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.

After a take it is an automatic redouble with the match on the line for
both, so the take point for her is about 15 per cent and my cash point
is 85 per cent.

Isight method gives 12 versus 7 + 1 (for the gap on 4) + 2 (for the
stack on 1) adjusted pips and an estimated winning chance for the game
of

80 - 12/3 + (10 - 12)*2 = 72 per cent

This seems to be too far away from my cash point, so it is ND/T for me.

Best regards

Axel
