The point of doing tactics is familiarizing with common patterns, in order to not have to figure them out during an actual game (bonus points for seeing them used against you!). If you immediately spot a pattern, move right away, otherwise take your time to figure out what's going on.
More importantly, realize that chess.com tactics rating means absolutely nothing, only ever do tactics to improve, gaming the system in order to maximize your rating is a boring and useless exercise.
I'm working on easier tactics problems, trying to do them over and over.
My question is, should I be taking my time, making sure I have the right answer before moving, or should I be trying find the patters quickly? I've read arguments for both sides, just not sure what the best way to go about it is.
Thanks for any advice.
