I think I've messed up my head with reading too many posts in a short space of time! I'm second guessing myself too much.
I folded in the hand, figuring that not closing the action there was too much chance of this coming back to me for 2 more bets, and am now wondering if getting 7:1+ good implied odds I should have found a call here???

FWIW I'm estimating 4.5 outs here (2 tens, 3 aces discounted to 1.5, and BD straight)
