First example with using a FEN string for the situation, and starting from there. Comments are given in braces.
<pre><code>[ctpgn id=fen fen="r5k1/ppqb2pp/2n1pr2/3pN1QP/2pP2B1/P1P5/2P2PP1/R3R1K1 w - - 0 23"]

Now a whole game, with only some comments.
<pre><code>[ctpgn id=demo] 1. e4 c5 2. Nf3 d6 3. c3 g6 4. d4 Bg7 {richtig wäre cxd4} 5. dxc5 dxc5 $2 6. Qxd8+ Kxd8 7. Be3 b6
8. Bc4 Be6 $4 9. Bxe6 fxe6 10. Ng5 Kc8 {Qualitäts- oder Firgurenverlust ist nicht zu vermeiden}
11. Nf7 Nc6 12. Nd2 Nf6 13. Nxh8 Bxh8 14. f3 e5 $2 {sperrt seinen Läufer ein, der erst einmal nicht mehr mitspielt}
15. a4 Kb7 16. Ke2 Nh5 17. g3 Ng7 18. Rhd1 Rd8 19. Nc4 Ne6 20. Rxd8 Nexd8 21. Bf2 Kc7 22. a5 Nb7 23. axb6+ axb6
24. Ra8 Bf6 25. Ne3 e6 26. Rf8 Be7 27. Rh8 h5 28. Rh6 Bg5 29. Rxg6 Bxe3 {Schwarz gibt in hoffnungsloser Stellung auf} * [/ctpgn]
</code></pre>
Again the finish of a game with the result. See the variations with their syntax, they are tricky (at the moment).
<pre><code>[ctpgn id=markus fen="4r1k1/1p1q3p/p5r1/3n4/3p4/bP1P3P/P1R2BP1/3Q1RK1 b - - 0 36"]
36. .. Ne3 ( 36. .. Qxh3 37. Bxd4 (37. Bg3 Rxg3 {typische Fritz-Züge}) 37. .. Bd6 38. Re1
(38. g4 Rxg4+ {gewinnt schneller}) 38. .. Qh2+ 39. Kf1 Qh1+ 40. Bg1 Rf8+ 41. Qf3 Rxf3+ 42. gxf3 Qxg1+
43. Ke2 Re6+ 44. Kd2 Qxe1#) 37. Bxe3 Rxe3 38. Qh5 Rxh3 39. Qxg6+ {Verzweifelung} hxg6
40. gxh3 Qxh3 41. Rcf2 Qxd3 42. Rf7 Qg3+ 43. Kh1 d3 (43. .. Qh3+ 44. Kg1 d3 {geht noch schneller})
44. R7f3 Qh4+ 45. Kg2 d2 46. Rd3 Qe4+ 47. Rff3 Qe2+ 48. Kg3 d1=Q {sollte reichen, Weiß gibt auf} 0-1 [/ctpgn]

Changelog: 
Version 1.5 
– Tested on WordPress 3.7.1
Version 1.4 
– Updated the jsPgnViewer javascript to the latest version (0.6.7).
Version 1.3 
– Fixed error that caused preview not to show up within the WordPress admin after changes were made.
Version 1.2 
– Compatibility with WPMU improved. Made changes to how code is inserted into posts. Instead of game it now defaults to ###pgn### game %%%pgn%%% because this is a bit more compatible, especially with WordPress MU. The tags will still work, though.
