Hi!
I am learning Polish Club and have some questions:

a.)
1♣ - 1♥/♠ -
jump shift* --> KCB for 6 Aces = 4 Aces + the 2 Kings in {M + jumpsuit}

*2♠ after1♥/3♦/(3♥ after 1♠)

With which kind of hand do I do it? Is a double fit implied?
We have also the sequence
1♣ - 1♥/♠ -
2♦ = strong, at least Hxx to partner's suit, asking for length + quality in bid major.
So there must be a good reason for distinguishing.... I guess that opener has a real rock when jumpshifting, or?

b.) OMEGA = reverse rebid or jump-shift in minor after positive response --> asks for fit in opener's suit and controls (A = 2, K = 1):

1♣ - 1♠ -
2♦/♥ or

1♣ - 1NT -
2♦/♥/♠

c.)
1♣ - 1♥/♠/1NT -
3♣ what does this sequence show? Is this a jump-shift?

d.) Has opener after
1♣ - 1♥/♠ -
2NT
the balanced 18-20 hand?

e.) What is
1♣ - 1♥/♠ -
3NT ?

Thx!!

1♣ - 1♥/♠ -
jump shift* --> KCB for 6 Aces = 4 Aces + the 2 Kings in {M + jumpsuit}

This is not WJ2005. The auction 1♣ 1♥ 2♠ is described as 6+ good Spades. Same with other jump shifts, 1♣ 1♥ 3♦ should be the same, but hands with only 5♦ or 6 bad ones are awkward.

b.) OMEGA = reverse rebid or jump-shift in minor after positive response --> asks for fit in opener's suit and controls (A = 2, K = 1):

This is also not WJ2005. The auction 1♣ 1♠ 2♥ is the only "real" reverse as 2♦ is Bubrotka ('05) or Odwrotka (older). And this shows of course 18+ with 5+♥.

1♣ - 1NT -
2♦/♥/♠

These are all natural in WJ2005, but usually 2♦ is played as a relay asking 1NT responder's distribution. Let me know if you want to know the responses to the relay. Simplified: with 3-2 in the majors you bid your 3-card major, with 3 - 3 you bid 2NT and with 2254 you bid your 5-card suit

1♣ - 1♥/♠ -
2NT
the balanced 18-20 hand?

Usually yes, but might still be even stronger. He could have 30 balanced

e.) What is
1♣ - 1♥/♠ -
3NT ?

A solid suit minor with side stoppers. Unlike in "standard" the solid suit may also be ♦ of course.
