In go pieces are placed and never move, also pieces just sit where they are, they have no influence.
Now imagine a move like bishop on c1 to g5. Not only do you have to imagine a bishop on g5, you have to remove the bishop on c1. You also have to imagine its new line of influence (the h4-d8 diagonal) and take away its old line of influence (the a3-c1 diagonal).
You also have to now recognize the g file and 5th rank has a new piece blocking it, and the c file and 1st rank no longer has a piece blocking it.
This may not seem like much, but to imagine a chess position 4 moves ahead, potentially a LOT on the board has changed. Many new lines of influence, many files, ranks, and diagonals are now blocked / unblocked, and many pieces that may not even exist on the board anymore.
Interesting question I would think. I know none of you have a college degree in psychology or neuroscience, but hear me out:
Go is a game of calculation, so is chess. They are both a game of spatial logic if you put it another way. I have found by recently picking up go that I am able to calculate quite far (10-12 moves after a minute my chess is about 4-5 after a minute but that's because of the complexity of the pieces). I heard many people start with significantly weaker ability. I imagine if someone in go started with it then went to chess they would be surprised at the significantly reduced ability to see ahead. Or maybe it's the opposite and people are chess gods compared to that highly complex game.
What are your thoughts?
