t thematic study. The thematic tries (except for the one on the first move,
which is only a try in this particular tourney) are really excellent because
the pinning/unpinning moves are a real festival including halfpins both as
"pinning" and unpinning moves. Also in the main line 7.d6 is an unpinning move,
but also a halfpin, and 8.d7 is a selfpin, with 8...Ke6 as an unpinning move.
All of it is crowned by a very natural excelsior. It must be said, however,
that this study lacks surprise, a prerequisite of studies in non-thematic
tourneys. But here I do not care. HvH}) 1-0

compensated for this by adding an introduction also involving the thematic

especially since this is not necessary at all! I would prefer the setting with
wRc8 instead of wRe8 and WTM (1.Qh3). The extra black move is hardly
interesting.  HvH} *
