14:32, too hard
ReplyDeleteToo slow shambo. I expected you to finish in around 10 minutes max.
Delete6:59.This is a stunning classic.Definitely in the harder category.
ReplyDeleteI was slightly disappointed to have seen the tip about the quad before I solved this classic.Wish I hadn't seen it.I wanted to solve and find it myself.
The solve is anything but trivial even after the 2 quads as it involves a difficult and nice step after that too.This is your best classic in the blog.
Thanks kishore. You made my day with your comments. I must say , you solved super quick.
DeleteTook a long time on this one. I was trying too hard to find a logic. What is the quad logic Kishore is mentioning?
ReplyDeleteIt was a tough one. Have whatsapped you about the quad logic.
