Hi,

I've started learning 2/1 Game Force system and have some simple questions about how does this system work.

Let's consider following bidding:

1♣ - 1♦
?

What i should rebid with hand ♠KJxx ♥KQxx ♦AJ ♣KQx?
- 1♥
- 2NT

I suppose 2NT is correct answer, but what shapes are acceptable for 2NT rebid? What about 4-4-1-4 or 4-4-0-5? Is still 2NT correct or 1♥?

My second problem is:
1♣ - 1♦
1♥ - 1♠

I suppose 1♠ means fourth suit, but let's asume both bidders have four spades. How to agree spades after that beginning?

Can you recommend me some books, where i can find those basics? I already have "Two over one Game Force" by Max Hardy and the same title by A. Grant, E. Rodwell.

Thank you for help
David

You're correct that 2N with 18-19 balanced is the rebid after 1♣-1X even with a 4 card major. When unbalanced, say 4414 or 4405 (or (43)15, etc), bid your major naturally showing an unbalanced hand (in the Walsh style, where NT bids can have a 4cM). So with these either 1M or 2M depending on whether you feel you're strong enough to force to game. I'm less sure what's "standard" with 4-4 in both majors, but with an unbalanced hand you're rebidding one of them .

I think many people play 1♠ as natural after 1♣-1♦-1♥-1♠ (and 2♠ is 4th suit GF). After 2♠ 4th suit GF, 3♠ would show a good hand with 4 spades I expect (4414 or 4405). I'm not sure this question qualifies as "basics" but hopefully this helps.

Thank you for explanations.
