Today I Got Hit by a Mack Truck
[D25 - QGA - Janowski-Larsen Variation]

 I've been playing the Queens Gambit consistently for about a month now and it has created more winning positions.  Unlike the Giuoco Piano that produces a more open board ripe for tactical play, the Queens Gambit lends itself toward more positional play.  I feel like I am choking my opponent, forcing bad trades, and limiting my opponent's piece mobility. (I use "choking" a lot when writing about chess, because chess, after all, is the taking away of space.)  My opponent's bishops and queens tend to have very congested roads for play, and a cleverly placed pawn or two can severely limit landing squares for my opponent's knights.  At this level of play, I'm not sure if the opening is more successful overall or if my opponents are simply more comfortable with king's pawn opening.  In any case, the opening itself makes me feel like I've arrived at another level or dimension of play.

At some time in his life, almost every chess player makes a happy discovery—the Queen's Pawn Opening.  The Queen's Pawn offers White a great many advantages, and all of them can be summed up in one word—pressure!  White gets opportunities to control and exert pressure on the c-file, and in particular on the c5-square.  So powerful can it be as to cause, by itself, the collapse of Black's game.

The past couple of days I've been going over some moves for the Queens Gambit Accepted.  Today I had a chance to play it, but unfortunately my opponent did not respond well and completely lost control of the center.  I played well, but the game ends quite tragically.
