Colle System Challenge KID

Black has two promising King's Indian Defence ideas to crack the solid Colle System. One strategy is to play an early ...c5 to attack d4 and hold back ...e5. The alternative is to play an early ...e5 along with ...f5 (after moving the Nf6 away) and hold back ...c5. It's not easy if White is determined to maintain a symmetrical pawn formation.

Ray Haines played the Colle System vs the Kings Indian Defence of Roger Morin in the first round of the Potato Blossom Festival. Ray Haines organizes this event each July in the northeast corner of the United States. This year the tournament was won 4-0 by Leonardo Cui of nearby Canada.

Haines and Morin face each other a few times each year, so they are familiar with their styles and openings. Black chose to play both 7...c5 and 10...e5. The d-file was opened by 12.dxe5 dxe5. Both sides missed chances for an advantage. They drew in 42 moves.
