-I'm posting this hand because its a spot where I feel like I almost always shove AK/AQ but I'm not sure if this is bad
-villain in this hand is loose pre, 33/25ish type who rarely folds to 3bets

Hand 3
-Same villain as above, I ended up losing the above hand
-This is one of those dumb hands where I was getting raised on every table at once, and lost track of who was aggressor in hand so donking turn was by accident. Actually I didn't even realize I donked turn, I thought originally I had c/c flop and turn and donked river only lol (less tables imo).
-anyhow.. easy fold?

1. I'd fold and not think about it too much.

2. I'd want AK with a spade to shove here unless villain is really weak.

3. Turn is too fancy for me. As played I'm calling river.

Fold all three.....in hand 3 is he really planning an elaborate bluff on a dry A high board?
