Most importantly, it is an <strong>ideal repertoire to play for a win with the black pieces<\/strong>.<\/p>\n<p>And as Robert puts it himself: <strong>\u201cNo boring lines at all.\u201d<\/strong><\/p>\n<h3>What is the Triangle System?<\/h3>\n<p>The Triangle System arises after the moves:<\/p>\n<p><strong>1.d4 d5 2.c4 e6 3.Nc3 c6<\/strong><\/p>\n<p>Black starts with a sound developing setup, controls the center, and then enters a flexible structure that can lead to a wide variety of positions.<\/p>\n<p>One of the reasons Robert considers this system so interesting is that it can lead to many different pawn structures. In this course, he begins with the critical lines based on <strong>e4<\/strong>, covered through the <strong>Marshall Gambit<\/strong>, before moving on to the <strong>Nooteboom Variation<\/strong>, Catalan-type structures, <strong>4.Qc2 systems<\/strong>, <strong>Stonewall structures<\/strong>, and the <strong>Carlsbad structure<\/strong>.<\/p>\n<p>The goal is not simply to equalize. As Robert explains, this is a repertoire for Black players who want to <strong>aim for more<\/strong> and fight for winning chances from the opening.<\/p>\n<p><img loading=\"lazy\" class=\"aligncenter \" src=\"https:\/\/videoapi-muybridge.vimeocdn.com\/animated-thumbnails\/image\/bb2b7b9d-21c1-4c33-93cc-4256f2df5f4d.gif?ClientID=sulu&amp;Date=1780432680&amp;Signature=daeac5eec388fe579e186c2e02b2e158e65153dc\" width=\"547\" height=\"309\" \/><\/p>\n<h3>Learn from IM Robert Ris<\/h3>\n<p><strong>IM Robert Ris<\/strong> is an <strong>International Master from Amsterdam, the Netherlands<\/strong>.<\/p>\n<p>In this course, he shares a complete repertoire against <strong>1.d4<\/strong> based on an opening he has personally played himself.
