Grandmaster Yasser Seirawan presents a lecture on one of his most important games. This game took place at the 1984 U.S. Championship against GM Kamran Shirazi. Unfortunately, technical problems cut the lecture short.
Considerable shame this was cut short. If chess lessons were as celebrated as the game, I'd have called this Seirawan's Immortal - the whole lecture is the pinnacle of his legendary humour and insights, and he still manages to describe the concepts in a more meaningful manner than any number of the emotionless game analyses one can find on youtube. I think I have a mancrush.
Too bad the lecture ends too soon. After 15.f4 the evaluation is +0 but after 15...c4 it jumps to +2.85, so it seems this was the critical moment in the match.
I love yasser, but someone have to teach him how to use the computer for pointing out the moves he's trying to explain. Pointing at the screen is just not helpful...
I also really wish that this game was finished... I don't imagine it'd be possible for @Chess Club and Scholastic Center of Saint Louis to reupload, huh? :D (Had to try)
Also black played g6, you normally wouldn't push the pawns in front of your king unless you had to (or its in the move order of the opening). The black bishop on g7 controls a lot of centre squares, and defends h6 and f6 that you weakened with g6.
hakaaannnn because black put all the pawns which were infront of his king on white squares. That means the pawns can only defend white squares, and if they wanted to defend dark squares then they would have to move forwards even more making the king even more unsafe. Usually doing this is fine if you fianchetto your dark bishop on g7, so that the dark squares around your king are also defended. But not only did Shirazi not fianchetto his bishop, but he gave his dark square bishop away. In other words, the dark squares are weak because black has no dark squared bishop, so if white were to attack a single dark square with all his pieces, black would be unable to defend it with all his pieces as his white bishop is unable to attack dark squares. Because the dark squares are weak, white's dark bishop is very powerful As well as this, white has many pawns on white squares, which limit the mobility of his own white squared bishop and so it is of less power. And so the value of the dark bishop goes up because of black's pawns being on white squares, and the attacking value of the white bishop goes down as all of white's pawns are on wte squares. So relative to each other, the dark squared bishop is worth much more than both black's and white's light squared bishops
according to chess strtegy light square bishop is strong asset for white than black one.because it can hit f7 square.soft spot.Same way dark square one is strong for black
