Bid 4♠ with:
♠A Q 10 7 6 ♥A K J ♦2 ♣A J 6 5.
After 1♠-3♣/3♦/3♥
You must know what responder is
showing. Most play responder's jump
shifts as weak. If responder is weak,
opener usually passes. Opener can
raise with support (preemptively),
bid a new suit (forcing and looking for
game), or bid game. Some might use
a convention such as Bergen raises,
which changes everything. Also, if you
play strong jump shift responses, that
also changes everything written above.
My personal preference is to play these
jumps to a lower-ranking suit on the
three level as showing six or more
cards, natural and invitational.
After 1♠-2NT
You must know what responder is
showing. Many players (even newer
ones) use 2NT as a conventional response. If it shows a four-card gameforcing raise (Jacoby 2NT), then you
must study the follow-ups to that
convention (typically three of a new
suit is shortness; jumps to 4♠ are
flat minimums). If you play the 2NT
response as natural, all follow-ups are
natural.
After 1♠-3♠
Responder shows 11-12 points in
support and usually a four-card raise
(unless you play a special convention).
With a minimum, opener will likely
pass (though with a singleton or void,
he should go to game).

Pass with these:
♠A 6 5 3 2 ♥Q 8 3 ♦A J 2 ♣J 2
♠A Q J 6 5 ♥K 8 2 ♦J 3 2 ♣Q 4.
A bid of a new suit would show slam
interest (and typically the ace or king
in that suit). A raise to 4♠ is a signoff.
Bid 4♠ with these:
♠A Q 8 7 5 ♥7 ♦K Q 7 6 ♣J 10 2
♠A K J 8 7 ♥A Q J 2 ♦3 2 ♣3 2.
After 1♠-3NT
Assuming this shows 13-15 balanced, opener will usually pass. However, don't think of 3NT as a "closeout
bid." It simply shows 13-15 points. If
opener has slam interest, he shouldn't
pass. If the bid conventionally shows
a 4-3-3-3 pattern, opener would go
back to spades if he has a singleton or
void.
After 1♠-4♣/4♦/4♥
If both partners know this is a
splinter bid (showing shortness in the
suit jumped into, at least four trumps
and enough values for game), opener
can either sign off in 4♠ or look for
slam. Be especially careful here about
1♠-4♥. If one of you thinks this is
a splinter bid, but the other thinks it
is natural, the result could be catastrophic.
After 1♠-4♠
This is a weak bid typically showing
a five-card raise with less than invitational values, so opener will almost
always pass.
