SjaakII 1.0 RC1

[Evert]

OK, great! This one works. I could castle. It does not implement 'guarding'?

No, not yet. It takes very little to add it at this point, but there are one or two places where it is explicitly assumed that there are only two castling moves.

My understanding is that "guarding" is an addition to Omega Chess (in a variation by the same author called "Omega Chess Advanced"), which also includes a new piece, the Fool (a Chamaeleon that has to be gated in before move 20, and/or optionally a type of Immobiliser) and an optional replacement for the Knight (NmZ). The Fool is a problematic piece to add without adding a lot of code.

Ah, OK, it is just in the extension. I wasn't aware of that. Then it isn't really worth it. I was just curies whether it would work in XBoard. I suppose I could configure the current version of Sjaak to do the guarding instead of castling?

Sure. This is probably easiest to do with Omicron Chess because it is defined in the config file, but it can be done with Omega Chess too if you're willing to edit the configuration in variants.h.

For Omicron Chess, just changing

Code: Select all

Castle: white g2-i2 with j2
Castle: white g2-e2 with c2
Castle: black g9-i9 with h9
Castle: black g9-e9 with j9

to

Code: Select all

Castle: white f2-h2 with j2
Castle: white f2-d2 with c2
Castle: black f9-h9 with h9
Castle: black f9-d9 with j9

should do it (not fully tested though).

Setup in winboard 4.8.0b as s-chess, windows 7. Then run in analyze mode, but it rejected the move e2e4.

It seems it expects the man file in a different directory then where it actually is.

XBoard still seems to have a problem with promotions: it does trigger the procedure, but it fails to attache the chosen suffix to the move it sends to the engine, Will fix that this weekend.

I found a fix for this. But these 'highlight-induced promotions' still seem to function sub-optimally. At least when sweepPromotions is on. (And when it is off you have the problem that the promotion popup does not list the Wizzard and Champion as possible promotion choices.)

Normally sweepPromotions would already morph the Pawn into a Queen when it is picked up, and allow you to change it by moving it to the promotion square through a detour, pulling it backwards first. But here it only realizes it is a promotion when the piece is actually released on the purple square, and as it is too late to select anything then, it picks the default Queen. The only way to make a different selection is now to enter the promotion as a click-click move: then the down-click on purple makes XBoard realize this is a promotion, making the Queen appear on the to-square, and it allows you then to change the Queen into something else by dragging down the mouse before you release the second click.

The latter procedure is the only way for Shogi promotions, where you don't know in advance if a picked-up piece will move into the zone or not. I guess the same info could be extracted from the highlight command by checking if all the highlighted squares are purple; if they are, promotion is unavoidable, and the procedure could already be triggered when the piece is picked up. The problem is that unlike the case where the built-in move generator knows this, the information now is not really available when the piece is picked up for dragging, but only after the highlight response to the lift command comes in.

Ok, the immediate problem with analysis mode was caused by a change in the way moves are parsed, but analysis mode turns out to have been badly broken. I can't tell how it ever could have worked in the first place (at least not if you tried to undo moves and input new ones).

Should be fixed locally, but I do have one comment/question regarding the implementation and the CECP specs. Specifically:

new Reset position to start of game but stay in analyze mode.

In normal mode, "new" has the following description if we cut out all cruft that doesn't apply in analysis (force) mode:

new

Reset the board to the standard chess starting position.
[…]
Remove any search depth limit previously set by the sd command.

Apparently, "reset the board to the standard chess starting position." also implies switching back to variant "normal". I'm assuming this is not intended to be the case for "new" in analysis mode, in other words, they're different commands despite being called the same (I understand the historical reasons for this distinction).
