how white had to force the king to the F file specifically. Had white moved the rook to the first rank while the black king was on the E file, the king would have been in time to defend the pawn before the second rook could attack it.

[mikedavis]

I've actually figured this out by thinking to always give checks to force the the enemy to just move his king then I realized what more I can do after that. I am suprised I actually got that although the thumbnail says it's only 1%. Grandmasters, I am coming for you.

[billprovince]

I looked for a bit at Re5 (instead of Re1) with the idea of building up a ladder: e.g., a1(Q), Rf8+ Kg[any] Rg5+ Kh[any], and my idea was Rh8?? however, that just fails to Qxh8. White can try some checks along the f file, and then eventually give up (when black plays to h1) and play Rf7 threatening mate at h7, but black should be able to check often enough with the queen to hold the draw.

[interesting]

btw at 2:09 white can't take on a7 trying to ladder mate because the black king runs all the way to the g file to find safety behind the opposing king

[whelmking]

First one of your harder puzzles that I saw all the moves. Super fun!

[ValkyRiver]

It’s worth noting that only that square works; if it’s on d1, black can take and head for the pawn; if it’s on f1, black can head for the h-file
