Not sure how the opening training works. I like it a lot, since it shows me a lot of openings I never play or see. On the ones where it asks for four strong moves I often find three, which I think is pretty good for not knowing the opening.
Just a quibble: do we get partial credit for that, or are we scored pass/fail on getting all four strong moves?
I find the opening training works not so much accurate and it's getting very quickly boring to me. I prefer do some puzzles.
I prefer to do, sorry for my bad English.
It doesn't give partial credit exactly. Meaning if you give a poor move immediately, you get the same deduction as if you gave three correct and one bad choice.
But there are often several moves that are passing moves. Usually if the puzzle asks for 4, you can probably choose 6 that would count as "good" moves. Also, there are a few puzzles that will have "okay" moves, where you can play a move and if it's not one of the top choices, it will not give credit for it. But it will not count it as wrong since the move doesn't necessarily lose any advantage.
