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.

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.
