Absolutely GREAT - that´s now again a new record (at least for search depth)!

Very interesting, that Chest was rather ´slow´ up to depth 22,
so I first couldn´t believe it would ever reach 62 -
but then Chest seemed to switch on its ´turbo mode´ ;-)
and showed a dramatic speedup in the finish!

Many thanks for this fantastic position, :-)
best regards,
Franz.
