Pass, 4spade} = pass or correct ! (4spade,4spade,4spade), {4spade} =bid: (4spade,4spade,4spade=spadeorspade), Slab (= asking where side King?)
there are (strong) hand where you can not see the closed suit, therefore above rule. Called SES (Special End Signal, but if suit fits to partner afterwards he can go further !)

(if you want to compare the 2 opening 6-11 after Pass)

Examples of the SES (Special End Signal): used when there is a possibilty that you can not see which suit is closed, So the normal endsignal 4 = now forcing and 4spade is pass or correct. Other bid is Slab which means: I know your suit (SLem Asking Bid) and asking for indicated side value. ( I know with a void in partners closed suit and you want to play your 'own' 4M , it can't be bid, So it is...)

An other instrument after the 3 no side Queen or King or the 3 with side value
is the
