Advanced Defence to 1NT Doubled & 4th Suit Forcing

Defence to 1NT Doubled If partner opens 1NT (12-14 HCP)
And opponents double Showing 15+ HCP If we are weak we need an escape Because 1NT* will be a disaster After the * our bids are natural So any 2 level bid shows 5 of the suit and is a weak take out But the strong hand becomes dummy

Some use exit transfers
Redouble (**) transfers to ‘s ‘s transfers to ‘s ‘s transfers to ‘s ‘s transfers to ‘s Opener then completes the transfer But often we will not have a 5 card suit There are other better methods The one we will look at is called Helmic

Helmic Defence to 1NT* This defence allows an escape with all weak hands except 4333 shape The 4333 shape occurs in theory 10.54% So, every 10th time partner opens 1NT and it is doubled you will have this shape hand But we can allow for this shape as well using a ‘forcing’ pass

Defence to 1NT doubled With 8+ HCP we are happy to play
We have at least half the HCP So we would pass the double With fewer than 8 HCP We can re-double Or bid a suit

Defence to 1NT doubled If we re-double It says ‘I have a 5 card suit’
If we bid a suit ‘I have 2 x 4 card suits’

Defence to 1NT doubled Partner opens 1NT RHO doubles What do we bid?
A Q T 8 Partner opens 1NT RHO doubles What do we bid? Pass We have 8HCP And a balance hand Happy to play Good luck partner! 7 3 K 7 6 3 J T 6

Defence to 1NT doubled Partner opens 1NT RHO doubles What do we bid?
** We have 4 HCP 1NT* is a disaster Partner will bid 2 To find out which is the 5 card suit And we bid 2  8 7 6 5 2 7 3 K 7 6 J T 6

With a 5 card suit Re-double the penalty * Opener relays by bidding 2
Then bid the 5 card suit Or Pass if it is ‘s You must do this if you have a 5 card suit and fewer than 8 HCP The weaker you are the more important it is to get out of NT

Defence to 1NT doubled Partner opens 1NT RHO doubles What do we bid?
2 We have 2 HCP This bid says I have 4 ‘s And 4 of a higher suit T 9 7 4 7 3 J 7 6 3 J T 6

With 2 x 4 card suits We will be happy to find a 4/3 fit
Bid the lower suit Opener Passes with 3 or more of the suit With only 2 of the suit Opener bids the next suit up NOT a higher 4 card suit Responder may only have 2 cards Then responder bids the 2nd 4 card suit Which is passed by opener Or responder passes if the next suit is it

Defence to 1NT doubled Partner opens 1NT RHO doubles What do we bid?
Pass We have 2 HCP This bid says I have either 4333 and weak Or 8+ HCP The Forcing Pass T 9 7 4 7 3 3 J 7 6 J T 6

The Forcing Pass Opener bids 1NT and RHO doubles Responder passes
Opener MUST re-double Responder then passes with 8+ HCP Now you are playing in game! Or bids 2 with 4333 shape and weak Opener bids the longest suit Which must be at least a 4/3 fit

Helmic defence to 1NT* If opponents double your 1NT bid
They are strong If you use the escape mechanism and they bid a suit Pass and let them play This is your best outcome Never try to bid on You will end up even deeper in the mire!

Helmic defence to 1NT* If you use Helmic and find a fit
And opponents then double again This is also for penalties Do NOT try to find another fit Or bid 2NT Things can only get worse And more painful! They will double whatever you bid The suit bid must be better than NT

Fourth Suit Forcing (FSF)
Technique to determine if a NT game is on When your side bid all 4 suits Last bid is above the 1 level There is enough for game e.g. 1 P 1 P 2 P 2 Why did responder not bid NT? The last bid says: ‘If you have stops in ‘s bid NT otherwise bid another suit.’

FSF Partner opens 1 You bid 2 Partner bids 2
You know there is enough for game But if partner has no ‘s NT could be dodgy So bid 2 Asking for stops K J Q 5 3 J 7 6 A Q J 7 6

FSF Only use this when you have enough for game Partner must Alert
Normally played as forcing to game Partner bids NT with a good stop (A or K) Or 2 smaller stops (QJx or JTxx) Very useful for avoiding bad NT contracts

FSF 1 Exception 1 P 1 P 1 P 1 The responder has a weak 2 suited hand and is trying to find a cheap way out If responder had enough for game and wanted to find a NT contract The FSF bid would be 2
