How consoling that the best computer software in the World is not a match for a mere human
I sincerely wish you were right, but you couldn't be further from the truth unfortunately 😢. Against the best computer software, humans always loose except for some percent of matches drawn for the best of our species (or if you copy a 100% known game for deterministic engines).
There's an important line that you missed here, if black plays 2... Kh1 then we play a waiting move with the bishop, e.g. 3. Ba6. We allow the promotion, and mate immediately with 4. Bb7 and 5. Bxg2# unless black underpromotes to a Knight. In that case we play 4. Kg3.
Now in response to either 4. Nxe2+ or 4. Nf3 we play Kf2 and the finish is similar to the version you showed. And if 4... Nh3 then 5. Bb2#
Excellent study... lot of learnings... Thank you very much
That is the most convoluted position I've seen you post.
I am on a roll today, solving all 4 of your puzzles that I tried, but this was by far the hardest and I didn't really play out the Underpromotion variations at the end until we go to that part. I was torn between C4 and D5 for like an hour, so I would have timed out. I was trying to use C4 for a checkmate and I finally realized how good it was to have the e2 space protected by the Bishop.
I did find the first move the second one was a nice surprise, so was the final endgame with Bishop against knight.
This problem is a really hard one! Many options don’t work.
After noticing the time length of this study [12.38], I realized that there was NO WAY that I was going to attempt to solve it. Why beat my head against the wall by making thousands of random, errant moves? So, I just sat back and enjoyed the video …
I was duly rewarded for my discretion!
Great puzzle!
I don't think that Magnus Carlson could have solved this.
1:22 Losing in the meaning of we failed to win and just got a draw? :)
Losing, as in, not solving the puzzle.
Very difficult, a true World Champion's study!
Excellent!!
(@5:50) Instead of Bc6, you have Bh1! forcing black into zugzwang! Black must play Kf2, then white just grabs the pawn with Kxh2. Now a bishop and knight can force a checkmate.
I realized pretty quickly that anything other than Nc3 couldn't be winning but I wasn't able to see the win after ...c2 and would likely have thrown the game away with Ne2.
Edit: I doubt I would have *ever* found Kf2 in response to ...Ne2.
Wow!
Found it! 😊 At least the main moves, didn't check every variant!
This is rich! I stumbled every step!
the missed win stockfish was talking about:
I saw the first move, and then I floundered.😂
Same here. I saw the need to get the knight to e2, but missed all the complications that arise after that . . . Very nice but hard puzzle!
At 11:28 it is said that white has checkmate by moving bishop to e4 but what stops black knight from taking the bishop (and putting white in check)?
Black has to move first and he can only move his knight (and drop the protection of e4) so wherever he puts it white has Be4 and checkmate after that.
hint for author: besides inaccuracies, you missed several interesting variants, which make this study more interesting. i recommend redo this video.

Li chess StockFish say Nc3 +99.0
But when you play Nc3
Now black moves g2 is +2.0
I got it under the minute, but would have never search for a win overboard - would have just taken the draw. Looking now - no, I did not see all the lines :), amazing
