A10s, TPTK, board-pairing turn

[bhiatt]

I'm thinking that a 3 bet might have been correct given my reads, with intentions to fold to a cap (?), call a river donk, but nothing more (?), and take a free showdown if either or both opponents called the 3 bet and checked to me on the river. Obviously, it didn't help that I had little information on the unknown, which is the main reason that I folded.

FWIW, the river was a 5, the BB donked and the unknown called. The BB showed 105o for a rivered 2 pair, and the unknown had my hand, A10o.
