1. In the Howell Attack (ECO C81), 9.Qe2, White aims for play against d5 after Rd1.

2. Armstrong's character Patrick is a Blabbermouthed perpetual teenager with a mail-order clothing business and a silver E-type Jag - cunningly shot here to look longer than the QE2

3. Another possibility for White is 5.Bb5+ Bd7 (5...Nc6 is also possible) 6.Qe2+ Be7 7.dxc5 to trade off the bishops and make it more difficult for Black to regain the pawn.
