1 e4 e6 2 d3 d5 3 Nd2 Nf6 4 Ngf3 c5 5 g3 Nc6 6 Bg2 Be7 7 O-O O-O 8 e5 Nd7 9 Re1 b5 10 Nf1 a5 11 a3 (This move can not be recommended.  This is a line where White's main goal is to out-attack Black.  White goes full force for the Kingside while Black goes for the Queenside.  With this pawn advance, he's speeding up Black's play.  Rounds 5 and 9 both saw the same opening, and with White avoiding a3 in both games, White went on to win both times.) 11...Ba6 12 h4 b4 13 ab4 ab4 14 N1h2 Qc7 15 Bf4 Bb5 16 Qe2 Ra5 (Black intends to double up on the a-file.  White is now forced to surrender his contesting of the a-file.  Black should have at least a small advantage here, if not better.) 17 Ra5 Qa5 18 Bh3 c4 19 dc4 Bc4 20 Qd1 Nc5 21 b3 Bb5 22 Bg5 Ne4 23 Be7 Ne7 24 Ng5 Ng5 25 hg5 Qc7 26 Qd4 Qc3 (26...Qc2? 27 Qb4 and White wins a piece.)  27 Qc3 bc3 28 Ra1 Nc6 29 Nf3? (This is the wrong way to defend the e-pawn.  White should have played 29 f4) 29...Be2 30 Kg2 Bf3 31 Kf3 Nd4! (This is better than 31...Ne5 as the latter move allows White to play more actively with his King.) 32 Kg2 (White's King must return to the g-file as 32 Kf4 fails to 32...Nc2 and if 33 Rc1, then 33...Nd4 prevents White from taking the pawn due to a fork on e2.) 32...Rc8 33 Rc1 Ra8 34 Bg4 Ra2 35 Bd1 (White's pieces are in an awful bind having to defend the c-pawn.  White's only hope is to get the King across to attempt to break up that bind.) 35...Kf8 36 Kh3 Nc6!! (Forcing White to do what he doesn't want to do) 37 f4 (A sad necessity.  The White King can never go on the 2nd rank again due to the threat of ...Nb3, either winning the rook, or else promoting the pawn after a rook trade on b2.  At this point, with the knight on d4 covering f3 and f5, and the 2nd rank cut off from the White King, all Black has to do is prevent White from ever having the f4 square available to his king to get at the Black Knight.) 37...Nd4 38 g4 Ke7 39 Kg3 f6! (This move is necessary so that if White ever plays f5, Black can respond with ...e5 without having to allow an en passant.  Black will even allow White a passed f-pawn at the cost of never having the f4 square available to the White King.) 40 gf6 gf6 41 ef6 Kf6 42 g5 Kg6 (42...Kf5 allows the tempo-gaining 43 Bg4 and the King would be forced to retreat as 43...Ke4?? drops the knight to 44 Re1.) 43 Kh4 Kf5 (43...Nf5 followed by Ne3 and winning the c-pawn probably works also.) 44 Kg3 Ke4 45 Bg4 Rc2 46 Rc2 (Trading probably makes it even easier for Black, but White was dead anyway.) 46...Nc2 47 Be6 Ne3 48 Bg8 c2 49 Bh7 Nf5 50 Kg4 c1=Q 51 Bf5 Ke3 52 Bh7 Qd1 0-1 (Notes by McCartney)
