Boris Alterman writes: "After 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5
the Czech chess player and problemist Karel Traxler discovered a daring move. Black completely ignores the threats against f7 and simply plays 4…Bc5! This looks like a horrible blunder, but is there a point that we are underestimating behind this move?
When we look at 4.Ng5 more carefully we can see the obvious problem – by playing Ng5 White has crossed the red line – don’t move the same piece twice in the opening. So, taking advantage of this inaccuracy, Black is developing his pieces in gambit style.
The Traxler counterattack has been the subject of scrutiny by amateur chess players for decades, but nowadays professional should pay attention too, because 4.Ng5 is becoming pretty common even in serious tournaments."
