Openings
1C two-way (11-13 bal OR 17+ any shape) (It feels like about 5 to 1)
2D multi (wk M or 22 NT)
2H 4414 or 4405, 11-16. 
Responses: Jumps INV, 2NT FG ASK, step responses
2S both minors 4-5,5 losers. 5+D, 4+C, 12-16, no 4+M. 
Responses: 2NT=wk or FG relay.     3C=FG relay.
After 1C
ART 1D (0-7)
NF 1/2NT, 2 C/D, 3D/H
ART 2H(minors INV or 20+)
ART 2S(C INV+ or C+D FG)
ART 3C(=D FG)
ART 3S(xfer to 3NT 14+)
ART 4C/D(=good H/S)

After 1D:
NAT resp, but
1NT = 6-10 no 4+M, OR 16+ without jumpable suit. Opener uses xfers.
2NT = INV based on shape not points
2D=10-15

After 1M:
2C=relay, A:ART FG or B: NAT NF (if next bid 3C or raise of 6card M) 
Opener bids ART at 2-level and on later relays.
This relay is used by responder when he has no other 5+suit that he 
wants to show and/or finds it convenient to explore openerīs hand 
without showing his own (he may well have 4suit in oM).

Competitive bidding:
We use xfer methods after 1C (interference), and when opponents double 
our 1M (opening or interference). The xfer is used either to to show 
suit (to improve contract or to start constructive bidding) or to show 
values/suit with trump support.
