The Queen’s Gambit Declined Course

October 15, 2021 NigelD

The Tiger Chess Queen's Gambit Declined Course is an advanced, stand-alone opening course based around the Tartakower Variaton (1.d4 Nf6 2.c4 e6 3.Nc3 d5 4.Bg5 Be7 5.Nf3 h6 6.Bh4 0-0 7.e3 b6) and the Semi-Tarrasch Defenc (1.d4 Nf6 2.c4 e6 3.Nc3 d5 4.cxd5 Nxd5 5.e4 Nxc3 6.bxc3 c5 or 1.d4 Nf6 2.c4 e6 3.Nc3 d5 4.Nf3 c5). It features amost 14 hours of video which explain key games and has a pgn (portable game notation) file of recommended variations that can be built upon, extended and important into software such as Chess Position Trainer. The 94 games presented are also included in pgn format, but without annotations.

The Queen's Gambit Declined has many advantages, not only is it rock solid but it offers prospects of outplaying the opponent in complex middle game positions. Unlike many defenses to 1.d4 it can also be used against the English Opening, 1.Nf3 and 1.c4. The recommended lines differ considerably from the Queen's Gambit Declined presentation in the Building an Opening Repertoire course, here are the different section headings:

1. Introduction
2. Divergences & Move Orders
3. 6.Bxf6 & 6.Bf4
4. Tartakower: 8.cxd5
5. Tartakower: 8.Be2
6. Tartakower: 8.Rc1
7. Tartakower: 7/8.Qc2 Lines
8. Tartakower: 8.Others
9. Tartakower: Early Rc1 Lines
10. Semi-Tarrasch: Auxiliary Lines
11. Semi-Tarrasch: e2-e4 Sidelines
12. Semi-Tarrasch: 11.Bc4 Main Line
13. Queen's Pawn Games
14. Catalan, English & Reti
15. Other Openings

The Tartakower variation has been played by some of the greatest players in history, including World Champions Boris Spassky, Anatoly Karpov, Garry Kasparov, Vladimir Kramnik and Magnus Carlsen. Here is the starting point for this famous line:

The Semi-Tarrasch complements the Tartakower perfectly as it can be used to recapture on d5 with a knight if White tries to use the Exchange Variation. It can also sidestep White's 5.Bf4 line that arises after 1.d4 Nf6 2.c4 e6 3.Nc3 d5 4.Nf3 Be7 5.Bf4 because Black will play 4...c5 before this happens. This is a key position from the Semi-Tarrasch that arises after the moves 1.d4 Nf6 2.c4 e6 3.Nf3 d5 4.Nc3 c5 5.cxd5 Nxd5 6.e4 Nxc3 7.bxc3 cxd4 8.cxd4 Bb4+ 9.Bd2 Bxd2+ 10.Qxd2 O-O:

This course is suitable for players over 1700 Elo who want a high quality defence against 1.d4 that is strategy based. You need to be a Tiger Chess member to get it and continue to view it, which is why it priced at just $19.95. You can get it at the add-on videos page but need to be a logged on Standard or Premium member to see the option to purchase it.

SEPTEMBER 2021 CLINIC

October 6, 2021 NigelD

I recently took the decision to change the clinic content so that it covers the Tiger Chess Themed Training events on Lichess. I set these events up so that students could practice important position types rather than waste time on the random mayhem that usually occurs in online games. The results have been very promising in that several people have reported increased engagement and interest in the problems after having wrestled with them in a series of games.

The first position to have been played is a key position in the Queen's Gambit Declined Exchange Variation, arising after the moves 1.d4 Nf6 2.c4 e6 3.Nc3 d5 4.cxd5 exd5 5.Bg5 Nbd7 6.e3 Be7 7.Bd3 O-O 8.Qc2 c6 9.Nf3 Re8 10.O-O Nf8. This is a very useful position from which to learn strategy because of the clarity of the pawn structure and the ease with which the different plans and ideas can be explained. Nonetheless it can prove very challenging to master as these plans come into conflict, and I am devoting the current series of webinars to its mastery.

I will not show any highlights this time but instead list the forthcoming practice events, which are held at 8pm London (UK) time on Wednesdays and 6pm London (UK) time on Sundays:

October 10th (6pm): QGD Exchange Training

October 13th (8pm): QGD Exchange Training

October 17th (6pm): QGD Exchange Training

October 20th (8pm): QGD Exchange Training

October 24th (6pm): QGD Exchange Training

After this series the webinars will cover a new topic and new positions will be used for the training events. It will take more practice than this to get in tune with these position types, but this is at least a start.

THE FRENCH DEFENCE COURSE

November 24, 2018 NigelD

The Tiger Chess French Defence Course is an advanced, stand-alone opening course which builds on the treatment of the French presented in the Building an Opening Repertoire course. It features over 11 hours of video which explain key games and ideas plus a pgn (portable game notation) file of recommended variations that can be built upon, extended and important into software such as Chess Position Trainer. The 88 games presented are also included in pgn format, but without annotations.

The French is an excellent defence to choose as Black, it is solid and helps foster positional understanding. The choice of variations is designed to make it easy to learn and remember, with the focus being on reaching and playing certain typical key middle game and endgame positions. All the variations are examined more deeply than in the Building an Opening Repertoire course and some new lines have been introduced.

The main change from the Building an Opening Repertoire lines is that are new ways of meeting both 3.Nd2 and 3.Nc3 instead of the Rubinstein Variation with 3...dxe4. Against 3.Nc3 it is still possible to reach a Rubinstein after 3...Nf6 4.Bg5 dxe4 5.Nxe4 Nbd7, though in this case White has lost many of his best anti-Rubinstein options because his bishop already stands on g5. White also has 3.Nc3 Nf6 4.e5 available, but here Black has a good line in 4...Nfd7 5.f4 c5 6.Nf3 Nc6 7.Be3 a6, aiming to get counterplay with 8...b7-b5.

Against the Tarrasch Variation with 3.Nd2 the recommended line is 3...c5 after which 4.exd5 Qxd5 produces a pawn structure that is very similar to those that arise from the Rubinstein Variation. Black often obtains a favourable endgame by centralising his king and then advancing his kingside pawns. White has a major alternative in 4.Ngf3 after which the recommendation is 4...cxd4 5.Nxd4 Nf6.

The recommended line against 3.e5 is still 3...c5 4.c3 Nc6 5.Nf3 Nge7, but the lines are examined in greater depth and with more ambitious options on offer for Black. The same is true of the Exchange Variation where 4.Bd3 is answered by 4...Nc6 and 4.Nf3 by 4...Bd6. There is also the same plan against the King's Indian Attack and 2.Qe2 lines where Black delays playing ...d7-d5 until he has castled so as to make room for his knight on e8.

This course is suitable for players over 1700 Elo who want a high quality defence against 1.e4 that is based on plans and strategy rather than tricks and traps. You need to be a Tiger Chess member to get it and continue to view it, which is why it priced at just $15.95. You can get it at the add-on videos page but need to be a logged on member to see the option to purchase it.
