living the e pawn to take, irresistible temptation ! Then, black will stay with a BIG HOLE in the center. |

2 pieces out, but no center. It will be easy to develop for white. |

Now we are ready for fight ! In order to place the f3 knight in e5 to provoke an exchange and open f colon retaking with f4, i need to take first the lsb to prevent a dangerous sacrifice in g2 |

so i have to defend e3, or cancel one of the two threats. I will choose this last option in order to go n developing my plan (open f colon ...etc.) |

|

will place the f6 knight in e4, then advance f7 to kick my e5 knight and go on on his plan (attack e3) |

|

oh ! what a nice calculation ! black is -3 anyway, and this was the best option in order to not to break the king castle. But this is ignoring the fact that two rook together are much more powerful, and even more in endings games.... |
