Comments.Text: my houdini **'not properly flows'** even still counting node at approx. over **`214 Billion Node`**. And it show current value at node approx. over **`166 Billion Node`** with Indian variation (`1. d4 Nf6` `2. c4 e6` `...`). So I will suspended my research now..  thanks to all viewer and for the appreciation..

  I am just an ordinary chess player who does not know about Chess **Tournament** even just a little thing,

  in early (at 3 games) seem to be played and transposed to **`Benoni variation`**,   
  are there some information that in the real **Tournament**, it is often to happened too??
  
  **if it is not,**
  
  what kind of variation which seem to be played in any **Tournament**,   
  because I want to learn opening and it's transposed to another which was proved and tested in **Tournament** first.. ^^

  **EDIT:** You seem to be concerned if the opening is "tournament tested." I can affirm that almost all of the mainstream openings are well-tested, and you can figure out what these are yourself by doing the appropriate research online (i.e, which openings are most commonly played. See the links I supplied with [this post](https://chess.stackexchange.com/a/2432/1382).)

  It would be great if you could clarify your exact question, but I feel as if you're asking if the Benoni Defense is a respectable opening. The Benoni positions arise after:
  
  ```
  [FEN ""]

  ```
  
  And here Black can play the Benko Gambit with `3...b5`or go into more typical Benoni lines with `3...e6`. Of course, there are many other moves that can transpose into Benoni positions.
  
  As for its reputation, the Benoni is certainly playable at all levels and has been played in World Championship matches. However, in recent times, the Benoni has been considered inferior to other Indian/Hypermodern defenses against the Queen Pawn openings such as the Grünfeld or Queen's Indian.
