This is considered true for Go, where games in smaller boards (9x9) are viewed as almost only tactical, and complex strategy is said to emerge only in larger boards (19x19 and up).

Does this happen also with Draughts? There is some difference between Brazilian and Canadian variants other than game length?

The only thing I could find about the topic is this http://laatste.info/bb3/viewtopic.php?t=7817 where at some points it is said that

<< 4. 12x12 draughts is more complex than chess, and very tactical (is my impression; I lost all test games).
5. 14x14 draughts is more complex than Go, and very strategic (is my impression; I won a few test games). >>

I would say that there are three components that increase or decrease level of strategy in any draughts variant:
a) capturing directions;
b) board size;
c) amount of king privileges.
First of all, I would like to remind that there are many different jumping rules. Here, in lidraughts, we are playing variants where a simple checker can make jumps forwards and backwards. However, it should be noted that in variants where a simple checker can jump only forwards, the game becomes less tactical, but far more strategical. In these variants (like English, Italian, Spanish, Portuguese, Argentinian, Tanzanian, Czech, Thai etc.) a player can crown more simple checkers than in variants where jumping both forwards and backwards is allowed. As well, jumping forwards rule restricts number of good moves strategically, but not tactically: if a player makes random moves in these variants, he or she can't make good exchanges and, subsequently, must sacrifice one checker or more, which leads to struggles in endgames.
Secondly, larger board size leads to think about invasion into strategically significant squares. I believe each one can easily recognize that number of strategically significant squares on large boards is higher than on 8x8. As well, it should be noted that opposition at early endgame stage is less predictable on larger boards than on 8x8. As well, on larger boards we can easily differentiate opening phase, early middlegame, later middlegame, early endgame and final.
Thirdly, there are two types of kings in draughts variants: long range kings (with whom we are familiar in lidraughts) and short range kings, like in Italian and English draughts. The problem is that huge material advantage is necessary for winning king endgames in variants with long range kings, while, for example, in English draughts an extra checker in majority of cases is sufficient for a win. This feature, for example, make English and Italian draughts more strategical than Russian and Brazilian.
Besides, there are some national variants where long range king is restricted in jumping, and that makes these variants more strategical. In Thai draughts and Argentinian draughts a king is obliged to end both intermediate and final jump on square next to captured piece. Due to this particularity, the stronger side is always winning in "2 kings vs. 1 king" endgame, therefore, Thai and Argentinian draughts should be considered as more strategical than Russian and Brazilian.

Thanks for your answer, very interesting. I didn't consider the other components you mentioned; I guess the 10x10 boards is the most popular one because offers a good balance between tactics, strategy and game duration.

Hey kalnap where's your IM title on here??

Would you consider streaming on here I know there isn't much of an audience rn but if you upload them to youtube I know the U1500 team I am a part of at least half those players would watch your your streams if they were anywhere as instructive as your post just was.
