Schools of thought

What are the different schools of thought in chess and what do you believe is the most effective against a flawless leveled PC computer?

What is the meaning of "flawless levelled"?

Do you mean a program which tries to play on a certain Elo level, like i.e. 2000? I think such Elo settings are never flawless... only rough estimations. Also, the profile of an engine at strength x Elo will always be much different to a typical human with strength x Elo... Disregarding that we do not even have sufficient data for such comp to human Elo comparisons or calibrations (especially nothing up-to-date).

(But maybe you mean something else.)

Anyway, the basical guideline for playing against comps is that they are tactical monsters.

What are the different schools of thought in chess

You should always attack like pirates over the wall (just ask Tal).
Unless you should focus on positional ideas (just ask Nimzowitsch).
Or should we try to develop or close the position or open it or???

I guess you are talking about anticomputer chess. Closed positions can be helpful, as can trick openings like Stonewall, but even these ideas are far less effective than they used to be a few years ago.

and what do you believe is the most effective against a flawless leveled PC computer?

I can't parse this sentence, but maybe you want this:

David Levy has a great quote from the days when he would play against computer programs and slay them. When asked what his game plan was he said something like:

"I will do nothing, but do it well."

By this he means, avoid tactics as much as possible, and play for a strategically-oriented game that you are comfortable with.

I had a "friendly wager" about being able to beat a very strong, top-of-the line program at correspondence time controls of move-per-3-days. I had white and I played 1. b3 and eventually won.

I will spare the name of the engine but trust me, it's been at/near the top 10 of the ratings lists for a long time (when this game was started, about a year ago.)

The game:

[Event "Friendly moneyless wager, correspondence time controls"]
[Date "2006.10.24"]
[White "Ed Trice"]
[Black "Very Strong Program"]
[Result "1-0"]

I've only been able to do this on one other occasion...with a different opening against a different program:

1. Nf3 Nf6 2. c4 e6 3. d4 d5 4. cxd5 exd5 5. Nc3 c6 6. Bg5 Be7 7. Qc2 g6 8. e3 Bf5 9. Bd3 Bxd3 10. Qxd3 O-O 11. O-O Nbd7 12. Bf4 Re8 13. h3 Bf8 14. Qd1 h6 15. Rc1 Rc8 16. Qc2 Bg7 17. Rfd1 Qe7 18. Qb3 Nb6 19. Nd2 Nh5 20. Bh2 Bf8 21. Nf3 Ng7 22. Ne5 Kh7 23. Qc2 Ne6 24. Nd3 Kg8 25. Na4 Nc4 26. Nac5 b6 27. Nxe6 Qxe6 28. Qe2 Nd6 29. Rd2 Ne4 30. Rdc2 c5 31. dxc5 bxc5 32. f3 Ng5 33. Nxc5 Qxe3+ 34. Qxe3 Rxe3 35. Bf4 Re7 36. Bd6 Re3 37. Bxf8 Rxf8 38. Rd1 Rd8 39. Rcd2 Ne6 40. Rxd5 Rxd5 41. Rxd5 Nxc5 42. Rxc5 Re2 43. Rb5 a6 44. Rb6 a5 45. a4 Kg7 46. b3 Rb2 47. Kh2 h5 48. h4 Rd2 49. Rb5 Rd3 50. Kh3 Kf6 51. Kg3 Ke6 52. Kf4 Kf6 53. Ke4 Rd2 54. Rxa5 Rxg2 55. b4 Re2+ 56. Kd5 Rd2+ 57. Kc6 Rh2 58. b5 Rxh4 59. b6 Rb4 60. b7 h4 61. Rb5 Rc4+ 62. Kd5 Rxa4 63. b8=Q 1-0

That game was an exploitation of a common Rook-and-Pawn ending that many engines believe will turn into a pawn-down draw, but a win can be pressed that is too difficult for them to see as a leaf node evaluation from 50+ plies distant.

Just to let you know, it is still possible (but getting increasingly unlikely) to defeat strong engines at correspondence time controls.
