  In 1998, Ciucu published "No-feedback card guessing for dovetail shuffles",
an article which gives the optimal guessing strategy for $n$ cards ($n$ even)
after $k$ riffle shuffles whenever $k>2\log_{2}\left(n\right)$. We discuss in
this article the optimal guessing strategy and the asymptotic (in $n$) expected
number of correct guesses for any fixed $k\geq1$. This complements the work
achieved two decades ago by Ciucu.
