IMO, my villains in the general public tend to hold AK/AQ in this spot vs KQ, TT, AA, but Dr can rep all the above. If stacks were 10x higher, I'd raise to $125 for another evaluation (fold on jam'ish raise) but given the small stacks I'm jamming with way more confidence than doubt. Certainly Dr would bet the same with AJ/AT, but his bet feels like its trying to induce a fold. If Dr held either KQ or a set, a more encouraging bet in the $25 range would have occurred unless the overbet is trying to sell weakness, I dunno the dynamics with you two but most of this thread is tldr for me to figure that out.
David O's hand is so well concealed that the Dr can bet with reckless abandon with any AQ/AK/AT. TT or QJcc less likely but all possible. If Dr has the nuts'ish hand, I wouldn't play Davids hand differently (jam) unless playing very deep.
Edit: If David folded he must never play cards ever again.
