check sometimes, shove sometimes. in villain's eyes, you're not shoving 99-JJ here and the board has 2 baby cards which could have hit you hard. he has reaaaaaal trouble calling you with 99-JJ here and possibly KQ and AQ. The only way to win this hand against a wide villain's range (99+ KQ+) is to shove here and if he makes a hero call with 99-JJ and KQ and even AQ, as KK-AA can fall under range, you still have outs to fall back on. In short though, if you shove, only hands that snap call are KK-AA and QQ but you fold out a lot of marignal hands that beat you on showdown.
