Is Q8 and Q6 in V's range?
Have you seen V play 2-pairs like this?
Would V make big raises with Q
x
(pair + flush draws?)
If the answer to these questions is NO, then this is a
fold. If you really believe V2 is capable of making plays with the above hands then you have to
shove.
EDIT: against V1 (TAG) and this stack, I'd PUKE fold
