6.50 Fold AA here?

Bet closer to full pot on the flop. If you've been very active the last few hands you don't need to worry about him folding too easily. He's just as likely to think you're bluffing with a big bet, and even if he doesn't have a flush draw, a heart could kill your action so get the money in.

Push the turn - a flush is only part of his range and you have the NFD which makes up for some of those times anyway.

If you check the turn I like a call on the river. If he had a T on the flop he's likely to have raised, and the check on the turn means "I'm not sure where my 88 is right now" more often than it means "I'm slowplaying my flush".
