Can the King enter the box? – Beginner to Chess Master #18

This is video #18 from the “Beginner to Chess Master” playlist. There will come a moment in an endgame where we must determine if a king can successfully catch a passed pawn, or in other words be in time to successfully hunt down a pawn. What approach do you take exactly to figure this out? Do you calculate, count, and/or visualize both the king and pawn moves? Illustrated in this video is an efficient technique that avoids any calculation/counting, or visualization mistakes when determining whether the king can catch the pawn or not. Are you familiar with this “artistic” method? Addendum: I should have noted in this video that one must be careful when applying this method to pawns on their home square, since they can of course move 2 squares on their first move. Be careful, and double check! 😀

Beginner to Chess Master Playlist:

I’m a self-taught National Master in chess out of Pennsylvania, USA who was introduced to the game by my father in 1988 at the age of 8. The purpose of this channel is to share my knowledge of chess to help others improve their game. I enjoy continuing to improve my understanding of this great game, albeit slowly. Consider subscribing here on YouTube for frequent content, and/or connecting via any or all of the below social medias. Your support is greatly appreciated. Take care, bye. 😀



  1. I remember this trick.

    Thanks again, Jerry. I believe that I have watched every one of your videos for the past four or five years.

  2. I've been waiting for this, was watching every day if you uploaded a new episode of this series, thanks 🙂

  3. Another trick is that knight positions either 2 squares diagonal or 3 lateral are hard to reach…that's really useful too (from a previous video 🙂 )

  4. Hey Jerry, thanks for that video, yet another great one. I came to your channel a long time ago and I am watching every single one of your videos, even though I am rarely leaving any comments.
    I think though that it might have been good here to go into some more detail on this technique, for example a puzzle where one of your own pawns obstructs your king after the capture of an enemy pawn which would have promoted otherwise.

  5. This doesn't work if the pawn is on its starting rank, as the pawn gets to move twice. You might want to annotate that.

  6. Thank you so much for all your hard work, Jerry. A new video from you always makes my day. =D

  7. Hi Jerry. Great video as always. Could you do a lesson on opposite color bishops? Thanks.

  8. jerry, nice trik, thanks god I did not skip this video.

  9. I wonder why somebody would dislike this kind of content

  10. THANK YOU SO MUCH !!! This playlist is just EXCELLENT ! I learned and improved A LOT after watching these great videos !

  11. Your voice sounds a little foreign. Why?

  12. You're so good at teaching chess. You deserve all the support you get.

  13. thank you Jerry. what about other pawns? do you have a technique?

  14. Great video, now i dont have to count all the time 🙂

  15. One of the few things I learned from Silman… before I got a migraine from all the variations in his other stuff

  16. What if the white King is on a6, black pawn on c5, King to move. King cannot enter the box, but can catch the pawn. Right?

  17. omg this is the most handy thing ive learnt in chess! The amount of times I've spent double and triple checking if my king could reach a pawn is unreal. I sometimes even get it wrong because i miss count or visualize it wrong, thank you for this!

  18. I'm kinda lazy, what about visualizing just a right triangle instead? Of course you miss out of the double entendre, but did I mention I'm lazy?

  19. Wish that formula worked for me when i was a kid and had to run AFTER the school bus…

  20. I can see it, how cool is that. It's just there.

  21. This box was mentioned in a book I was reading but I never knew what it was referring to, thanks for this handy tip!

  22. This is not King & the Box.. it is rather Out of the Box (Thinking)!! Thanks for sharing this!!

  23. In the first example – how can I tell whether or not the black king can stop the white king from reaching the h file?

  24. another very helpful video thanx jerry for the great work !

  25. This won't work if the pawn hasn't moved yet (aka can move 2 squares on the next move). For those situations, the king must already be in the box or it won't work.

  26. I'm only two minutes in and I am convinced this man is a genius.

  27. omg, this is amazing! This is a huge help, I've been in so many situations where I was off by just one square

  28. You're amaaazzingggg ♥️♥️♥️

  29. Hmn. I'm new to chess and I just wanna share that I was here. It's kinda sad for me that it was active 4 or 3 years ago, it's nostalgic it makes me cry lol.

    Btw the date's December 21, 2020.

  30. thanks for the video! quick question, what if black's king advances to guard his pawn as well? white's king will not be able to come too close to the pass pawn.

  31. You remind me of Organic Chemistry Tutor. You both are one of my favorite people on that planet. Thank you for existing!
