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.

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.
