Can a 2 Preempt Open Bidder Bid Again
Every bridge histrion is familiar with preemptive bids but few apply them to great advantage. Preemptive bids might be described as the "great blaster" considering, no matter how adept your opponents are, they volition not be able to cope with every situation. And that is how to win at span — give your opponents a lot of problems.
This lesson applies non only to preemptive opening bids only as well to direct leap overcalls; for instance, if your correct-manus opponent opens with 1
No trouble. Double! 
In that case I have dorsum my double.
I recommend an ambitious use of preemptive bids. Don't wait for the classic hand; look for every opportunity. This strategy will make your bridge sessions less consistent; but in that location is no reward for consistency in duplicate span. A steady player who scores 55% every session will near never win; while the role player who alternates from 45% to 65% will win nearly one-half the time.
Universal Rule
A actor who makes a preemptive bid surrenders captaincy. Only his partner may instigate farther bidding for his side. In other words:
One time you preempt exercise not bid again unless partner bids — and fifty-fifty and so you should generally pass whatever nonforcing bid.

Playing Tricks
In guild to determine when and how loftier to preempt it is necessary to estimate how many tricks your hand will win if your long adapt is trumps. In some cases this requires merely mutual sense:
1.  |  K Q J ten 7 5 4 | 6 tricks |
| 8 3 2 | ||
 3 | ||
| 7 three |
Clearly you lot will win six tricks in your own hand if spades are trumps.
In other cases information technology requires a judge. The all-time procedure is to estimate how many tricks your honour cards will win, then:
Add one additional trick for each card over three in any suit.
| 2. | viii | 7 tricks |
| A Q 8 7 half dozen 4 two | ||
| Q 8 6 two | ||
| three |
You have two honor holdings to consider. The

Requirements
The point-count and accommodate-length requirements for a preemptive bid are rather flexible:
0 to x HCP — although with 10 HCP yous should prefer a ane-bid if your mitt qualifies.
At least a 6 carte suit — contrary to popular belief, a 7+ card suit is not required.
No side 4 card major Q-x-x-x or meliorate — note that this permits a weak 4 card major.
Vulnerability
The principal consideration before making a preemptive bid is the vulnerability. The traditional practice is to overbid two tricks vulnerable or three tricks nonvulnerable. This "rule of two and 3" is unproblematic, just it will non give your opponents many problems. The modernistic "dominion of 2, 3 and 4" is far more effective:
Overbid ii tricks at unfavorable vulnerability (vul. vs. non).
Overbid three tricks at equal vulnerability.
Overbid four tricks at favorable vulnerability (non vul. vs. vul.).
Permit's decide the correct opening bid for Examples 1-4 at each vulnerability situation:
1. Open 2
2. Open up 3
3. Pass at unfavorable or equal; open 3
iv. Pass at unfavorable; open three

Responses to Preempts
The greatest danger of a preemptive bid is not the bid itself but what an inexperienced thespian might do in responding. Pass is the fundamental word. Even with as many equally 15-16 points, it may be unwise to answer since partner has already overbid by 2, 3 or 4 tricks according to the vulnerability (which you know).
When responding to a preempt, think in terms of the tricks you tin can provide, not signal count.
| five. | |||
| Partner 3 | You lot Pass | A Q 9 6 ii K Q 6 3 Q J 9 2 | Both Vul |
Partner shows 6 tricks and your manus should provide 2, possibly 3. Do not commit the folly of bidding 3 NT as you lot will be unable to utilize partner'due south arrange for lack of entries. If the vulnerability were unfavorable, I would take a chance and bid four
| half-dozen. | |||
| Partner 3 | You lot 4 | 2 A Grand ten 5 3 A Q viii 2 Q 8 four | None Vul |
In that location is a good chance you lot can provide four tricks, enough for game opposite partner's 6. Note that you exercise not need trump support to raise a preempt. If the vulnerability were favorable, I would pass three
| seven. | |||
| Partner 3 | You Pass | 1000 J 7 vi 5 A Chiliad 8 5 3 — Q iii two | Whatsoever Vul |
Partner's bid is non what you wanted to hear, but the situation is likely to get worse if you bid. The best risk for a skilful score is to hope your left-hand opponent bids.
Winning Tip
When passing a preempt with a good hand, practice not give information technology abroad by huddling. If you lot laissez passer in tempo in that location is a meliorate adventure your left-mitt opponent will bid or double and become into trouble.
| viii. | |||
| Partner 3 | Y'all iv | K 8 ii 9 5 three A x 6 4 3 vii ii | Both Vul |
Here y'all do not expect to make iv
New Suit Response
Almost of the time y'all volition either pass or raise partner'due south preempt, merely it is too possible to bid a new suit. This requires 6+ cards, or a strong 5 cards at the three level. Further, y'all must be prepared for partner to bid again if your bid is not game.
A new arrange response below game is forcing by an unpassed paw.
| 9. | |||
| Partner 3 | You lot 3 | A Q 7 5 4 3 A iii 2 3 Yard 8 four | None Vul |
Your bid is forcing. Partner should raise to iv
| 10. | |||
| Partner 3 | You 3 | K Q J ix half dozen A K Q ix 8 2 8 2 | Both Vul |
With two strong suits this hand is worth bidding despite the potential misfit. If partner does non raise spades you will next bid 4
| 11. | |||
| Partner three | You lot 4 | 2 ten 3 ii A K J 8 7 6 nine vii 4 | None Vul |
Hither your bid is tactical. Yous are sure the opponents can brand 4
3 NT Response
Another possibility is to bid three NT over partner'due south minor-suit preempt (rare over a major). Generally, yous should have at to the lowest degree three cards or a doubleton award in partner's suit plus stoppers in the other suits.
Do not bid 3 NT with a singleton or void in partner's suit unless you lot wait to win nine tricks lonely.
| 12. | |||
| Partner 3 | Yous 3 NT | A Q 3 K J 9 6 two Grand three Q J 4 | Any Vul |
You lot hope to run partner's diamond arrange; A-Q-10-x-10-x-x would be nice, though you may succeed contrary lesser holdings.
| 13. | |||
| Partner 3 | You lot 3 NT | A 1000 9 3 A 10 2 9 7 2 A 8 3 | Any Vul |
You practise non take a diamond stopper, just 3 NT is the best hope for game (peculiarly at matchpoints). Even if partner has no help, the lead may not be a diamond or the opponents may cash only four tricks.

If Partner Has Passed
If your partner has passed (you are in third or fourth seat), there are a few additional considerations about preemptive opening bids:
A preempt at the level of game may contain more than than 10 HCP if a slam is unlikely.
A preempt in fourth-seat (after three passes) should contain 8+ HCP; else pass the bargain out.
