Once you make any limit bid eg opening 1NT or replying 2 ♥
to partner's 1♥ opener or opening any
sort of pre-empt.
DO NOT BID AGAIN as you said it all on your first bid UNLESS partner
invites you or forces you to bid again.
You should only ask for
Kings in a Blackwood sequence if all the Aces are in your partnership.
Asking for Kings now suggests you want to be in the Grand Slam and you
would only do that if all Aces are accounted for. If an Ace is missing
merely go to 5 of the agreed suit of 6 of the agreed suit.
ADVANCED TIP 480
If you open 3 of a suit you have seven
card suit and if you open weak 2 of a suit you show six
Do not make cowardly bids of 2 of a suit
with 7 card suit

seen people do, so called advanced players)
