I agree with you, in that it does increase depth, but he is entitled to his opinion.
However, how informed is his decision? Is he a regular Shogi player... does his book mention any thing about that? His opinion is only as valuable as it is informed.
Dixi.
I have to admit that this thread is a bit of a troll...
but I just read this comment by Edward Lasker in his book The Adventure of Chess (1959), and it upset me:
"Japanese chess...has certain curious peculiarities the origin of which has never been traced. One of them is the right of the player to place any captured man on any unoccupied square, instead of moving a man of his own. The man thus replaced on the board joins the army of his former opponent. This makes a capture doubly valuable. On the other hand, it introduces a tremendous complication without increasing the depth of the game."
Do you think Lasker was right about "complication without increased depth"?
