The LCD Smoke Trick is one of the newer, arguably, exploits of the game that can give players an advantage.  Simply crouch and then physically move your mouse down in front of the smoke grenade's puffs or plumes and you want to look at the top of your LCD, or even CRT to boot.  You will see enemies much more easily hidden in smoke grenades giving you the all important advantage.

Tyloo shows us this trick used against Fnatic, who amongst numerous other top teams and players utilize as well, on de_dust2 during E-Stars Seoul.  It did aide the patient TB in allowing him to keep creeping up against the Swedes, especially the Rail defender, and he eventually opens up by picking off two Fnatic members to secure the gun round for Tyloo.

Despite its nature it has not caused a controversial uproar akin to crouch walking (aka bunny hopping or Russian walking) as seen in eSports' past.  Is this even an exploit or just a clever new trick for players to use?  What do you think?  Comment below and discuss amongst yourselves.
