Support doubles and redoubles

Support dbl can only be bid by OP after:

- Level 1 opening

- RE bids 1M (transfer included)

- RHO lbids below 2M (naturally or artificially)

After 1♣ supp dbl shows unbalanced hand. If balanced and 11-13 we pass, with 17-19 we bid 1NT regardless of ST.

Even when these conditions are fullfilled, we do not bid supp dbl, if:

- we could better describe our hand otherwise

- we have tooo much strength in opp's suits- imamo defenziven list (malo A in K)

- RHO bid 1NT naturally

- we are too weak to play 2NT or above, if RE doesn't hold extras

Same goes for support rdbl.

After 1x - (pass) - 1M - (1/2y) - dbl  RE's answers are:

- NF up to 2M

- invitational above 2M

- Cue bid is GF
