"Hiding prep'" is a well known cliche in the chess world. When Anand had a slump in form a few years back, it was joked that he has been hiding his preparation for several years now. I believe there are two sides to this phenomenon: Especially going into world championship matches, players sometimes revamp complete parts of their opening repertoire. For ...

I recall these games from his Modern Chess series. Logically, if Kasparov was willing to return to the same position, Karpov believed that it was likely that Kasparov had found a line that resulted in a favorable position for White. Indeed, the moves 10. d3 and 11. Qb3 give White some advantage and Kasparov had a rather pleasant position throughout. Karpov ...

Aronian vs Anand at Candidates 2014 (http://www.chessgames.com/perl/chessgame?gid=1751406) was out of theory after Black's 3rd move, but only because White played an extremely odd opening which will probably never be repeated at the top level. Aronian vs Leko at Morelia-Linares 2008 (http://www.chessgames.com/perl/chessgame?gid=1486033) featured a strong ...

Another famous example is Zvjaginsev in the Russian Championship Superfinal 2005, against ex-FIDE World Champion Khalifman: [FEN ""] [Event "ch-RUS Superfinal"] [Site "Moscow RUS"] [Date "2005.12.20"] [EventDate "2005.12.19"] [Round "2"] [Result "1-0"] [White "Vadim Zvjaginsev"] [Black "Alexander Khalifman"] [ECO "B20"] [WhiteElo "2659"] [BlackElo "2653"] [...

The most bold novelty I have seen in recent chess is definitely the one played by Richard Rapport against Leinier Dominguez Perez on the 2014 Tata Steel tournament. You can find the game here. As a peek of the game, the first moves were: [FEN ""] [White "Richard Rapport"] [Black "Leinier Dominguez Perez"] 1. c4 c5 2. Nc3 g6 3. g4!! I find that Richard ...

No, this was unequivocally not refuted. First, I would consider a line "refuted" if it led to a significant advantage, and there was nothing you could do about it...it is forced. That is definitely not the case. For a very brief moment in time, this appeared to be slightly better for white, but black has since found plenty of resources with Na5, and it has ...

Kasparov took 63 minutes over his response to the ....e3 move, that in itself made the novelty a very worthwhile undertaking from Karpov's perspective. Clearly he found a gap in Kasparov's preparation and often that might be all one needs in a contest between two near equals, especially when the psychological factors are complex and significant.
