The Single Corner opening with 11-15, 22-18 is very popular and full of interesting play, but sometimes a seemingly reasonable and natural looking move will singe a player's fingers, so to speak. We'll look at one such situation in today's original study.
To set the scene, here's the run-up, without commentary.
Here's the position as it now stands.
White should have played 17-14 but didn't, and it's a win for Black, but how? Could you have drawn with White had you played 17-14? Black still would have an edge and the draw is not easy.
