What Openings can I play against most openings? I'm looking for a &quot;universal&quot; opening. For example the King Indian which you can play against e4 and d4 and several other openings. What other openings (Black or White) can be played versus most classical openings?
As white the task is much easier because you make the first move and dictate terms.
You have:



g4 The Grob




f4 Bird's




Nf3 Reti




b3




b4 Sokolosky



As black you are more limited and have to play much more passively to be able to play the same moves against almost any white response.
The Hedgehog where you play to try and reach this kind of position:
 [fen &quot;2r1r1k1/1bqnbppp/pp1ppn2/8/2P1P3/8/PP3PPP/8 b - - 0 1&quot;]

The Hippopotamus which looks like this (Don't mess with the Hippo!):
 [fen &quot;r2qk2r/1bpnnpb1/pp1pp1pp/8/8/8/8/8 b - - 0 1&quot;]
