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

Also, the pinning/unpinning moves feel a bit coincidental. The composer compensated for this by adding an introduction also involving the thematic pinning and a B-sac. An almost perfect achievement.

Surprisingly, it seems to be original. It is a pity that the study has BTM, 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} *
