This is the story of the birth of modern chess - when the possibilities of chess as an art, a science and a sport all converged.
The point of convergence was a young boy from Louisiana named Paul Morphy. At a time when America was seen as a backwoods nation with little cultural history and even less intellectual impetus, at a time when chess was considered the exclusive property of a few European countries, at a time when the game was played successfully by a handful of men wizened by years, Paul Morphy, in the brief span of 19 months and with seemingly little effort, defeated conclusively every player he met.
While today few non chess players even know his name, he was one of the most famous celebrities of his time and within the hallowed halls of the chess playing community he is considered by some as the greatest chess player of all time.
But this diminutive, unassuming boy rose to fame almost out of nowhere and once he secured his place in history, he retired back into that hazy unknown, shunning the public eye, never again to play serious chess. Not only was he one of great practitioners of the game, but also one of it's greatest enigmas. He's been given the sobriquet, The Pride and Sorrow of Chess.

  • Starting from h4 Lowenthal perhaps saw only ..Qd7 and Qc8 came as a surprise. It was a clever plan to deal with ..b4, just a bad one.

  • Lowenthal got paid really well to lose this. ;)

  • At 10:20, what if you play Be3...attacking the knight and defending g2 with the rook ?🤔

  • I read . Any funny comments! Thanks

  • I see a very cheesey answer, the mouse ran up the clock, and he pushed the pawn ahead two hours!

  • Probably in his mind he had already played g3.

  • Is it possible that this Morphy saga will actually last longer than Morphy's career did?

  • Title is not matching,, for y this title

  • could someone please explain what is agadmator sorry about every time he says "sorry about that" (???)

  • The clarity of Agadmator's analysis is remarkable. He doesn't bamboozle the public with details but sticks to the ideas, always the ideas. Reminds me of Bronstein and Bologdan. Bravo!!

  • Where Is That Twitter Emoji?

  • Anyone know what he actually does when he goes down at 2:08

  • I always wonder why he always say Sorry about that in the beginning. Can anyone fill me in?

  • BTW I think he sacked the pawn to free up the h file for a mating opportunity

  • Did he sell his soul at a crossroads for chess abilities?

  • He clearly tried to develop his king via the h file. I don’t detect any problems with this move...

  • "welcome back to the good stuff" is what my dealer said when i told him the other guys who deal have the worst weed ever.

  • #KnowledgeofChess

  • 3:15 I liked that, "It is at this position that this move has never occurred again."

  • Mouse slip or Morphy's opponents just inexplicably choke under pressure or he's the greatest chess player to play the game.

  • * you find your wife with a black man comin back home early * Antonio: of course this is a terrible blunder, white here loses immediately feel free to pause the video and sorry 'bout dat *sounds of capture capture *

  • ahhh, the good stuff

  • The really weird things that happen to Morphy’s opponents probably have something to do with Murphy being much better than them at chess.

  • It was indeed a mouse slip, when an actual mouse jumped onto the board as Lowenthal moved his piece, leading to the mouse hitting his hand in mid-air which caused the mouse to slip on the board. The event was caught on video in 120fps slow motion and is considered Top Secret by the FBI.

  • The most there could have been retained by Thomson road suite and the other world soon as possible to prepare for your help urgently need to read this and the phone was not able to travel to you soon as you know when would you take a while to breathe freely and confirm that

  • Nice Title 💥💥💥💥

  • Me: *Instantly sees knight captures pawn to end the game.* Also me: "No, that's stupid. There's no way that move would do anything but lose the game. There's no point in even exploring it further." Moral of the story: I need to trust myself and my instincts more.

  • I think he saw that line where the B takes on c5 after Qd7, and missed Qc8,

  • Thanks Agad. How is the Parkinsons? You getting better? Still got them shakes?

  • Perhaps Löwenthal was inspired to play h4 by AlphaZero.

  • Just leaving a coment here...

  • 6 to 1, Yahoo!

  • 11:15 😂

  • #suggestion Mariotti - Gligorić, Venice 1971 It features the strongest opening of all time, which is of course the Evans gambit

  • Thanks for continuing the Morphy saga!

  • Never underestimate the power of dumb dumb.

  • Show the chess match from history of the world

  • When did morphy escape from Willy Wonka's chocolate factory ? King of the umpa lumpa s

  • Can you fix the Morphy Saga Playlist? There are some videos repeated many times.

  • The link is a picture of them playing each other.

  • #suggestions GM Sergio Mariotti vs GM Svezotar Gligoric in Venice 1971, It involves the evans gambit

  • 6:50 and then e5 and white loses a piece?

  • Where is Mr Smiley Face?


  • At the position where he resigned, what happens if white plays dark-squared bishop to D3? The checkmate is defended, black's rook is under attack and once white's rook is captured, the queen captures the knight. So worst case, you lose your Rook.

  • In his mind Lowenthal had already played g3!

  • Lowenthal pushed h4 but didn't know what to do afterwards because Alpha Zero wasn't around yet.

  • It took me a while to get used to all the chess terminology, as a result I did not enjoy your videos much because it sounded like gobbledegook to me. Now that I'm up to scratch I love your videos!

  • May I suggest the Bundeliga game between Erwin l'Ami and Fabiano Caruana?

  • Johann jacob lowenthal, that name is my name too... whenever I go out, the people always shout "there goes johann jacob lowenthal!".

  • You should take your opponent into the future where mouseslips are often made and the path leading out is wide enough for one.

  • Agad is easily one of my favourite SEnewssrs

  • "Castles castles" is the new "captures captures"

  • 6:52 why didnt morphy play Pawn to e5?

  • What happened to Morphy after he disappeared from the chess limelight:

  • mouse slip lol!

  • I might be some idiot because I’ve barely played chess but what if lowenthal played bishop to d4? It would eliminate the checkmate threat while also attacking the rook on f6, and also open up the two files for his rooks

  • It's "inexplicable".

  • 6.00 lowental probably missed that the bishop on E7 was protecting the night on H4 after capturing. So he thought hell get a free pawn on E6 after the night moves toG6

  • So a mouse slip in 1858, must be something like putting a real mouse on a very slippery surface, and the position it ends up in after falling is propably never going to be repeated again?!

  • What size shirt do you wear and do you have a P.O. Box?

  • Löwenthal in the first half - "Oh yeah, it's coming together." Löwenthal at 5:25 - "actually nvm"

  • First time I actually find the move! Such a good feeling

  • I have been uploading chess miniature games, u will love it ❤

  • At 6.59 u can take the bishop then the knight.... M I right...

  • Addicted to your videos and the amazing content! Just wish there was more of Alekhine :(

  • “What kind of mouse slip can occur in 1858”? This wasn’t exactly an era of cleanliness... toilet buckets were emptied onto streets, disease was everywhere... during Morphy’s turn, Lowenthal stood up to clear his head. When it was his turn to play, he walked toward the board, arm outstretched, and just as his fingers grazed his chosen piece... he stepped, and in turn slipped, on a little mouse who had been scurrying around the playing area. His piece was accidentally pushed to the wrong square, and this is how we got the term “mouse slipped”.

  • What about Bishop E3?

  • Sorry 'bout that

  • Why shouldn't he play Bd4 on the move resigned? That would stop the checkmate and also attack the Rook

  • Alternate theories for the seemingly inexplicable h4 by Lowenthal: 1. Lowenthal was suffering from the early onset of COVID-1858. 2. Lowenthal had just finished watching a series of blitz games by Simon Williams and was just way too eager to throw Harry into the fray. 3. The h-file was Lowenthal's main plan for getting his rooks into the attack, but then he became distracted by Morphy's casual demeanor and somehow completely forgot his plan. 4. He thought he could trap the knight with a poisoned pawn but didn't think it through. As intriguing as the first three theories are, I'm going with #4.

  • It was NOT a mouse slip, but rather a momentary lapse of reason. I'm very familiar with this.

  • “Honor was everything those days...”

  • Agadmator is always there for me at the end of the day... thanks Antonio!!!

  • Thats a great title


  • Could be Lowenthal had the illusion that his bishop or queen was on f2 protecting h4.

  • 8:30 "Black's position is just terrible" I think you meant to say white's position is the terrible one...? :-P

  • handslip

  • handslip

  • I found Morphy's move the first time. Now, I am not here to just enjoy the show.😋

  • #suggestion Please do show the game from Black's perspective sometimes

  • Hey guys meet me im a MM Mouse slip Master with my 5th norm of MM

  • this is NOT unexplainable. NOT a mouseslip he was trying to out fox morphy but failed to trick him. but he couldn’t do it because morphy put a spell on you-

  • #suggestion pls show the matches in which barnes and morphy were a team

  • so this guy is just sayimg im better, but lost 7 games in a row 😂

  • Instead of resigning what if white moves Bd4. Yes, you lose a rook for a knight as the Q guards that square, but this move also stops the mating threat.

  • Video title is smart enough to grab views

  • i’m happy it has been a long time that i didn’t predict a move right and i did it with a Morphy’s move !

  • My explanation: Lowenthal probably forgot about the black Bishop on e7 defending the Knight on h4 so that means Qg4 comes with a double attack on the Knight as well as the pawn on e6.

  • best title ever

  • #suggestion Vladmir Kramnik vs Samay Raina 😍😍

  • 6:49, why wouldn't black just play e5?

  • خیلی عالی از اول دوباره نگاه نمی کنم :heart

  • Morphy had a voodoo doll of all his opponents

  • 2:47 I like to point our that it would be arrogant to presume to understand the thought processes of a genius.

  • dear agad i have found a wonderful game between greg grant vs bobby fisher where grant beats fisher and fisher throws away his king and leaves the match with anger. e4 e6 2 d4 d5 3 Nc3 Nf6 4 Bg5 dxe4 5 Nxe4 Be7 6 Bxf6 Bxf6 7 Nf3 Bd7 8 c3 Bc6 9 Qc2 g6 10 O-O-O Nd7 11 h4 Bxe4 12 Qxe4 c6 13 h5 Qc7 14 g4 O-O-O 15 g5 Be7 16 Bc4 Nb6 17 Bb3 Nd5 18 Rdg1 Qf4+ 19 Qxf4 Nxf4 20 Rg4 Nd3+ 21 Kc2 Nxf2 22 Rgg1 Nxh1 23 Rxh1 Bd6 24 Kd3 c5 25 d5 b5 26 Ke4 c4 27 Bc2 Rhe8 28 hxg6 hxg6 29 Rh7 Re7 30 Nd4 f5+ 31 White resigns. thank me later ;)
