1st move is knight takes e5 pawn????? what happens if black knight takes the white knight..... What is white next move ???????????

abo_tamem_1012 in #134 presents a brilliant example where Li 2320 uses a devastating Queen sacrifice to defeat Huang Qian 2416.

Huang Qian has two choices, capture the queen (best choice) or capture the bishop with the g2 pawn.  If he does neither, Li's queen will capture g2# with his next move.  If white captures the Bishop, Li's ... Nf4 will enable Li to move the queen to g2# on the next move.  So Huang Qian captures the queen, but now Li's ... Nf4 threatens ...Nxh3# on the next move. Huang Qian delays that one move with Ng6, but Li captures that knight with his bishop, and Li has no further way to prevent ...Nxh3#.  Brilliant!
I hope I learned from this, because I didn't see it on my own.

Why couldn't you keep the queen and try with Ne7?

jogd in #171 proposes as a solution to the daily puzzle:

1. Ne7+  Kf8,  2Nxc6

That does put white a knight ahead, but black immediately responds with
2. ...  Qxe4, and white's advantage is very slight.

Better to capture the knight and force a queens trade.

Sacrifice!!!!!!!!!!!!!!!!!

In the Beltran vs Marin game (posted by abo_tamem_2012 in#161,  white could have extended it longer, but not prevented the checkmate:

1. ...   exf3,
2. Rg1 Qxe2,
3. Qf1 f2+
4. Qg2 Bxg2+    (4.  Rg2  Qxf1#)
5. Rxg2 f1=Q+   (5.Kxg2  f1=Q++,  6. Kh1   Qeg2#)
6. Rg1  Qeg2#
