Attack vs. passivity?
David, that was such an inventive & clever attack you played against me yesterday! Do you remember how we proceeded from the 11th move? I know that within another 4 or 5, you were a piece up for a couple of pawns or so, and with a strong king-side attack still in swing.
And already you could be ahead, materially, with 11.NxR. If 11...QxN then 12.BxB Pc7xB ... and black has a backward pawn on d6, and is down "the exchange" (minor piece for rook) with only a pawn in compensation. But was that enuf for you? Oh no. You wanted my king, and you wanted it now.
