over nat

Level 1 overcall is lead directing, level 2 overcall shows constructive opening strength, except the sequence (1m) - 2♣, when also weak 5 card suit with 9 HC is enough.

FOL's bids are transfers, when she bids from cue to transfer to INT's suit. The exception is a level 3 cue, which allways asks for ST. Other bids are natural.

Examples:

(1♥) - 1♠

our bids are natural, F1, cue bid shows support, 8+

(1♣) - 1♠

2♣/♦/♥ are transfers,

Following rules apply:

Bids of new suits are F1, NT bids are natural

Raises of INT's suit are competitive.

Jump shift shows 4 card fit and good 5 card suit 2T3H

Jump Cue bid shows 4 card fit, 9+ točk

If RE doubles, our RDBL promises A or K in INT' suit.

If RE bids naturally and we still have transfer available - system ON.

Examples for (1♦) - 1♠ - ?

(DBL)

RDBL = A or K in ♠

other = system on

(2♣)

DBL = 4 card ♥, tolerance for ♠

2♦ = transfer to ♥

2♥ = transfer to ♠, constructive

2♠ = preemptive

other = natural, NF

(2♦)

DBL = transfer to ♥

2♥ = transfer to ♠, constructive

2♠ = preemptive

other = natural, NF

(2♥)

DBL = transfer to ♠, constructive

2♠ = preemptive

other = natural, NF

Same applies for sequences (1x) - pass - (1/2y) - 2yz (both natural).

Examples for (1♦) - 1♠ - (1NT/2x) - ?

We assume the hand belongs to opps. Our bids are the same as above, except:

2♥ = promises 3 card ♠ support with Q or better (does not promise points).
