Among all the invented chess variants (on this site or in Pritchard
Encyclopedia), I have selected 10 ideas, that according to me prevail on
others, whether they gave birth to a wealth of new variants, whether they
synthesized other older partial ideas, or for their unique originality:

1) "ALICE CHESS", flavour of third Dimension (see also "linear chess" in
1D): each move swaps the piece in another dimension
2) "SYNCHRONOUS CHESS", no time laps between moves: each move is played
simultaneously with new prevailing capture rules
3) "LOSING CHESS", reversed strategy: force the opponent to capture our own
piece until nothing remains
4) "CAPABLANCA's CHESS", new pieces combinations: introduce new pieces like
R+N or B+N, queen being already B+R: see faery chess in general
5) "ULTIMA CHESS", homogeneous pieces with different way to capture: 
immobilization, withdrawing, coordination, multiple capture, mimicking...
6) "EQUAL ARMIES", different forces: opponent handle different kind of
pieces, but overall balanced
7) "HEXAGONAL CHESS", new board shape: each piece has different numbers of
neighbouring squares (see also Strander's game, where board shape is formed
during play)
8) "DICE CHESS", where chance (randomness) play a role in piece order move
9) "BUGHOUSE GAME", also called 4 players blitz: played in tandem, with
captured pieces being given to ally, it requires cooperation
10) "PATIENCE CHESS", solo game: some rules allow you to move both sides,
and you lose if winning is not possible by any side 

PS some games may have different names and differ slightly from the short
description proposed here
