Michigan M/X and Class Championship Day 2

After getting to bed at about 1 a.m. Sunday morning, and waking up at 8, I was very tired.

In my fourth game, I was playing Kenneth Tack. This man had only played in 2 tournaments before, and only had a rating of about 1475. Ken was a very strong player though, and beat me in an interesting Knight and pawn engame using a nice forking tactic either winning my knight or promoting his pawn. Unfortunately, I don't have the game because I left it at our hotel... After the game, we went over it and saw where I went wrong. About Ken, he ended up in a 3 way tie for first in our "C" Section, and boosted his rating to 1700! Congradulations Ken, and thank you for a good game!

In the final round, I was white playing against a girl from ann arbor named Joy Chen. This girl was 11, just like me. It was very fun to play against a person my age and skill level. In this game, I got very lucky, and got a great attack right after the opening that she was unable to stop, unfortunately.

Joshua Posthuma (1517) vs. Joy Chen (1475)

1.d4 Nf6 2.c4 g6 3.Nc3 Bb7 So Joy is a King's Indian player... 4.e4 d6 5.Nf3 0-0 6.h3 King's indian Makagonov. 6. ...Re8 7.Bd3 e6? Immediately when she picked up her E pawn, I thought she was playing e5, which makes more sense. This move is still fine if she plans on fianchettoing her light bishop. 8.Be3 Nc6 9.0-0 Bd7!? 10.Qd2 Rf8? She wasted a move moving the rook from f8 to e8, and then back to f8 again. What is her goal with this move? f5 is what I see. 11.Bh6 Ne8 12.Bxg7 Nxg7? This is a defensive mistake. This allows a good move on my part. Better would be Kxg7, defending the h6 square. 13.Qh6! This threatens Ng5 the next move and h7 cannot be guarded, and that would end in mate. She chooses the only defense. 13. ...Nh5 14.Ng5 Nf6 15.f4 preparing e5. 15. ...Re8. hehe and back to e8 it goes! =D This prevents checkmate on h7 after the knight is taken. 16.e5 breaking through... 16. ...Nxd4 Grabbing a pawn while he waits for white's next move. 17.exf6 Qxf6 18.Qxh7+ Kf8 19.Nce4 Bringing yet another piece into the attack! 19. ...Qg7 Black's bes move. I came to a big decision now. It would help me alot to just trade queens and try to win the game up a knight for a pawn, but I didn't know if I could continue the attack with Qh4, and try to still pull something out of it. I didn't want to pass an opportunity to trade queens, but I also wanted to go through with the attack, which I couldn't do without my queen. In the end, I decided to try to continue the attack, and to see if his queen was enough defense or not. 20.Qh4! Nf5 Black attacks my queen, trying to fight it back to the second rank and stop my attack. Luckily, I had seen how to come through with the attack after Nf5, and still win with my queen still on h4. My two knights proved very helpful in launching this attack. 21.Nh7+ Kg8 22.Nef6+ Kh8 23.Bxf5 exf5 And now, with a discovery lined up on the H file, I can finish it off.
White to move and mate in 2.
24.Ng5+ (Nf8+) 24. ...Qh6 25.Qxh6#
1-0

So overall, the tournament went very well for me. I got a total of 3.5/5, and boosted my rating up to 1571. 29 small points to B class!

Also, congradulations to Andrew Schremser from our Holland Chess Club who played in the E class championships, and tied for first with Rachael Tao. They both got 4/5. Andrew got $120 and a large trophy. Good job!

So that is how my tournament went at the Michigan Master Expert and Class Championship. Bye for right now!

Michigan M/X and Class Championship Day 1

In the first day, I played 3 rounds of chess. We woke up at 5:00 in the morning and left from Holland, MI to Lansing at shortly after 6:00. : (  We arrived shortly after 8:00, and checked in.

In the first round, I (1517) was playing a man named Dan Holt (1405) as white. I had played Dan before at the Saint Joseph chess club. This game was very tough, and I questioned whether I could pull out even a draw. In the engame I messed up, and offered a draw, and of course he declined. Unbelievably, I was able to take advantage of a big mistake later, and ended up winning by 1 tempo. : ). Here is the game below:

Joshua Posthuma (1517) vs. Dan Holt (1405)

1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Nf3 Nbd7 5.e3 Be7 This is a common queen's gambit line called the Orthodox. 6.Bd3 0-0 7.Qc2 b6 8.a3 Bb7 9.cxd5 exd5 10.Bd2 Rc8 11.0-0 Bd6? 12.Nb5! This is a good move attacking both d6 and a7. 12. ...a6 13.Nxd6 cxd6 The good thing about this trade for white is that it gives black two doubled isolated pawns, and white has a bishop vs. knight. 14.Qb3 Ne4 15.Rac1 b5 16.Rxc8 Qxc8 17.Ba5 Qc6 18.Qc2 Rc8 19.Rc1 Qxc2 20.Rxc2 Nb8 21.Rxc8+ Bxc8 22.Kf1 Nc6 23.Be1 Bg4 24.Nd2 Bf5 25.Ke2 g6 26.f3 Nxd2 27.Kxd2 Be6 (27.Bxf5? Nxf3! 28.gxf3 gxf5) 28.Kc2 Kf8 29.a4 bxa4 30.Bxa6 Bd7 31.b4 axb3 32.Kxb3 Ke7 33.Bg3 Na5+ 34.Kb4 Nc6+ 35.Kc3 f5 36.Bh4+ Ke6 37.Bb5 Na5 38.Bxd7 Kxd7 39.Kb4 Ne4 40.Bg5 Ke6 41.Kb5 Kd7 42.e4 Na3+ 43.Ka4 Nc2 44.exd5 Ne1 45.b4 Nxg2 46.f4 Nh4 47.Be3 Nf3 48.h3 h6 49.Kb4 g5 50.fxg5 hxg5 51.Kc3 f4 52.Bf2 Nh4 This was a very big mistake by my opponent, probably a blunder. This allows me to trade and win the f4 pawn, bringing me into a winning game. 53.Bxh4 gxh4 54.Kd3 Ke7 55.Ke4 Kf6 56.Kxf4 Kg6 57.Kg4 Kf6 58.Kxh4 And now I'm in a won game. The funny thing is, just about 20 moves earlier, I had offered a draw which he declined. Little did I know I would go on to win the game. 58. ...Kf5 59.Kh5 Ke4 60.Kg5 Kxd5 61.h4 Kxd4 62.h5 Ke5 63.h6 d5 64.h7 d4 65.h8=Q Ke4 66.Qh1+ Ke3 67.Qd1 d3 68.Kg4 Kd4 69.Kf3 Kc3 70.Ke3 And black resigned.
1-0

In the second round, I was playing my friend Bill Ignasiak on the white side of A king's indian. The game ended in a draw by three move repetition.

Joshua Posthuma (1517) vs. Bill Ignasiak (1556)

1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 0-0 6.h3 c6 7.Bd3 Qc7 8.Be3 h6 An interesting move my opponent commonly plays to keep white's bishop out of h6. 9.Qc1 Kh7 10.0-0 Nbd7 11.Re1 e5 12.d5 a6 13.Qd2 c5 14.Rac1 Nb6 15.Red1 Bd7 16.Nc1 Nc8 17.f4 I was trying for a breakthrough of some sort. 17. ...exf4 18.Bxf4 Ne7 19.Nf3 Ne8 20.Re1 f6 21.Kh1 Nc8 22.Re3 Kh8 23.Rf7 g5 24.Bh2 Qd8 25.Ree1 Qe7 26.Qc2 Rd8 27.Na4 Bc8 28.Nb6 Qc7 29.Nxc8 Qxc8 30.a3 Qd7 31.Qd1 Rf7 32.Nd2 Bf8 33.Be2 Rg7 34.Bg4 Qe7 35.b3 a5 36.Nb1 Nc7 37.Nc3 b6 38.a4 Now for the three move repetition. 38. ...Qe8 39.Bh5 Qe7 40.Bg4 Qe8 41.Bh5 Draw agreed.

In the third round, I was playing a man named Daniel harper. This game was very good, and even all the way through, but my opponent got into severe time pressure when I still had about 45 minutes! With that time advantage, I was able to pull out a win.

Daniel Harper (1555) vs. Joshua Posthuma (1517)

1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 Making the game a Nimzo-Indian. 4.e3 0-0 5.Bd3 d5 Transforming into a queen's gambit declined orthodox.  The only difference is the Bb4. 6.Nf3 c5 7.0-0 Nc6 8.a3 Bxc3 9.bxc3 cxd4 10.cxd4 Bd7 11.Bd2 Rc8 12.cxd5 exd5 13.Qb1 b6 14.Rc1 Re8 15.a4 h6 Allowing my knight to move away. 16.Re1?! Ne4 17.Ra2 Nxd2 18.Nxd2 Qf6 19.Rc2 g6!? 20.Rec1 Na5 21.Rc7 Rxc7 22.Rxc7 Bxa4 23.Rxa7 Qd6 24.h3 Rc8 25.g3 Bd7 26.Kg2 Kg7 27.Nf3 Rc7 28.Rxc7 Qxc7 29.Ne5 Be8 30.f4 Nc4 31.Qe1 Nxe5 32.fxe5 Bc6 33.Qf1 Qe7 34.h4 Qe6. Right now my opponent has 9 minutes and I have 47. 35.Qf3 Bb7 36.h5 Bc8 I have just been wasting my opponent's time while thinking of a plan by making waste moves. 37.hxg6 fxg6 38.Kg1 Bd7 39.Qf4 Bc8 40.Qf3 Bd7 41.Qf4 b5 Starting my plan. This will make him think even longer. 42.Qf1 Qb6 43.Qf4 b4 44.Qh4 Qe6 45.Qd8 Be8 46.Qc7+ Bf7 47.Qc5 Qh3 Storming in white's position. 48.Kf2 Qh2+ 49.Kf3 This is possibly dangerous... locking the king in the center. It is a way to save the pawn, though. 49. ...Qh1+ 50.Kf4? A big blunder.                                    Black to move and mate in 3.
50. ...g5+ 51.Kg4 Qh5+ 52.Kf5 Qf3#
0-1

And so, that wraps up the first day of the tournament. I started off 2.5/3.0.... Not to bad! Look forward to the last 2 games tomorrow.

Michigan Master Expert and Class Championship

I has been a long time since I have posted, but I felt like sharing that I will be playing in the Michigan M/X and Class tournament in lansing. Since my rating has climbed to the 1500's I will be playing in the top of the "C" section. If any of you are going to be playing, please inform me in the comments. Also, look forward to atleast one of my games from that tournament being posted on the site also.
