I just learned some chess opennings, and I see some blunders, such as:
I think "5...Nc5" is a bad move.
next must be:
6. Bxc6 dxc6
7. Nxe5 (=> 1 pawn avantage for white)
Ruy Lopez, Berlin defence, blunder?
Sort:
Qd4
I'm assuming you mean 4...Bc5 is a bad move. Bxc6 dxc6 Nxe5 Is a blunder. Qd4 attacks the knight and threatens mate on f2.
that's right, Qd4 is the best.
By the way in general, 4. 0-0 is preferred for white rather than 4. d3. (if Nxe4 then d4, and if this pawn is taken, black tends to be in hot water after Re1, so in general white ends up taking on e5 and winning his pawn back).
If you are interested in Berlin defense, you can take a look here
@mariosuperlative :
what u say was true some years ago, but nowadays, when white wants to make something against Berlin, they rather play d3...
Because the Berlin endgame is a tough nut to crack...
