Some calculations
I have been able to reformulate my method of how to study openings in a way that it matches the exact way that I study tactics. This means that I can calculate how much work must be done to acquire a decent basis. A problem costs me 3 minutes at average To absorb a problem I need 20 repetitions at average There are 350 problems based on frequently occuring mates There are 350 problems based on frequently occurring tactics For my special weakness of knight moves, I use another set of 300 problems Each opening has 70 essential variations at average A variation equals a problem in how I approach it and requires the same time to absorb (60 minutes) I have 4 new openings 3x20=60 minutes to absorb a problem or variation. 350+350+300+4x70=1280 problems or variations to absorb. This totals to 1280 hours. With a study time of 3 hours per day, we are talking about 427 days. What do I expect after those 427 days? a decent level of mating skill a decent level of tactics a decent level of knig...
