Betting structure in Hold 'em

I'm hosting a small tourney tomorrow night, and I'm sure the rules we use are wrong!

With blinds of, say, 25/50, what is the minimum bet after each addition to the table? (flop, turn, river) We play a minimum of 50 each time...???!

Format is NL Texas Hold 'em tournament.

BTW Is the answer the same for a cash game?

you're using the correct rules. the min bet is always equal to big blind and the min raise is 2bb. this is also true for cash games.

Does the minimum bet not double after the turn and stay that way for the river?

Thus in a 25/50 game, the minimum bet preflop or post flop is 50, whereas after the turn and river it's 100.??

This is correct. And the minimum raise is equal to the minimum bet for each street, so a raiser would be putting in 2 bets which is a call and 1x raise.

No, the first bet only EVER has to equal the big blind, it can be more, but it can't be less, and that's for all streets. All raises must at least double the original bet, again, no more, no less. In a LIMIT tourney the bets double on the turn and river, but it's no limit, so the only rule is that you must bet at least the bb.

I stand corrected. I play mainly limit.

Cool. So we were, in fact, correct? 25/50 blinds in NL hold'em is a minimum bet of 50 post flop, turn or river...

Gotcha! Thanks!

Min. Raise is 2 times the the previous raise. So let's say that the blinds are 25/50 and some one raises to 150. You must raise to a min. 300.

Not true. If the big blind is 50 and someone raise to 150, the amount of the raise is 100, so the re-raise must be to 250, NOT 300. A very common error.

In any LIVE game, the first rule is - Keep it simple.

Follow the basic rule that any raise has to be at least the big blind in any situation. This will keep your game simple to follow and more enjoyable for all.

Exemple in your case, 25/50 blinds.

First raise makes it to 150,
Next player would be able to re-raise to a minimum of 150 + BB = 200
Next one 200 + BB = 250 minimum
Etc.

Pass the minimum, the raise could be any combination of the smallest chip at the table. Hence, the first raise could have been 101 ( 50 + BB + 1 ) if you have $1 chips at the table.

^^ This.

If the 150 opened the betting on the flop, then anyone wanting to raise would have to make it at least 300 (150 bet, then at least 150 more).

But pre-flop at 25-50 blinds, AG is correct.

Some people play a simple "double the bet" format just because it's easier (some of the bar games I deal use this - path of least resistance, seeing as how people drinking and doing math at the same time just causes too many hassles), but the above rule is the 'official' one.

And yes, the answer is the same for a cash game.

Wow! That's fairly complicated even without the addition of a few 'tinnies' to calm the nerves.

Always good to learn the right way though. It's so easy to perpetuate an error simply because you believe it's correct....

Thanks all!
