<

4..g6 5 Nge2 Bg7 6 Nd4 cd4 7Qf3! 

Here Black can play 7..Nh6 or 7..Nf6 but the most natural human move is 7..e6?! which leads to the trap White has set up !

7..e6?! 8 Nb5 d6 9Qa3!

Black has to defend d6 and play 9..Ke7

White has exploited the weaknesses of dark squares after 5..Bg7 by targetting c7 and d6 playing Nb5 as Black didn't have time to play a7-a6.

after 9..Ke7 10c3! white is better. You Hifan won against Pia Cramling in 19 moves.

Note that Black can try 8..d5 instead of 8..d6 but White has 9Qg3! with Nc7+ winning the exchange.
