in 3, i dont want to tip that i have at least a 2 on the turn because i want whoever has it to bet the river so i can push or for the flush draw to bluff and cause the 2 to raise so i can push easier or so that everyone will check to me so i can bet/push looking like i missed my flush.
The point of raising the turn is that everyone will probably check to me on river meaning ill bet pot and get called, possibly raised by a boat (but you know how passive fish can be with the nuts) so if i just call i encourage those showing aggression to continue to do so and for those who think they can bluff it to 'have a go' at a bluff, so to speak.

Hand 5 is just bad.
I should have c-bet and shut down on turn where im beating nothing, my problem was playing a big pot oop. I played his horribly, if id c-bet and folded thereafter it would have been fine.

Hand 4.
If id have been sure he didnt have KQ id have shoved, but on the flop im a dog/ 55/45 versus his suspected overs. On the turn when its blank i can bet/push because hes a dog at that point.
Normally this flop is a fold i think compared to opps stacksize and raise range preflop.
