Posted by alberlie nsa-hitachi.com 2/28/2006 07:14:32 Play online chess	Subject: How to use Fritz Message: Hi, I would like to let Fritz analyze a certain position. So, I let him chew on it and make him give me the three highest rated variations. Let's assume, I did that for about 30min, thus getting a relatively reliable result. Now, I want him to look at the three hightest rated variations _after_ those primary three choices. Is there a way to tell Fritz to explicitely disregard all variations starting with 3. Nc3; Nd2 and 3. Be3? That's something I wondered on a number of other occasions as well - imagine a closed middle game position where Fritz stubbornly insists on moving Rab8 Rba8 etc. Is there a way to make him think of something else? greets, AA
Posted by cairo nsa-hitachi.com 2/28/2006 09:06:35 Play online chess	I Message: understand your question, but I'll suggest you use your chess-intuition, as you said yourself the program, is stubbornly insist on moving a certain move, you as a human know better :-)) However if you don't trust you own skills, perhaps you can create the desired position and analyse from there, but always use your own intuition and common sense for the game. Good chess ahead! Best wishes Cairo
Posted by wschmidt nsa-hitachi.com 2/28/2006 12:32:53 Play online chess	Alberlie, Message: It isn't clear to me why you don't just have Fritz display 6 sets of variations instead of 3 and then paste all 6 to the game. But if there's a twist here I don't understand, here's my suggestion. I don't of a way to tell Fritz to ignore a possible move as it is doing its analysis. However, you can accomplish the same thing by doing the following: Instead of having Fritz display just the first 3 best variations, have it display the first 6. Then, when you've let it run as long as you want, paste all the variations to the game. Then manually delete the first 3. Then run the analysis for the remaining 3 (variations 4-6) individually for the desired length of time. Again, if you're running Fritz for half an hour on six variations, I think that if you just paste those six into the game and look at the last three you'll have a pretty good analysis. I don't know if you'd gain that much more by doing those extra steps. Again, maybe I've missed a nuance in what you're trying to do though. ws ——— Fischer didn’t stoop to intimidation — Bobby Fischer had a formidable passion for chess. He was a fierce competitor who eagerly — if not hungrily — played offhand chess games in virtually any place at any time. He was also a seeker of truth, a profound scientist of the game. Edmar Mednis, the New York grandmaster who intensely analyzed games with Fischer during the 1962 Chess Olympiad, marveled at his teammate’s insistence on finding the one and only correct move. Fischer refused to play powerful, intimidating moves with hidden flaws even though he might win easily by such means. He recoiled at what he regarded as an essentially dishonest violation of true sportsmanship. Other top grandmasters didn't necessarily ...
Posted by alberlie nsa-hitachi.com 2/28/2006 13:02:31 Play online chess	Message: well, part of it is probably purely "academic" interest - if I can "control" something more than I do already, I'd like to know about it ;o) But there actually is a somewhat more relevant point to it: Fritz doesn't distribute it's calculation time evenly but based on the strenght of the variations. Obviously it's highly unlikely that sacing the queen on move two is going to create positional benefits that will justify the material loss in the long term. Therefore, candidate moves involving a queen sac are given very little calculation time (but they are given some, nonetheless). Therefore, in a position where there are a wide number of plausible moves, I would like to be able to cut down on the number of variations, thus making computing power available for the next candidate moves. But I guess it _is_ of somewhat "academical" interest... ——— U.S. College Student Makes a Stand at the World Cup — The Chess World Cup has been an important part of the world championship cycle since 2005. There was no guarantee, given the history of the World Chess Federation, that it would continue to play such an important role. But it has. Some things have changed in the last six years — namely, how many players qualify for the cycle’s next stage — but the chess event has been held consistently every other year, and there has been an ample prize fund (almost $1.3 million, after fees). The top three finishers from the current tournament, which started last Sunday in Russia, will be eligible for the Candidates Matches. The competition features 128 chess players, with some clear favorites like Sergey Karjakin of ...
Posted by wschmidt nsa-hitachi.com 2/28/2006 13:09:38 Play online chess	Ah, I see.... Message: I think the multi-step manual version is the way to go then. ws ——— British chess champion, Michael Adams, out of World Cup in second round — The $1.6m, 128-player World Cup now in progress in Siberia is a very strong chess event, packed with elite grandmasters. The world No5, Sergey Karjakin, is the top seed while the British chess champion, Michael Adams, was ranked only 21st. Adams, though, has an impressive record in global knock-outs. The Cornishman reached the semi-finals or final of the Fide world championships in 1997, 1999, 2000 and 2004, twice losing only narrowly to the reigning world chess champion, Vishy Anand. He also began the World Cup fresh from victories in Philadelphia, Sheffield and Los Angeles. Round one was a disaster for China, which lost seven of its nine entrants, and a highlight for ...
Posted by mattdw nsa-hitachi.com 2/28/2006 13:48:09 Play online chess	Message: While we are on the subject of fritz - is it actually possible to delete games in the database? Nothing happens when I try to delete them in mine so I have duplicates of every game I have played with and without analysis - and they aren't sorted chronologically...grr. ——— Back to school: Chess 101 — As schools across the area resume classes, it's time for a refresher to relearn what many of us already know, but all too often forget. Even strong chess Grandmasters can forget the basics and make silly mistakes. A few simple tips like king safety, maintaining active pieces and practicing patience can really help improve your play. King safety is an oft-overlooked concept. Back in the 1800s, all the top chess players played for checkmate from the first move. Sacrificing a pawn, a piece or more was quite common, all in an attempt to get at the opponent's king. Aggressive play was often rewarded with inaccurate defense, and many wins were what chess players call "brilliancies." As chess players became ...

As the film was made for a wide audience it was understandable that the director chose not to discuss Fischer's chess-playing too deeply. But the clarity of his style on the chessboard makes for a telling contrast with his life away from it. Over the next few weeks we are going to be looking at some of Fischer's chess games. Here Black's king and bishop stand well, but White still has irritating counterplay. How did Fischer keep control? RB: Over the chess board how many of us, if we're honest, would simply snatch the pawn on ...
Posted by thunker nsa-hitachi.com 2/28/2006 14:09:02 Play online chess	Just a note Message: The more lines, or variations, you select for Fritz to analyze, the slower it will run.
Posted by alberlie nsa-hitachi.com 2/28/2006 14:35:41 Play online chess	thunker... Message: that is exactly the reason why I would like to specify exactly which lines it should analyze. And a bit more specific than "the first six choices" or so. But apparently, this seems impossible. Maybe some other engine can do this?
Posted by mattdw nsa-hitachi.com 2/28/2006 14:57:43 Play online chess	Message: Thanks for the suggestion Thunker, but I couldn't get it to work. I'm running Fritz 9 but I haven't updated it yet though as it wont let me connect to the server due to firewalls.
Posted by wschmidt nsa-hitachi.com 2/28/2006 15:13:16 Play online chess	a clarification question.... Message: Thunker, when you say "The more lines, or variations, you select for Fritz to analyze, the slower it will run" are you saying that if I click on the "+" sign and increase the number of analysis lines displayed when Fritz is looking at a position, it will run slower? I've always thought that was simply a question of how much of Fritz's analysis was displayed on the screen since the engine has to rank its choices internally anyway. If that is not the case, I'll change my approach, because I often have several lines displayed just out of curiosity. ws
Posted by alberlie nsa-hitachi.com 2/28/2006 15:16:41 Play online chess	Message: It doesn't matter as long as you only have three or so displayed - but if you increase it to more, say six :o)) or so, it slows it down.
Posted by thunker nsa-hitachi.com 2/28/2006 15:42:13 Play online chess	wschmidt Message: I used to think it was fixed too until my teacher told me otherwise. I did a little test and going from 2 to 3 even slows it down a bit. I rarely use more than 2 if I want to do a deep analysis of a specific position in a past game. Of course, for quickie stuff more lines don't hurt a whole lot.
Posted by thunker nsa-hitachi.com 2/28/2006 15:44:22 Play online chess	alberlie Message: I have Shredder also but I think most all the ones that ChessBase has bought out pretty much run under the "Fritz" interface - only the engine itself is different. So I doubt any of the "ChessBase" backed ones won't do what you're wanting.... Don't know about any others...
Posted by dysfl nsa-hitachi.com 2/28/2006 15:52:04 Play online chess	My method Message: For mattdw's question, you can specify if you want to replace the existing game with the anlalyzed one or create a new one. I usually select replace. The exact field name might not be 'replace', but you will have no trouble to find it. Also, while you're reviewing the Fritz-commented game, you can add your own comments or delete unnessary lines, then 'ctrl-R' will replace (update) it. For Wschimidt's question, I think if you ask more variations by pressing '+', it will run slower and give you more deeper analysis on those top x variations. Try it yourself. I change the number of variations when I liked a specific variation but it was not in the top 5 after, say level 13. I press '+' several times and wait for the completion of level 13, sometimes it makes to the top 5. However, it should be noted that the numeric evaluation varies a little in each run.
