The goal is in the heading 1-0 white wins! not a good puzzle unless you like to guess until the screen says that you are right, in my opinion. 20. a7 after it is "solved" for those that checked.
Confused

This is a puzzle that the end result is white wins... there are a few available moves each turn. try them all until you find the solution that they are looking for. there is no best move because this is like reverse chess, you are trying to lose!

Ok, I will give it a go. I think my terrible sense of direction is the major issue. I had a friend here, BILLG, that's what he thinks and as son as he said that.......yes!
I will try, thanx : )))

don't give up! sometimes a puzzle is only solved by eliminating the other choices. This actually can be applied to your games if you think of each move as a puzzle to be solved, you should consider each move that you can do whether you think you should. Consider your oppenent's moves this way as well :)
Anyone else get totally puzzled when you're confused? I hope this is the correct area for this forum. Some people get very upset. Being very careful. Feel free to answer folks : )
