Mind Crush & Ritual Spells

Let say...

I set a mind crush
next turn opp play ritual spells...

1. Its legal to chain this, correct ?

by lucky chances I guess the monster written on spell ()

2. What happen afterwards... resolves without effect correct ?

I also thinking, opp would chaining quick-spell ritual like contract with dark abyess to my mind crush

3. What happen if this rare case happens (Althought I am sure very slim chance it would happen)

1. Yes
2. Yes
3. There is no ritual quick spell, you can not chain any ritual to mind crush...

1. It's legal to chain.
2. The Ritual Spell will resolves without effect.
3. There is no such thing as Quick-Play Ritual Spell exist, so there's absolutely no case here.

If you have another of the ritual that fulfills the ritual spell, you will have to summon that ritual monster

I thought we choose the Ritual Monster at activation before it can be chained? :-?

Hand/Deck cannot be targeted.

OK then, I forgot that.

But mind crush send all card (ritual monster) with same name ?

He means, Contract with the abyss can summon any dark. So if you have relinquished and demise in your hand for example and your opponent mind crushes relinquished in chain you have to summon demise (if there are 8 stars to tribute)
