This is probably the single biggest thing that irritates me about online poker. Especially late in a tournament when people do it not understanding its hand for hand...
It appears that it is you that does not understand.
The most likely reasons when you witness stalling from some players during hand for hand, is the attempt to make the money by stalling so that they are not eliminated with their small chip stacks before the bubble.
Do you know what hand for hand is? There is no point stalling when you are at this phase, no matter if you have one single chip, the next hand will not dealt in any table if they are still playing. It is the stone bubble phase, it is usually requires a single player's elimination to get in the money.
It is totally pointless for someone to do it.
The thread creator here means the pre hand-for-hand phase. There is a major difference between those two.
