Bet folding versus WA/WB

[pureklas]

Has anyone got any general guidelines for when it is best to bet/fold and when it is best to go into WA/WB mode and then either c/c or c/f.

Lately I have been trying the b/f line with difficuly as I hate folding good hands (TPTK, 2 prs, sets, straights). Is the b/f to get maximum value from hands that have good showdown value and may still be ahead? If say the river completes a draw ho much do we bet? I have been aiming for around 2/3s pot.

Two hands for your viewing pleasure. Would you b/f or use wa/wb?

Hand 1: villain is virtually unknown but shaping himself up like a donk 50/1.5 after 30 hands.

Hand 2, ignore pf raise situational dependent...villain was playing tight. on the turn I am sure he is on a draw as he raises the Ace on the flop. The river he bets if i check nearly every time.
