Is this a glitch or not? (Showdown)?

Question

I was playing Pokemon Showdown and my 252 HP / 0 SpD Azumarill survived an Alakazam's Psychic with 2% HP left and the Alakazam had+4 special attack.
Is this a glitch or not?

EDIT:light screen was up but still should be an OHKO shouldn't it and azumarill had 31 ivs in everything and so did alakazam

Comments

what were the IVs on Alakazam

---

+4 special attack? So like it used clam mind 4 times?

---

@kawai it had 31 ivs
@Arcazeus yes 4 times

---

im gonna need EVs too.

---

Azumarill has 252 hp 252 attack adamant nature and the alakazam had 252 special attack 252 speed timid nature
I know all this because I was battling my best friend so he told me

So read my answer, it was definetly a glitch.

Answer 1

Definetly a glitch.

+4 0 SpA Alakazam Psychic vs. 252 HP / 0 SpD Azumarill: 453-534 (112.1 - 132.1%) -- guaranteed OHKO

Even when Alakazam has 0 SpA EVs, it OHKOs.

---

ofc it's possible for a +4 to not OHKO an Azumarill, but only if it's something like this:

+4 0 SpA Alakazam Psychic vs. 252 HP / 252 SpD Assault Vest Azumarill: 205-243 (50.7 - 60.1%) -- guaranteed 2HKO

A. That Alakazam has 0IVs and 0EVs on SpA and an Adamant Nature (-SpA +Att), which I doubt Is what your opponent had.

B. Azumarill has 252 SpD EVs and a Calm nature and was holding an Assault Vest, you said your Azu had 0 SpD EVs (which also means you probably didnt have the AV and the Calm nature.)

This sort of thing is the only bad thing about showdown.

(What do those numbers in the brackets mean at the end?)

---

the amounts of HP it can do (it varies)

---

Actually it's theoretically possible
Try a + SpD Nature on Azu (Which Seth nether specified) and no IVs on Alakazam.

Or go with AV Azu.

Or maybe Light Screen was up?
