The reason for raising pre was a bluff.
Which translates to a steal.
It's not stealing when you do it from MP - too many players left to act.
If you want to play a bit looser because the table is nitty, then you look to play hands that are outside your opening range for the position you're in, but not by so much that they can't really stand a call. K5o is a trash hand that'll hardly ever flop well. At most you should add that to your BTN range if the blinds are really nitty. In all other cases you should toss it.
Suppose your "standard" opening range from the Hijack is something like 22+/A8s+/KTs+/QTs+/T9s+/ATo+/KTo+/QTo+/JTo (a 19% range), then you're looking to add stuff like A7s-A2s, K9s, Q9s, J9s, 98s-76s, A9o-A8o, T9o (which is a 24+% range). The difference isn't so big that they'll pick up on it, or that it'll hurt your overall equity if you do get called.
Also, the reason you're stealing blinds only from late position is that you'll have position on your opponent postflop in the event that you get called. If CO and BTN call, then you're in trouble postflop with K5o.
they kept letting me steal the blinds, so I kept doing it. it wasnt a c-bet for the sake of continuing aggression. it was again a bluff. i was banking on the probability that they didnt get a piece of the flop either. and maybe they had a straight draw, they would have had the wrong odds to call and see the turn if i actually had something. Im out when they play back.
It's rarely going to be wrong to call a half-pot bet on the flop with a good draw. If they hit immediately, there'll be two streets of implied odds, and if they don't hit, then there's always the chance that you were just c-betting and that they'll get a free river card, which doubles their flop equity.
No OESD or flush draw is EVER folding to a half-pot bet on the flop.
according to 'easy game', aggression = fold equity + pot equity. pot equity was virtually zero, but fold equity was high.
The more people there are in the pot, the lower your fold equity is. That means that the more people are in the pot, the more you should focus on value-betting instead of bluffing.
With just one overcard, no draw whatsoever (not even a backdoor draw), two cards between 8 and J on the board, a two-tone flop that you miss completely, and 3 opponents, the only possibility for you is check/fold. That board is so wet, and it hits a coldcalling range so hard, that you'll be ahead here almost never, and that anyone that did get a piece of that board isn't going to fold to a smallish flop bet.
You got extremely lucky that they all missed the flop.
I'm thinking this'll work less than 10% of the time.
I do not believe that this is ever going to be a winning move. Just because you won it this time, doesn't make it +EV decision, imo.
