Full and Half Bet Rules

[costashark]

Please can someone give me a SIMPLE but comprehensive explanation (or direct me where to get one) of the half and full bet rules.

Everywhere I look I am only able to find the same generic explanation which misses some of the intricacies, please see below.

‘If a player goes all in with a raise rather than a call, another special rule comes into play. There are two options in common use here: pot limit and no limit games always use what is called the full bet rule, while fixed limit or spread limit games use either the full bet rule or the half bet rule. The full bet rule states that if the amount of an all in raise does not equal the full amount of the previous raise, it does not constitute a "real" raise, and therefore does not reopen the betting action. The half bet rule states that if an all in raise is equal to or larger than half the bet being raised, it does constitute a raise and reopens the action.

For example, a player opens the betting round for $20, and the next player has a total stake of $25. He may raise to $25, declaring himself all in, but this does not constitute a "real" raise, in the following sense: if a third player now calls the $25, and the first player's turn to act comes up, he must now call the additional $5, but he does not have the right to reraise further.

The all in player's pseudo-raise was really just a call with some extra money, and the third player's call was just a call, so the initial opener's bet was simply called by both remaining players, closing the betting round (even though he must still equalize the money by putting in the additional $5). If the half bet rule were being used, and the all
in player had raised to $30 instead of $25,then that raise would count as a genuine raise and the first player would be entitled to reraise if he chose to (this would create a side pot for the amount of his reraise and the third player's call, if any).’

I just can’t seem to get my head around it……… HELP!!!!!

Um...it's pretty simple. If a player decides to stick his stack in over the top of another player's bet, but doesn't have enough chips to double the bet in PL/NL, or doesn't have enough to make it 1-1/2 times the bet in limit, then it's considered a call not a raise. In the scenario outlined, if the third player just calls then the first player can't reraise, but if the third player raised over the full bet/half bet threshold then the first player can reraise, because now it is considered a raise.

this is wrong, the person who pushed all-in would have to have at least $40 for it to count as a real raise. If he pushes allin for an amount above $20 but less then $40, then the players who've already acted (that have put in $20), only have the option to call or fold. Hope that helps.

Ok, for example… the blinds are $50/$100

SB pays their $50, I am BB and pay my $100, all players fold around to seat 5 who makes a raise of $450.

All players fold round to the SB who raises to $575

Now here are the questions….

Do I, being the BB position and having not actually acted on the hand, have the ability to call and raise to a minimum of $675 or can I only complete the bet?

If I am able to call and raise, I assume that this open up the possibility of re-raising for the player in seat 5?

If I am only able to complete the bet, does this open up the possibility of re-raising for the player in seat 5?
