Puzzle #226 solution:
Game Steinitz - Amateur. James answer was very good:
a) what makes the position imbalanced is the material: White has a Knight + Bishop for a Rook + pawn. This is good in the middle for White and it could be good for Black in the endgame
b) material is equal;
- White's King is in the centre, but not really anything is attacking it;
- Black's King castle is attacked by almost every White piece;
- White pins the g7-pawn with his Rook;
- Ne8 and Bf6 are defending the pinned g7-pawn
- Black has a Rook + Queen battery on the open c-file attacking nothing;
- Black's f8-Rook can be counted as doing nothing judging from its disability to move right now;
- White has an isolated d-pawn.
White's plan: should attack right now; come up with a way to win or trade the Knight + Bishop for at least a Rook + pawn to re-establish the balance.
Black's plan: should play defensively to proceed into endgame where he could have better chances.
