{Let's evaluate the position a bit. Black's surplus pawn is
 compensated by White's advanced development. But if White is
 wasting time this advantage can easily fizzle because Black has
 already a rook on the open g-file and also a bishop on the diagonal
 a8-h1, both targeting the critical field g2. For the time being
 Black's king is stuck in the middle of the 8th rank because
 0-0-0 doesn't look healthy due to the open c-file. White's
 knights are active and look dangerous. Nevertheless can White
 really win here?}
