Of course this is a massive redouble for money. It's not quite a
three-roll position, but it turns out to be a pass for money.
At this score, however, it's a different story. Even if it were
a pure three-roll position, it would be NRD/T. With a pure three-
roll position, 5/6 of the time, O rolls non-doublets, which
loses X's market if X doesn't redouble now. With so many market
losers, you might think it would have to be a redouble, but X gains
hardly any MWC by redoubling; if he redoubles now, then he winds up
with 86% MWC in such situations (or 100% if he is lucky enough to
roll doublets immediately), but if he doesn't redouble the he
just cashes, for 84% MWC. By contrast, if he rolls non-doublets
and O rolls doublets, then he will massively regret redoubling.
