The initiative

Older players will likely still remember the time when we could beat the best engines available. I never experienced that myself. I started to play regularly chess at the age of 14 and while I quickly improved, I never could catch up in the 90ties with the engines. From 2000 onward only topgrandmasters could still challenge a computer but around 2006 this also ended. After that the engines kept on improving at a steady pace. For an amateur it became increasingly difficult to detect the differences between the engines. Nowadays I see many chessplayers don't search anymore for the best engine and are satisfied with an engine of which they know that it can beat any human in the world.

It is indeed irrelevant to have the best of the best for just a blunder-check. Only a few will also try to discover the little nuances in a game. Today the top-engines have become so strong that they can find in the most complex positions very quickly the right track and beside can not only maintain an initiative stubbornly but also increase it methodically. Last summer I had multiple favorable positions in the Open Brasschaat of which I had no clue about what I should do. A first example is against the 15 year-old Marie Dgebuadze. After a small mistake of Marie I obtained a very nice position but then I didn't push through. The engine demonstrates with accurate play that I hesitated too long which allowed Marie to neutralize my initiative.

After fxg4 there is a hole on e4 and the h-line opens but white can't profit from it. Contrary black will be able to infiltrate via Qh4 and set up a dangerous attack on the f-file by doubling the rooks.)} (32... fxg4! 33. Qe4+ Kh8 34. hxg4 Rf8 35. Rf1 Qh4 36. f5 Rdf7 37.

Rdd8? {(It is more complicated but again fxg4 is very strong. )} (33... fxg4! 34. hxg4 Rf8 35. Be4 Qd8 36. Kh1 Rdf7 37. f5 exf5 38. gxf5 Rxf5 39. Bxf5) 34. Rg3? {(Also white doesn't play again the right move-order so first gxf5 is necessary.)} 34... Rc7? {(Indeed I don't dare to play fxg4 and I don't get any new chance afterwards.)} (34... fxg4! 35. Rxg4 (35. hxg4 Rf8 {(This menaces Rxf4 with a double attack of the knight on e2.)} 36. Re1 Rf7 37. Be4 Rcf8) 35... Nf5 36. Re1 Rd4 37. Be4 Rxc4) 35. gxf5 gxf5 36. Kh2 {(White is first on the g-file. A draw became inevitable which occurred 10 moves later by a perpetual check.)} 1/2-1/2

I couldn't achieve more than a draw at the end. However int he second example it went even more sore. If you check the rating of the 25 year-old Yago De Cuyper then you find out that I should win easily as +500 difference is a massive gap. Nevertheless during the game this wasn't the case at all. Again I get the upper-hand in the middlegame but also here I hesitate which allows my opponent to counter-attack. I was shocked especially when the engine showed me how a few moves were needed to convert my initiative into a clear advantage.

Rc7 Bh4+ 43. Qxh4) 38. Nef4 Qg7 39. Rc1 Qg5 40. Qxg5 Rxg5 41. Ne5 Rg7 42. Nxe6 Re7 43. Bxf5 {(White is 2 pawns up and also has the attack. My position is completely lost and I considered for several minutes resignation. How it is possible against somebody 500 points rated lower? How I won from this position is a miracle but not relevant for this article.)} 0-1

It was a miracle that I still won the final position but this has no relation with the initiative so would only digress us. More interesting is to check if there are some symptoms in my game which explain these failures. Why can't I maintain the initiative against these "weaker" players?

The question was raised to me if I don't practice sufficiently tactics. I did miss some hidden motives which caused me to not consider some moves. On the other hand at chess.com I maintain for some time already a 3100 rating which puts me at the top of the Belgian players so I don't think I am worse in tactics than others. I also got the advice to study more Dutch games so I get acquainted to common combinations in this opening. I have more than 20 years experience with the Dutch so I think that I can consider myself an expert in the Dutch. Therefore I do dare to claim that the examples shown are not standard at all.

No in both examples I hesitated to push my pawns on the king-side as there are always risks connected to it. I couldn't properly evaluate it so I chose to wait. Very often the apple falls from the tree by itself or you get a better and easier opportunity. In above games it didn't happen this time so I spoiled the advantage.

By the way I am definitely not the only one having this problem. Recently I was at the other side of the board sitting. The Belgian FM Roel Hamblok got a winning initiative in the interclub against me with a clever game-preparation but it wasn't trivial to convert it into a win. White hesitated to sacrifice any material and just chose normal developing moves which allowed me to fight back in the game.

Qd3?! {(After the game Roel told me that he made good usage of my blog. Not only had he read that I would probably play this line but he also learned to work with Leela. However to win this won position isn't easy as you need to sacrifice a piece on c5 for some long-term attack which isn't every-bodies cup of tea.)} (12. Nc5! bxc5 13. bxc5 Ka8 14. c4 Rb8 15.

Rfd1! h3!? 19. g3 c6 20. b5! +-) 15... Ka8 16.

C4 is more energetic.)} 17... g5 18. Ba6 Qc6?! {(The refined Qd7 is stronger.)} (18... Qd7! 19. Nac3!? Bxa6 20. Qxa6 Rg8! 21. Kh1 Bh6) 19.

Again Nb2 is the best chance still with the idea of a4.)} 21... Nd6 22. Nb2 Nc4 23. Nxc4 {(White offered a draw as he realized his advantage disappeared. However meanwhile I figured out that I could start to hope for more so I declined and continued the game.)} 0-1

I earlier warned in my article sacrificing for the dangers of it. You often are left empty handed when the attack doesn't win immediately. Correct sacrifices demand a high degree of precision to make them work. So I understand perfectly why Roel preferred to slowly build up his position instead of making some gambles. It did however let the initiative fade away.

The volatile character of an initiative only leaves a window of opportunity open for a limited time. Between 2300 and 2800 there is a big gap of playing strength. How you manage an initiative is definitely a key-element of it. Some books learn players to think out of the box and to look beyond the risks but likely talent has the final word.
