Problem Statement

A graph is called 7chip7-chip if it obtained by removing at most three edges that have no vertex in common from a complete graph with seven vertices. Consider a complete graph GG with vv vertices which each edge of its is colored blue or red. Prove that there is either a blue path with 100100 edges or a red 7chip7-chip.
