Is a reraise allowed?

Unless I completely don't understand, player C only raised 80 on top of the 100.

Agree with venice.

[QUOTE="TDA"]47: Re-Opening the Bet.

A: In no-limit and pot limit, an all-in wager (or cumulative multiple short all-ins) totaling less than a full bet or raise will not reopen betting for players who have already acted and are not facing at least a full bet or raise when the action returns to them. If multiple short all-ins re-open the betting, the minimum raise is always the last full valid bet or raise of the round (See also Rule 43).

B: In limit, at least 50% of a full bet or raise is required to re-open betting for players who have already acted. See Illustration Addendum.

Since B raised $88, and C raised $80, B may not reraise. A, however, is facing a full bet (quite a bit more, in fact), so A has all options open.

I don't see were you get the C raised $92. It was $100 to him with a $88 raise. $180-$100 = $80 and $80<$88.

B cannot raise as C action is not a complete raise and thus B would be raising himself.

Seems like OP is subtracting the original bet of $12 from the second bet of $100 for some reason: $180 - ($100 - $12) = $92

The math is obvious but the logic seems illogical. Iow, the some reason seems nonexistent to me.

Player B can not reraise unless that room has some odd house rule. The last all-in was $80 over an $88 raise which is not a complete raise so action is closed once A calls.

In NL games the rule is that in order to re-raise you have to make a raise that is greater than the last bet/raise. In this case the raise by Player B was $88 so Player C would have to make it >= $188 for it to be considered a re-raise.

However if there had been a player D who went all in for $188 (or more) then that would be considered a raise of Player B's raise. So if player D went all in for $201 then the raise size would be $101 (i.e. player A or Player B if they wanted to raise would have to make it $302).

In a LHE game the rule is different. If a player goes all in for half the bet size or more then it is considered a raise. Otherwise (if they went all in for less than half a bet) it is considered a call. So if you are in a 20/40 LHE game on the turn if Player A makes it $40 and Player B makes it $80 and player C goes all in for $100 then it is a raise of Player B's raise. And player B is allowed to re-raise again. If player C goes all in for $90 then Player A could still raise to $120 (wow... Maybe its $130 that player A can raise to --- I just don't remember...) but if Player A calls then Player B can only call (or fold).

What happens sometimes in a NL game is that if there is a player who usually plays LHE (or used to) and thinks that if an all-in raise in the NL game is greater than half the last bet/raise then it should count as a raise. Sometimes it is the dealer who makes that mistake. Though now that LHE games are virtually non-existent its less likely...

I actually don't know what the rule is in PLO. I would assume it is the same as LHE so that if an all in bet is half the size or more of the prior bet/raise it would be considered a raise. Otherwise its just a call.

Pot limit follows the NL rule for this matter in TDA:

Thanks Dinesh!

My assumptions are pretty much always wrong...

I also learned something else. My thinking was that if there were two all-ins for less than the full raise that the total would be the new min raise size.

So in this case if Player A opened for $12 and player B made it $100 and Player C is all-in for $180 and Player D goes all-in for $250 my thinking would be that the min raise size would be $150 for Player A & B. But boy was I wrong. It would be still be $88 so Player A could make it as low as $338. LOL (I don't really ever click it back in a live game)
