How is my bluff line?

Villian is 42/3

The logic made sense to me in my head whilst I was playing the hand, I open from CO as standard and villian calls then leads flop on an A77 board. Now I know for a fact that he's insta CR an A and a 7. Like a million per cent.

So I float the flop to take it away from the turn, so he bets $2 again on the turn and I shove over him for the $10 he has behind.

Is this standard? Or should I just be staying away from the hand cos he's a fish and obv never folding even high cards.

I dont really like this much, id prob save this for when you have FDs. You need him to fold 58% of the time at the moment [assuming you have close to 0% equity], you'd need him to fold 33% if you had a 25% equity draw. I think this would be much better when you have XhXh. Saying all that, if you're sure he cant have too many nut hands at all, then this would prob be fine.

Id fold pre too as standard [dependent on button with stats/reads]
