It is even worse than it looks.  I have never been able to score even a
single quarter point (the loser gets a quarter of a point in the case of
stalemate) against Scatha, and most of the time I am behind in material
before move 20.  I hoped my new "Scatha Brute Force" engine (which
uses plain PVS without null-move or other pruning) would be less
invincible, but it turns out that I hardly notice any difference (except
the displayed search depth).

I am beginning to suspect that hexagonal chess is a fundamentally
more difficult game for humans than rectangular chess.  The chess
pieces (except for the bishop) are more powerful on the hexagonal
board, which results in a much bigger number of complex tactical
motifs, mating patterns, and the like.   The sheer number and
complexity of the patterns makes them difficult to recognize
and remember.  It feels like I lose to an entirely new type of
tactical shot in every single game (except when I just make an
elementary blunder, which is also not unusual).
