It's a weird turn, because the ace is better for our range than his. We hit this card more often. So it's a good card for us to rep. But when we bet, we can't reasonably expect better hands to fold, nor can we reasonably expect worse hands to call. So we can't value bet, nor can we bluff. Our best hope is for the turn to check through, then we can maybe check/call blank rivers to pick off any missed draws and king high floats he decides to bluff.
