2007 Alberta Open 2007-Oct

This 3 day event was held over the Thanksgiving weekend and had 50 participants. I yo-yo’d back and forth losing against higher rated opponent and then beating lower rated ones.

Round 1 was against Dale Hassel (2262). I completely mis-evaluated the opening and was crushed. After the game Dale explained that my whole plan to push f5 was faulty but at the time I had no other plan. 12...f5? [¹12...c6!?±] 13.dxe5+- dxe5 14.Rad1 Qf6 15.c5 Nd7 16.Nd5 Qd8 17.exf5 gxf5 18.Nh4 Nb8 19.Nb6 Qe8 20.Nxa8 then resigned on move 35 1–0

Round 2 was against Keith Aartsen (1447). Position after 7…h6?? I played 8. Bxf7! Kxf7 9. Ne5+! Ke8 10. Nxg4 and won the game after 32 moves.

Round 3 was against Micah Hughey (2113). He played some kind of pseudo-Marshall and used no time on his clock where as I used plenty of time in the opening. I saw a tactic for myself and couldn’t find a refutation at the board so I played it. 12.Bxf7+ Kxf7 13.Rf5+ Bf6 14.Rxf4 Qd3 15.Rf3 Bxf3 16.Qxf3 Qxf3 17.gxf3 Obviously he played this variation many times before and when he played the clamping Qd3 I new I was in big trouble. I sacked the exchange to try to free myself but it was too late. I lost after 47 moves when he sacked the exchange back and we would both queen but he would win my queen with a skewer check.

Round 4 was against young Jonathan Mrugala (1680). He played 30.Qh3+ which allowed me to play 30...Qh5+³ and then exchange off the queens 31.Qxh5+ Kxh5 and enter a minor piece ending. At this point we both believed we had the better position. 32.Bh3 Ne7 33.Kf3 Kg5 34.Kg3 h5 35.Be6 Ng6 36.h3 Nf4 37.Bc4 37...Ne2+ [¹37...h4+!? 38.Kh2 Kf6µ] 38.Kf2= Nc1 39.Be6?? I was too aggressive with my knight and if he had played [¹39.b4 cxb4 40.Ke1± I would have been in trouble] 39...Na2³ 40.Ke2 Kf4 41.Bf7 h4 42.Kd2 Nb4 43.c3? Nc6–+ 44.Be6 Ne7 45.b4 Kg3 46.Bd7? Ng6 47.bxc5³ bxc5 48.cxd4?? [¹48.b4 the only rescuing move 48...dxc3+ 49.Kxc3 cxb4+ 50.Kxb4µ] 48...cxd4–+ 49.Kc2 Nf4 50.b4 Nxh3 51.Kb3 Nf2 52.Kc4 Ng4 and I mated him on move 72. 0–1






Round 5 was against Vlad Rekhson (2175). The position shown was reached after exchanging queens on e4 with 26.Bc8 Qxe3 27.fxe3 Another knight vs bishop endgame but this one I mishandled and allowed him to get an outside passed pawn 27...Nd8 28.Kf2 a5 29.Kf3 b6 30.Ke4 Kf7 31.b4 axb4 32.cxb4 Nc6 33.c3 h5 [33...d5+ 34.Kd3=] 34.a4 h4? [34...d5+!? 35.Kd3 Ne5+ 36.Ke2 Nc4²] 35.Bb7± Ne7?? [35...Nd8 36.Ba8 Ke6+-] 36.a5+- f5+ 37.Kd4 c5+ 38.Kd3 bxa5 39.bxa5 Ng6 40.Kc4 Ke7 41.a6 1–0

Round 6 was against Mike Sekuloff (1614). I played the opening badly and once again he was looking to sacrifice but he missed his chance when he played 11...Be6 [instead of ¹11...Bxh3!? 12.Be3 Bg4µ] 12.Bg5 Bc7 [still 12...Bxh3 13.gxh3 Qg3+ 14.Kh1 Qxh3+ 15.Nh2=] 13.Qd2 Nd7 14.Bh4 Nde5? [¹14...Qf4!?² would keep Black in the game] 15.Nxe5+- Nxe5 16.Bg3 f6± 17.Nd4 Rae8 18.Nb5 Qd7 19.Nxc7 Qxc7 20.Qf4 g5? [¹20...Qc5= and Black is still in the game] 21.Qe3 Qd7 22.Bxe5 fxe5? 23.Qxg5++- Qg7 24.Qxg7+ Kxg7 25.Rxe5 1–0

Overall every game went as expected by ratings. I finished at 3/6 which was good enough for shared first in under 1800 with Vitaly Motuz and Allen Wu. Rp=1883 and brought my rating up to 1809.

Edmonton International (Sectional) 2007-Aug

After experiencing the yo-yo effect during my first tournament I was hoping that this sectional, run in conjunction with the Edmonton International, would give me a better indication of my current playing strength. Round 1 was Friday evening and after achieving a good position a clear pawn up, and my opponent having double isolated c pawns, I missed my chance to maintain my extra pawn on e4 with 13…f5. Then I reached the following position after 18.Bc7=.

18...Bd5 [18...Rd7 19.Rxe6 Rxc7 20.Qh3=] 19.Bxd8² Bxe4?? [¹19...Rxd8 would save the game 20.Qd1 f5±] 20.Qxe4+- Rxd8 [20...Qd2 there is nothing better in the position 21.Bc7 Kh8+-] 21.Qe6+ This is the check that I missed in my analysis at the board when I took on e5 with the bishop Kf8 22.Qe7+ Kg8 23.Qxd8+ Kf7 24.Qe8# 1–0

Round 2 I played a teenager (who are almost always underrated) and achieved the following position. At the time I was sure was it was a winning position but after placing my king in a bad position I was the one forcing the draw.

42.c5 h5 43.Kc4 h4 44.c6 Rc8 45.Kd5 h3 46.Rb7+³ Ke8?? Black is ruining his position [¹46...Kf6 and Black can hope to survive 47.Rh7 f4 48.Rxh3 g5=] 47.Rh7± h2 48.Rxh2 Kf7 49.Kd6 Rd8+ 50.Kc7 Rd3 51.Kb7 Rb3+= 52.Kc8 Kf6 53.c7 Rc3 54.Kd7 Rd3+± 55.Kc6 Rc3+ 56.Kb6 Rb3+² [56...Rb3+ 57.Ka5 Rc3±] ½–½

So after 2 rounds I had a disappointing 0.5/2 points. Round 3 I played a decent game against Trevor from Saskatchewan and my 2 connected passed pawns were decisive.

For round 4 I asked my opponent if he wanted to play Saturday evening since the club was open for the grandmaster tournament anyway. He graciously agreed and that was supposed to allow me to start home earlier on Sunday but I ended up having to take the family to the West Edmonton Mall amusement park Sunday afternoon anyway. This is my favorite tournament game I’ve played. I just love the white pawn storm – in fact 11 of my first 17 moves were pawn moves. I thought I played a great game but of course Fritz found many improvements. This brought me to 2.5/4 and into contention.

[¹32...Rh2= would keep Black alive] 33.Rh1+- Kg8 34.Be8 Rd8 35.Bxc6 bxc6 36.Ne7+ Kf8 37.Nxc6 Rd7 38.Rh8+ Kf7 39.Rh7+ Ke6 40.Rxd7 Kxd7 41.Nxa7 Ke6 42.c4 Kd7 43.Kc2 Bg5 44.Kb3 Bd2 45.Nb5 Kc6 46.Nc3 Be1 47.Nd5 Ba5 48.Ka4 Bd2 49.a3 Be1 50.b4 cxb4 51.axb4 Bf2 52.Ka5 Bh4 53.Ka6 Bf2 54.b5+ Kd7 55.b6 Kc6 56.b7 1–0

My final round was Sunday morning against Mike Sekuloff and Mike was in the mood to sacrifice. I believe he missed the Bishop retreat 11 …Be6 and later on 19 …Ne4.

I finished at 3.5/5 which I found out later was good enough for shared first with Jason and Allen. Rp=1863 and brought my rating up to 1795.
