I actually reduced the number of mistakes in my OTB games by adopting a pawn push method, changing me from losing to everyone OTB (before adopting 2f3) to winning against a good deal of people (after adopting 2f3). This allows me to easily threaten my opponent's pieces that come out and increase the time advantage by forcing pointless moves at the beginning whilre I build my pawn structure.
I'm not knocking your method, even though it's not optimal, but like I said in another comment 1.d4 2.c3 is by far better - try that and see if your results improve.
Actually, my next move is usually 3. c3 (to guard my central pawn), 3. g3 (to stop a check), or 3. g4 (to begin an attack on a knight)
Thanks, I will. And I already knew that my opening was not considered a good one, but I could rarely find a reason why. This forum has been very instructional.
