    Chess Tactics Server

    Has anyone here tried the Chess Tactics Server at http://chess.emrald.net/index.php

    A lot of fun.
    And a lot of debate as to whether or not it's useful!

    I think it is.

    I see that it rates the tactitians by using the Glicko rating system

    Yes, it is the best. if you go to :http://dk-transformation.blogspot.com/
    from there, you can link to MANY members as they discuss their chess improvement, focused on chess tactical server. both temposchlucker and wormwood is there, as is myself. lot of knowledge and general context you won't find here. from the message board at CTS today, i found this site, and am going to take SpaceCowboy's advise, but have not yet found the large post he hints at, but anxious to get a comment up, to see if this activates my profile, if you dont mind, pls. thx, david

    In the past 3 months my tactical ability and rating have climbed--on FICS, from 1325 to 1725. CTS and Polgar's 5334 are great tools. I only do 50 problems per day but I do them consistently, aim for accuracy before speed, and review the ones I miss several times. Of course, playing chess daily also helps, and I suspect the jump from 1725 to 2000 will be harder!

    Chess Tactics Server is a great site.
    Concentrate on accuracy and don't get caught up in the speed trap.
    Problems range from dead simple to complex, which is what we find in our games, so it is ideal for us below GM status players .
    Not sure at what level it would cease to be of benefit, but even GM's say that revising the basics is good practise for them, so it can't hurt us.

    Advancing Chess Tactical Server!

    Advancing Chess Tactical Server!

    Advancing Chess Tactical Server
    It seems like news has been everywhere: Tempo's 1600+ and Tempo's 1616 most impressive record high well after the notable 50,000, Spacecowboys 1474 after his 20,000, Wormwoods recent freshly minted 1533 (yowww!)after vigorously piercing 50,000 also, lots of interesting chat on the CTS message board about burning lots of problems into memory, and Markusgoths recent 25,000. It really a daily work crowd deep in the night, like coal miners with lanterns on their head, digging deep into the earth, or in this case: chess, chess tactics, chess improvmenet, then lastly getting on line and beating somebody good who expects to take easy points for our rating, but we just did, well, we just did like 5,000 problems since our last game? Sound familiar to anyone??

    Then my particular crowd paralleling much of the above: the etheric high percent crowd among those over 15,000 problems who are rated 1500 or above, ranked by tries: Tempo again 80.7%, nabla (FM) 87.2%, Trallala 92.9%, kawala 83.8%, spacecowboy again 88.7%, morkovkin 89.1%, chessdog in the honorably mentioned (<1500) absolutely amazing 95.7%, dktransform 83.8%, and alvis honorably mentioned (<15,000) at 88.3%.

    I ask you chess.emrald.net users to go to the tactician tables and sort the top 51 active users by 'tries' and visually scan, asking yourself how many large users have done much over 83%? Nine persons.

    I surveyed this by counting the number of users by percentage success only for sets of persons 60 to 61%, 62 to 63%, all the way up to 98%. I made sets of sets of those (I was VERY curious), then supersets, to simplify the core observation, and found the following (data from ten days ago):

    60 to 63%= 137 users
    64 to 67%= 154 users
    68 to 71%= 157 users
    72 to 75%= 178 users
    76 to 79%= 146 users
    80 to 83%= 127 users
    84 to 87%= 098 users
    88 to 91%= 041 users
    92 to 95%= 024 users
    96 to 98%= 004 users

    If we look closely at chasing crowd at the "Hillary Step" (at Mount Everest in late May, their can be literally a log jamb of climbers waiting to pass at 200' below the summit, since their is so little room to pass) at the clump or cluster between 82 to 86% (85.0% is absolute my goal for 25,000), we find something quite interesting:

    82%= 30
    83%= 33
    84%= 41*!*
    85%= 23
    86%= 18, etc.

    In nature or complex adaptive systems, we often find other examples of 'buffering': sea tempuratures that make sudden jumbs, buffering between alkalai or acid states (I am not a chemist so please forgive errors of exact concept on this one). Why this hear?

    This takes me to my subject: I decided at 15,442 or 83.577% to go for 85.0 by 25k, and reversed engineered that I needed 87.183% for 9558 problems= 25,000.

    Now the facts, making spacecowboys and trallalas and even chessdogs fine accomplishments all the more poingent: I had gotten used to putting it my mind: "Ok, every sixth one I can err or have errors on". 1:4=75%, 1:5=80%, 1:6=83.33%, 1:7= (natural sequence of 14, 28, 56 then repeats) 85.7144% or 85.72%, 1:8=87.5%, 1:9=88.9%, 1:10=90%, 1:11=90.9%, 1:12=91.33%, 1:15=93.4%, 1:20=95%.

    It is very, very hard to avoid missing only one problem in seven, harder at eight. We all get those 1:10 runs where we get one wrong out of 20, then two in a row wrong, to get 3failed, 27 success=30 total. Then the bad days...

    Since this decision, I have done:
    12/126=138 (91.3%) Wednesday
    21/147=168 (87.5%) Thursday
    15/113=128 (88.3%) Friday
    02/042=44 (95.4%) Saturday [1500.3 ... I tend to speed up when and if I go <15,>1520.

    It seems that in this clumping at 84% that is outlying data from the smooth sequence up from 60 to 79%, then down to 85%, we hit this natural resistence at 85%. And the rarety of it makes the desire of some of us % success folks who do not focus mainly on rating but more on accuracy (I am NOT suggesting that this is worth MORE, only to note this difference), makes our desire all that much stronger, since so few get there. Anyone who wishes to can try.

    Some days the brain is tired, the eyes weak, the board vision dim. So we must really hit 88 to 90% on good days for a hundred problems or more since the bad days come to, such as last week when I had a terrable day at 80.5%. One mans humble opinion, please.

    It's tough when you're on a long road and there are no mileposts.

    But I don't think it's worth noting every inch of progress. The back-forwards nature of it isn't important. Better to look at it in bigger chunks.


    I've been stuck for while. And I'm glad I haven't counted the times I've crossed 1500! CTS itself keeps track of your highest ever rating and when you reached it. Also the trophy list is good to look at.

    So ranking 41st on Success basis at 90% on 537 tries is a reasonable effort
    Being on dialup, I can't even dream of getting the rating up to the lofty heights you mention. (Wish they would adopt a timeseal program )
    But that is how I use CTS, try and do 20 or so problems in a session, and aim to get them right. Of course I still try and do it within their time constraints, but my internet connection robs me of 10-15 secs at times which is frustrating.

    Philwillb at chess tactical server, or CTS at chess.emarld.net is darn good! way to go. 90% is the bomb! Thank you for sharing

    One suggestion (if I may humbly suggest [I am only 1650 but do love to study], don't forget balance.

    I write extensively at my post, "Chess Improvement"

    (at blogger http://dk-transformation.blogspot.com/. I believe that I can show that I am able to make reasonable comments with care and respect for other persons without making a MESS of things:

    * some blitz with increment (so you don't wind up in a silly mouse race) such as 3/12 =3min 12 sec increm (this is 11 minutes. an average game of 38 moves is 10:36: five minutes is just too fast for now; and fifteen does NOT allow you to rapidly ramp up to get the experience you need, such as a thousand or more game to start). Review your mistakes each time, however briefly. Do NOT just hit start and begin a new game. Take a moment.

    * balance this with review of GM games. you can get some via pgn files, and view them in winBoard. If you really want to become a "real chess player", I CANNOT SUGGEST ANYTHING better than to not only learn to save, copy, and paste games simply into winBoard (chessBase.com has a competing commercial platform. winBoard is free shareware and will get you started handsomely), but to load the 62 simple, clean, eligant games by hand or manually into pgn of lovely and dear Irving Chernev's The Most Instructive Games of Chess Ever Played. His Logical Chess Move by Move is also quite good, but this first book ties together simple middle to endgame transitions in memorable form. If you load then review one game every four days, you can have it done in eight months. This will solidify anyones play from swashbuckling to more solid, well-knit play. The founations of Strategy and study as against Tactics and time pressure.

    * basic endings. Pandolphinis Endgame Course has a few errors, but as Florida Master and early pioneer in chess blogging, A.J. Goldsby aptly says, the book is great anyway. It is all there!

    * slower tactics. CT-Art is too advanced for you (yet), but my dear friend at blogger, Blue Devil raves about Chess Tactics for Beginners. I'm impressed.

    Looking forward to your future comments.

    FYI, if you or anyone else cares to post a comment at chess.emrald.net that I am not a bad guy but DO need an edit feature, and tell Tempo that what he said was not particularly gracious, I'd much appreciate that. Sad. I have been, I thought, gracious to him in private email including notifying him in early July--personally--within mintues of my discovering that the server was back up and running, and have writen him always constructivley here at blogger, wrote many nice comments to him at chess.emrald.net, and he says this to me in public when he could have done it privately? What punishment do I deserve? What have I done to deserve this?

    Its ten times better if someone else says it and asks the rancor at CTS to stop please, and I made an honest mistake that I am really sorry for. Sorry folks. Volunteers, please?

    Hei, I am Markus, a chess beginner who love chess tactics server--- it is a really good site for training chess tactics. Sadly I think its 10 seconds time control is too stringent.

    3-10 second time-limits

    The 3 to 10 second time-limit no longer bothers me.

    When you can see short tactics in less than 3 seconds, you become almost tactically blunder-proof and will punish just about every mistake your opponents make. Tactical intuition also works minor miracles when in time trouble.

    A strong tactical study plan should also include calculating long tactics. Based on your real-game results, you'll discover which area needs more focus.

    Post CTS percent accuracy calculation

    To dktransform:

    David, I was glad to learn from your blog that your head is feeling better.

    Have you noticed what I have noticed? I have recently noticed that my percent accuracy appears like it is being calculated differently on CTS than it has been calculated in the past. I have already climbed from 88.8% to 88.9% in what seems like less than one week! This would have been nearly impossible using the previous method of calulating percent accuracy. The previous method of calulating percent accuracy was to average the entire history of problems that the tactician has done on the CTS server. I suspect there is now a new CTS method of calculating the percent accuracy of each tactician which does not use the entire history of problems that the tactician has done on the server.

    careful and assiduous calculations on CTS percentage success

    dear phillip, spacecowboy:

    i cannot take any big titles at CTS, but one title i qualify for is maniacal tracking in morbid detail percentage success. since i lay out an array of circles, like you get in a school exam, each night, and fill in each problem solved with a 'circle' and each failed with an 'X', i know quite well my success, in sets of eight, then sixteen, twenty-four, thirty-two, then forty, then i relog in.

    if i am at 6f/44s=50tries, (or 6f/50 as wormstor prefers to represent at our respective blogs), then i will try extra hard to get zero wrong to go 6f/54s=60, and hit my haloed ninety percent, or more.

    when i am at 1512/13 as i was last night, i exchange, in a way, rating for more care, and so slow a tiny bit, finishing 1510.9. my algorythm for some time, is that as long as im above 1500, preferably above 1510 for some contingency, then i try to get as many correct as possible, exactly as you do so well, and thus push up my averages. as you know so well in your remarkably logical and heuristically individual way, this approaches real chess.

    1510 or 1540 does not matter to me, as long as i maintain a level that is respectable, for my skill, relative to myself. what matters to me is sustained accurate thinking, as you do better than 99% of all users there, except maybe my nemesis who we won't name, or trallala, and other names well known to you.

    if someone is a blitz specialist, as i am not, then 65 to 70% is ok. but if you play as i do 3/8 (3min/8 sec increment =8:20 for 40 moves, or 3/12 as i did for many years= 11 min for 40 moves), then such a pace as 85 to 92% is a more valid test. you might sit on your hands at times, surely not at every move, as you and i do at CTS, and find the right move, even if it takes 28 or 33 or even 43 seconds, without feeling silly. believe me, when i play, i see this care show up, and know when to whip out the moves, and when to pause.

    i am not sure of what you say about a new method. im more than willing to test it. if youve read any of my posts at blogger, then you know ive derived my percentage, such as when i am 83.947, then when i expect 83.9501+ look for the report back = 84.0% switched over from 83.9, so know quite well there.

    when and if i cross an integrer or decimal, then if shortly thereafter i cross back, again watch, so from 72 to 84%, have gotten to do this not only 130 times, but more like 250 times, since ive gone over and back several times.

    if i may please ask, what is your background? you used to be at blogger, but inactive there, despite worm, and tempo all over there, mousetraper, loomis, and now even me. wonderfull stuff. seen your comments. but, of course, recognize we cannot be all things to all persons.

    i hate to edit, so send this as is now, and wish you the best.

    warmly, david, from the pacific northwest usa, in seattle
