you have the 5th nuts and its 25nl. imo its fine to play a big pot there without a passive read. i just think you should've led or raised flop and bet more on turn, etc. basically get all in with less bets.

Board: 9h 9d 5h

equity (%) win (%) tie (%)
Hand 1: 79.1491 % 71.39% 07.76% { Ac9c }
Hand 2: 20.8509 % 13.09% 07.76% { 66, 22, 92s+, A9o, K9o, Q9o, J9o, T9o }

Remember poker is never ending, and not about results of one hand.
