    Notes by Frank Dixon

    1.d4 Nf6 2.c4 e6 3.Nc3 Nc6 4.Bg5!?
    [My opponent here, Dave Gordon, is the older of the two eastern Ontario players with this name, and is a professional artist. David Gordon, the younger and stronger, is an NM in Ottawa. In 40+ years of games with Kingston Dave, I have never seen him open with anything other than 1.d4. He is always a tough opponent, playing strategically in the style of World Champions GM Botvinnik and GM Petrosian. He has been a multiple champion in KCC events, and I think that over the years, I have tried virtually every single sound Black defense to 1.d4 against him! We had a previous game in this variation, which I won, and some buzz and chatter about my Tango line was building around KCC by this juncture. With this move, 4.Bg5, White avoids the challenging 4.e4, as played in our first game, and Black, for best results in my opinion, now needs to send the game more into Nimzo-Indian channels, as I do here with my next move. I did try 4...Be7 against NM Dr. William Doubleday at the Ontario Open, Brantford 2004, and eventually lost a fascinating game, to the veteran competitor, who was born and raised in Kingston, won the first-ever Ontario HS Championship, Kingston 1964, earned his undergrad degree in Math, Queen's class of 1969, and subsequently completed his PhD in Math in the U.K. Bill played in the 1975 Canadian Zonal in Calgary. After retiring as a senior civil servant, he returned to tournament chess after many years absence from it. He then performed some very important governance work for the CFC in the mid-2000s. Bill and I co-wrote the winning bid for the highly successful 2007 Ottawa Canadian Open, when Gordon Ritchie turned into a force of nature in leadership, to help make it one of the very best Opens!!]
    4...Bb4 5.e3 h6 6.Bh4 g5 (6,9) 7.Bg3 Ne4 8.Qc2 f5 (7,13) 9.Bd3 Nxg3 10.hxg3 d5 (11,21) 11.g4! dxc4 12.Bxc4 Qf6 13.gxf5! exf5 14.O-O-O! Bxc3 15.Qxc3 Bd7 16.Ne2 O-O-O (29,32)
    [We are now well away from any previous games or analysis in my praxis with this line, stretching back to the 1970s, through a variety of move orders. With both sides castling long, it is a different strategic setup to virtually anything I had played before. White has an advantage in the center, and I was concerned about his possible pressure down the c-file. I had to remind myself to slow down; playing too fast is a problem I have often battled in longer time controls.]
    17.Ng3 Be8 18.a3 h5 19.Bd3 Ne7! 20.Kb1 h4 (43,52) 21.Rc1! Bc6 22.Ne2 Rd7 23.Rhg1 Rf8
    [I spent significant time looking at 23...Nd5!?, for example 24.Qa5 Kb8 25.e4 fxe4 26.Bxe4 Rhd8 27.f3 +/= b6 28.Qa6 Bb7 29.Qc4 Nf4!? 30.Bxb7 Kxb7 31.Nxf4 Qxf4, =/+, but of course White is by no means obliged to play this line.]
    24.Qa5!? Kb8 25.Nc3 b6 (56,76)
    [Black's draw offer was declined. White has a 20-minute lead on the clock, in a roughly level position, with plenty of play still on the board.]
    26.Qb4 Rfd8 27.Nb5 Bb7 28.f3 Nd5 29.Qd2 c5! 30.Rgd1 a6 (83,85)
    [We reach the first time control, and the game has gotten somewhat sharper; White slowed down his pace of play in response.]
    31.Nc3 Nxe3! 32.Qxe3 cxd4! 33.Qe1 dxc3 34.Rxc3 -/+, 1/2--1/2. (123,98)
    [Black is a pawn up, certainly somewhat better now, and I am now 25 minutes ahead on the clock, but was battling a splitting headache, a frequent problem for me once two hours' play has been reached, as well as (far more importantly) during university exams, often sabotaging my results!! Never really found a solution to it. So, I decided to accept White's draw offer. Many times, I have played on in longer games, then erred and lost, due to errors caused by the headaches. Not this time! Still, a creative success, if not a complete competitive one. In this tournament, my student Raja Panjwani posted a very strong second place; he turned 12 years old as the event wrapped up!]

      Clock times in brackets
      Notes by Frank Dixon

      1.d4 Nf6 2.c4 e6 3.Nc3 Nc6
      [This was game #2 of our training match, not CFC-rated, with nominated openings mutually agreed in advance, colors alternating. Chris had recently moved to Kingston from Toronto, and was very busy with his new job, but was definitely interested in playing some chess. He said he couldn't commit to the Kingston Chess Club's Monday night weekly tournament games, since his busiest days were typically early in the week, and he said he was working 60 to 90 hours per week. Chris did some prep for this game, found some new ideas, and we soon head into uncharted territory!]
      4.d5!?
      [I had faced this a few times, but far less than the lines with the most popular move 4.e4, for example.]
      4...Ne5
      [It remains an open question to me, nearly 25 years later, whether this move is stronger than 4...exd5. More games are needed to decide; I think both moves are playable.]
      5.e4
      [Interesting is 5.Bf4 Ng6 6.Bg3 Bb4 7.f3 O-O 8.Qc2 exd5; I think Black is fine.]
      5...Bb4 6.Bg5!?
      [Fascinating is the very sharp try 6.f4!?, which I have faced a number of times. I've tried 6...Nxe4!? with murky complications! Chris's logical move here, 6.Bg5, was entirely new to me.]
      6...h6 7.Bh4
      [Black seems OK on a line we examined later: 7.Bxf6 Qxf6 8.Qb3 Bc5 9.Qc2 Ng4 10.Nh3 O-O 11.f3 Ne3 12.Qd2 exd5 13.Nxd5 Nxd5 14.cxd5 d6=/+. However, possibly better is 8.e3! Nh5 9.Bd3 Bxg3?! (opening the h-file) 10.hxg3 exd5 11.Nxd5 c6 12.Nf4 Nxf4 13.gxf4 g6, which looks about even. A better line for White now is: 14.Qc3!? O-O? 15.f5 Qe7 16.fxg6 fxg6 17.Bxg6 Bb4, with dangerous chances.]
      7...Ng6 (3,7) 8.Bg3!?
      [Here is one of the ideas he had prepared, a very interesting pawn sac! I decide to accept!]
      8...Nxe4 (4,13) 9.Qd4!? Nxg3 10.hxg3 e5 (9,22)
      [It was very rare for me to trail on the clock so early in the game in this variation!]
      11.Qe3 Qf6 12.a3 Bxc3+ 13.Qxc3 O-O 14.Nf3 d6 =/+ 15.Be2 a5 16.b4 b6 17.O-O Bf5 (16,33)
      [Chris carries on playing at a really brisk pace, but I liked my position, which was very different from anything I had encountered before in the line.]
      18.c5!? Rfc8 19.Nd2 axb4 20.axb4 Ne7 21.Bf3 Qg6 22.Qe3 bxc5 23.bxc5 Rab8 (21,43) 24.Rfc1 Rb4! -/+
      [I believe Black now has a clear advantage. Chris does slow his pace somewhat, with a very long one-move think coming up soon.]
      25.cxd6 cxd6 (31,53) 26.Rxc8+ Bxc8 27.Ra8 Rd4! (37,57)
      [Chris said later he realized he was in some trouble at this juncture. Black is a good pawn up, his pieces are active, and his King is a bit safer. Chris now expends more time, nearly an hour, on his next move than he had previously used in the game!! He actually winds up trailing me on the clock! He is in some time pressure before the first control! He sharpens the game, and is aiming for Queenside infiltration, with some strong potential. But his 29th move is an error, and leaves his own King with little protection.]
      28.g4
      [I think much stronger here is 28.Qc3! Kh7 29.Nc4 Bb7 30.Rd8 Nc8 31.Nxd6!? Nxd6 32.Qc7!? Qb1+! 33.Kh2 Nc4! 34.Qxf7 Qb6 35.Rd7! Qg6 36.Rxb7 Qxf7 37.Rxf7 e4 38.Be2 Ne5 +/=. It is a fascinating position, and this line by no means exhausts the possibilities for either side.]
      28...Qc2! (83,62) 29.Nb3?
      [If 29.Ne4 Nxd5; If 29.Nf1 Nxd5 30.Bxd5 Rxd5 31.Qb6 Kh7 32.Qd8 Be6 33.g5 Rd1 34.Qh8+ Kg6 35.Rg8 Rxf1+! 36.Kh2 {36.Kxf1?? Qd1#} Kxg5 37.Rxg7+ Kh5 38.Qa8 Qxf2 wins.]
      29...Rd3! 30.Qb6 Rxb3 (88,74)
      [Reaching the first time control, and White's game is hanging by a thread.]
      31.Qd8+ Kh7 32.Qxe7
      [White does recover his piece, but Black has a mating attack!]
      32...Qc1+ 33.Kh2 Qf4+ 34.Kh3 Bxg4+!, 0-1. (98,79)
      [A satisfying victory with my variation over a strong player!]
