********** ----- Fritz and Rybka Chess Analysis Engines Forum ----- **********

Hi and welcome.

My name is Peter. I am a USCF Life Member.

I have been a USCF Delegate, TD and Certified Chess Coach.

I am in my mid 50s and love chess.

My love of chess is far greater than my ability OTB.

I've been back to the game for 5 years after a 30 year gap.

My wife and I are patrons of chess in our area.

Please help us create more chess for everyone.

This is my 12,000th post. I put it here as a tribute to all you have done for the site in general, as well as for the opportunities you have provided to me in particular.

Thank you.

Premium Chessgames Member
  morfishine: Hello <chesstoplay> I enjoyed your post (over at the main page of Williams vs WT) touching on playing GM's and running a retail chess store.
Premium Chessgames Member
  Robin Gitte: <chesstoplay> Your comment on my forum appreciated. Bravo.
Oct-20-13  DcGentle: <chesstoplay> I have to agree to <morfishine>, you are a real chess enthusiast and the game needs people like you in order to get more support in all its dimensions. It's not only sport, it's an art form like you said, and it even gives reason for scientific research.

Some kibitzers on this side deride certain GMs, I would never do this.

"Gens Una Sumus". This should not be the Fide motto only, all chess players have something in common: The love for the game.

  MarkFinan: Hi there! I just noticed this in your bio <<My love of chess is far greater than my ability OTB.

I've been back to the game for 5 years after a 30 year gap.>> and thought it's pretty similar to my story. 20yr gap and 3yr back. Just wandered if you have a rating still, because you also said you're a USCF Life *member* and I thought you must mean life master? Do you have a rating floor? The reason I ask is we have people here who call themselves life masters like it's a title as opposed to just being a member of a federation.

  MarkFinan: <<MarkFinan: Hi Peter. Nice to see you stop by here too, and thanks for sharing that story. I'm starting to think that everyone are Beatles fans now, lol. And 2000-2200 is really good, you must have stayed in chess in some capacity to maintain that kinda level of play, unlike me, I had a straight 20-23ish (bad memory! Not a good thing for a chess player lol ) year's of not playing, and have only been really getting into it all again these past couple of year. Well having friends who are grandmasters must be a great help if you're ever stuck with anything chess related.

I hope you're enjoying the WCC, I really want Carlsen to do it (which I'm sure he will now). I think he could overtake Kasparov as the G.O.A.T by his mid thirties, but in this day and age it's easy for a young man to be distracted by other things! As I know well.

Take care, and pop in whenever you feel. 😃


Im just reposting this here Peter, in case you thought I'm ignoring your post at my forum.

Nov-18-13  DcGentle: <chesstoplay>: Hi! Well, I just read your posting on the WT pages, and because I have decided, not to start a big fight about this move <18... d3> there, I'll comment here about it. It's a critical move, and several ways have been discovered how White might be able to produce a blockade after this move.

Superficially seen, after this move pawn d3 may look like a bone in the throat, as you say, but the truth is, it spoils Black's pawn structure, which otherwise would be suited to lock down the kingside and start a method of restricting White, repeating patterns of the last game.

<imag> has conceded that <3... d3> offers chances for White to draw by producing a blockade.

This could be avoided, would we take the white queen on the spot.

I don't know, what to do. A draw can still be avoided, but after <18... d3> I am skeptical.

Premium Chessgames Member
  chesstoplay: < DcGentle >, You did a great deal of excellent work.

With my players through the years, I have had similar struggles. I learned that their individual styles were not always malleable. Some players, for example, were Knight players no matter what the call of the board was for piece play to come. Others, the same, but they were for their Bishops.

Is your move good? Yes.

Is it one of a few good moves? Yes.

As long as the <World Team > enjoys the experience of this GM's kindness in playing us in this exhibition, it is all good.

Our undefeated record, at least, is certainly not in jeopardy!

Keep working as hard as you have been!

The team needs all key contributors!!


Premium Chessgames Member
  hms123: <DcGentle> Your work and effort are greatly appreciated.
Nov-18-13  DcGentle: Thank you for your support!

Sometimes it's a sad story, you know, I already mentioned this on the WT main pages, that people just cannot let go of a certain move, because the engine evals are the best. Only engines don't know anything about blockades. A group of teammates have figured the blockade positions after <18... d3> weeks ago, but then other came along "rediscovered" the move (due to good engine evals) and now it's in the lead of the voting.

It's a weakness of the team, that bad news about certain moves don't spread (members don't easily admit that they were not successful there) and so other options will not be regarded.

You know, it's not about <my> move, it's about the possibility to win the game or not. Theoretically <18... d3> offers some chances, I don't deny it, but in this special case Williams will have recognized the inherent blockade options, I am quite sure, he even took an extension for this.

Nov-18-13  DcGentle: By the way, here is a line that I already posted twice on the WT forum, but the feedback was meager:

[Event "Analysis World Team Game 2013"]
[Site "MyTown"]
[Date "2013.09.17"]

Interestingly the eval drops, because the engine has no clue what's going on. Objectively the knight doesn't improve its position, but it helps getting Black's rook out of the corner.>} 36.

He is in a state of mild Zugzwang, it doesn't really matter what he moves, Black cannot be stopped breaking through on the queenside.>} 45. Bg1 Kc6 46. Ra1 Rd8 47. Be3 b5 48. Nc3 Bxc3+ 49. Kxc3 b4+ 50. Kd2 Kb5 51. Ke2 c5 52. Kf3 Ra7 53. Bf2 Kc6 {<clearing square b5 for the knight.>} 54. Be3 Nd6 55. Rg6 Nb5 56. Kg3 Rdd7 57. Kf3 Na3 58. Rg2 a4 59. bxa4 Rxa4 60. Rag1 c4 61.

I know that not all moves are forced here, but essentially White has no chance, he cannot do anything.

On the other hand, after <18... d3> we must be lucky not to be confronted with a draw.

This forum is not hidden.

Nov-19-13  DcGentle: <hms123>: Thanks for the hint, but what I posted is old news anyways, because the move used in this line won't be played.

So no damage done, I guess.

Premium Chessgames Member
  hms123: <Peter>

I think you haven't checked the box that says <hide from chessforum activity>. It is last on the list.

Premium Chessgames Member
  hms123: <Peter> Much better.
Dec-02-13  DcGentle: Hi <chesstoplay>

This is it, what the team missed:

<The Power Of Pawn Chains>

DcGentle chessforum

Maybe I should post it on the WT pages, but it's too late anyways. But I had to write it down.

Jan-07-14  DcGentle: A belated <Happy New Year>, <chesstoplay> !

Something struck me today, which could be important for my planned chess engine, and I had to write an article: DcGentle chessforum

What do you think about it? Positional play is not easy, but Carlsen demonstrates that it's possible. And we had other masters before Carlsen, of course, Karpov, for example. But was either of them so brilliant?

Capablamca was good, and also Lasker. The latter was a mixture of positional player and tactical genius.

Even Kasparov was more of a tactical player, I guess.

What do you think?

Jan-11-14  DcGentle: <chesstoplay>: You are the soul of this site! Many thanks! :-)
Jun-14-14  DcGentle: <chesstoplay>: Well I saw you visibly pleased about the return of <RandomVisitor>, and I know why. His engines have been a great help to the team in the past, at least in the understanding of most members. But my view is, that the team has ripened in recent years, and perhaps you know that I am working on a new engine with a new paradigm. Is this necessary, you may ask. Yes, it is.

Look at this study (DcGentle chessforum), and you'll see that current engines don't "understand" positional play really. In the meanwhile I know why: Here (DcGentle chessforum) you can read, why current engines are materialistic and only want to win by material gain. This is not only a poor style, but can even miss winning chances. Against GM Naiditsch we'll have to improve <RV>'s engines' suggestions, I am quite sure. We were lucky last time, that our previous opponent didn't use his engines in the way we did, if he did use an engine at all. This time it will be different, most likely. The team has shown that it can do it, but not if everybody works alone.

My new engine shall play positinally, and not try to gain material come hell or high water. Positional play is often much more effective. I cannot claim it will play like Carlsen, but it will most likely often select different moves than the current chess software.

So currently I don't know, how much time I'll have to help with the soon to start analysis, I have to find a compromise, I cannot delay the work for the new engine for ever. Some things are still unclear with the algorithm, and especially here I have to make progress.

Anyways, I will watch the game and maybe contribute, if there are problems.


Jun-14-14  DcGentle: <chesstoplay> Hi again, I found two ebay links that might interest you regarding your Pattberg chess board:


Unfortunately these items are not available anymore, but it may pay off to watch ebay, whether there are new offers.

All the best,
