Surprising opening replies

In Response To: Surprising opening replies (Timothy Chow)

The opening replies follow underlying laws:

- it is forced to hit a 20 slot - at least for any non point making opening reply. Hittling there is highly profitable.

- it is profitable to bring the backcheckers in the hitting range of blots (builders) in the opponents outerfield

- sixes like to go to the opponents barpoint, especially as long as the opponents 8 point is not strengthenend to 4 men

- it is highly profitable to prepare an attack on the opponents 9 slot.

(See for example that 22 foregoes N oder E for hitting on 9 in case of 64S22H.)

- a 4 men 8 point is strong

- non double point makers possibly make no point, if the point would be especially weak in case of likely opponents further responses.

43S61X foregoes the barpoint in this exceptional case because so much forces sum up for the alternative here:

The barpoint would be rel. unimportant against a golden anchor, the hitting is "forced", the barpoint split goes for an own advanced anchor and simultaneous obeyes the duty go in the range of an opponents builder in the outfield.

52S41T can be interpreted basically in the same approach, i.e. it seems clear that going in the fire of an higly profitable opponents hitting 6 on a 9 slot with 52S41S can not be right. 52S41U spends profitable hitting chances to the oppónents 6/8 stacks.
