I have been playing chess again for two or three months, after a period of about twenty years of interruption. In a game against a human adversary, I noticed that my opponent was taking the time to build a large wall of pawns similar to the following picture, while I was on my side playing with stronger pieces.
8/8/8/8/P1P1P1P1/1P1P1P1P/8/8 w KQkq - 0 1
I found quite difficult to play aggressively against such a wall. Recently I tried the same and found this strategy rather efficient (of course the wall is never perfect but the picture gives the idea).
I would like to know a little more about this style of playing. Does it have a name? Is it known to be efficient?
