Live broadcast of engine pv

[hgm]

I think Arena supports saving of the thinking time for each move, in the same way as WinBoard. From this and the TC tag the remaining time on the clock can be derived.

Got it to work.

Currently for version 241 only and the hopping needs a fix, point is, it is doable and quite easily.

Basically you can put anything in the file, even tell random jokes to entertain the audience in case the game is in a boring stage.

I am using chrome and it seems like the live pv is not consistent, after forced refresh it would show the pv before the move is made on the board but later, the pv is no longer updated. If you forced to refresh again, the live pv will show up and on later moves the live pv is no longer updated again. So I need to press the refresh button every time I wanted to see the live pv displayed.

I noticed the same with Firefox

There are a lot of incompatability issues among browsers.

Yes, I think that's the way TLCV create its clocks on the screen. However for web programming we will have to rely on the functions PGN4WEB offers.

Better now with Chrome?

TLCV gets the clocks (and everything else) directly from the GUI <-> engine communication (time and otim commands, after which it starts counting down independently for the side to move).

However for web programming we will have to rely on the functions PGN4WEB offers.

Why? For one, you can change it. Or you could use another viewer. Or you could write your own.

PGN4WEB is pretty useless anyway: it only does orthodox Chess....

I have plenty of viewers. E.g. http://hgm.nubati.net/variants/elven/ . Or the older one ('ChessLive!'): http://hgm.nubati.net/WCCC/game1/chess.html .

Wow it looks great

Finally implemented here.

I rewrite the pgn output of ChessGUI to a different format, now the pv (taken from TLCV_File.txt output from ChessGUI) is embeded as part of move comment, so now I get pgn and pv at the same time, send it to server via ftp, then extract the pv via pgn4web custom function, and just use a javascript to display the pv on the page, no more server scripts needed.

I think Matthias Gemuh author of ChessGUI can easily incorparate this change, adding pv to the move comment.

Any chance that you'll release a new Deuterium?

It is for release but I get something to do on ending after seeing live in broadcast. Imagine in kbp v kb, the kbp side has winning score even though from human perspective the position is just equal.
