Most Chess variants focus on the Knight jump to create novel pieces, such as R+N or B+N compounds in Capablanca Chess. As this adds 8 new moves to the piece, this immediately results in Queen-class pieces. (Even the B+N compound differs less than 1 Pawn in value from Q.)
I wanted to focus on King moves, for a change. Adding those to R or B only adds 4 new moves, and thus produces pieces of a value intermediate between Q and R, which in sinteresting in itself, as it offers new trading opportunities that are reasonably balanced. So I designed a new Chess variant, which I called 'ElvenChess' (which seemed a nice, thematic way for naming the new pieces).
In Elven Chess, there are 4 new pieces, which can be represented in over-the-board play by pieces from an extra orthodox Chess set, put on a Draughts chip. The latter is used to indicate that the piece now also can move as a King. For K and Q itself this is of course pointless, so only R, B, N and P are thus modified, to give the following pieces:
Goblin = R+K = Rook on pedestal
Elf = B+K = Bishop on pedestal
Dwarf = K = Pawn on pedestal (the Pawn moves are already included in the King moves,as Dwarfs have no double-push, do not capture e.p. and cannot promote).
Warlock = N+2K = Knight on pedestal of two Draughts chips.
The Warlock is a super-piece, gaining not just King moves, but is allowed to move twice as a King in one turn. (Hence it is put on two Draughts chips.) And it does not have to stop after a capture, so it can potentially capture two pieces in one turn, or capture and move on (or back!). In can also make its moves as a jump, meaning it can move as a Knight, but also jump over other pieces to the second square on any orthogonal or diagonal.
To keep this interesting piece in play, there are rules against trading Warlocks:
1) a Warlock cannot capture a protected Warlock if it would be 'in check' after that move. (So it must not be attacked, not even by a piece pinned on its King, and can thus certainly not be recaptured for a simple trade.)
2) after a non-Warlock captures a Warlock, the remaining Warlock becomes 'iron', and it is illegal to capture it. (This prevents indirect trading by a counter-strike.)
The variant is played on a 10x10 (International-Draughts) board; in the initial position d1=Elf, e1=Warlock, g1=Goblin and a1/j1=Dwarf.
