The opening itself isn’t really a bad opening and it lends itself to a host of transpositions. e.g. the Scandinavian Defense, Scotch 4-N’s, Three Knights, Nimzovich Defense, Owen’s Defense, the Dutch, From’s Gambit, Blough Defense and the Latvian Gambit. My opponent often plays these little explored openings.
In this game I had a slight advantage as a result of having more space, but White’s real problem seems to be tied to the fact that for the entire game his light squared B was out of play, ending up on a2 where it remained until the end of the game. If this is indeed the source of his problems, then it seems to me that it throws the whole line he chose into doubt. This game was the last in the tournament to finish and allowed me to gain first place on tiebreaks.
