  1. According to the engine, there are lots of winning first moves for white in addition to Qh1+, such as Qd3, Qf5, Qe4, Qg6. And then, if Qh1+ and Rb1 are played, there are again three winning moves for white: Qh8+, Qg2, Qh2

  2. This would be the most satisfying way to win a game. Great puzzle!

  3. Pretty smart, the king and the pawn is chilling in the corner thanks to the rook๐Ÿ˜‚๐Ÿ˜‚

  4. Fascinating that you can just ignore your own king and pawn and still win

  5. A nice example of trangulation using the queen

  6. Nice. Thank you. I like puzzles in the morning with coffee. Bravo. You've gained a new subscriber. GothamChess has a new rival in my algorithm ๐Ÿ˜ƒ

  7. โคway too big brain for my small little peanut numbskull but I thoroughly enjoyed.

  8. Extended zugzwang where the pawn has to march to its death to delay the king's execution

  9. Love these. I can never solve them, but they are great for getting my chess gears turning. Excellent content, Nelson!

  10. Good puzzle. I did NOT solve it, but having seen the strategy, it seems simple.

  11. Wow. This is the only puzzle Iโ€™ve solved so far.

  12. Odd cycling vs even cycling. My favorite part of chess.

  13. I love the logic but I can't do any of these myself.

  14. I am enjoying these puzzles. I note that many of them involve noticing or creating a counting machine from chess pieces and the solution is to run down the counter.

  15. Why would you need to cycle using the triangle? Canโ€™t you just keep the queen on the diagonal pinning the rook?

  16. Very nice triangle grif !!!! Thank you for that, like all your puzzles, are so instructive!

  17. What happened, Nelson? The puzzles used to be fascinating and really difficult, now most of the puzzles (like this one) i solve entirely in like 15 seconds!

  18. Triangulation is not just for kings!!

  19. Queens are terrifying…I'll trade queens any opportunity I get, lol.

  20. I'm sure everyone has been in this position at least once lol

  21. you didn't need the tringle, you just need to keep the rook pin. With the rook pin his only move would be the pawn just keep the queen on the diagonal.

  22. can you do martin challenges again? i was liking them

  23. You don't need to go right round the triangle the last time. Simply moving the queen along the long diagonal (e.g. to e5) will also force black to move the king, at which point you can drop down to e1 for checkmate.

  24. 1. Qh1+ Rb1 2. Qh8+ Rb2 3. Qd4 d5 4. Qg1+ Rb1 5. Qg7+ Rb2 6. Qd5 Kb1 7. Qd1#
    Gotta say that I love the geometry of this puzzle.
    Edit: Oh, I missed that black can block 5. Qg7+ with 5. … d4 but the rest is similar.

  25. I got this one right, calculating from the starting position all the way until the forced checkmate. I'm proud of myself, this rarely happens.

  26. 1:12 At this point I'd just play Qc1+ to force a stalemate.

  27. awesome videos man. chess never came naturally to me. you are an excellent teacher. thanks. not really interested in playing ha. only the puzzles.

  28. I understand this not because of the depth of my analysis but only because I expect 9 of 10 of Nelson's puzzles to have zugzwang and or repeating a position on opposite color squares.

  29. 4:46 Otto (or Oscar) Blathy used this idea in a lot of his compositions: a sequence of moves for the purpose of gaining or losing a tempo, giving White a chance to do something else (a "free move"), then the sequence of moves repeats itself, and White gets another free move, etc., and eventually wins. He came up with compositions where White was to mate in a few hundred moves.

    The problem could have been improved by also putting a pawn on d7; then White would have to do the triangle maneuver a few more times, and need 19 moves to mate.

  30. This is actually a White-mates-in-10 problem as originally published, not a White-to-win endgame study. As a study it is hopelessly unsound with many ways to win, but as a M10 problem it is correct with one solution.

  31. In 2:44 if white moved the king is this a checkmate ? Because black cant move the rock

  32. This is a satisfying puzzle, because Iโ€™ve found the solution

  33. there's 5 possible first moves for white tho

  34. can u make vid about queen and knight end game?
