Answers.Body: <p>This is quite a deep question that could be the subject of an interesting book.

Comments.Text: Great question! This thread might provide a start: https://chess.stackexchange.com/questions/9446/is-the-reversed-sicilian-kings-english-1-c4-e5-more-of-a-positional-and-quie. It seems that white's extra tempo in 1. c4 e5 does change the nature of the position, and gives black less prospects of an attack than white would have in 1. e4 c5. The answer in that thread shows one reason why this is.

Comments.Text: Your question is different, though, from the question in the other thread. It's probably the case that the English is slower and more strategic than the Sicilian. However, learning one may help learn the other, since the pawn structures are similar. What immediately comes to mind is how Magnus employed the English in the Rapid tie-breaks from the WCC 2018. I wonder if he felt comfortable with the English after all that preparation in the Sicilian. The sequences of moves can differ and the Sicilian is more sharp and tactical, but I would say that the two openings are both different and similar!

Comments.Text: It can be, but not as much as one might think. Due to the extra tempo White gets, Black is often denied playing the sharpest lines (that White could choose in the Open Sicilian).

  Is learning the opening 1. c4 e5 as white helpful in learning the opening 1. e4 c5? How about vice versa?
  
  Are the ideas behind the Sicilian Defence as black very similar to the ideas behind the English Opening as white?
