Learn How to Fork: Decisive Material Gain
This puzzle comes from the Nimzo-Larsen Attack, Modern Variation, and it shows how a single tactical shot can turn an opening position into a decisive material gain. The key idea is that active queen play can exploit an undefended piece while also creating a forcing check. In practical terms, you should always look for loose pieces, overloaded defenders, and checks that improve your position while winning material. This is classic opening tactics: fast, forcing, and punishing development errors.
