Yes this is early but I don't think its right to only bluff strictly on reads ("find out what exactly he's donking with 1st" - well the problem is I won't know exactly what he's donking with for awhile if ever (cuz it can change), plus he already donked before this so I'm assuming he can do it with a wide range).

My thought process:
There are a lot of missed draws that I can get to fold.
He didn't 3bet preflop so QQ and high Q's should be ruled out.
88 only has 1 combo.
A8 type hands seem silly to play this way, especially because he cannot have 8dXd.
My hand looks like an 8, 99-JJ, Q, Overpair and I would think a random Q would be checking here or atleast betting smaller as its hard to get value out of worse.
My hand could easily be a missed draw so there is more value for villain to check and induce a bluff.

So the only hands that kinda make sense that is vbetting this river and calling a shove are 86s, Q8, and 66.

Is this spew and should I just stick to learning more about villain before making a play like this?

I don't like to make elaborate bluffs in the first 20-30 hands..seeing as people are more call prone.

It looks like you have a queen that wont give up, and his turn lead looks like two pair that doesn't want you to fold

I also dont expect people to fold TP or even 2nd pair vs me early

if you were playing some1 competent i'd like this you rep trips well. not really against ppl who cant hand read and especially early at 50nl i dont think ppl rly fold...

i like it
