{axiom vs likesforests}

1. e4 d5 2. f3

{Opening: Scandinavian-Possum. The Possum is an opening some Australians are experimenting with.}

dxe4 3. fxe4 e5 4. Nf3 Bc5 5. Bc4 Nf6 6. Nc3 a6 7. h3 0-0 8. g4 Nc6 9. d3 Na5 10. Bb3 Nxb3 11. axb3

{I feel my position is very solid. My opponent can't castle, they have doubled pawns, and I have the bishop pair. But how to proceed? A queen-side pawn advance would undouble his pawns, while a kingside pawn advance would weaken my king. I don't see any immediate way to attack his king while it's stuck in the center. I'm looking for something more specific than "open the position" -- doh. :) }

c6 12. Qe2 Re8 13. Nd1 b5 14. Ne3 h6 15. g5 hxg5 16. Nxg5 Nh7 17. Nxh7 Qh4+ 18. Kd1 Qxh7

{I had been waiting for 15.g5 and had the whole tactical response planned out. I still have the bishop pair, he still has doubled pawns, and two files are half-open with his king in the center, but I can't come up with any plan to take advantage of these pluses.}

19. Qg2 Be7

{Probably a mistake... I cede a good diagonal to my opponent.}

20. Ng4 f6 21. Be3 Kf8 22. Kd2 Be6 23. Raf1

{Now his pieces seem better placed than mine, and I'm wary of his potential attacks.}

Bd6

{ Oops. Rybka says we both missed a 12-move tactical sequence. ;-) }

24. d4 exd4 25. Bxd4 Bxg4

{I give up the bishop pair to reduce the pressure on my f-pawn. Calculating the long tactical sequences is giving me a headache, and I'm bound to miss one.}

26. hxg4 Qg6 27.Rf5

{We adjourned for 6 months. When I returned, I noticed my opponent's pieces are better placed and so decided to trade down to an endgame, aiming for a draw}

Be5 28.Bxe5 Rad8+ 29.Kc1 Rxe5 30. Rxe5 fxe5

{The sequence went exactly as expected! I'm one step closer to a draw.}

31.Qf2+ Ke7 32.Qc5+ Qd6 33.Qa7+ Rd7 34.Qxa6

{I've mostly been trying to block my king from checks. I'm a pawn down, but now I see an opportunity to trade away our rooks. And a queen endgame, one pawn down, is usually a draw.}

Qd2+ 35.Kb1 Qg2 36.Re1 Qxg4 37.Qxc6 Rd1+ 38.Rxd1 Qxd1+ 39.Ka2

{We're down to K+Q+3P vs K+Q+2P, after the exchange sequence went mostly as expected.}

b4

{Perhaps Qd8 was better. I was hoping for perpetual checks, moving my queen along the e1-a5 diagonal. I think I made this move too hastily.}

40.Qc5+ Kf7 41.Qc4+ Kg6 42.c3

{Qxb4 was probably better for my opponent--our errors canceled out.}

bxc3 43.bxc3 Kh5 44.Qf7+ g6 45.Qh7+ Kg5 46.Qe7+ Kf4 47.Qf7+ Kxe4 48.Qxg6+ Kf4

{Further simplification.}

49.Qh6+ Kg4 50.Qe3 Kf5 51.b4 e4 52.Kb2 Qf3

{1/2-1/2. He played the last few more moves hoping I would goof up, and seeing I didn't, agreed to the draw.}

You might want to put this in PGN so it's easier to play through.


1. e4 d5 2. f3

{Opening: Scandinavian-Possum. The Possum is an opening some Australians are experimenting with.}

It's crap.


2... dxe4

No need to hurry with this exchange. Why not play ... e5, Nf6, Bc5 and leave the pawn looking silly on f3?


3. fxe4 e5 4. Nf3 Bc5 5. Bc4 Nf6 6. Nc3 a6 7. h3 0-0 8. g4 Nc6 9. d3 Na5 10. Bb3 Nxb3 11. axb3

{I feel my position is very solid. My opponent can't castle, they have doubled pawns, and I have the bishop pair. But how to proceed? A queen-side pawn advance would undouble his pawns,

Don't worry about that. They are not weak in this position per se. But they can be a disadvantage in allowing the opponent to make a pawn break that happens to undouble them, e.g. with an eventual a4. Compare my game with Cashman (post #38) (http://www.chesschat.org/showthread.php?t=5897&page=3&highlight=cashman), 33. b4 undoubling the c-pawns.

I agree with Jono assesment of the opning;)

b-double pawns are not relevant - they are part of compact mass and is not a weakness

Instead of 9...Na5 I'd consider 9...Ng4 10.hg4 Bg4, as 11...Nd4 is difficult to parry. It requires, of cource, careful calculation, but seems strong at the first glance.

A more cautios plan after the knight for bishop exchange is to try and move your knight to g6 and then either f4 or h4.
Something like g5 should generally be met with f5, opening the f file against "centralised" king

its ok, jono and igor, nigel short himself called this opening "a sack of manure"(yes, a direct quote,but dont ask me to reproduce it! ;))
and herein lies its power!.........it is simply nowhere near as bad ,as some would like to pre-suppose.
when i pressed nigel on why this opening was so poor, he could only muster the weak g1-a7 diagonal, but i have achieved many good positions by blocking this diagonal with Qe2 and Be3 or sometimes Nh3->f2.
..having played igor in this line already ,i lay down the possum-lined guantlet to jono,being happy to play an instructional game in this line.

In the game of Go, there is a proverb, "Beware of going back to patch up your plays." This is supposed to warn against over-extending oneself and having to lose tempi repairing the defects. In this line, f3 has positive point, yet you are forced to cover your weaknesses (if you can) before the plans you would like to make yourself.
