White recently lost the right to castle after Ke1-f1. Black has an advantage in development and can look forward to developing the rest of the pieces quickly. On the other hand, black's king is not perfectly placed on h7 and white does have ideas how to regain some harmony among the pieces (Qc5-d4, h2-h4 and Nf3-g5). Black senses that white is in big trouble. But how should black continue? To use this problem for training purposes, please calculate all the variations and write them down on paper before making the moves on the board.
