Treasure Mine - Systems & Style - Chapter 3 - 2H with less than 8 - Part II

(The recent world championship gives us a treasure trove that can be examined to study systems and style implications for success. For this final chapter of the study we will look at when 2H was opened with less than 8.)

The next board with a 2H opening with less than 8 was the last board of round 16:

In Brazil-South Africa, North passed, and EW had a free run to 6D, down 2:

In the Closed room, South overcalled 2S (opposite a passed hand but still dangerous), and EW parked into 3NT, just making for 13 IMPs:

The England-German match saw the German North start with 2C (5-5 hearts and another, 5-11):

EW found 3NT, making 660. In the Closed Room, 2H was 5+Hs & 4+ minor, 5-9:

South raised to 3H, which could be wrong by the Law-of-Total-Tricks - they often will only have an 8 card trump fit - this cost 800 and 4 IMPs.

The final match of the round robin saw one last 2H opening with less than 8:

In the Closed Room, East asked over the Multi 2D, found West had a minimum weak 2 in hearts, and bid 4H, making 5 for a push:

In the Open Room of Indonesia-USA, Meckwell sat for 4H, and that was making five:

In the Closed room, South doubled, and NS were only -100 in 5C, for 8 IMPs:

In Israel-Sweden, 2D was Multi, 2S pass or correct, and West jumped to 4H with good playing value for hearts (2S implied willingness to play at least 3H opposite a weak two in hearts). Now South doubled, North bid 5C, doubled by East for -200:

In the Closed Room, NS got to play 5C undoubled, so gained 3 IMPs.
