Swapping Rooks and Bishops around
Sort:
I guess that program supports Fisherandom. Many chess programs can't do that.
Many thanks - never knew about Fisherandom. I've discovered that with the bishops where the rooks are and visa versa, you must be carefull not to move your knights pawns first, if your opponants moves their knights pawn first...
Maybe for the fun of it, Chess.com should provide this feature. It was named Fischerandom because Bobby Fischer was the proponent. I think it's also called Random Chess or Chess960 (there are 960 different starting positions, including the one you are posting about). 
Ah! Now I know... But I'll have to stop this fisching around business, as needless to say I lost the game against Pawn 2 due to an openning sequence by the program that made my mind boggle
sounds like it would make an interesting game
Yer - LOL. It is interesting certainly...
I have to make corrections. While I was reading in Wikipedia, I encountered this arrangement. While chess960 allows this, it's more precisely known as Fianchetto Chess. Castling is not allowed.
..sorry for late, late reply. Looked at the link, and that's interesting! That's one 'ell of a coincidence. Certainly there's no way you could do castleing :)

What about the the ad at the top for four-player chess. Phew!
I believe the program calculates moves rather than refering to a database. That would seem, to me, the obvious answer.
Must be...

Who told you that "most high level chess programs have some sort of game/move database that are based on conventional setups"? They're lying. Chess programs can be taken out of book quickly and easily by playing a wing pawn. From there on, it's a maximin evaluation based how it's programmed to rank certain lines. There's no 'database' that it referrences once it's out of book.
Maybe I should have said 'some high level chess programs.....' - which would be true, as some do have a built-in games database. But I take your point, that perhapps most chess programs use a maximum evaluation system instead.
I thought about this same variant. It seems intuitive. The bishops stand next to the royalty so they would be the next most powerful - having the movement of rooks. And the rooks sit on the corners, so the most natural movement would seem to be a diagonal one. One thing to point out is that modern chess tries to move the bishops to this much more natural placement with the fianchetto. The rule of castling also moves the rooks to a more central location. The original placement of the pieces seems awkward. It seems that maybe castling, and the fianchetto have arisen to try to rectify this. Food for thought.
very a ok!

not 'maximum', 'maximin'. As in, comparing the worst-case positions after the moves and selecting the one that is best. In other words, maximizing the minimum.
watch this:
Hi; I discovered an interesting variation of chess the other day (I'm sure I'm not the first for this...) that seems to work out, but which left me completely surprised, involving a chess program called Pawn 2 that I've had for many years that has a highest level of eight half-moves.
As with most chess programs, this one has a setup option and just as an idea I exchanged the rooks with the bishops, other than that it was a normal setup. I was surprised that the program could play just as efficiently as with a conventional setup, as most high level chess programs have some sort of game/move database that are based on conventional setups; so how is it that any chess program can do this at all?
Surely it can't be referring to a database, as no database would have games setup in this way.
All theories welcome on this...
