I don't think "if turn < 2:" , using < as infix operator is valid GAME code; I would expect something like "if < turn 2:"

I don't think you can do this in the Pre-Game code; I expect turn always to be 0 there, no matter how long the game is already progressing. Every time you submit or request the preset page GC would first execute the Pre-Game section, then the Pre-Move and Post-move sections for every stored move to set up the current position (increasing 'turn' in the process), and finally the Post-Game section. Preparation for the move to come (such as highlighting) should be done in the Post-Game section (where 'turn' will reflect the number of moves played so far).

307. Oracle. This piece comes from Lev Grigoriev's Thuderstruck Server Chess, and is actually one of the most interesting pieces there, especially for having such a simple move: it steps to any adjacent square, from which it may turn 45° and make one or more leaps of two spaces in a straight line. [K?fsSS]

The Playtest Applet gives this piece a score comparable to that of a Queen, and I tend to agree; its leaping and dual paths are balanced by its inability to reach the second, fourth, and other even-numbered perimeters in a single move.

Nonetheless, I made the model comparable to the Bishop in height. (Should I adjust it upwards, to match the Queen, do you think?)

What matters here is that CA is closely related to ND.

CA will even become it if we delete, for example, all squares of one color. Diagonal analogues are about that, and that’s how I started think about it.

Once tried to do so while in the road but copy-pasting notations from one place to PTA caused the page reload.

Maybe I will do it tomorrow.

Generally I tried this game in my mind, must be playable)

Diagonal analogue and rotary counterpart are slightly different things.

To me, it's not so important what you call it. I think it was clear that I meant what you call diagonal analogue. It does necessarily involve extending the distance as well as 45° rotation.

irrelevant rambling about rotation

But if we measure distance in elemental steps, then N moves 3 W steps, and C likewise moves 3 F steps.

The other way works by defining moves differently. Instead of measuring N's move as being 3 steps by the most basic step on the same grid, we can say it's 2 K steps (where both W and F = 1). That way a rotation either increases or decreases the actual distance of the move, while preserving the measured distance in K steps.

So it all depends on how distance is measured. I like to think of rotation as replacing all Ws with Fs; and the second relation as inversion, swapping Ws and Fs for each other, but they do both involve both rotation and absolute distance changes.

"Rotational counterparts" might feel less natural since they don't have the weird effect of increasing some distances while decreasing others. Imagine rotating FD and getting WA. The short move got shorter and the long one longer! A diagonal analogue preserves the shape of the move without distortion. It's also like a screw—you can twist it two different ways to get different results.

What matters here is that CA is closely related to ND.

N is not counterpart for C, but Z is.

N has not a rotary counterpart at all because its moves are the axis of estimating that trait.

Diagonal analogue and rotary counterpart are slightly different things. For example, F and W are both these things, but diagonal analogue for F is D, for D is (naturally) A, for A is WX and so forth. It’s done by multiplying on square root from 2.

Game Reviews are the same as Comments.

The query string had the right parameters, but it needed to set gamesonly and ratingsonly to true instead of just including them. I corrected that, and it now works properly.
