Is it possible that the programmers have decided arbitrarily to convert 4 level contract to penalty merely because they do not think they can MAKE anything they bid
when partner makes a TOX --- the x is described as take out? This needs to be fixed and the computer should NEVER leave a tox in w/o defensive trump tricks (which they
will almost never have. That should solve these stupid (yes stupid) passes with no defense. If I am wrong to balance with this type of hand sobeit BUT the computer
should NEVER EVER convert any self described TOX w/o trump tricks PERIOD (well at least through the 5 level anyway).
