Yesterday I played the best Titled Tuesday of my life! I scored 7 out of 10 with a performance rating of 2596 and got to play the strong GMs Tigran L. Petrosian (winner of Olympic gold with Armenia in 2008 and 2012) and GM Hrant Melkumyan (Europea blitz champion 2011). My play was not very good but resilent. A few tactics from my games.
White to play and win
Black to play and win

Position after 13... Nf6. Is 14.b4 a blunder or a good move?
