Trampoline Chess. Each player has a Trampoline that allows friendly pieces to make a second move. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]

Good point, but don't forget the link: Taxi. Now you mention it I recall other examples of other things that contain pieces: the ships in David Jagger's PiRaTeKnIcS, the trains in Ralph Betza's PASGL 312 Chess and François Tremblay's Subway Chess, and the Trojan Horses in Gary Gifford's Shatranj of Troy. Some of these can capture in their own right, of course, but others need something 'on board' them.

How about the 2 taxis in Taxi, the Nuclear C.a.B. Chess game? They are described as mobile board squares. They move other pieces around but are themselves just 2 squares from opposite ends of the board.

You could be right, I was just lumping them together as 'not covered anywhere else'. One further connection is that Ferry moves along the River, but it could be regarded as a multi-cell non-capturer moving along a pair of ranks. They seem to me to fall into three groups.
	The Ferry, Halter, and Trampoline can all move, either under their own steam or with the aid of another piece, but cannot capture and have a different effect on pieces. They can therefore be considered special cases of non-capturing pieces.
	The Raft and Tardis are board sections that move - and again do not capture. They take their pieces with them.
	The Bridge, Fortress, and River do not change their location on the board but still affect how pieces move.

Conflating nonmoving board features with noncapturing pieces doesn't make a lot of sense to me. The only overlap seems to be the Tardis, which is a bit of board topology that can be moved by the player.

I've just remembered another myself, the Bridge from my own Anglis Qi. So that makes the list so far the Bridge of Anglis Qi, Ferry of Ferry Xiang Qi, Fortress/Palace of standard Xiang Qi, Halter of VeCoTha, Pole of Pole Chess, Raft of Flossschach, River of standard Xiang Qi, Tardis of Tardis Taijitu, and Trampoline of this variant. Any others that I've missed?

Well you could go further and have Hopping pieces with the option to change direction at the piece that they hop, regardless of what that piece is. Might these be termed Trampolining pieces? The Moose (see my comment on the Squirrel) is a very specialised example.

Idle thoughts: taking the name 'trampoline' literally, allow a slider continuing across a trampoline without changing direction to move as a hopper. I wonder if it'd make the trampoline too powerful though.

Also, hybrid Trampoline/Pole Chess? (TramPoleIne?) One piece expands move options, the other restricts...

Roberto Lavieri used 'batteries' to augment the power of his pieces, and others picked up on it - well, one anyhow, if I recall correctly. Gary Gifford used mirrors, and I think Jeremy Good might have experimented with them. Shuuro, the recent commercial game, uses immobile blocks that knights can ignore, and even land upon.

A similar principle can be employed by giving an already existent piece the capacity to enhance the movement of other pieces, as in my Dromedary Chess
and Royal Cannon Chess
In the above two variants it's the king who energizes the adjacent piece.

Also the following two variants are pertinent to the discussion.
Hopper Chess
Gunnery Chess

To Charles Gilman's previous comment: The rafts in Floßschach may apply as
non-pieces. Also various kinds of teleporters (not so rarely seen) and
tunnels or wormholes ...

I agree with Garth Wallace's view on the Queen. The Trampoline adds to an increasing number of 'non-pieces' that should perhaps warrant their own article. So far I can list the Ferry from Ferry Xiang Qi, Fortress/Palace of standard Xiang Qi, Halter of VeCoTha, Pole or Pole Chess, River of standard Xiang Qi, Tardis of Tardis Taijitu, and Trampoline of this variant. There are certainly others that have slipped my mind. Can anyone think of them off hand?

Could the Trampoline be perceived as a piece that allows bifurcation? What other possibilities of pieces are there that allow pieces to bifurcate by them? Excellent piece idea.

Garth Wallace wrote on 2009-12-07 UTC
One possibility for limiting the queen in this case is to allow it to 'bounce' only as the component used to move to the trampoline. So if it slides to the trampoline orthagonally, it can only move away orthagonally, and if it moves to the trampoline diagonally, it can only move away diagonally. In other words, the queen could only move like a rook or like a bishop on a single turn.

Thanks, Alfred! I don't recall seeing Hop Chess before. I've updated the page for this game acknowledging the similarity and priority.

Alfred Pfeiffer wrote on 2009-12-07 UTC
Joao Pedro Neto invented a similar game in 2005. He named it 'Hopp Chess'. 
The description is on the 'Trabsact Sagme Diaries', entry of May 17, 2005:

Thanks for a real original and imaginative piece :Trampoline.
