The chip glance simply refers to a player looking down at their chips before the action gets to them once the flop has been dealt. This brief glance down nearly always means that this player is intending to bluff and has missed the board. The reason that this glance usually indicates this is that the player subconsciously realises that their hand cannot win the pot, therefore the only option available left to them is to bluff with their chips, hence the glance down.
