{"Being initially seeded in dead center middle of the pack, making it to the
final round of an open tournament like this on one of the top boards I thought
would be nothing less than a pipedream. Yet, here I am up against a former
Canadian Champion who played in three Olympiads." - SM} 1. c4 e6 2. Nc3 f5 {
"A move order that gives White plenty of flexibility. He can play quietly as I
did, but can also chose more aggressive systems with e4, or h3 and g4 etc. to
try and immediately undermine the Dutch pawn formation, something the Ginger
GM would approve of in a must-win situation!" - SM} 3. d4 Nf6 4. Nf3 Bb4 5. Qc2

the slightly more exposed position of the Q there:} c5 $5 (5... a5 $5 6. a3 a4

WIlliams -- the "Ginger GM" -- in his book "The Killer Dutch".}) 5... O-O {
White actually scores badly from this position: 37%, but only Elo -20, which
means it is most often reached in games with a much higher-rated Black.} 6. Bg5

weakened, but Black has only two pieces which can get there quickly. The GM
playing Black thought that wouldn't be enough so he finished developing.} d6 $2

nothing after ...Rg6.}) 14... Rh6 (14... d6 15. Rg1 $13) 15. Qe5 Qh5 {Black
