Arnolio vs ianlawrencev

Well I havent played for while and it showed...I had black pieces in 15/10 match..opening seemed close but then he managed to open up my defense, isolate my king and pull him out...although the material and time was about even..Ian was checking my king with every move and my game was completely ineffectual,,,, by the 32nd move..I resigned...Next match will be closer, I think...If I made a few stronger moves this might not have happened...I believe I can defeat this opponent next time...
