Theory question.

[Alex/Mugaaz]

Apologies if this is boring.

You have a made hand on the river in a HU pot vs a very bad player who you assume is on a draw to a flush/straight that is semi-live, or is simply being an idiot calling you down with a very small pair. He will bet or raise if he makes his draw, but he will also bet or raise if he improves to 2p which you beat 80% of the time. Examples below I'm going to slightly change however. Also asssume you get bluff bet/raised 0% of the time. (Ignore internet donkiness where they may bet an obviously worse hand as well)

River:
A) Bet, call raise.
B) Bet, fold to a raise.
C) Check, call.


2) Hard time narrowing his hand down becasue he is just too bad to be readable. However, appears to be a small pair with an open 3 flush and remotely may have a broken gutshot straight draw as well.

River:
A) Bet, call raise.
B) Bet, fold to a raise.
C) Check, call.


3) Villian is bad, but he needs at least a small pair to get started. He won't fold unless someone makes open made hand he can't draw out on. On 6th his board is simply random cards with a 3 flush.

River:
A) Bet, call raise.
B) Bet, fold to a raise.
C) Check, call.

4) Opponent is a decent player, but he isn't that tricky. Appears he has at least a 4flush. If you had to guess he has a small pair and a 4 flush. However if he catches 2 pair on 7th half the time you're beaten.

River:
A) Bet, call raise.
B) Bet, fold to a raise.
C) Check, call.
