Did you notice that RHO has just passed a forcing bid? I'd want to know what hand-types the forcing notrump contains, and whether this partnership has any previous experience of passing it, so as to gauge the liklihood that RHO has psyched. Yes, I did notice RHO passed a forcing bid but I also noticed partner's a passed hand who also passed the 1NT. The OP stated that 1NT was 'intended' as Forcing for 1 round with no extra information so I'm assuming that the opps are not a frequent partnership and maybe RHO is more accustomed to 'forcing, but I can pass with a min with 5332' or alike and LHO didn't know about it? Or was I supposed to ask that first? In any event, I play X as takeout in either of mine or partner's seat, so that's certainly out for me.
