In this chess training video, we will study the subject of lagging pawns in the semi-open line, which is one of the most important mid-game issues in Chess. We will see what openings and defenses it consists of and better understand the ideas underlying the opening (or defense) and the right strategies in the mid-game. We will determine and make better plans.. We will learn ideas that also benefit chess from checkmate architects such as Bobby Fischer, Jose Raul Capablanca, Max Euwe.. I believe that it will be useful for chess lovers. We will be happy if we can contribute to your success, checkmate architecture channel.. See you in our next training video.. goodbye.
