play what you think the refutation is and see what the comp moves are
or any other variation
a lot of times there is just something one is not seeing- especially a pin somewhere or whatever
the puzzles i run into that are duds are more like those where there isnt really a tactic- or a tactic that has two variations where there is minimal change in the “engine analysis”
post it up
I have found several puzzles with blatant mistakes. Just now I found one where the "solution" was to check the black king, which was on 8H, with the white queen by moving the queen to 8G, which was also covered by a white knight on 3H. Sounds great, except 8G was also covered by a black rook. So, queen checks, rook takes queen. How is this a good solution for white? I have a screen shot if anyone is interested
