Q9s

Its quite hard to say anything about a hand when you dont know anyhting about the opponents playing style. At least some stats would be good to have. Against unkown fish (I suppose a good player doesnt cold call in this situation)I'd call cause I dont close the action and its easier for the player behind me to put in one more bet with a worse hand. You may occasionally run into some weird slowplay as well, and BB could be on bluff too, or a weak pair (which he folds), so you can end up just valuecuting yourself.

if i dont post stats or notes its because its basically an unknown i had like 5 - 10 hands on both of them .. both were of course something like 60/0/0

I don't get the river raise at all. They both continue vs your cbet on T55 rainbow. This already means one of them is very likely to hold Tx or 5x. When he bets the river I'm between calling and folding, calling is better for me as they could still both peel the flop with stuff like J9, QJ or lower pairs or Ax. Also you could get overcall by weak Ax or 44 from the 3rd guy if you just call, if you raise, you often isoraise yourself stupidly vs a better hand.

I agree with taavi, your raise on the river doesn't accomplish anything, a better hand's not going to fold to your raise and you just risk isolating yourself vs a better hand, this is a pretty classic spot to go for an overcall
