    hello everybody,

    I'm new in chess.com. Isn't there a board where we can try some moves during the game without submitting them..... if i want to try 5 or 6 moves ahead what should i do?

    I think you click on the "moves" tab and at the bottom you click on the analysis board.Smile and welcome to chess.com!

    This question gets asked a lot on ratings topics, but I haven't seen it answered....if it's been asked and answered 14 times on earlier pages of this thread, sorry:

    when your ratings change, is it by the amount shown when you accepted the challenge? or are ratings fluctuations DURING the game taken into account too?

    ILLYRA:

    There is a forum focused on the question.  I couldn't find it, but if someone else would kindly do so and post the link?

    Mine? 

    There is a forum that answers Illyra's question and I couldn't find it, but I have read it.  I want someone else to find it for me so I don't have to search through 150 forums with the word "Rating" in them...

    But only if you can play faster then him.  If he plays faster, then he starves you out!

    If you really want an interesting article on the rating system read the article about Mark Glickman in the 2006 October Issue of Chess Life. It does an excellent job in explaining the system (Glicko and Glicko 2). It gives you the essential formula used for calculating ratings. The equation looks very simple. However, when you start to get into refinements, etc, you see how difficult creating a rating system really is. The article has some good information on the development, from a not to difficult mathematical standpoint.

    It's not how well you play the game, it's if you win or lose! Cool

    Yeap, it's the case for me. I'm good at short games, but I always lose in long games.

    sorry viswanathan, but a queen is actually worth 9, (not ten) pawns.

    turtle, the general points system followed is as follows:

    pawn - 1pt.

    knight/bishop - 3pts.

    rook - 5pts.

    queen - 10pts.

    of course points are not everything... the position of your piece also matters.. for example you might not mind losing a bishop or rook to save a pawn on the 7th row.. and points dont have any bearing on the game result.. it is just a basic framework to help beginners understand the value of different pieces


     Also, the king is worth the whole game

    Answering my own question, it looks like ratings change based on where you stand at the moment the game ends.  That seems right from what I've observed on here.

    So when you first sign on for a game, let's say the Vegas odds line reads "Win: +42  Lose: - 112."   Then, during the course of play, another game of yours ends and you win it.   So now your rating is higher.  So if you then win the game that promised you 42 points, you'll now only get like +15 because your rating improved during the game, altering the original contract.

    (Just a little confusion I had over how correspondance chess is rated.)

    Something I note about ratings that doesn't seem right: you can get an inflated rating by beating lesser players without challenging yourself to play better ones.

    I was rated 1380 at the start of the Ruy tournament, so I was put in the 1200-1400 bracket.  Being 2nd-seeded in my pool, I've pulled a bunch of wins against sub-1300 players.  My rating has gone to 1480.  Not that I mind, but really, beating 6 straight 1200ish players does not make me better than a 1450 player, because I've consistently struggled to beat those 1450 players lately.  Seems like a gap in the system.  Not sure how to correct for it.

    I do challenge myself to play better players, but during the tournament I've got this batch of 1200ish players, so its throwing my rating off.  Personally, my goal is for my rating to be less than the average rating of my opponents - that's how I'll know when my rating is meaningful.  Because if my rating is higher than the average rating of my opponents, that means I haven't been taking enough challenges.  Perhaps there's a way to factor average opponent rating into your rating.  Because if you keep getting +10 when you beat a 1200 player, could you get to 2000 that way?
