Just curious; not implying any of the bms are wrong... :)

These positions were the ones for which Larsen awarded the move played an ! or a !!.

Larsen is quite generous when it comes to exclamation marks. So beware that some of those ! or !! aren't quite right. Notheless the suite could be used to develop a Larsen personnality or just for fun.

As I just found this out from one of my backup, I can't remember if all those good moves were played by Larsen or if some of them could have been played by his opponents (from what I can vaguely recall, about 95% were played by Larsen, a very few by the opponents - but I'm not sure).

The new Crafty scored 89/165 single threaded at 30 sec per move on my laptop. Generally, stronger engines score better in the suite, but according to wikipedia: "Larsen was known as a deep thinking and highly imaginative player, more willing to try unorthodox ideas and to take more risks than most of his peers.", so there is room for surprising results ;-)

Enjoy!

Thanks!

I wish I have an article from the 70s, written by R. Calvo in the Spaniard magazine "Jaque" mocking the Larsen's style of annotating games. Hilarious. It was written as if Larsen annotated it. I remember GM Panno going over that article and the game and literally he was shedding tears of laughter.

Larsen was a truly unique player and extremely talented. I attended one of his lectures in Buenos Aires to a reduced number of attendants and it was very enjoyable to learn many of his insights into the game.

The following position has a duplicate solution
8/8/8/2k1K2p/2P4P/1p6/1P6/8 w - - bm Kf5; id "Larsen50.22"; c0 "Larsen-Gligoric, Moscow 1956";

[d]8/8/8/2k1K2p/2P4P/1p6/1P6/8 w - -

Kf4 is equally good (mate in 30 according to Gaviota). After Kxc4, the idea is to play Ke4. No really earth shattering by Larsen probably gave it (!!!) :-)

A lot more corrections coming.

There are format problems (e.g. spurious e.p. fields).
There are some wrong solutions.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

On the remaining 46 positions, I let analyze with the 3 best moves
10 seconds 6*4GHz
That confirms one solutions is correct : Larsen50.32 : Rg2!
Sometimes, the Larsen solution is close to the best move.
And sometimes there are better moves found by Stockfish.

Larsen in one word: optimism!

That sounds weird for computer chess, but psychology is a big part of OTB play at the higher levels from what I read. Judith Polgar once stated that at the top ten level, psychology is 70% of the game!

No surprise that Larsen found "his" solution as a !!! and not mentionning the alternative way!

I'm sure the chess lesson was truely great.

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.
