Replying to the taunts was the worst play in this story.

Spotting an apparent aggro fish and targeting him for “chip removal” was a still good plan imo… 🙂

To execute it, you were probably better off having waited for a hand good enough to valuetown him, rarely flatting though,but rather iso-raising to keep others out.

The spot you chose with a one gapper in itself could be beneficial but in this case the pot was 3b already which immediate makes this a rather bad spot to go for with this holding.

BUT, if u still want to go for it (I advise not to unless the UTG raiser is very loose himself and even than ur not deep enough..), I defenitely miss the (min-) isoraise 4b to eg $420 instead of flatting as u might squeeze the original raiser out. (make it a 4b – fold) A reason for flatting might have been your fear that the guy might shove? Playing suited onegappers is easier if you are able to let the hand go if you don't smash the flop or not getting raised.

The final argument against this spot is the fact that you are not deep enough to play the line I outlined above. In itself the line 4b raise-fold to shove is ok at some stages in tourneys but the frequency where you would be able to continue is so low indeed and than you just waisted a big portion of your stack where there are much better opportunities ahead.

So my take in this is that you had a great plan but this was not the way to do it. Valuable insight. Keep playing suited onegappers in unraised pots though, because they are great chipcollectors if you can see the board rather cheaply.

gl in your games!
