Partner opens 1H. Probably at least 9 times out of 10 the correct contract is 4H. So I see the question as how to find the other possibilities without creatng som much confusion tht you land in sme silly contract.
1H-2C-2S. Already we need agreements. If opener is minimum I prefer a 2H rebid on 5. The 2S does not have to promise the moon, but it should be something extra. We can rule out 6C and 6D as possible contracts and 3NT would seem odd, so I bid 3H. If we belong in 6H we have a decent chance of finding it.
1H-2C-2D. Now 6D is in play. I still start with 2H, I plan to show diamonds later. This is a little risky as partner might think this shows a stiff spade but I think he shoould allow for 2=3=4=4.
1H-2C-2NT-3H. Since partner (my partner) is allowed to rebid 2H oveer 2C on five, I assume he has a spades stop for his 2NT. Still we probably belong in hearts. If partner, over 3H, chooses 3S I would regard this as something of a last train offer to play in 3NT. I might take him up on it but I think I still go with hearts, so I bid 4C in case that interests him.
1H-2C-2H-3H. I'm showing a decent hand and I more or less have one. On the auction so far I am not embarrassed to lay down the dummy.
1H-2C-3C-3H. Partner has hearts and clubs, I have clubs and hearts, the ball is n his court.
I don't see this as a problem hand.
I might hunt up Fred's articles on an improved 2/1 just for the fun of it. No doubt there is room for improvement on standard. But I think when problems arise in 2/1 we again have a 9 out of 10 probability that the difficulty is not that the system is bad but that the players have not discussed what means what. As mentioned, I like 1H-1m-2S to promise a little extra, using 1H-2m-2H with a minimum. It's different when it begins 1D-2C. Now there are two majors to sort out and I think we need to get started, even with a minimum. So 1D-2C-2M simply shows four cards in M without necessarily any extra values. These are my preferences. Are they the same as the preferences of the guy sitting across from me? Often I have no idea..
A little history might help. This all came up back in the day when I was playing with Bob Holmes as my partner, and although we were reasonably decent players we could not compete against the true experts so we decided if we couldn't outplay them our best chance was to outbid them. This led to 3 system inventions (all 3 published in Bridge World) that we didn't get to play for long but which still make sense to me.
First, to beat the pros we figured we needed to be able to find more skinny slams. This led to the idea of 2/1 in a minor as a source of tricks - a decent suit. That left the hole of the 2344 hand. That led to Better Berger.
Second, we decided that the most logical game contract after we open a weak 2-bid is game in the major opened, not 3NT, so I devised a losing trick count system for weak 2s. That was pretty sweet.
Third, we adopted a singleton-showing method over inverted minors, with 2N being shape showing only.
Then we didn't get to play much for a couple of years and that was that. So other than the weak 2 structure, I don't have a lot of actual play time with the other bids.
So that's the history FWIW.
