I need help deciding if I should allow the NID or the QID as white. I play both Nf3 and Nc3 vs. the QGD and nearly all of black's defenses. This choice will not affect the rest of my repertoire. At my level (1750ish USCF and improving fairly quickly), very few play the QID. I had my first taste of this opening in my last tourney. To give you an idea of the poor quality of our level of play, the game is here:
http://www.mrfixitonline.com/viewtopic.php?t=7520. I'm looking for a white system that is a tad more agressive and less drawish.
The goal of my repertoire is to aim for strategically rich positions with moderate tactics. As black I play the Ragozin QGD and I am learning the black side of the NID. I defend the open games (2 knights defense and fianchetto lopez), but I simplify the f4/d4 gambits (early d5). I play 1.d4 aggressively vs. the QGD (5.Bf4), but I am more cautious vs. the Benoni (Nf3 and h3), etc. As white I cherish a space advantage and as black I'm stubborn about staking my claim in the center. Any thoughts would be appreciated on the merits of these lines for players in the 1800-2200 range.
Petrosian QID: 1. d4 Nf6 2. c4 e6 3. Nf3 b6 4. a3 Bb7 5. Nc3
These lines appeal since i get the same Nc3/Nf3 formations I use vs. everything else.
Kasparov NID: 1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. Nf3
The early Nc3 and Nf3 avoid transposition difficulties within the rest of my repertoire.
Open Samisch NID: 1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. f3
This would break from my general desire to play Nf3/Nc3, but I do like a big center.
