[McMelchior]

As already stated by others, "loose donkeys" are per definition the least profitable type of players to try to bluff off a pot (whereas they're great to have with you when you're value betting).

"A bluff must tell a convincing story to succeed". You story suffers already from the get-go in credibility because of your PF over-raise. No way to see if the antes have set in yet, but even if they have you're raising pot + t75. Generally that's a signal of weakness.

After the flop is it very hard to see why you are pushing - there are no plausible draws - except for the possible open ended str8 draw, but A or 9 will come max 18% of the time, and you would be happy to see villian commit chips here with QJ instead of folding.

Villian is going to have a hard time imagining what the threat against him could be. PF over-raises does not signal prime pairs.

Your best hope here is probably an automatic reflex fold. So you're basically resorting solely to brute force in a situation where there should be a decent amount of play left in your stack.

Best,
