The only right thing is to tack to starboard at the start boat - or being banned and maybe black listed at lazy.se..

Boat (A) -Ww is not entitled to place between (B) -Ww or (C) -Lw and the start mark (start boat).
In the situation makes (A) a tack to the right, as she should.

Boat (C) -Lw authorized to luff both (A) -Ww and (B) -Ww, up to wind-eye (before the start) to keep them on the wrong side of the start mark (start boat).
After the start can (C) -Lw not sail higher than close-hauled, (if rule 17 applies between them) but she can still keep (A) -Ww and (B) -Ww the wrong side of the start mark (start boat).
Both before and after the start so can (C) -Lw change its course but must give room so (A) -Ww and/or (B) -Ww can keep clear according Ksr 11 and 31, ie, (A) -Ww and (B ) -Ww must be given space to clear Rrs 31 when (C) -Lw makes its change of course, and meanwhile passing the starting mark if (A) -Ww or (B) -Ww only can pass on the inside. (A) -Ww and (B) -Ww must always sail on the wrong side of the mark, as long as it is possible.

In the situation as perceived (A) -Ww the location correctly and make a tack and right turn, as she should. (B) -Ww is trying to intrude between the start mark (start boat) and (C) -Lw in violation to Rrs 11 and 31.

Since (C) -Lw not sail above close-hauled (proper course) or leave space there is not sufficient space to (B) -Ww. (B)  intent is to try to get in between (C) and the start mark (start boat) and when she realizes that it is impossible, she choose to hit the mark instead. Had (B) tried to get in between (C)  and the start mark (start boat), she had been banned for an apparent deliberate violations Rrs 11 and 16.1 and for that actual intention and purpose, to violating against Rrs 2

NOTE: A starting mark can never be regarded as an obstruction, even if it concerns a start boat!

(B) lose a lot more to hit the start boat rather than tack to right and now becomes passed of (A)  at the leeward side. Before (B) get up to speed (A)  will do several boat lengths in front of here. In addition, (B) must do a 360 because she received a PEN 31, so she'll be far, far behind.

If (B) -Ww had chosen to go in between (C) -Lw and the start mark (start boat), she had ruined the start for (C). Therefore, I have introduced to get banned and tacked on the black list of attempting such a maneuver repeatedly.

P.S. Then the blacklist came to this kind of bad behavior more or less is ceased.

LAZY.SE:s COMMENTS ON SITUATION
To penetrate into the starting mark - definition: Room

Leeward always has the right to sail a sustained courses according to Ksr 11 even if it locks Ww to the start mark!
- There is therefore no question of any rights for Ww to get “room" at the starting mark or that the start mark in any circumstances be regarded as an obstruction ...!
In addition, given priority rules between them in numerical order, which means that Ww has to sail and hit the mark rather that she violates Ksr 11. If Ww choose to only violate Ksr 11, she can if she serves on the decision even be folded for this according to Rrs 2

1. A starting mark / mark is never an obstruction, even if there is a start boat involved. (Rrs 19 and 20 do not apply)
2. Rule 15 or 16 can not protect a windward boat from having to touch the mark (start boat) on the change of course from Lw takes place before the situation become locked for Ww.
3. Rule 15 and 16.1 shall apply in the same way as it does on "open water", thus it is question of "room" between Lw and Ww, and there will be no difference at start marks (start boat). However, a change of course can not take place so that Lw forces Ww violate Rule 31 - ie take place so late that Ww does not have the room to pass the mark on any side - ref definition of Room.
4. Before starting signal - Lw with overlapping can luff Ww up to the wind, and forcing Ww on the wrong side of the start mark (or the start boat).
5. After the start signal - Lw can sail "close-hauled" (which at upwind sailing is the same as "proper course" according to Rrs 17) and by maintaining courses forcing Ww to hit the starting mark (start boat), even if both is with course inside the mark . If Rule 17 not apply between them can Lw even luff Ww up to wind, provided it not begin so late that Ww is locked between Lw and the mark (see definition on room).
6. The proper warning is addressed to Ww: If Ww do not have enough room to pass the mark and / or detected too late. Then Ww  have painted himself into the corner. - Do not do that!
7. Comment regarding Rrs 15 and 16:
   Rrs 15 and Rrs 16.1 regulates Lw's obligation to provide an initial space (room) to Ww to keep clear (Rrs 15) and give room for Lw's right to do courses changes and it demands Ww and Lw to give each other enough room to make a course change and room to keep clear Sailing (RRS 16.1).
   
   In the assessment of the change of course "in itself" There is therefore no difference towards a similar assessment on "open water" as a starting marks (or boats) never counts as a "obstruction" that can give Ww a any additional rights to get Room inside a mark.
   
   16.1 prevents Leeward (by the definition of room) from the right to make a course change at the mark so that Ww is forced to touch the mark - Lw is required to ensure that Ww can stay clear to the mark in accordance to rule 31, during here course change!
    
8. Room at the change of course:
   A luff / changing course at the starting mark (start boat) must take place before Ww comes to the point of "no return" and is out of choice to pass the mark on the wrong side. When Leeward changes course, she is obliged to ensure that Ww capable to  keep clear to Rrs 31 – and if they are on a locked side of the mark, until mark has been passed.
9. Rule 14 does not prohibit Lw, with the right of way, to maintain the course and sail Ww, towards the mark or with contact. If contact is made then the Leeward shall be freed by 14. (b). Even Ww can be freed against Rrs 14 for the contact, but it is meanless because she folds for violating Rrs 11 or 31 and in even could be in danger to be folded according to Rrs 2.
