    Roman these vidoes are excellent, you really have inspired us to master nimzo indian! Thanks a ton sir :)

    Hope you start doing a similar series on Queen's Indian, I assume since you played nimzo indian you would have had to go for Quenn's India too as many might have avoided nimzo with  Nf3 and so you would have done research on this opening as well. So please sir in case research has been going good please share the ideas with us.

    There is a famous a3 numzo game where Botvinnik is white and Donner is black. Donner won in what is considered by many pundits to be a positional masterpiece of how to counter a3.

    from chessopedia

    4.a3 - The Sämisch Variation (named after Fritz Sämisch) is a direct attempt to refute Black's strategic concept, as White gives up a tempo and concedes doubled c-pawns to gain the bishop pair. After 4...Bxc3+ 5.bxc3, Black has several possibilities, the most common of which is that he immediately begins to blockade the doubled pawns with 5....c5 and applies more pressure on the (often doomed) pawn at c4 with the moves ...Ba6, ...Nc6-a5 and ...Rc8. In the early days of this line, 5....d5 was frequently played, though it was soon realised that this enabled White to liquidate the weakness at c4, so the idea fell from favour, particularly after the game Botvinnik-Capablanca, AVRO 1938, and has never been revived at top level. As compensation, White establishes a powerful centre, in order to play for a kingside attack before Black can make use of his static advantages. White has two main options for playing: he can move slowly into the centre with 6.e3, or he can play 6.f3, followed by 7.e4 to take a quick hold in the centre. In practice, however, Black has demonstrated that White's structural weaknesses are more serious than the attacking chances he gets, so this variation is rarely seen nowadays. The Sämisch Variation was employed five times by Mikhail Botvinnik against Tal in the 1960 World Chess Championship, with five draws resulting, and once in the 1961 rematch, with a win for White.

    Roman this was a brilliant lecture - I play the Nimzo-Indian almost as much as I play Queen's Indian, and this was extremely relevant for my own play and development...

    "..so I assume, you are not yet on the highest level yet."

    No Roman I am not on the highest level yet Laughing but with practice and watching your lectures I someday hope to get at least half-way there...

    You have produced so many good lectures this is clearly one of my favourites! Would you consider doing a similar series on the Queen's Indian defence?...

    2. History

    The move 4.a3 was first played in the game Ferrari-Stalda,1923, and not in Norman-Michell,1924 as some sources tell us. Then the German Grandmaster Saemisch worked out the whole system and started playing this variation regularly. He played his first official game with this variation in 1928 against Engel.

    According to my database, 4.f3 was first played by Bogoljubow in 1931.

    3. The main ideas

    In comparison to the line with 4.e3, where White locks up his c1-bishop and opts for a slow solid development, and 4.Qc2, where in order to keep a good pawn structure White slows down the development, "developing" the queen instead , the lines with 4.f3 and 4.a3 look more tempting - White immediately tries to build up a pawn centre. Often one variation transposes, and that's why it makes sense to study them together and to not only know the exact moves but the ideas in general.

    Playing 4.f3, with the idea of 5.e4, White starts a fight for the centre, which often turns into a sharp battle. The disadvantage of this variation is that the f3-pawn takes the natural square from white knight and the dark squares are being weakend.

    After 4.a3, in comparison with the other variations, where the black bishop on b4 often retreats and is not exchanged for the knight, Black is forced to take the Knight on c3 thus strengthening White's centre, giving White the bishop pair and chances to launch an attack on the kingside. The weak c4-pawn can often be sacrificed for the initiative. The disadvantages of this line are also obvious - White loses a tempo playing 4.a3 and his pawns on the c-file can become rather weak. As a result, a double-edged position arises with chances for both sides. In both variations there is plenty of room for creativity and for new ideas.
