That's about 5 times the expected frequency!

That's less than half of what's expected.

tamerlano: I recognize your name from a couple of the World Internet Progressive Chess Championships.  (You and I were both participants in WIPCC 1998.)

I know you've also participated in similar events, for the Fischerrandom version of (Scottish) progressive chess.

If we were to have progressive chess versions added here at BK, I'd much rather see Fischerrandom versions--or at least have them offerred as alternatives.  To me, the opening moves from the standard starting position have been explored in great detail.  At the highest levels of play the range of acceptable opening moves is exceedingly narrow--at least in the Scottish version.  Playable theoretical novelties are very hard to find now.  (I've got one TN saved that I will not waste in any event less serious than a world championship.)

I think the Fischerrandom versions allow for more original analysis.  What do you think?

For my home set, I very carefully applied small (~1/8-inch) rub-on letters ("S", "G", "K", etc.) to the bottom right corner of each piece (other than the pawns, which I just left alone).  I used lower-case letters ("g","d", etc.) for the obverse (promoted) side of all of them.

A nice result--a unobtrusive little reminder whenever needed.

Andersp:     :-)    A programmer might come back to you with a request to clarify your requirements:

Would you like the new indicator to appear if a user has chosen to use Auto Pass for some games, but not all of them?

dicepro: I've thought a bit more about your comment about "...playing backgammon many times with doubling cube used right away...", which you described as being abusive.  Maybe I need to know more precisely what you mean by "right away".  If that means "as soon as legally possible", I don't have any strong moral feelings about such players' actions, but I'm absolutely convinced they're committing strategic errors (at most match scores, anyway), by voluntarily giving control of the cube to you without justification by the current game position and match score.  Possession of the cube has been described as a tool or a weapon--it's undeniably a thing of value at most match scores.  Generally speaking, I'd welcome the opportunity to play someone who wanted every game to be played at double the initial stakes, but with me having initial possession of the cube!  In such a case, I'd have to say "Please, let's sit and play--and don't forget to bring your wallet!!"

But if "right away" instead means "very early in the game"...well, I'm not sure what's abusive about that, either.  It might feel like one is being pressured earlier than expected, and such decision-making can be quite uncomfortable psychologically, at a variety of match scores.  Here, too, the opponent is offering more than a doubling of the stake--they are offering you sole possession of the cube, and the exclusive right to be the "abuser", one might say.

dicepro: I mentioned the possible use of a doubling cube in dice chess back in August on one of our boards.  Back then I was playing a lot of both backgammon and dice chess.  I found that some of my dice chess endings could be analyzed in terms of probabilities very similar to those we see in backgammon bearoff positions.  Some of my dice chess positions could be viewed as legimitaly being a "double and take", or "double and drop".  Never reached the point of being "too good to double", though, as no (back-)gammon possibilities loom in dice chess.    :-)

I've gotten to the point that I can no longer bear to play backgammon without the use of the cube.  I've been told that it's "not really" part of backgammon, but I'd argue that it's essential to the game, and to what is best about it strategically.

pauloaguia: I've felt the same way about the http://brainking.com/en/GameRules page.  The first times I got there to look for a particular game, I was at a bit of a loss.    Now I understand the list's order better.  With 104 games--and counting--supported, BK offers us an embarrassment of riches, as the saying goes.

Fencer:  I'm also having a problem with the "change icon" function, receiving a message: "This file type not supported."

I was sure the file was a satisfactory JPEG.  So I even tried re-submitting my existing icon file (which presumably should be okay), and got the exact same error message!
