Aray - Free - hi both - in my view there is a minimum subset of common conventions that you can assume from an experienced partner. Conventions of such obvious worth, that no-one in their right mind would ignore them. Lebensohl and texas ( with/without interference ) being somewhere near the top. When you are not able to count on that minimum set of conventions/agreements - you are forced to make compromises - to make inferior bids. I would count 3S or 3H as unconditionally forcing to game - but if I am not sure that partner will do likewise - then i may feel compelled to select some inferior bid. Ciao - Joe
