CCCR Results for Wednesday September 13 2017

Late result: David Stearns defeated Chris King.

It was a great evening, and a lot of excitement spilling over from Lev Paciorkowski's earlier lecture and presentation, which unfortunately I missed. A number of people who were there all said it was very interesting: Lev went over his games in the recent New York State Championship at Albany.

Those of us who missed Part I still have a chance to see Part II on Wednesday, September 27 at 5:00 pm.

Other announcements: The Rawle Farley Memorial Summer League is winding down and it's time to sign up for the Fall League. There are seven sign-ups so far. Also the CCCR Championship begins October 4.

Today's great chess find is from the Pittsford Central Library

You can do the math but I just like saying it so much: that's only $2.50 for some nice books (one or two are arguable). They're in great shape, too; pretty sure they haven't been read.

Personally, I'm especially looking forward to the Andy Soltis book. I enjoy playing defense almost as much as I like to attack. Of course when you make a lot of errors you have to get used to defending.

SakredKow's first Saturday Tournament at the Rochester Chess Center

I played in my first Saturday Tournament at the Rochester Chess Center ever this past weekend. Although I scored only 1/3 I had a great time and my games weren't too bad.

Randy MacKenzie beat me up pretty good in the first round, but my game against Jamshed Ahmed indicated to me that I should be keeping up with these 1600+-1800+ fighters. Well, time will tell.

As Black, I tried out a variant of the English Defense in both my games against Randy and Jamshed. They both got a better opening against me but nothing too terrible for Black. However, Randy kept the pressure on from start to finish, and I never really got a counterattack going. He beat me handily. You might say I made a number unforced errors.

Jamshed also pressed from the beginning, even netting a pawn advantage early. Still, at a scary point for me I found a nice bishop sac that tipped the game my way. From that position we both made some very good moves, although I maintained a material advantage. My position advantage also seemed strong but it was complicated. Unfortunately I made a serious miscalculation from from there ended up losing.

Yes, it was discouraging. That isn't the only time Jamshed's gotten away from me either, and now my record against him is 0-5.

The overall winner of the Saturday Tournament was Lev Paciorkowski who had a perfect 3-0-0 score with wins against David Stearns, Jamshed, and Randy. Pranav Kumar and Arjun Ganesh both scored two wins with one draw.

English Opening 

6. Bg5         In round one Randy MacKenzie played 6. e3 against me and won pretty easily 6...O-O 7. Nge2 d6 8. O-O Be6 9. Nd5 a5 10. a3 Bc5 11. Rb1 Bf7 12. Bd2 Nxd5 (.pgn format of that game below).

7. e3            7. a3 Bxc3+ 8. bxc3 Qe8 9. Nh3 f4 10. Bxf6 Rxf6 11. Ng5 d6 += Rosenberg-Bachmann Schiavo, PanAm Intercollegiate-chT 2009.

9...a6          This is kind of a clunker. 9...f4 10. exf4 exf4 11. Nxf4 g5 12. Nh3 Bxc3+ 13. bxc3 Qxc3+ 14. Kf1 d6 and White's position looks very difficult, though there could be improvements.

14...e4         I misjudged the security of my queenside, apparently believing it worse than it was I thought sacrificing a pawn would help, but 14...Be6 is fine. (Heh, unless my opinions during the game were right).

19. e4          I'm down a pawn but I thought I was hanging on okay.

22. e5?        A mistake. 22. exd5 cxd5? 23. Bxd5+-. 22...Nd6 23. dxc6 Bxf5 24. gxf5 Nxf5 25. Qc5+-. Both lines should win for White.

22...Bxf5!    The bishop pseudo-sacrifice doesn't just win back material, it sheds Black of the underachieving bishop. I'm reminded of William Shakespeare's Macbeth: "Nothing in his life became him like the leaving it."

31...Rxf8?   The losing move. The (nearly) winning move for Black is any move with the king. I miscalculated however.

Good game for Jamshed.

Lionti-Trowbridge - A draw in the Farley League

Going into round seven of the Farley Memorial League Mike Lionti and I were tied for first place on board three.

As it turned out both of our opponents postponed and we had a make-up from round one to play against one another. We had just played round six against each other the week before and Mike absolutely crushed me. So I was very disappointed not to get a little revenge from this game. It's good to remember that Mike is a very tenacious defender.

The text is incomplete as the final few moves did not get recorded by either of us. I stopped recording moves as soon as I fell to five minutes remaining on my clock, and Mike stopped recording soon after that. In the time scrabble I allowed Mike to capture my a-pawn with his queen, but then he inadvertanly left his a-pawn en prise to my bishop. As I snapped his pawn off I offered him a draw. He played on a few more moves then agreed.

PGN format of the game is at the bottom of this post. 

Farley Memorial League XXVII (Summer) August 21, 2017
WHITE: Jim Trowbridge BLACK: Mike Lionti   G/90 +5sD
French Tarrasch Defense

6....Qg5 Wow! I didn't expect this. 6...Nc6 is the main line, and I have notes showing I looked at 6...b6, 6...Qb6, and 6...b5. 6...Nc6 7. Ndf3 Qb6?! 8. Ne2 cxd4 9. cxd4 Bb4+ 10. Bd2 Qa5 11. O-O += Trowbridge-World, 39th Marchand Op 2017.

7. Qf3 In the past Mike has played 6...Nc6 against me, so I couldn't rule out the possibility he'd actually prepared this variation. I was a little uncomfortable then sacrificing the g-pawn with 7. Ne4 or 7. Ne2. I hated taking the f3 square away from my knight(s) but under the circumstances it seemed like the most logical move to me.

8...Bb4 This seemed pretty strong to me.

10...Qh6 This is dangerous for Black.10...Qd8 is the right move.

11. Nc3 This knight is usually earmarked for f4 in the Tarrasch, so I wondered if I was doing the right thing by sending it over to the queenside for purely tactical reasons (to break the pin on d2).

12. Nb3 I was frustrated being unable to find a direct way to exploit the discovered attack on black's queen. 12. Nc4 f4 13. Nd6 Nc6! and White cannot defend the d4 pawn and his position from here is critical.

13. Bd2 I missed 13. g3 which raises even more uncomfortable questions for Black. The f-pawn is pinned as 13...fxg3 14. Qxf8+ Kxf8 15. Bxh6 gxh6 looks pretty close to winning.

16. Qg4? Black's response, 16...Nxe5! is brilliant. And I never saw it coming.

18. Qe2 18. Kf1 or 18. Kd1 were both extremely scary - I couldn't decide which was least worse. If Black gets to keep his queen on the board the king is going to be very insecure whichever side it leans towards.

18... Qd6? Black should have played 18...Qxe2+ 19. Bxe2 f3 20. Bd1 Nc6 21. Rh3 Ne5 and after 22. Nd4 or 22. a3 Black might still hold.

24. Qf3 Missing 24. Nxc6! Qxc6 25. Qe5 Ra7 26. Qh8+ Kf7 27. Qxh7+ Ke8 28. Qxa7.

25....Qb8 We've both made some bad moves in this game. But Mike finds the moves he needs when he needs them.

27. Qxb7 I looked at 27. Qe5 Qxh1+ 28. Rd1 Qxd1+ 29. Kxd1 thinking that Black had a draw with 29...Rf7. But the computer showed 30. Qg7+ Ke8 31. Bb4! I was already behind on time and I just didn't have the ability to work it all out.

28...Rf7 28...Bxh1? loses to 29. Rg7+ Kh8 30. Rxg6+! e5 31. Bxe5+ and mate next move.

30...Kf8 White's advantages have all disappeared. He's outplayed me.

39. Kc3 From here we both fell into blitz mode as I had less than 5 minutes on my clock. Eventually we settled on the draw. As if the game wasn't dramatic enough for us at this stage I threw away a pawn by letting his king out-triangulate me but he immediately hung his own pawn so no harm was done.

Good advice from the novelist Haruki Murakami

    As I've said, I'm not a very competitive type of person. To a certain extent, I figured it's sometimes hard to avoid losing. Nobody's going to win all the time. On the highway of life you can't always be in the fast lane. Still, I certainly don't want to keep making the same mistakes over and over. Best to learn from my mistakes and put that lesson into practice the next time around. While I still have the ability to do that.

A loss with White vs. the Czech Benoni

Here's a recent Wednesday night CCCR game in which I lost to John-John Lambropoulos. It was the first time we met over the board. Both of us were looking for a quick game so we agreed with TD to Game in 30 mins, and as I recall there was no delay.

I've never played a rated game against the Czech Benoni, but I've played the Benoni proper so I felt comfortable with the opening. I went a little crazy with a counterattack that wasn't quite sufficient however, so...

The PGN format is at the bottom of the post.

 If you want to play along on your engine, copy and paste the PGN format into your text editor (Word, Notebook, etc.) and save it as a text (.txt) file. Using Explorer, find the file in the folder where you saved it, and manually change the .txt extension to .pgn. You may be asked to supply a name for your file as well. Open your chess engine and find the feature that lets you open a new game or file (apart from the database that may be included with your engine). For instance, in Fritz you click the main menu icon which gives you a directory to your computer. Using that dialog box, find the file and click on it, the game should appear in your engines main window. 

Feel free to contact me if you need help.

CCCR Wednesday Trnmt

Benoni Czech      


3. d5 If all other things are equal, I feel like there's no reason why white should not have great winning chances from this position. 4. dxe6 ep fxe6 5. Bg5 Be7 6. Nc3 O-O 7. e3 b6 8. Nf3 Bb7 = Kotov-Casas, Mar del Plata 1957.

6. g3 Nbd7 7. Bg2 a6 8. Nge2 O-O 9. O-O b5 10. cxb5 axb5+- Ivanchuk-Biu Xiangzhi, FIDE World Cup 2011.

7...a6 8. a4 O-O 9. Be3 Ne8 10. Qd2 g6 11. Be2 Ng7 drew in Potkin-Vitiugov, Aeroflot 2009.

9. Qc2 O-O = Garprindashvili-Nishimura, Aosta 1990

9...O-O This position seems slightly in white's favor.

10...a6 11. a4 Bd7 12. O-O Nh5 += Torman-Finegold, Detroit Ch 1992

11. Ne2 White wants to fight for f4.

14. g4 I looked at 14. O-O-O Nhf4 15. Nxf4 exf4 and I didn't like it for white. As I looked at it, I understood that 14. g4 may not have been the best but it was nevertheless irresistible. First, this was a 30-minute game so "correct" and "incorrect" moves have somewhat less importance. Second I figured my opponent wouldn't expect it. Finally, even though I sensed it was not correct, I liked that it was aggressive.

15...Nh4  I overlooked this. While considering 14. g4, I looked at 15...Nf5, and 15...Nf8. 15...Nh4 not so much.

16. O-O-O The open g-file and the h-pawn show some promise for White but in the following play they weren't enough.

17. Rdg1 17. Kb1 might be better. 17...Nxe3 18. fxe3 Bg5 19. Rhf1 Bxe3

18...Bg5 That's the killer right there. The consequences of 14. g4 settle in.

20. Kd1 after the game my opponent asked me why I played this rather than 20. Kb1. And I did look at 20. Kb1 but it seemed to me from there my king was going to die in the queenside corner for sure. So I chose for him to die on Kd1.

22. Rg4 to keep the black queen coming in to h5.

23. Ng3 defending against 24. Re3+ but... A very nice win for John-John.
