2009-11-05 21:05:40UriBlass1888not overrated 1.b4+ is the first move to think about found 2.a4 but too much time and lost rating points. 
2011-02-09 21:16:58Misha19981802I played 1.b4+ without thinking. 
2017-03-16 15:24:09grom4318451.b3 threats Qa4# and/or a4 with Qb5#, but missed the immediate 1.a4 which is game over.
