Some question on some card effect and ruling

Gorz effect:

example

Monster A 1500 attack

Monster B 1500 attack

i took 3000 damage total so i jump gorz the power of the token is 3000?

Bottomless trap hole vs TG wonder magician

Player A summon TG wonder magician

Player B pass

Player A activate TG wonder magician effect target face down card (bottomless trap hole)

Player B chain bottomless trap hole?

so can player B chain?

Gorz: Read the damn card

Wonder Magician: When this card is summoned successfully, first you ask if you want to activate the effect before actually doing anything else.

In scenario 1, the attack and defense points of the token will be the same as the last amount of damage you took before you used the effect of Gorz.

For scenario 2, Player A will have to declare on using Wonder Magician's effect selecting a target, then Player B would be able to chain something, in this case, bottomless trap hole.

Thanks all
