Hello,

my engine have at the moment no trade code. I thought thats not so importent.
For example its funny if homer give a knight+pawns vs rook.

But this evening i can't believe what happend:

Fruit vs Homer:
FEN: r2q1rk1/ppp2ppp/3bb3/2nNBB2/8/8/PPP2PPP/R2QR1K1 b - - 4 13

(I'm sorry, but i have no glue how to post this as diagram and which software).
A little HOWTO/Hyperlink would be nice)

Homer play here Bxe5 with +1.6 for black.

If we are analyze we see that black will be lost after:
Bxe5 Txe5 Qd6 Qd4 Nd7 Bxh7+ Qh4+ Kg8 Ne7+ Qxe7 Qxe7 Nxe5 Qxc7 (allso homers pv)

I realize that i need more as 16 ply here to see that black lose.
All capture moves expect Nxe5 will be not extended in my engine.

So its very importend to have trade knowlege.

Maybe this is a interessting position for other little engines.
I know that the big engines don't capture here.
