OK ... 6 months into this poker thing and trying to get a grasp on pot odds and how to use them when betting. Specifically trying to determine how much is needed to worsen the odds for the opposing player. So I apologize if this is basic stuff but I want to understand the basics.

Scenario #1

10 person 25NL Ring - I'm in MP and put out 6xBB with something like KK or QQ. Let's say I get one caller behind and 4 previous limpers fold so the pot is at $4. Flop comes out ... say 4d 8d Jc. I want to bet enough to push the other guy off his flush draw (again I realize he could have any number of hands but let's use this for my lesson today).

I might put him on AKs so I believe he has 9 outs to the flush and 6 more for top pair. Based on what I have read, that gives him about 15 outs X 4% each or 60% chance of making a better hand.

So if I bet $10 ... pot is now $14 and he needs to call the $10 which is 71% of the pot ... is this the correct way to think about using pot odds?

Scenario #2

Same hand but I get 3 callers instead of just the one. If I'm in MP and 2 players ahead of me check on the flop, how do I modify the betting amount to take into account that if I get one caller on the $10 ... the others see much better pot odds when the pot (and bet decision) gets to them?

Again, I am trying to learn how to use the pot odds when betting. I try to apply them when it's my turn to call/raise/check/fold. Thanks to all.
