400 NL, I isolate a donk and hit the flop hard. Extraction?

[SABR42]

Villain is a passive fish preflop (55/6), but makes big bluffs after the flop.

I dunno, I don't like isolating this kind of player with this sort of hand. Although you are a better player than I am [img]/images/graemlins/wink.gif[/img]. Post-flop is sweet I reckon.

[too eazy]

i play this the same everywhere but pf.

[too eazy]

actually i probably bet 100 on the river, maybe 90.

[CalledDownLight]

I like going with $188 on the river. Don't like preflop.
