I have annotated ten relatively recent games featuring the Urusov Gambit. I had been meaning to offer a Urusov Gambit Update like that for a while, and was finally prompted to action by Steve Doyle and Pete Tamburro's very nice column in The Sunday Star-Ledger (June 17, 2007) which annotated the game Svensson-Tolksdorf, Correspndence 1973-1974 and made positive mention of my Urusov Gambit website. The game they chose, while a typically attractive Urusov blow-out, struck me as rather out-dated, especially since its formerly main line with 1.e4 e5 2.Bc4 Nf6 3.d4 exd4 4.Nf3 Nxe4 5.Qxd4 Nf6 6.Nc3 Nc6 7.Bg5 Be7 8.Qh4 d6 9.O-O-O Be6 10.Bd3?! is convincingly refuted by the simple 10....Ng4! as I discuss on my site. Fortunately, White has other choices at move 10 -- though Black does not have better than 9...Be6 in my view. Doyle and Tamburro suggest 9...h6 10.Bxf6(?) Bxf6 as being better for Black, which it is, of course; but White hardly need oblige by exchanging at f6 since there is no threat on his Bishop with the h-pawn pinned. White should therefore play 9...h6?! 10.Rhe1! with a strong attack.
In any event, Svensson-Tolksdorf is no longer important to "theory," if traditional theory is really keeping track. After all, the Urusov, while very popular at the amateur and club level, is not played by GMs and therefore not likely to receive extensive "book" coverage. For instance, Nunn's Chess Openings, which I have handy, offers only a single line of text and seven brief footnotes (less than a sixth of a page in a 544 page volume). As my extensive analysis suggests, a bit more might be written, though the absence of GM games is inhibiting. There are, however, plenty of interesting games, many by masters (2200+) and even some by titled players. French IM Luc Bergez has added it to his repertoire, and I have annotated a few of his games. But, as my notes suggest, even strong players are not the best guides to the "theory" of the line. The Urusov remains very much an unexplored territory, and therefore fertile ground for the adventurous gambiteer.
