Paulsen Variation of the Petroff

diagram White to play after 15...Nxe3
One of the main reasons I started playing the Bishop's Opening (1.e4 e5 2.Bc4) was to avoid the annoying Petroff's Defense (1.e4 e5 2.Nf3 Nf6) which always seemed to me rather equalizing. You can't even be sure of getting a Urusov Gambit against it since after 3.d4 Black does not have to play 3...exd4(?!) 4.Bc4! but could simply play 3...Nxe4, which is pretty dull looking. Likely if I looked at some lines deeply enough I'd find something to like about White, but it is all such well-theorized territory that it sort of puts me off trying.

Recently, though, I stumbled upon a game with the Paulsen Variation (1.e4 e5 2.Nf3 Nf6 3.Nxe5 d6 4.Nc4!?) which intrigued me enough to annotate it closely and to think that facing the Petroff might actually be interesting with a line like this. Some of the variations remind me of the Saemisch Variation of the Alekhine's (with 1.e4 Nf6 2.e5 Nd5 3.Nc3 Nxc3 4.bxc3) which I have played on occasion, and though Black certainly has chances you get lots of unusual positions with lots of interesting strategic and attacking play.

According to the book by Forintos and Haag, this line was "first played by Louis Paulsen in 1887, and then resuscitated by Yugoslav players in the 1950s." After that, to judge from the archive, it more or less vanished. They seem to think that Black "obtains comfortable play" and that may be why there is relatively little theory on it out there. Several other Petroff books I've thumbed through, in fact, relegate it to practically a footnote if they even mention it at all. And a search through databases turns up remarkably few games (under 100, in fact). This last fact may be the most attractive aspect of the Paulsen Variation since it suggests there is still a lot to discover in it (an idea reinforced by an intriguing recent victory by Navara over Kostiniuk playing the line in very unusual fashion).

The following game between the young Andrija Fuderer and old-timer Boris Kostic must have been part of the Yugoslav revival mentioned by Forintos and Haag. It is also quite suggestive of the type of deep attacking ideas that are available to White in this line. You can play over the game online in a java applet or download the PGN (or get the PGN as text below).
