this line is 1.e4 c6 2.nf3 d5 3.nc3. it was played by bobby fischer in his youth. white gets rapid development and has options with the d-pawn. black's logical and probably best reply is 3...bg4. after 4.h3 bxf3 5.qxf3, black has the option of 5...nf6 or 5...e6. 4...bh5 is a complicated line, in which white can trap the bishop, although black has much compensation.
