E12 Queen's Indian: Unusual White 4th moves, 4.a3, 4.Nc3 Bb7 5.a3 and 4.Nc3 Bb7 (1.d4 Nf6 2.c4 e6 3.Nc3 b6 4.Bg5 Be7 5.e3 Bb7 6.Nf3 O-O 7.Be2 d6)

This opening should have been in this blog earlier but as the source of openings I only used in the past did not recognize E20 Nimzo-Indian Defense #2, this did not happen before I started to check these openings from Chess.com as well. The game below was played in a team match called Happy New Year 2015 Romeo and Juliet vs Kasparov Chess Club !! I played on board 11 in this match for Romeo and Juliet and won both of my games against Jhopes on time. This is a match that is played on 62 boards and the current score in it is 89 - 33 in favor of Romeo and Juliet which means that we have clearly won the match already and only need to wait to get the official win after all the games in the match have finished. I have added one mate in one, one mate in two, one mate in three, one mate in four and one mate in six puzzle today.
