Crypto headhunter - flopped the nuts

[registrar]

Second hand of $20 headhunter. For those of you who don't know the site, standard is very loose and excrutiatingly bad. For those, who don't know the tournies, prize pool is 50% standard payouts, 50% put on the 'head' of each player so every time you knock someone out you win a little money (and the value of your head goes up).

I recognise villain's name but no reads. If he's played me in one of these, he'll think I'm an iso-shoving maniac.

Default read is that villain's range is more or less anything pf and it hasn't narrowed at all by the turn.
