Floor!
Level 4
: 100/200, 25 ante
“Floor,” called the player facing a bet on the river from Russia’s Gaik Karabakhtcian on a board reading . When the floor arrived the dealer explained what happened. Karabakhtcian had announced a bet with a blue T5000 chip in his hand, said “four,” and tossed it across the line. The floor responded, “Ok, I’m going to rule that as a bet of four hundred.” Karabakhtcian was surprised by the ruling but when his opponent tossed the 400 into a pot worth several thousand he was at least relieved to see his was good enough to win as his opponent mucked.
There are a lot of rules in live tournament poker and it pays to know them as bet you can.
