Can someone link me or tell me the chain speeds? of the Yu-Gi-Oh cards?

Question

As in effect of monsters, trap cards, quick play?

Could I activate a monster's effect during my opponents turn?

or while them in their battle phase?

Answer 1

as soon as you activate

Answer 2

it all depepnds on the card. trap cards can be activated almost any time your oppeonent does something in his turn but cant be activated when set. they can also be activated on your turn. spells can sometimes be activated on your opponents turn but it depends on the card, most quick spell cards, which have a little lighting bolt on their name, can be activated almost any  time. monsters with flip effects can be activated when your opponent attacks them of if you flip summon them on your turn.

Answer 3

You can activate quick play spell or trap card when your oponent is attacking you, that is if you already played down the card on the field

Answer 4

Alright, here's the official list from the rulebook:

Chain Speed 1: Normal Spell, Continuous Spell, Equip Spell, Field Spell, and all types of monster effects except Multi-Trigger ones.

(This speed is the slowest)

Chain Speed 2: Quick-Play Spell, Multi-Trigger Monster Effect, and all traps except counter traps.

(This speed beats Speed 1 and other Speed 2 cards)

Chain Speed 3: Counter Traps.

(Fastest speed, only beaten by another counter trap)
