If you have a d-pawn it is not a Marocy Bind.
Maroczy Bind
Suppose white has pawn on e4 and c4 but also has a pawn either on d3 or d4 ......Will that be still called as Maroczy Bind or not.....Look at below example is this a Maroczy bind condition.....??
No. In the Maróczy Bind, White's d-pawn and Black's c-pawn are exchanged. Here's an example. (The Maróczy Bind is a pawn formation in chess. It is usually, but not always, played used against the Sicilian Defense. It is characterized by white pawns on c4 and e4, with White's d-pawn having been exchanged for Black's c-pawn.)
I pressume the maroczy bind is good for white in this position?
Yes, it's one of White's main options against the Accelerated Dragon variation.
What is the main point of c4 in maroczy bind
Domination of d5.
It's commonly played in the Sicilian Accelerated Dragon, Sicilian Taimanov, and the English Opening (Symmetrical Variation with an early d4 by White).
White dominates d5, which causes problems for Black. What that problem is depends on the line played.
In lines with an early ...e6, like the Taimanov Sicilian or English Opening lines, both of which usually lead to a hedgehog structure by Black, the d-pawn can be weak and White is doing all he can to avoid a ...d5 break, and possibly attacking weaknesses on b6 and d6.
In lines with an early ...g6, like the Accelerated Dragon, ...e6 here becomes very undesirable because it weakens the dark squares severely. The d6-pawn, the f6-square, etc. It becomes even worse if White trades off the Dark Squared Bishops. Therefore, ...e6 is usually undesirible, and so White will try to time properly the placement of a Knight on d5, where if Black trades on d5 (usually with the Bishop on e6), then White should take with the e-pawn, NOT the c-pawn leading to a symmetrical position. By taking the with the e-pawn, White opens the e-file to Black's sore spot on e7. Now White shifts the energy from covering d5 and attacking d6 to covering e6 and attacking e7.
The Maroczy Bind is not a blood-bath type of opening. It requires a very methodical and flexible attack by White. Sometimes White must open up the Kingside. Sometimes it's going for a Queenside majority (after the trade on d5). Sometimes it's an attack down the d-file (especially if no trade occurs on d5).
Pawn structure for White is typically a2-b3-c4-e4-f3-g2-h2.
On whether the Maroczy Bind is good for white, in the position poster by chesspatzer, I would say probably.
The evaluation of these positions is still controversial and they have been known for a very long time. But there is no shortage of excellent players who like to play it as white, Calsen for example.
The point of c4? The idea is that the pawns on c4 and e4 give white a lot of space and particularly to permanently prevent black from playing d5, which is supposed to prevent black from ever freeing his position. That is why it is called a bind.
Of course if white could always do this nobody would play it as black. Black can try to break out with d5 or b5, often at the cost of a pawn.
