AA facing big river raise

[ErinJeff]

Villain in the hand is running 21/7/2 over 44 and hasn't previously come to my attention. Two things make me question this river action, he instacalled the flop and turn and instaraised the river and his chat says "busted flush", but this feels like a set. I'm not sure why he chatted me. There was a pretty long delay before he said "busted flush." What do you do on the river? Should I have done anything different on any other streets?

Preflop I've been experimenting with 3BB raises in unopened pots and then using 4+1/limper for multiway pots. I haven't noticed a difference in pf calls/folds and it helps keep the pot size down a bit when I'm stealing unopened as I can cbet 5BB instead of 6-7 on the flop.

I was wondering about this. Thanks for answering my [unstated] question.

if they're talking about a hand supposedly they'll never mention a hand they beat, take that for what it's worth
