I noticed that when playing Jinja City Grid in the faceless environment of Jinteki.net, it is much easier for the corp to hide what they drew. In meatspace the situation is much different. I played in a small tournament and I was genuinely getting A LOT of information what the corp drew when Jinja City Grid was rezzed. I could immediately read from the player what type of card they drew even when they drew ICE but did not use JCG to install it. While it made my information accurate I was not able to leverage it to my advantage due to my runner not having necessary tools to get in to.
You really need to “act” differently when drawing with a rezzed JCG as the corp. I wouldn’t allow installs after the drawn card has been added to HQ as after that point it is impossible be sure that the installed card was in fact the one that was drawn.
Not discussing the actual card ability I am more interested in the nuances in playing the card in meatspace. How do you play around or with, the body language information that this card creates?
