Jan Werle: Latest trends in the King’s Indian Saemisch Variation

1.d4 Nf6 2.c4 g6 3.f3 c5 4.d5 Bg7 5.e4 d6 6.Nc3 0-0 7.Nge2 e6 8.Ng3 exd5 9.cxd5

In this article GM Jan Werle presents recent developments in the variation with 8.Ng3 exd5 9.cxd5. The resulting position can also appear on the board in a Grünfeld Defence and in the Benoni and thus has a high degree of practical relevance. On account of the white pawn chain g2-f3-e4-d5 the plans are very specific. Jan Werle is certain: if White has understood what is going on, he will be able to seize the upper hand! In more than half an hour video running time the grandmaster from the Netherlands presents many tricky manoeuvres and also a series of completely new ideas!

Mihail Marin: Ruy Lopez with 6.d3

1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Be7 6.d3 b5 7.Bb3 d6 8.a4 Bd7 9c3 Na5 10.Ba2

The move 6.d3 in the Ruy Lopez has gained popularity not least thanks to Magnus Carlsen. And the world champion uses this system again and again with success, as recently against his compatriot Aryan Tari at the tournament Norway Chess 2020. In his video Mihail Marin shows a copybook example, and of course it is a game by the world champion! In the Norway Chess Tournament 2020. In this game Carlsen served up the unusual 10.Ba2 – normally after the attack  9…Na5 the bishop retreats to c2. And Tari was already faced with the first real decision: to take the pawn on a4 or not and if so, when? Opening expert Mihail Marin explains the positional nuances of the sideline and demonstrates which decision by Black was responsible for the strategic loss of the game.

"The Brilliancy" of this issue is not presented in video format, but not only the game but also the analysis by GM Ganguly offer a fantastic attack spectacle!

In the "Lucky bag” you will find not only Ganguly's brilliancy, but also 37 extensively commented games! For example, Adhiban Baskaran analyses three Rapid games from the Asia Nations Cup 2020:

Playing 20...b5! Black broke free of the Maroczy bind in Jumabayev,R - Adhiban,B 1-0, only to fatally blunder a couple of moves later.

In the revenge match Adhiban,B - Jumabayev,R 1-0 one week later,

12.Bf5! increased the pressure on the hanging pawns provoking 12...c4, when White instead of the feeble 13.b3 ("I guess I chose this as I classified the position under 'strategy'") should have played the energetic 13.Ne5!

Finally, 38...Kf6?? in Smirnov,A - Adhiban,B 1-0 was "a huge error in judgement and calculation" which cost India the gold. Guess why?
