Board 3 G/75+5 (delay) B08 Pirc Defense 2 Knights Variation Not having played a single game in 6 weeks, I was reluctant to enter the tournament but there was an odd number of sign-ups. So, at the last-minute, I stepped in. Retirement will wait yet again. 1.e4 g6 The French, Caro-Kann & Sicilian were all considered. 2.d4 Bg7 2...d6 has little independent significance. Play usually transposes to standard orders. 3.Nf3 d6 4.Nc3 Nf6 Now we have a Pirc. 4...a6!? , Tiger's Modern, is the main alternative. 5.h3 This is a dual-purpose move. It stops ...B or Ng4 & prepares Be3. 5.Be2 0-0 6.0-0 is the main line. 5...0-0 6.Be3

6...a6 ! And. Martin 6...d5 , which was 1st played in D. King - McNab : London 1988, ∆7.exd5 or 7.e5 Ne4 8.Nxe4 dxe4 9.Ng5 c5 Roeder - Gutman : Mengen 1990 7...Nxd5 8.Nxd5 Qxd5 was an option. 7.Bd3 7.a4 , restricting Black's planned Q-side expansion, is the typical reply. 7...Nc6 7...b5 B. Sikora Gizynska - Fojcik : Poland 1978, /\ ...Bb7 (putting e4 under pressure) + ... Nbd7 & ...c5. 8.a3 b5 This discourages 0-0-0 but 8...e5 9.d5 Ne7 F. Faco Gome - Montagna : correspondence, Brazil 1993 9.b4!? A big surprise. I expected 9.0-0 Vazquez - Bustelo : Piriapolis 1987 or 9.Qd2 which was tried in Hammond - G. McArthur : correspondence, IECC 2001. 9...Nd7 Previously seen here was 9...Bb7 10.Qd2 e5= 11.d5?! Ne7 12.0-0 c6 13.dxc6 Bxc6 Estela - S. Rodriguez : Cali 2015. 10.Qd2 Bb7 This returns to known practice. I didn't care for 10...e5 11.d5 Nd4 11...Ne7 12.a4 f5 13.Bg5 bxa4 14.0-0 Qe8 15.Rxa4 12.Bxd4 exd4 13.Ne2 but Ne5 14.Nfxd4 f5! 15.exf5 Nxd3+ 16.cxd3 Bxd4 17.Nxd4 Qf6 18.Qc3 Bxf5 yields compensation for the P. 11.Bh6N

11.Ne2 Nb6 12.0-0 e5 13.d5 Ne7 was played in Hughes - Thollin : Gibraltar 2008. 11...Nxd4! Offering the Exchange. ≤11...e5 12.Bxg7 Kxg7 13.d5 Ne7 13...Nd4!? 14.Nxd4 exd4 15.Ne2 c5! 15...Re8?! 16.a4 16.Nxd4?

Time left - Benitez 7:27, Moldovan 10:41 Estimated time used - Benitez 70:33, Moldovan 67:19 Longest thinks: White - 11 minutes for 18.Rfe1? Black - 10 minutes for 29...Rg8 This was my first 1... g6 loss in 34 games, covering 5 years (+28-1-5)! 1–0
