Here are the answers to the week 2 Tesuji. . We want people to read the variations out for themselves so we will only be including the first move. It is important that you are able to read your moves thoroughly, so we encourage you to read the problem again even if you got the first more right. That being said the second problem can be difficult if you do not see black's second move, so if you did not solve it, we recommend you to treat it as a new problem. If you have any questions we also encourage you to ask them through the forums to foster any sort of related discussion. Feel free to check out some other threads and posts as well!
