Pot odds - when to use flop-to-turn?

Hi vicePlayer,
Welcome to PokerStrategy.com

Rather than try to explain it in my own words, I refer you to this article in our strategy section:
https://www.pokerstrategy.com/strategy/various-poker/basics-odds-and-outs/

Look for a section called "Can I profitably play my hand" or similar.
There is also an article about implied odds, which covers those situations where you should continue even if the odds are slightly against you.

If you're new to poker — and even if you've played a bit — I suggest going through the steps in this article:
https://www.pokerstrategy.com/strategy/bss/no-limit-holdem-lessons-overview/
It is a fairly concise beginner's course in No-Limit Hold'em

If you're not playing online yet — and perhaps even if you are — have a look at the bonus offers or perhaps one of the free money offers.
There may be some money there to get you going.

All the best,
VS

Thank you, VS. From some more reading it appears to me that the answer kinda depends: in simple cases when someone goes all in on the flop or have barely any stack left after flop, we can easily rely on flop-to-river odds. But if they do not go all in and still have a large stack, a lot depends on whether they bet more on the turn and how much more. If they do not bet more on the turn, flop-to-river would have been the right odds to use. If they do, the right odds would fall somewhere between flop-to-turn and flop-to-river odds. So it's kind of a guessing game there then?

You said it all in the first line: It depends
There are so many factors to consider that it makes poker a very complex game, when in reality it should be so simple.

That is why study is so important — not just study, but slow, incremental increase in skill. You cannot learn it all at once.
Start small and grow.

Best of luck :gl:,
