Hand Evaluation - 2/1 Doubles
When partner makes a 2/1 , D.S.I.P. theory is replaced by forcing pass theory. However ,my partners & I have the understanding that 2♥ after partners1♠ opener is not forcing to game if the suit is rebid. After a major opener , a rebid of a minor is not game forcing. We have these understandings to make our forcing 1NT structure more manageable by taking these hand types out of the equation. In addition , we play 2/1 in competition as not a game force if the suit is rebid. To cover these hand types , D.S.I.P. theory comes into play. In the heat of battle , since these hands are an exception to the rule , we still assume forcing pass theory. However , if it presents itself that we can indicate the different hand type , we seize the opportunity.
Partner opens 1♠ , you bid 2♣ with ♠Jx ♥Ax ♦xx ♣AK109xxx , they overcall 2♦ which gets raised to 3♦ so around to you. A direct double simply means my 2/1 was of the game forcing variety so D.S.I.P. . A pass would say I just have a club suit type 2/1. Same with hearts bid over spades in a competitive auction. A direct double after a minor 2/1 bid is like a THRUMP double. Bid 3NT with a stopper in their suit. With a stiff in my suit & the appropriate hand , feel free to convert for penalty.
What about 2/1 in competition ? Same basic idea . A direct double just tells partner your 2/1 is now forcing to game. If you just had a suit 2/1, you would simply rebid your suit non forcing. You have the choice of a Q bid also but that should imply a fit with partner. ♠Ax ♥AKQxxx ♦xxx ♣xx Partner opens 1♠ , they overcall 2♣ you bid 2♥ & they bid 3♣ so around to you. A double here just means that your 2/1 was serious , so we are going to game somewhere or they play it doubled. A double works like a Q bid but you are conserving room & giving partner an option. A 3♥ bid would not be forcing.
♠xx ♥AKQxxx ♦xx ♣xxx Partner opens 1♠ , you bid 2♥ & they bid 3♦. This gets passed around to you. Your 3♥ bid is not forcing, but you “owe” partner another bid. You must double with a game forcing 2/1 . A direct double is a more flexible bid to show your game forcing values. A Q bid sometimes rescues the opponents from a bad spot. A Q bid should imply a fit with partner in most cases. All bids in 2/1 auctions other than rebidding your suit are of course forcing to game with our understandings.
1♦-P-2♣-P is always forcing to game. There are no D.S.I.P. understandings in these auctions. Doubles & passes are in accordance with forcing pass theory.
