Winning starts with what you know
The new version 18 offers completely new possibilities for chess training and analysis: playing style analysis, search for strategic themes, access to 6 billion Lichess games, player preparation by matching Lichess games, download Chess.com games with built-in API, built-in cloud engine and much more.
Recently ChessBase has hit upon a formula which I suspect will be a great success: they've introduced a series of videos limited to an hour, and available by download, called '[X]...in 60 minutes', e.g., Attacking the Semi-Slav with g3 in 60 minutes by Robert Ris or An Anti-Sicilian Repertoire in 60 minutes by Loek van Wely. It seems to me that this is perfect for the average player, for whom six-hour presentations are somewhat intimidating, and for the everyday worker require the patience and consistency to split into various viewings over what might be a week or two. The '60 Minute' series videos are more focused and require only one session or at most two for the average player, and they cost less than the full-length ones (9.90 Euro). For me, the requirement to download is actually a benefit: I get the product more quickly and save shelf space.
Pressing Straightaway: The London System 1 d4 d5 2 Bf4 in 60 Minutes;
(Download); Henrik Danielsen; ChessBase (2012)
Let's look at a couple of examples. Of the 24 '60 minutes' videos by ChessBase. Only two are not about openings, showing again how players are ever-hungrier for opening knowledge; this is a trend which shows no sign of stopping. I've been researching the London System recently and watched Henrik Danielsen's Pressing Straightaway: The London System 1 d4 d5 2 Bf4 in 60 Minutes. This isn't a complete London System repertoire, since it only covers lines with 1...d5. This is a large subject, however, and includes a wide variety of combinations, e.g., ...d5 and ...e6, ...d5 and ...g6, ...d5 and ...Nc6, and ...d5 and ...c5, and others. Danielsen has a lot of experience playing the London, and not only gives a repertoire versus Black's most common setups, but presents some new ideas.
Danielsen's solutions to an early ...c5 and to Grunfeld structures with ...g6 are excellent, and he's convincing in his claim that Black will have a difficult time fully equalising in all these variations. Obviously, anyone who plays the London on whatever level will want to have this video. For a more general treatment on the London versus all defences, ChessBase has Nigel Davies' London System from 2008, in DVD format, whereas traditional readers may prefer the comprehensive treatments in the books Play the London System by Cyrus Lakdawala, and Win with the London System by Sverre Johnsen and Vlatko Kovacevic.
