hand 1 im not sure if its right but calling the flop with 6 turn cards u can continue profitably after (2 5s 4 3s) is enough for me getting 9:1

Against an unknown its close for me w/ only 6 likely outs only getting 6:1 (that A actually improves some of his worse hands on the flop he might check-raise). But there is a good chance u could have the best hand but without knowing his tendencies its tough to say if he ll check the river with those, so i think my default vs an unknown is fold. Against many I'd call on the turn here however.

If u have the read on BB as either a folder, weak-tight or very reasonable, raising the turn mite not be horrible. u got 6 outs and could take the free showdown and possibly fold out a better hand. The only problem with the "bluff" raise is if we raise and he 3bets, now we have to see the river having bloated the pot so much with likely 6 clean outs getting like 10:1.

hand 2 i give up without any thought of other possibilities.
