Exploiting Opening Blunders
3 i alwats eat e5 , ie knxe5 just to pass on a chess lesson to my opponent the f pawn is not a good early defender of e5
I don't have time to actually make something for this, but one of the funniest trap checkmates is in Wayward Queen Attack...
1. e4 e5
2. Qh5 Ke2 (looking at this afterwards would make it seem really dumb, but I think there's a chance your opponent will play this)
3. Qxe5#
Also, 2. Qh5 g6 loses to Qxe5+ then a free rook. You sometimes have to do a bit of work to dig your queen out though.
And a quick copy and paste from a really funny one that I actually managed, too:
1. e4 Nf6 2. Nf3? { (0.29 → -1.14) Mistake. e5 was best. } { A05 Zukertort Opening: Lemberger Gambit } (2. e5 Nd5 3. d4 d6 4. Nf3 dxe5 5. Nxe5 c6 6. Nf3 Nd7) 2... Nxe4 3. Ne5?! { (-0.98 → -1.79) Inaccuracy. d4 was best. } (3. d4 e6 4. Bd3 Nf6 5. c4 c5 6. dxc5 Bxc5 7. Nc3 b6) 3... f6?? { (-1.79 → 12.38) Blunder. g6 was best. } (3... g6 4. d4 d6 5. Nf3 Bg7 6. Bd3 Nf6 7. O-O O-O 8. Re1) 4. Qh5+ g6 5. Nxg6 hxg6?! { (12.40 → Mate in 1) Checkmate is now unavoidable. Kf7 was best. } (5... Kf7 6. Ne5+ Ke6 7. Nf7 Bg7 8. Nxd8+ Rxd8 9. Qxh7 Kf7 10. Qxe4) 6. Qxg6# { White wins by checkmate. } 1-0
Also, a variation with a bishop sacrifice:
1. f4 { A02 Bird Opening } f5 2. Nf3 Nf6 3. d3 Nc6 4. e4 fxe4 5. Ne5 Nxe5 6. fxe5 Nd5 7. dxe4 Nb6 8. Bh6 gxh6 9. Qh5# { White wins by checkmate. } 1-0
