An Annotated Game from Pobo and a Tactic from Sebastian

Oghenakpobo Efekoro

I'm starting a bi-weekly assignment of asking kids to annotate one of their own games. Here's last week's very entertaining homework from IS 318's Student Body President, "Pobama" Efekoro:

[Event "Grade Nationals"]
[Date "2009.12.??"]
[White "Kaita Saito, 1544."]
[Black "Pobo Efekoro, 1865."]
[Result "0-1"]
[ECO "B02"]
[Annotator "Pobo Efekoro"]

So it was grade nationals and here is another game that i played. It was the sixth round and i was hot off the last game that i played the day before. I won this game rather easily but it would be nice if we take a look at strategies throughout the game. Lets go!!!!!

1. e4 d5
2. exd5 Nf6
3. Nc3


I was lost here. The opening was out of my knowledge. So let us take a look and see what i was supposed to play. It is apparent that i got myself into a Alehkine position. Gosh i hate that defense. Acccording to chessbase im supposed to play 3....Nxd5 4. Bc4. Wait does this look familiar??? Its a line i just learned!! Black then plays Nb6 and his set up goes Nc6 then Bf5 then g6 followed by Bg7 and 0-0. Black should have a pretty good game after this.

3... Nxd5
4. Nxd5 Qxd5
5. Nf3 Bg4
I thought Bg4 is a great move because it develops a piece with an intention immediately and it also pinned the Knight on f3 to the Queen.
6. Be2 Nc6
7. h3

7. d3 e5 8. h3 Bh5 9. Be3 O-O-O 10. O-O f6 11. c4 Qd7 12. Qa4 a6 13. Nxe5 Nxe5 14. Qxd7+ Rxd7 15. Bxh5 Rxd3 16. Be2 Rd8 17. Rfd1 Be7 18. Rac1 Rhe8 19. Kf1 g6 20. Rxd8+ Rxd8 21. f4 Nd7 {Solic,K (2121)-Leventic,I (2453)/Borovo 2003/EXT 2005/0-1 (46)

7... Bh5
8. O-O

Lord knows whats coming.

8. c3 O-O-O 9. d4 e5 10. O-O exd4 11. cxd4
Nxd4 12. Nxd4 Bxe2 13. Qxe2 Qxd4 14. Be3 Qe5 15. Rac1 Bd6 16. f4 Qe6 17. Rfe1
Rhe8 18. Qf2 a6 19. Bc5 Qf6 20. Rxe8 Rxe8 21. Bxd6 Qxd6 22. Qa7 c6 {
Scholze,R (2050)-Harzer,P (2125)/Dresden 2006/CBM 111 ext/0-1 (54)}

8... e6


9. d4
9. c4 Qd7 10. Qb3 Rb8 11. Re1 Bc5 12. Qc3 O-O 13. Ne5 Nxe5 14.
Qxe5 Bxe2 15. Qxc5 b6 16. Qb4 Qd3 17. b3 Rfd8 18. Bb2 Qxd2 19. Qxd2 Rxd2 20.
Be5 Rc8 21. Kh2 Bh5 22. f3 Bxf3 23. Rg1 f6 {Dethlefsen,O-Wisnewski,C/Germany 1993/EXT 2002/0-1}

9. b3 Bd6 10. c4 Qe4
11. Bb2 Bxf3 12. Bxf3 Qf4 13. Re1 Qh2+ 14. Kf1 O-O 15. Qc2 e5 16. Bxc6 bxc6 17.
c5 Be7 18. Bxe5 Qh1+ 19. Ke2 Qxg2 20. Rg1 Qxg1 21. Rxg1 f6 22. Bxc7 Rfe8 23.
Kd1 Bd8 {Lafortune,G-Tardits,A/St Chely d'Aubrac 2002/CBM 089 ext/1-0}

9...O-O-O

This is typical me. I castle on opposite sides and play for the attack. Right now in the position everything is going right for black. All pieces are developed or can be easily developed. Black also has pressure on d4. Whites pieces look very passive. All of his pieces are not really active. He can easily develop his pieces but his postion just lokks clumped up.
10. c3

I think that he is losing now after this because he wasted two tempos on pawn moves in the last 5 moves or so. According to Mr. Sher i would be up a pawn now.

10...f6

Everybody obviously knows my intentions. I intend on attacking my opponent to death. This is typical Pobo.

11. Be3 Finally!!!! g5 The attack is slowly forming.

12. Nd2?
This move is a very passive move. I give this move a question mark becauseit just gives me an extra tempo because of Bxe2 then Qxe2 then h5.

12... Bxe2
13. Qxe2 h5
14. Qf3
I thought this was a very good move by opponent. He wants to force me to trade queens or else i lose the pawn on f6.

14... Qd7


This is a powermove because i essentially told him take it and watch what happens.

15. Qxf6 And he took it.

15...Be7

Im down a pawn but up two tempos on my opponent.

16. Qf3 g4

This is the best move of the game played by me. It opens the position on the king side and attacks the queen at the same time.

17. hxg4 hxg4
18. Qxg4


My opponent was a very greedy person.

18... Rh4

One more tempo! Rh4 is a powerful move because it doubles up the rooks in a hurry wasting no time.

19. Qe2 Rdh8

Another tempo!! The best move for white her was to play f3. Black responds with Rh1 check and white has the escape square f2. The white king runs to f2 where the king is safe.

20. g3 Rh1+
21. Kg2 Qd5+

He resigned. His greediness is what got him into this mess. 0-1

a cute tactic from Sebastian

Sebastian was black in the above position today against Eriberto Guzman. White just played 23. Bd6, skewering the queen and rook. Black to move. ...

another picture of Pobo to cover the answer

23. Bd6! Qxd6 24. Rxd6 Rxc1+ 25. Bd1...



25... Bc2! (25...Rfc8!! -/+) 26. Qxc2 Rxc2 27. Bxc2 Rc8 28. Rd2 Kf8 29. f3 Ke7 30. Kf2 Nd5 31. e4 Nb4 32. Bb3 Rc1 33. Kg3 Nc6 34. f4 Re1 35. e5 Re3+ 36. Kg4 Rxb3 *
