[Event "Austrian League"] [Site "masterchessopen.com"] [Round "0"] [White "Lau, R."] [Black "Steflitsch, E."] [Result "1/2-1/2"] [ECO "A46"] [Opening "Indian: 2.Nf3"] 1.d4 Nf6 2.Nf3 d5 3.e3 Bg4 { This is given as an anti-Colle weapon in some reference books, but the analysis usually stops here. I think White can extract an advantage if Black is not on his guard. } 4.h3 Bh5 5.g4 Bg6 6.Ne5 { White decides to give Black immediate problems. The point is that he intends to follow up with h3-h4-h5 to trap the bishop, and if Black responds with ...h7-h6, then the knight will take on g6 wrecking his pawn structure. } {#d} 1/2-1/2
