Better than an engine: Leonardo Ljubicic (2/2)

by Martin Fischer
3/1/2016 – In the second part of his interview with ChessBase, Leonardo Ljubicic, winner of the 28th World Championship in Correspondence Chess, speaks about time-trouble in correspondence chess, strong grandmasters in over-the-board chess who also excel in correspondence chess, the importance of opening preparation, and his chances against Magnus Carlsen in a correspondence match.

Martin Fischer: You mentioned that time-trouble was your biggest problem in over-the-board chess. How do you manage your time in correspondence chess? And is there really such a thing as time-trouble in correspondence chess – when you have 50 days for every ten moves?

Leonardo Ljubicic: On average, from Monday to Friday I spend about two or three hours on correspondence chess, but on Saturday and Sunday five or six hours are the rule. You need silence and concentration and entering the world of chess has become a great anti-stress therapy for me. My family has been most understanding and I dedicate my title to them.

But yes, amazingly, there is time-trouble in correspondence chess! If you overdo it and start too many games at the same time, either your performance will suffer or you won’t have enough time. You should choose your battles carefully!

Recently, there has been a new trend in OTB-chess: Many top-players – most notably World Champion Magnus Carlsen – do rely less on opening preparation and do not try to outprepare their opponents. Instead, they are happy to reach a playable position from the opening and then try to outplay their opponents later. Does such an approach work in correspondence chess? And how important is opening preparation in general?

Well, occasionally I come across grumpy comments from some players who complain that “today everyone can play chess by memorising lines and analysing with engines”. But I think the process you describe is a natural response to the fact that the opening nowadays is explored better and better and that theory expands all the time. Because “better” players feel that they have more chances to outplay their opponents in “unexplored” territory they tend to steer away from theory.

However, opening preparation is – at least the way I practise and understand it – of utmost importance in correspondence chess. I do not prepare for a particular tournament, but for each and every single opponent of mine and this preparation begins long before the game. I first try to get hold of as many of his games as possible which I then sort according to openings by preparing two opening trees: myopponent_white.ctg and myopponent_black.ctg.

Then I look at the games in detail, while keeping in mind that most good CC-players get better with time. I try to find weak spots in their repertoire (which are rather rare today) and try to guess whether there is a realistic chance to exploit these weaknesses. Will they really play a particular opening or will they try to spring a surprise on me?

Such serious opening preparation was the basis of my wins against Papenin and Straka in the 28th World Championship. I annotated the game against Straka in the first part of the interview but here’s the game against Papenin:

Nikolai is an International Master in OTB-chess and took up CC relatively recently. But he quickly became very strong. However, after taking our world by storm and topping the rating-list with an unbelievable rating of 2741 points, he started to show signs of superficiality - the last years he seems to be playing on inertia. I've already defeated him twice in that period, and now faced him again. But how to defeat an opponent which is both very strong and in bad form? I decided to 1. go for complex positions, 2. avoid long drawish lines with simplifications, 3. surprise him in his own yard (that is, with his own openings). After a lengthy analysis of his repertoire I found an interesting novelty which I thought might surprise him. 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Be7 6.Re1 b5 7.Bb3 0-0 8.c3 I was slightly worried of the Marshall (8...d5) here, but he opted for d6 9.h3 Nb8 10.d4 Nbd7 11.c4!? Leaving the well-trodden theoretical paths. c6 12.a3!? Following the strategy that started with 11.c4!?. exd4 13.Nxd4 Ne5 14.Bf4 Qb6 15.cxb5 axb5 16.Nc3 Re8 In this position I decided to spring a novelty on him: 17.Be3!?N With this move White chases Black's queen from the diagonal g1-a7 which helps him to play the thematic push f4. In fact, compared to the stem game White is effectively a tempo up. The stem game continued with 17.Bg3 Bd7 18.f4 Ng6 19.Kh1= The engines recommend 17.Nf3 but with this move White does not achieve much. 17...Qb7 18.f4 Nc4?! This pattern continued till the end of the game – Nikolai played seemingly solid moves that, however, were every now and then slightly suboptimal - a textbook example of how not to play top ICCF games. Better was 18...Ng6 though this admits that things have gone wrong and that the position is somewhat awkward for Black. After 19.Nf3 White has a strong position. 19.Bf2 Bd8 20.Bxc4 bxc4 21.e5 dxe5 22.fxe5 Nd5 23.Ne4 Be7?! Again, slightly inaccurate. Better practical chances offered 23...Qxb2 24.Nxc6 Be6 25.Nd6 Rf8 26.Nxd8 Rfxd8 27.Nxc4 Black is a pawn down but he has drawing chances. 24.Qc1 c5 25.Nf3 Qb5 26.Qd2 Be6 27.Nd6 Bxd6 28.exd6 h6 29.Rac1 Reb8 30.Rc2 Black's position is very difficult and maybe even lost already. Black must play with utmost precision and constantly evaluate whether simplifications lead to a winning endgame for White - but fortunately for me, my opponent kept making small mistakes, easing my task. Ra6 31.Bg3 Nf6?! A better try was 31...Qb3 32.Qf2 c3 32.Qf2 Rd8 33.Be5 Ne8 34.Rd2 c3 A bit too late. 35.bxc3 Qb6? After this inaccuracy Black is definitely lost. After 35...Rxa3 36.Nh4 Qd7 37.Qxc5 Qa7 with an exchange of queens Black could still fight. 36.Nh4 c4 37.Rd4 Ra5 38.Kh2 Rd5 39.Nf3 Rxd4 40.Nxd4 f6 41.Qf3 fxe5 42.Nxe6 Rxd6 43.Qf8+ Kh7 44.Qf5+ Kg8 45.Rxe5 Qb8 46.Qf8+ Kh7 47.Nf4 Rf6 48.Qxe8 Simplifying into a won rook ending Qxe8 49.Rxe8 Rxf4 50.a4 h5 51.Re5 h4 52.Rg5 1–0

In general, I try to play “healthy” openings – openings that have not been analysed to death and offer White realistic chances to get an advantage. With Black, I restrain myself to extremely safe lines that still offer winning chances should White go wrong. I do not understand how one can just play for a draw though I know that at the level of today’s correspondence chess you often have no other option with Black.

You play correspondence chess and you have a general interest in chess. Do you read chess books and do you follow top tournaments on the internet?

Correspondence chess, work and family hardly leave time to study chess in a more general way. But in my youth I enjoyed studying chess very much. Two books were particular favourites of mine: Modern Opening Theory by Drazen Marović (which I read in Croatian) and B.A. Zlotnik’s Types of Positions in Middlegame (which I read in Russian). I also regularly followed the British magazine Chess, the Russian magazine Skakhmatny, and our Croatian Šahovski Glasnik. And let us not forget the “Chess Informants”: for me, every issue was pure gold.

Today, I sometimes follow live-broadcasts on the internet, in particular if my brother-in-law is playing (my sister married GM Robert Zelčić). But if I follow these games with an engine running, I do get frustrated about the “erratic” play.

In an article published a few months ago correspondence chess GM Arno Nickel proposed new rules for correspondence chess to avoid the “draw-death” of the game. In the final of the 28th championship about 87.5 percent of the games ended in a draw. What do you think – are the many draws a threat to correspondence chess and does correspondence chess need new rules?

I read Arno’s proposal thoroughly. He is one of ICCF’s best and I have great respect for him, but I do not see his proposal as a solution to the problem of too many draws. He basically proposes to change certain scoring rules but this would mean to change some of the basic goals of the game. In my view this is not true chess. Perhaps an interesting variation, but not chess any more. Incidentally, I feel the same about Chess960.

I admit though that my position here is neither very constructive nor optimistic. I think we are indeed getting closer to the point when chess is solved (at least in today’s top correspondence chess). But this is what we correspondence players do – we try to solve chess by searching for the best moves and by expecting the greatest resistance from our opponents. This is different to over-the-board chess which is essentially mental wrestling. However, we reached our “goal” of solving chess much faster than expected. Now, we should face the truth and learn to accept it. And ask ourselves “what to do next?” (when chess is solved).

I checked the FIDE-ratings of the players who played in the 28th World Championship of Correspondence Chess. Seven players are unrated and the other ten players have an average rating of about 2120. Correspondence chess obviously requires different skills than over-the-board play. But do you benefit from Correspondence Chess in over-the-board chess?

It might be different for my colleagues, but my OTB-chess suffered when I got more and more involved in correspondence chess. In OTB-chess I was twice (1980, 1981) U15 county champion and in my twenties I became a Candidate Master. My FIDE-rating peaked at 2230 and I once defeated IM Branko Rogulj in the Open Croatian Championship in 1993 with black in 25 moves, probably the highlight of my over-the-board career.

So, while I was not exactly a rising star, I do have a decent chess foundation. However, intensive use of engines in correspondence chess did affect my abilities to conduct OTB-games. I overlooked simple tactics and in zeitnot I was weak and slow. My strategical abilities, on the other hand, got better and analysing with engines made me consider much more candidate moves. This process is very much like being handicapped in life: if your vision is hampered, other senses are sharpened. I stopped playing OTB-chess almost completely two decades ago. I do play a game or two per year for my club if they miss a player for league matches, but I lose almost every game “after achieving very promising positions”.

A number of great OTB-players also played Correspondence Chess, e.g. Paul Keres. And some of the Correspondence Chess World Champions have also been quite good in OTB-chess, e.g. O’Kelly, Ragozin, or Purdy. In recent years Swedish Grandmaster Ulf Andersson has been playing correspondence chess with some success. But do you know current top OTB-players (with a FIDE-rating of, let’s say, 2650 or more) which are good correspondence players?

Paul Keres

In fact, several strong OTB-players now play at the ICCF. I believe the most prominent is Indian GM Krishnan Sasikiran (2680+). However, I do not think there are many more who are that strong in OTB-chess. There are quite a few players with a rating of 2400 to 2550, though. Recently Croatian GM Bogdan Lalić joined the ICCF and started playing in the finals of the Croatian Championship.

You are trying to make correspondence chess more popular in Croatia. What goals do you have?

Two of my colleagues and I want to revitalize the CC scene in our country, as it suffered a serious crisis after our former CCA-President fell ill and had been inactive for several years. So far, we’ve been quite successful, gaining 20 odd new members, restarting a cycle of national championship tournaments, as well as beginners’ promo tournaments. All of our members are also very active in ICCF tournaments. And we have attracted strong OTB-players: apart from GM Lalić whom I have already mentioned above, IM Darko Feletar IM Nenad Dorić are also both very active, gaining ratings and experience fast.

I accepted to become ICCF National Delegate for Croatia and this puts additional pressure on my already tight schedule – my job is to handle contacts with the ICCF, to coordinate competitions and members, and to maintain our website (http://hrklubds.blogspot.hr/). Very demanding and time consuming. But luckily the ICCF officials are very motivated and always ready to help which makes my life much easier.

I hope that one day I will be able to let new and motivated members take over.

Do you believe that the abilities you need in Correspondence Chess are useful in everyday life?

Perhaps not in everyday life, but some of the abilities I gained playing CC have definitely helped me in my business career: seeing the big picture, project managing, sound logic, etc.

Chessplayers like to speculate how top players of the past would fare in today’s tournaments. However, I would like to know whether you think you would be a favourite if you played correspondence chess against Magnus Carlsen?

In a two-game match, I’d say the chances would be about equal but only if Magnus devoted a couple of hours to each of his moves. Anything less and I would be a strong favourite.

Thank you for your time, your insights, and the interview!
