Re: Opening book read speed

I think you should consider converting your current format into something more efficient. See for example https://github.com/sshivaji/polyglot - supports reading/writing Polyglot book format (GPL). --Jon I agree. There are many FREE tools out there to create and maintain opening books in the polygl...

QSearch and endgames

When an engine doesn't use EGTBs or if they are disabled, what is a good rule about when to / when not to call QSearch prior to calling specialized endgame code, such as a mop-up routine? I'm proceeding with the premise that if the number of pieces is left is low enough to trigger endgame code, then...

winboard.nl tournaments and Arena

I had forgotten about it, but Arena has support for ISC.

I just tested logging in to winboard.nl using Arena and it connected me OK.
Does/has anyone used Arena rather than winboard?
if so, can you pass along any suggestions as to how Arena should be configured to insure a smooth experience?

Re: Bad Bishop question

1. "We" have one bishop, and the goal is to make it easier for it to move around, so we want more of our pawns on the opposite color. we can't control what the opponent does. 2. if we have zero or 2 pawns, then moving around pawns doesn't help our bishops, but, it can punish the opponent's single b...

Re: Bad Bishop question

Thanks for your explanation. Upon further thought, I see two possibilities though. 1. "We" have one bishop, and the goal is to make it easier for it to move around, so we want more of our pawns on the opposite color. we can't control what the opponent does. 2. if we have zero or 2 pawns, then moving...

Re: UCI Hash Usage Rules

Wow, I didn't expect the original question to turn into a major legal battle. I thought I would request a ruling because I was testing an evaluation hash (not a pawn hash) and its size was a lot bigger than 1M. In fact, I made it 10% the size of the main hash. I was adjusting the size of the main ha...

Bad Bishop question

Bad Bishop: If you have one bishop, it is better to have your pawns on squares on the opposition color than that of the lone bishop. That is how I understand the definition. Now comes the more complicated part. That definition works best if the opponent doesn't have a bishop, but what if the opponen...

Notation question

In this position... R7/4k3/8/8/8/p7/r3p3/4K3 b - - 0 1 it is black to move. How should one describe the position in terms of end game, should it be KRPPKR (black pieces first since it is black to move), or KRKRPP (showing whites pieces first regardless of who's side it is to move). Perhaps the rule ...
