1. standard
2. easy check behind river
3. standard
4. check behind turn and reevaluate on river or bet/fold turn
5. fold flop

Hand1: Fold river, as played, obv check river
Hand2: wp
Hand3: you need about 33% eq, so wp
Hand4: Villain seems paasive, so would fold on the flop. as played just call turn, there is no value in raising.

#1 I would have raised to 4bb pre, potted flop, shipped turn.
#2 Stealing with these hand types is tricky from cutoff versus looser villains.
Look for nitty button villains to steal from cutoff, that way you steal the button position from them.
I'd also bet a bit smaller on turn, by hero betting 3/4 pot, villain nearly never has a weak holding there if he calls; which makes check behind on this particular river an easy choice for me.
#3
#4 Check behind turn or bet 1/2 pot and fold to shove. As played, fold turn. River is check behind usually to for me.
#5 Similar problem to the JT hand, you're likely to get called or worse here, 3bet so I fold preflop. Play tight from early positions like maybe 11 or 12% until you get more experience and can read villains well.

My opinion only by the way, don't take this for any sort of expertise on my part.

Hand 1: fine.
Hand 2: there's no benefit to betting on the river here. Villain is mostly folding worse hands and calling or raising with better hands.
Hand 3: why is the pre-flop raise so large? Otherwise, it seems fine. Make a note on Villain.
Hand 4: check turn, call river.
Hand 5: fold pre-flop. Fold again on the flop.

1. In this hand you have to try to get it in.
2. xbehind river. If you decide to bet/fold -bet smaller on river.
3. The raisepre-flop is normalwith 3 limpers in front.
4. xbehind turn. As played- fold after the raise.
5. Very loose open raise with that hand fromEP. On the flop, when facing "the famous" min-raise I thinkwe have to fold.
