Yesterday and today we are having an interesting day! Smoke from Canadian wildfires in Ontario, roughly 500 to 700 miles away, have made the days appear cloudy and there is a strong smell of smoke outside. Looking out my back window I can see a haze of smoke across a nearby church’s parking lot. The Environmental Protection Agency has issued an air quality advisory because of very unhealthy to hazardous particle pollution.
Recently I was debating whether or not to enter a Lechenicher SchachServer theme tournament in which 1.d4 f5 2.Qd3 was mandatory, but waited too long and the tournament filled up.
This line looks fascinating and I had an idea I wanted to try. My database turned up 197 games where white played 2.Qd3 and white’s scored +77 -72 =48, so it’s certainly not a drawing variation!
My idea while taking a quick look at it was to play 3.g4?!, but it’s been done before! In my database white has scored +23 -22 =14. In today’s game white used it to defeat the redoubtable Gata Kamsky. It makes me sorry I didn’t get to enter the tournament.
The move 2.Qd3 is an unusual response often played to throw an opponent’s preparation off. The 365Chess Opening Explorer calls it the Manhattan or Ulvestad Variation.Aside from surprising an opponent the move does have a purpose. It’s immediate aim is to control e4 and discourage black from playing the ...e6 setup. On d3 the Queen also has some potential tactical possibilities because it prepares for a quick Pawn advance to e4, or maybe even a K-side Pawn rush. It delays development though and so allows black several ways to equalize by taking control of the center and developing naturally.
