Generally when a pot is killed tight games get tighter, and loose games get looser, I really do not know what people are thinking in kill pots. Does position become more important? Should you play more hands, less hands?
My answers are predicate on a Limit game. I've never seen a kill on anything but a Limit game.
- Does position become more important?
The forced action gets expensive quickly, so being behind the kill is a huge advantage, but otherwise, the "rules" of position are pretty much the same as normal. E.g. play weak holdings less often in early position.
When you have the kill, and you are better than your opponents, defend it with your life. If you have the kill, and are worse than your opponents, let it go. The game simply plays bigger.
- Should you play more hands, less hands?
I tend to play more kill hands because the bets feel bigger, and opponents are scared of the bet sizing. You can induce a lot of poor play just being aggressive, when simple aggression doesn't typically work in a Limit game. Many players "won't pay more than $X" on a draw in Limit, regardless of the correctness of that call.
I do not profess to be an expert with kill pots or straddles. But, my understanding is that it should not change your starting hands, but it should change your opening raise size. There's enough money committed to the pot that you should take into account your X sizing as well as ALL of the pot.
It's generally a mistake to raise 3X of the kill if there's other limpers in there. You should remember to calculate the pot as a function of all limpers and then 3X raise the pot (or whatever other X you think makes sense).
