Hello,
the position Shredder vs Quark after 1.e4 e6 2.d4 d5 3. Bd3 de4 4.Bxe4 Nf6 5.Bf3
c5 6.Ne2 Nc6 7. Be3 Qb6 8. Nbc3 is very interessting. Quark takes the b pawn
with Qxb2 and lost the game :(.
It would interesting for me which engine don't take the pawn ?
My own very very joung and still stupid engine Homer don't take the pawn :) But
shows terrible pv's. Perhaps thats normally because my qsearch is very easy and
bad and don't check checks or can't see mates in the qsearch:
cheers,
Daniel
