This hand shouldn't be in your overbetting turn range at meaningful %. Ace of hearts blocks folding range, 8c is whatever blocker. You have many better bluffing candidates and value range is likely KQ+.

Something like 100%-125-150% preferred overbet size by many players. Using 200% would be not effective as people overfold already and some(tend to have too many strong hands as flop call).

My turn strategy would be to split my range with a 50-65% bet size and an overbet of 150% or so.

Fwiw this combo would not slide into the overbet range. I would prefer bluffs that have higher equity and nut potential, or block villains best bluff catchers
