A person playes 15 tables or OR more ?

I was playing on a reg site and was watching a player play
when I looked for him again it turns out he was playing
20 tables at once with $25 on each tabl HOW IS THIS POSSIBLE?

Such people, I call "chip wasters." They are addicted to playing poker. They do not win all the open games they play ... and then there are the "groups" who gather someplace a series of tables and swap screens or dash back/forth giving buddies at the terminals tips. In which case, you're not playing against one party. What is quite rude about multiple table play is the delays caused by such people at the table wherein you are seated. Whenever you detect collusion, report the IDs, the table, and the hand sequence. They will admonish/pull such IDs, as collusion is not permitted.

The person is most likely nut peddling. 20 tables, 40 hands per hour so 800 hands per hour. You will get AA,KK 7.23 times per hour. Basically it is a player that has a simple set of rules that allows instant decisions (shove or fold) nothing real fancy.

it actually takes a lot of skill to multi-table, a lot of advanced players cant do it, your practically playing with no reads if your 15 tabling, those who can pull it off can increase their earnings % dramatically, its a real advantage to know if an opponent is multi-tabling (i check), you can exploit their weak read

i think its more than 40 hand/hr usually. When I play 6 tables of FR you get over 300 hands /hr most of the time and same for 4 tables of 6 max

practice

Wrong.
Wrong.
They get what's in their time bank, if they don't play in time it folds them.

Multi-tabling is RARELY collusion. How can you collude when managing 20+ tables? I play 12 tables. Most multi-tablers play with a HUD to assist them in reads, so their reads aren't really that weak either. Mostly the multi-tablers seem to be the most solid imo (or maybe I just notice them the most since it's more likely they show up at my tables).
