Opponents opened one of a suit

Your basic choice, other than pass, lies between 1NT, double and a suit overcall.  There are other bids which we shall come to in due course but first it is important to discuss the boundaries between these basic means of overcalling.

1NT overcall


suit overcall at the lowest level

Further options are:-

the 2NT overcall

cue-bid in the opponents’ suit

jump in a new suit

jump in the opponents’ suit

two-suited hands

overcalling in the protective seat following an opening bid by LHO and two passes in considered in the context of each category of overcall.

overcalling in fourth seat after LHO has opened, partner has passed and RHO has bid

is considered on its own page.
