OK... given this is a marginal call PF (SB and BB both had 50-60+ VPIP and I figured one or both were likely to call), what is the correct line with bottom set here?
As played:
Flop - I'm capping for value and protection from flush/straight draws.
Turn/River - Raise is for value and protection, resorting to call down on 3-bet given possible better set v relatively tight villian.
Questions:
1. Is flop CAP ok? Given any FD/OESD is raising here for value with 35% / 31% equity respectively, we are ok to CAP with our equity (which is? - not sure how to account for FD hand in equilator...)?
I'm pretty sure I'm confusing something here... we have a made hand, are probably ahead and with 7 outs to improve to quads/full house on turn. Simple answer is bet because we're likely ahead and drawing hands are only one subsection of villians possible raising hands?
2. Is raise on turn correct given action on the flop? Should we be capping here or are we already in call down mode facing turn bet with bottom set and given action on the flop? I suspect raise/call down is correct because there are still worse PP / Ax / 2 pair / draws raising this turn, although a CAP must be close?
3. What is the correct line on river if we hit a full house, where the villian bets the river? Raise/Call? or just call given the level of aggression and strong possibilty of facing up to a better full house?
gives you the fullhouse.
