Most important thing to know about shogi: It's only in 2 dimensions.

Everything else is just minor details.

Kind of dumb spending several chapters on this guy's motive only to reveal he's just the pawn of some mastermind
What was the point then, his reasons are irrelevant now

He had his own goals, and he's getting help from this other person. You can call them a mastermind or whatever, and they are probably the brains behind this, but this Yae guy would only do this stuff because he wants to, he's not just a minion.
