The idea is you should gain points for the patterns you know, and not lose too many for the ones you have to work out. Over time you build up pattern recognition and answers become obvious.
If you have to work it out more than just checking then you don't know the features of the position well enough.
Focus on the tactics, the scores will come.



Ok - new player yes I suck at tactics but I'am getting better.
I've been dancing around the 1000 - 1100 mark and everytime I hit 1100 I seem to get unlucky with a sequence of abstract puzzles. I managed to hit 1100 again today and the first puzzle after I wanted to not blunder so I took my time and got it correct first time and got -4.
Boom back under 1100. Feeling pretty demotivated right now.
