Ranges / Under the Gun 20bb
Under the Gun push/fold chart - 20bb, 9-max
Under the Gun open-raises 10% of hands here at 20bb effective (14 of 169 starting hands go in at full frequency). Under the gun opens first with the whole table still left to act behind it, so this is the tightest opening range at the table.
At this depth you're deep enough that a few of the weakest hands here play slightly better as a raise you can fold to real aggression than as a flat shove, though shoving stays close to optimal for the bulk of this range.
