The Ponziani is the main
aggressive/surprise opening I used as White when I climbed from 1600
USCF to eventually 2130 over about three years. My coach GM Alex
Wojtkiewicz (R.I.P.) suggested it as an easy way to trip up class
players who likely don't have time to study this somewhat obscure
opening and figure they'll just play it over the board if they encounter
it. Unfortunately for them, the "natural" moves are the wrong ones and
they can easily fall into some traps. This opening is also good for
online blitz and bullet games for the same reason/ ==========================================
Chess Lesson: The most common mistake - Grandmaster Smirnov
Notes by Grandmaster Igor Smirnov: As a chess teacher, I analyse my
pupils' games regularly. Of course, I analyse games of other players as
well. That's why I can tell you that there are a few most common
mistakes, which most of players make often. So in this lesson, I am
going to tell what the most common mistake is. =============================================================
