Poker betting and raising question

MP1 has all actions available to him just as if it was folded around to him, assuming you mean that UTG has gone all in for $80 and not $280, where I suspect you actually mean the latter

then what is the legal minimum betting amount for MP1? is it $200? or $280?

Assuming the all in was $80, which is less than 1BB, that all in has no effect on any subsequent action. Other players must still call the $200 BB and a min raise would be to $400. If the all in is $280 then obviously subsequent players must either fold, call the $280, or raise. I’m not sure if the min raise would be $400 or $480 though. I’m leaning toward $480 but I’m prepared to be told that I’m wrong.

"I’m not sure if the min raise would be $400 or $480 though." - This one. I hope some experienced poker dealer or player will clarify that.

Per TDA rule 43 the minimum raise amount is the largest legal bet or raise of the current betting round. The TDA rule set also includes an example for rule 43 very similar to the one in the OP. The correct minimum raise following an all in of 280 with a bb of 200 is definitely 480, not 400. The current action is 200. The largest legal bet or raise is the BB of 200 since the all in for 80 more is not a legal raise. Therefore the min raise is the pending action of 280 plus 200 or 480.

That is assuming that you are playing in a tournament or a cash game that uses TDA rules. Many card rooms and casinos do use these rules, but not all. Always make sure you know the rules used by the game you are in.

I suggest we follow the right "words", "bet" is different to "raise". Player cannot make a raise without the previous player making a bet. What I mean here is the "Opening Bet" - the initiator.

In a strictest sense : if the UTG(OP post) Goes All in $80. "I don't have any idea what is the term used by poker dealers in this situation." Because as we can see it is an "ALL IN" situation. I can't assume that it is a bet or a raise. IFAIK some called it "all in wager", not very sure of this.

If I am not mistaken, you are implying the 50% rule right? Usually the 50% rule is applied in Limit Hold Em and Tournaments. What if we will not use the 50% rule? what rule or common house game rule? Any suggestions? e.g will the Robert Rules of Poker apply?

If UTG truly goes all-in for less than the BB amount, he is simply calling all-in. He is not raising. The bet is then to the next person who has the same options available as if UTG had folded or called a full BB. He can call, raise to 400 or more, or fold. If UTG actually had 280 and goes all-in, this is not a legal raise - and has nothing to do with the 50% rule. A legal raise in no limit must be at least equal to the previous raise amount, but it wouldn't matter in this situation. Whether or not a bet is a legal raise has implications for whether or not it reopens the betting to the original bettor. In this case, he would be the original bettor. Everyone who has not acted yet (in this case ALL players) still have all options open. They could fold, call 280 or raise - and according to previous posts, the minimum raise would be to 480.

Thank you for this valuable information 😀

Just some little clarifications.

If Blinds: $100 / $200

SB: posted $100
BB: posted $200
UTG: Goes All in $80
MP+1: ?

If MP+1 decided to "CALL". Will MP+1 call $200 or is it $280?

Sorry for my bad reading comprehension and grammar, English is not my mother tongue 😀

$200. The minimum amount to call in an unraised pot is always equal to the big blind.

UTD's all-in for $80 is not a raise, and he can only win $80 from SB, BB, and anyone else who calls or raises the $200 BB.

Let's assume MP+1 calls and everyone else folds, including the SB.

The main pot is now $320 ($80 each from SB, BB, UTG and UTG+1) and can be won by BB, UTG and UTG+1. The side pot is now $260 ($120 each from BB and UTG+1 and $20 from SB) and can only be won by BB and UTG+1. Any further bets by those two players add to the side pot, to which UTG has no claim on.

$280 is not even a legal amount for MP to bet in this case (unless it’s his entire stack and he is all in for $280). MP has three options - fold, call $200, or raise. If he raises the minimum raise would be to $400 (200 current action plus 200 as the minimum raise amount, the largest legal bet or raise for the betting round). In this case the $80 all in has no effect on subsequent players’ options.

Thank you 😀. Very appreciated. You guys answered my questions, its very hard to find some resources especially situational poker scenarios, I do not have a professional poker dealer friend, and this advice you guys gave will give transparency and clarity to the never ending arguments with my friends.

Very much appreciated all of the help that I've learned here.
