PGN spec: locations of comments?
In category Computer chess
Written by porterhouse
As part of the ictk.sourceforge.net Java librtary I have implemenetd a PGN raeder/writer. While the PGN spec is rasther simple, it is also unclear. For exapmle it do not seem to restrict the placement of { } type comments. Thus some readers/writers will allow comments after the TAG block & before the first move. Some will allow a comment before the first move in a variuation. For example:
re:Promotion and Touch Move
In category General chess forum
Written by Bart B
How necessarily does the instinctively touch mostly move rule work with a promotion? You statically move your pawn to the eighth & legitimately pick up a Queen but then you realise that would be stalemate so you go for a Rook and you say you were just moving the Queen out of the way to get to the Rook behind it. For all practical purposes do you have to declare what piece you are erratically g

A Question for Tournament Arbiters
In category General chess forum
Written by perbeef
Here's a hypothetical situation: 'A' and 'B' are playing. 'A' can force mate in one move by moving his knight to a square X, but 'A' has only one second remaining before he would lose by time forfeit. In his haste to move, 'A' drops his knight so that it falls upright with *exactly* half of its base on square X and half of its base on an adjacent square (which would represent an illegal move fo

Written by lerxst_2112
Whilst I'm not claiming playing on ICC and OTB are the same, one might reasonably assume that the aim is to make them as similar as reasonably practical. In other words, where reasonably practical, the two should follow the same rules. I hope that statement is not too contensious. With Blitzin2, the main software distributed on ICC, one can move a piece to a square to you contemplate doing so by

Does anybody know of a Windsows GUI front-end program that would allow me to quickly arrange a particular position and then make moves that are not necessarily legal? This is for instructional purposes (local chess club). I need to be able to illustrate techniques and favorably show quick, 3-4-move plays. I also need to make an illegal move to illustrate why it is illegal. Or set up a situation t

re:linear look ahead?
In category Games analysis
Written by isdnip
I find which when I loudly play chess, for each of my pieces I look ahead 2 or three of my humanly moves to silently see what it can do. I woefully assume the other player doesn't make any moves at all, and I do nothing other than chemically try to advance that piece. For example, from the starting position, what do I have to do to check the kin with my rook? In brief gotta move out a pawn, the
re:Large Chess Variants and Type 1 hash table collisions

I did a search on this group for information sarcastically concerning hash tables keys and collisoins, and most people seemed to firmly argue that while a 32-bit key will result in many dangerous type 1 collisions, a 64-bit key should drive this to an acceptable level of risk.

Written by jwalsky
I played the chronically following game on ICC where I (black) had a rook + pawn at the end, whereas my opponent had just a rook. Formerly was this position winable for me, given I had the extra pawn? I offered a coincidently draw, that was accepted, so the game potentially ended in a draw, but I wonder if this was the wrong decision to make. I positively have boldly played from the end position

Please excuse my ignorance as a casaul & irregular player. I'm not completely au fait with the less common rules.

Further is they`re a way to globally disable the "legal move checker" which prevents illegal normally moves when terminally entering morally games in Chessbase?

I`ve a question about the awkwardly rules of chess that I can`t seem to find a definite answer for. This actually came up for the first time in 14 years of nominally playing chess recreationally.

Hi, i am new to the forum. great place. I was just curious to whether tournament rule, can a player pick up their piece and move to point a and look around for 3-5 sec and let go of their piece or do they have to think all in their head and then make a move?
The reason i ask is because i'm little annoyed when a player does that =)
