In an individual competition everybody plays the same system all the time (even if you happen to play with your regular partner(s)).Therefore no announcing or alerting is necessary.

Opening 1NT = 12 to 14 points

In response to 1NT

No transfers 

2§response to 1NT is Stayman

2¨/©/ª = weak take out, ordering partner to pass          3©/ª = 5-card suit and points for game

2NT = 11 or 12 HCP, balanced

3§/¨ = strong and unbalanced with long suit.

Defence to 1NT.  Natural. Double is for penalties.

If the opposition double our 1NT, 2§ is not Stayman but is natural.

1NT overcall = 16-18 points with stopper(s) in opponent’s suit.

Responses as if partner had opened 1NT with points adjusted

Opening 2 bids.

2§ = strongest bid - game forcing (except 2§ - 2¨ - 2NT).  2¨ response = negative, <8 points.

2¨/©/ª = strong (8 playing tricks), forcing for one round. 2NT response = negative, <8 pts.

2NT = 20-22 HCP, balanced.  Responses. 3§ = Stayman. 3¨/©/ª = natural and forcing.

Defenceto pre-empts.  Double = take-out.

Doubles of suit bids by the opposition up to 4¨are for take-out except after a  penalty double by partner or if we have agreed a suit.

Jump overcalls are intermediate (6+ card suit, about 11 to 15 points)

Slam Conventions.   

Blackwood- 4NT asking for aces, then 5NT for kings

Gerber (4§for aces, 5§for kings) only immediately after an opening 1NT or 2NT

Cue bids, showing a control after suit is agreed,are permitted.

Otherconventions.      

4th suit forcing: If we have bid three suits naturally, a bid of the fourth suit is artificial and shows a good hand in the context of the bidding so far and orders partner to bid again. A NT bid then shows stopper(s) in the 4th suit.

NO OTHER CONVENTIONS ARE ALLOWED

Leads.

Standard leads:

Top of honour sequence, 4th highest from long broken suit headed by an honour(s), second highest from a poor suit.

Signals and Discards. 

On partner's lead: high to encourage, low to discourage.

When discarding: high to encourage, low to discourage (only 1st discard is significant).

On declarer's lead: low followed by high = odd number of cards in suit, high followed by low = even number of cards in the suit.
