Multi-tabling is normally the reason most people give for taking up their time or time-bank before calling(raising, if u want to be pedantic) with the obvious best hand. For the record, it was the guy playing Matt who accused him of it, not me.
3 hands later the same guy WAS slow-rolled by the eventual winner who hit trip 10"s on the river. He pushed all-in and the other player waited until the last second before calling with the nuts.
