The nature of the blind bet in poker is to ensure that every hand will have action. Blinds, then, could just as easily be called ‘bait,’ as in most scenarios they are there to give a manner of definition to the action in a handsomething to vie for in raising and reraising, even when in the end they are often nominal comparatively to chip stacks and average pot sizes.
When a player raises the blinds at the casino online, then, they are essentially attacking. Especially in late position, when there have been no other bets in front, players will often make raises from or near the button under the assumption that minimally raising in position will make the blinds, who most often have nothing worth playing, lay their money down with no kind of resistance.
Calling a raise from the blind, especially with moderate hands such as connectors or etc., hands that might not be played from other positions, is considered ‘defending the blinds’: putting yourself out there because you already are partially invested. Not defending often enough, in these positions, can result in more aggressive players attempting even more regularly to steal, whereas defending with a wider range of poker online hands might discourage them from attacking with weaker holdings. In general, it seems best to be moderate but prudent in these situations, defending when necessary, but not simply out of spite.
