Yes and no. It's okay to eliminate the most likely option. If they like to combo extend why yes I will spam (high) counter holds (if they are baiting for throws, low counter). Another situation are pokes from long range, most characters only have 1-3 decent attacking options.- Learn to hold on REACTION rather than PREDICTION. (this is easier said than done and takes time)
Only if you wish to learn. In a tournament setting, you should just do what you do until something stops working out in your favour. React by changing the tool that's not working for you. Until you're at a higher level of play you should focus on yourself. When you just do what you do without thinking with perfect timing, spacing, etc, then you can start looking at what your opponent is doing.- Do NOT restrict your focus on your actions alone. Focus on your opponents actions as well.
Play your game, not theirs. You playing your game is stronger because you've spent more time with it.
Online-offline just make sure you are supporting the scene. Competing in an tourney is worth more Kudos than just playing online. More Kudos to those that travel.
There is a lot of heat to the online-offline topic.... Welcome to DOA.
