Chess Variants — Triangle Chess and Donut Chess

I’ve been doodling lots of chess boards today:

I <3 the Wikipedia Sandbox.

Before the details, here’s an xkcd chess set I designed:

Not much to say about it, really. If I ever get a 3D printer…

Now for the interesting part:

Additional rules:

Triangle Chess: Pawns can only move forward along diagonals, and attack one square directly ahead. All other pieces move as usual.

Donut Chess: All pieces can wrap around the edges of the board like in pacman (toroidal topology, hence “donut”). Pawns can move in any direction, but only one square orthogonally when moving and diagonally when attacking. Pawns can only move two squares on their first move and only if they’re moving outwards from the starting rectangle. Rooks can only move 4 squares; bishops can move 3. Queens can move 3 diagonally or 4 orthogonally.

I’ve played a game of Donut Chess, without the directional limitation on pawns moving two squares. It was fun, but tends to be rather short. I’ve never played Triangle Chess. I have also considered “Non-Donut Chess”, with the same board setup but normal topology.
