Check Mate is Enough!
Some times we are looking for a longer solution, when the answer is very short. Look at the last few moves from a game in which I have just beaten Ailanhakki - the full game can be viewed here. I almost fell into the trap of capturing an easy pawn - after which I probably still would have won, but I was lucky to avoid a lot of unnecessary moves. More comments inside the few moves of the game below. (Sorry, most of the comments are gone, I don't know if it's me or this editor...)
Technical: I went to http://www.lutanho.net/pgn/pgnviewer.html (LT-PGN-VIEWER) to get a FEN string of the board at the point where I would like to start. It does not seem to word pasting a FEN string here. However I found that you can navigate to where you want to start in the game and then click "Set Begin" in the game editor.
