Trap at the finishing line 2

Here two new cases at the finishing line:

Case 4: As Yellow at position 2 (no overlap) I try to slow down as much as I can. If B passes to windward I have the opportunity tu luff.

Is it an option for Blue to overlap leeward, what are the risks? In this case, who wins the match?

Case 6: This one is much at one time, and probably cauzsing some penalties: My Questions:

a) Y clear ahead at the Zone, does Y have the right to ask for room to tack at the boat (position 3)?

b) Did Y his/a penalty (position 5)?

c) Does B have the right to go inside at position 5 (I assume yes according to the previous answers)?

Starbord boat tacking

Here a situation that happens very often. Yellow boat wants to keep the right side but blue is able to cross behind, one possibility for yellow is to tack in front of blue, but...Blue Y flag at position 5. What ist the umpires decision if:

A) At position 4 the boats are on a collision course
B) There is no collision course at position 4 (blue crosses behind) but blue luffs to a collision course while yellow is tacking

Trap at the finishing line

Since 2 years I have seen this situations seveeral times, they evolve very quickly and most of the time the umpire decission are different.
As sailor I can gain or lose the match within seconds wich is fine but I do belive that small details have a big impact. What do you think about?

Case 1: Yellow with outstanding penalty before finishing line. Yellow has to avoid collision right after both boats have crossed the finishing line. Yellow Y flaged at position 4.

What is the umpire's desicion and who wins the race?

Case 2: Yellow with outstanding penalty before finishing line. Yellow has to avoid collision before both boats have crossed the finishing line. Yellow Y flaged at position 4. Yellow crosses the line first.

What is the umpire's desicion and who wins the race?

Case 3: Yellow with outstanding penalty before finishing line. Yellow has to avoid collision before both boats have crossed the finishing line. Yellow Y flaged at position 4. Blue crosses the line first.

What is the umpire's desicion and who wins the race?
