Pinpoint Astro is a convention for use after the opponents open 1NT. It is a refinement of the Astro
convention. It is also nearly identical to Brozel
, except that Pinpoint Astro uses a double for penalty instead of showing a single-suited hand.
After the opponents open 1NT:
|Double || For penalties. See also: Gates Double.|
|2 || Shows clubs and hearts (at least 5-4 shape). Partner can pass with club tolerance, or correct to 2 with longer hearts. |
|2 || Shows diamonds and hearts (at least 5-4). |
|2 || Shows hearts and spades (at least 5-4).|
|2 || Shows spades and a minor (at least 5-4). Partner can pass with spade tolerance, or bid 2NT to ask for the minor suit.|
|2NT || Shows clubs and diamonds (at least 5-4, usually 5-5 or better). Partner should take his preference by replying 3 or 3.
Note that partner should always take the cheapest preference when holding equal length in the two advertised suits. For example, after hearing a 2NT overcall, partner should bid 3
with 3-3 shape in the minors.
If partner is lucky enough to hold game-invitational values or better, then he should raise or jump-bid any advertised suit.
Pinpoint Astro also includes bids to show 3-suited hands, e.g. 4441 or 5440 shape (rare). A jump overcall at the 3-level is artificial and indicates shortness in that suit:
|3 || Shows a 3-suiter short in clubs. |
|3 || Shows a 3-suiter short in diamonds. |
|3 || Shows a 3-suiter short in hearts. |
|3 || Shows a 3-suiter short in spades.|
Partner is expected to take a preference for whichever suit he likes most. Since he may be forced to take a preference at the 4-level, these overcalls should promise very good hands (relative to the HCP
range of the opponents' 1NT).
