playing the computer may improve your skills
someone else can answer that better than me
but computers- especially throttled down computers play nothing like a human; it might as well be a different game imho
and, at the end of the day, how would you know if you were improving unless you play some humans?
i suppose the computer would have to slowly ease its throttling down as you improve but, eventually, it would be full strength and you would never win again
but, apparently, a whole influx of players are playing the comp all day
i guess i am in no position to answer- i have no idea- playing comp is not my thing
i use the comp to help me with tactics from my games and blunders
If I just play games against computer, it would be faster (perhaps half time) and hence double the experience gained for my time investment. The downside being that it’s less exciting.
Is this an approach lots of people take advantage of?
