I've got a discussion with a friend of mine about the following hand, he says that my play is too risky/loose play and -EV in this situation. I consider him as (in my point of view) a too tight and straightforward shorthanded player, so this example splits our opinions massively 
I think it's +EV (with variance though) and I would definitely do it again in the same situation. I'll give a humble explanation of my thoughts below.
Titan No-Limit Hold'em, $0.25/$0.50 (Titan HH Converter by Kreatief)

I want to ask you about your opinion under the following two conditions:
a) Villain (ViP: 50%/PfR: 25%)
b) Villain (ViP: unknwon PfR: unknown)
my thoughts:
a)
I actually played vs type a) and I give him a loose handrange for his stealing attempt. He will steal with Ax,Kx,Qx,JT,pp,sc maybe even looser or with any two just out of fun (he is a fish who sometimes likes to make risky moves, especially at BU,CO or blinds)
However, after his all-in I put him on AT+,KQ,KJ,QJ,pp or maybe even any two as a bluff since I still think he is a fish due his loose stats. So, without calculating the proper odds, I would say it's +EV.
b)
I give this villain a tighter range since I don't know him and he could be the tightest rock on earth.
However in my experience, blind battles are often very loose at NL50 and I don't think he would push his whole stack so early with a 3-bet whilst holding a monster preflop hand.
He would rather try to extract more money of me instead of scaring me away, that's why I expect a normal 4-bet with a killer hand like AA or KK which he wants to trap me into a call (-> pot committed) or crying push.
--> His big all-in bet looks rather like a "I don't want to see a flop" bluff bet with AK,AQ,AJ,KQ or QQ-22.
So with this hand range it's maybe not a mathematical +EV, but here as well I expect also a any two once in a while which makes it for me +EV.
So my inner poker sense will surely trigger the +EV(f**k the variance)-all-in button.
Note: I won't call this all-in when we both would be deep stacked (100BB+).
And now the third and most important question:
c) Am I wrong?
