Since this is a lecture to an audience, he often asks obvious questions and then waits awhile for the audience to answer. Youtube has a feature where you can skip ahead by 10 or more seconds. On the PC it is done with the right arrow key. On the iPhone, it is done by multiple-tapping the right side of the screen.
This guy wanted to see if he could master chess in 30 days. He improved, maybe going from beginner to 1000 or 1100 in 30 days. On day 30 he has a rematch with a 1500 player that does not go well. I had much to say about that game in the comments section of the video.
Bobby Fischer teaches chess is very much at the absolute beginner level. Game 1 the Ne5 move was way premature, but you explain that.
To really master chess you might want to learn 1. d4. The book "Logical Chess Move by Move" is useful in this regard.
The en-passant rule has to do with the fact that pawns used to only move one square from the start. Moving two squares was a way to speed up the game (and so is castling), so enemy pawns can normally capture your pawn if you move up one square and this is important for allowing pawns to blockade other pawns. En-passant allows a capture as if the pawn had only moved up one square, which maintains the ability to blockade.
My experience is that you are unlikely to reach a memorized opening past move 11. There are some exceptions where certain openings, like the Dragon, don't really get started until around move 10. Everything up to that point frequently follows the same sequence.
In the last game, I don't like 5. Bd3. It is not a great spot for the Bishop, which is serving the purpose of a pawn. The move b2-b4 creates weakness on the C file with a backward pawn on c2. Here your pawn is well guarded but there is a big hole on c3 creating a weak spot that your opponent should try to occupy. Your pieces (bishops and knights) are somewhat passive and in defensive positions, and eventually you will want to get them to better spots. (Grandmasters really like to have active pieces.) Ouch, you got skewered with Ba6! The game is technically lost at that point. The Bb6 response is probably bad. I think that he should respond with Qb7 and try to pin your b6 bishop. He didn't have to capture the queen immediately. Instead of Nb3, the knight taking on e4 makes more sense to me because material is important. When you played Nf6+ (check) you had two attackers on the square and he had two defenders on the square, but you moved one of your attackers to the square meaning that he was going to win the piece. You really need more attackers than defenders on that square to make that move. After he captured the knight it is better not to trade your bishop because you should not trade when you are down material, because your percentage of the total material becomes worse. Likewise, you should not have traded your last piece, but the game is pretty much over by that point. (Overall, you were too anxious to trade pieces. Many beginners do this, but I only trade when I think that it is to my advantage.)
Pattern recognition is a huge factor in this game, and on my website I stress doing tactical exercises to improve pattern recognition.
P.S. Your hypothetical example of where trading pawns might be favorable to Black is really bad because after 1. e4 g6 2. d3?! f5? White can play 3. exf5 and then if 3... gxf5???? 4. Qh5# (checkmate), which is a variation on "Fools Mate."
Perhaps the most important thing is that I didn't make any losing blunders that I know of. I haven't analyzed the games yet. I did fail to win a game that I should have won against a lower rated player and I will be examining how I messed that up.
Between the years 1475 and 1500, a new variant of chess arose called "Mad Queen Chess." The previously weak queen suddenly became the most powerful piece on the board. This made games more exciting and allowed them to finish faster. This is the version of chess we play today, with only minor differences.
I thought that "Mad Queen Chess" originated in England during the reign of Queen Mary I during the 1500s, but it actually originated in Spain in the late 1400sbecause Queen Isabella was a very powerful Queen.
I think that chess is being played now more than ever, but it has shifted to online. When I first got on the board of the Utah Chess Association around the year2000, the membership was down to 500's, compared to the heyday of around 800 to 900. By the time I left Utah, it was 350. Some of this decline happened while I was President of the Utah Chess Association. If it wasn't for the kid's tournaments it would have less than 100.
For those who might be interested, this is a unique mate in 4. I know that some people will say to not focus on the trivial, but I find it interesting because this produces a pattern that I never would have predicted.
The game starts pretty good but has some really big mistakes from both players. I'm not sure how to evaluate the play of the 4-year-old, but it is a good starting point.
Around 2007 or 2008, eight-year-old Kayden Troff had a draw against me in a major Utah tournament. Actually, I was down at least a pawn but figured out how to get to a book drawn ending. Two years later he won the Utah state speed chess championship beating a life master twice. Six years after that he earned the Grandmaster title.
Utah produced a few prodigies, so I was used to losing to kids.
Tonight I had a couple of interesting games against ten-year-old Evan, who has an impressive 1500 rating. The first game I won without too much problem, but the second game was a difficult struggle. Evan plays with a maturity way beyond his years.
Although a couple of moves are inaccurate, this is still an amazing short game by a 3-year-old against a former world champion. Just the fact that he didn't do anything really bad is an accomplishment.
