Two pawns for one minute
There was a phrase that was very common in those sessions: "Sacrificing a pawn for a minute!". Most often, it meant that you just blundered something, but the opponent could never be 100% sure if it wasn't indeed a proper sacrifice. He would spend time checking variations and - lo and behold! - he was indeed behind you on time! We all strongly believed that one minute was more important than a pawn in blitz. In fact, I still do

Recently I was playing in a strong blitz tournament here in Singapore and in Round 5 I had to rely on this formula as early as early as 10th move. Actually, things were even worse than usual for me, as I followed a theoretical pawn sacrifice by blundering another pawn on the very next move. So there I was, two pawns down for a few extra seconds on the clock and a semblance of attack. In the end, it worked out very well and made for a fun and lively blitz game that I would like to share.
