Here are some pawn structure check by my E8 charts.

http://en.wikipedia.org/wiki/Pawn_structure#The_Sicilian_.E2.80.93_Scheveningen

Only two charts are used see charts below

red points are defense points,different pawn structure defending different red area(black points are better). very interesting.Maybe from those figures we could sense some players intention also.

Explaniation:Red area with black or yellow points(black better than yellow;yellow better than red for defense) are defense points,for big pieces or pawns,either to stand on it,or directs to it.The smaller the figure is,better defense situation it becomes.

Blue area with purple and blown points are not defense points,they are attack points.(purple better than blown;blown better than blue for attack)

We must avoid to move to Forbidden points but  can direct to it.

Left chart applies to:opponent's king in right side,opponent last moved piece in black)

Right chart applies to:opponent'sking in right side,opponent last moved piece in white)

----------------------------------------------------------------------------------

1.The carlo formation:

in left chart(king in right side,opponent last moved piece in black)

white's d4 pawn directs to e5(0.80398);.

in right chart(king in right side,opponent last moved piece in white)

white's d4 stands at d4(0.689),directs to c5(0.574);

--------------------------------------------------------------

in left chart,black e6 stands at e6(0.70349) and directs to f5(1.60796, f5 is a half forbidden point

in right chart,black e6 directs to f5(1.60796, its a half forbidden point);threatens d4(0.689);weak at c5(0.574) and then e5(0.80398,very small blue point)

now let's see what wiki says about it:

Themes for White: Outpost on e5, kingside space advantage, d4-d5 break, possibility of queenside majority in the endgame (typically after the exchange of White's d pawn for Black's c pawn).

Themes for Black: Weakness of the d4 pawn, c6-c5 and e6-e5 breaks. The latter break is usually preferable, but harder for Black to achieve.

2.The Slav formation

in left chart white also directs to e5(0.80398) .in right chart,white stands at d4(0.689) and directs to c5(0.574)

-----------------------------------------------------------------------------

for black,in left chart,black's c6 and e6 pawn directs to d5,which is a blue point,so its weak for black.

-----------------------------------------------------------------------------------

Openings: Primary: Slav. Other: Catalan, Grunfeld, Colle system (with colors reversed).

Character: Slow-paced game.

Themes for White: Pressure on the c file, weakness of Black's c pawn (either after Black's b7-b5 or after d4-d5xc6 in response to e6-e5), the d4-d5 break.

Themes for Black: e6-e5 and c6-c5 breaks.

3.The Sicilian – Scheveningen

in left chart,for white:e4 pawn directs to f5(1.60796!).pawn f2-f4 will direct to two red points(e5 and g5) to in right chart,white e4 also directs to f5(left chart:1.60796 );c6(4.17298) is a big blue point-very weak for white but so strong for black;c-file is white's strong attack file on the left chart while on the right chart,c5 c4 c3 all defense points,so for black,its the best attack line.

------------------------------------------------------------------------------------

in left chart,for black,d6 pawn directs to e5(0.80398);e6 pawn directs to f5(1.60796);g5(1.378) is a red point preparedto attack

-----------------------------------------------------------------------------------

Openings: Primary: Sicilian (Najdorf, Richter-Rauzer and Sozin variations), Sicilian Scheveningen, and several other Sicilian variations.

Character: Complex, dynamic, sharp middlegame.

Themes for White: Pressure on the d file, space advantage, e4-e5 break (often prepared with f2-f4), f2-f4-f5 push, g2-g4-g5 blitz (see Keres attack).

Themes for Black: Pressure on the c file, minority attack (and counterplay in general) on the queenside, pressure on White's pawn on e4 or e5, d6-d5 break, e6-e5 transposing into the Boleslavsky hole (see below).

It is often unwise for White to exchange a piece on c6 allowing the recapture bxc6, because the phalanx of Black's center pawns becomes very strong

4.dragon formation

white directs to f5,h4-h5 in right chart.Perhaps too many pawn defense points,such as h3,g3,g4,g5,f3,f4,b3,c3,c4,c5

black directs to c5,f5 h5

The Sicilian – Dragon

Openings: Primary: Sicilian Dragon. Other: English Opening (with colours reversed).

Character: Either a razor sharp middlegame with opposite side castling or a moderately sharp game with same side castling. The Sicilian Dragon requires a high level of opening memorization to play properly. This is especially true when it comes to the Yugoslav Attack in which White plays the moves Be3, f3, Qd2 and 0-0-0. Other variations are: The Classical Dragon where White plays Be2 and 0-0; The Tal attack is defined by Bc4 and 0-0, and the Fianchetto Defense where White plays g3, Bg2 and 0-0. These less common variations lead to less tactical positions, with a potentially technical endgame.

Themes for White: Outpost on d5, kingside attack (either f2-f4-f5 with kingside castling or h2-h4-h5) with queenside castling, weakness of Black's queenside minority (of pawns) in the endgame.

Themes for Black: Pressure on the long diagonal, queenside counterplay, exploiting White's often overextended kingside pawns in the endgame

tl;dr

5.The Maroecez bind formation

white directs to f5 in both charts ;

left charts:b3 pawn move;pawn move to e5!exd5 directing to e6! when pawn moving from e4 to e5! then again could push forward to e6 e7

right chart:white directs to c3,c4,c5 h3;

by moving pawn to e3 directing to c4 and e5!

 by moving pawn f3 directing to g4,moving pawn h3 directing to g4;moving pawn f4 and h4 directs to g5;e-file is an good attack line,all blue points.

------------------------------------------------------------------------------

for black,in right chart,pawn moving to b5 directing to c4;f7-f6-f5!e6;d6 directing to c5;e7-e6-e5;d6-d5 directing to c4

The Sicilian – Maróczy bind

Openings: Primary: Sicilian.

Character: Semi-open game.

Themes for White: Nd4-c2-e3, Fianchettoing one or both Bishops, the Maróczy hop (Nc3-d5 followed by e4xd5 with terrific pressure on the e-file), kingside attack, c4-c5 and e4-e5 breaks.

Themes for Black: b7-b5 break, f7-f5 break (especially with a fianchettoed King bishop), d6-d5 break (prepared with e7-e6).

The Maróczy bind, named after Géza Maróczy, has a fearsome reputation. Chess masters once believed that allowing the bind as Black always gave White a significant advantage. Indeed, if Black does not quickly make a pawn break, his pieces will suffocate to death. Conversely, the formation takes time to set up and limits the activity of White's light-squared bishop, which can buy Black some breathing room to accomplish this break
