New to poker (this is my third week playing), but here’s my thoughts on the streets.
Preflop: Iso-raising is a must with a hand like Kings. Poker sites would recommend 4BB in your position, but from my experience on this site, your 6.5BB is a good size - if there’s customers, keep increasing the size. In fact, given that mediocre hands called you, if anything, you didn’t size big enough - I’ve went up to 10 BB before on loose tables on this site.
Flop: The flop is problematic, because it completely misses your preflop raising range. When you bet, you have three goals in mind:
- Stop worse hands from improving.
- Get worse hands to put more money in the pot.
- Get better hands to fold.
With this in mind, I think betting with Kings on a board is good, because it gets 8x to call you. The sizing you chose is a bit big for my tastes, but it probably needs to be big enough to fold out hands like 67, even though the implied odds.
Turn: Here, I think you should figure out what you’re representing, and what your opponents are representing. With your iso-raise and flop c-bet, your range looks something like 88+, broadways, maybe A4s or A8s, 89s, 8Ts, 9Ts, 9Js. So by c-betting the turn, you’re advertising a lot of hands with jacks.
The second thing is to look at your opponents hands, and ask what they might have and what you’re trying to do. Hands that call your flop c-bet are pairs, 4x, good 8x holdings, and gutshots. So by betting here, you are folding out gutshots (good), folding out 8x (not very useful), or betting into 4x (not good). You’re not extracting value from getting jacks to call, because the only jacks that made it past the flop are already better than you.
When your opponent shoves, I think it’s a clear fold. Shoves here represent 4x, which you have low equity against, and you can’t even benefit from implied odds when you river a King when people are already all-in. Other possible shoves might be 88, 8J, JJ, or hearts, but I think the EV from calling hearts or 8J (or the extremely unlikely 9T, QQ, or pure bluffs) doesn’t make up from the lost EV from the other cases when you’re behind. I also note that from my personal experience on this site, people tend to not check-raise with a bluff.
