Sicilian Defence Qxd4 or Nxd4

Do you play 4.Nxd4 or 4.Qxd4? You have a choice in the Sicilian Defence as White after 1.e4 c5 2.Nf3 d6 3.d4 cxd4. Which recapture on d4 is better? Black has a playable game against either. Probably 4.Nxd4 is better, since 4.Qxd4 can be attacked by Nc6. When White delays 3.d4, the added time to develop improves Black's chances.

When Ray Haines played the Black side of a Sicilian Defence, his opponent "Hro61" temporarily held back 3.d4 for a couple more moves. After 5.d4 cxd4 White chose the unusual move 6.Qxd4. This supported the tactical thrust 7.e5, but the resulting position would only lead to equality.

At one point White did develop a good position and a strong attack. When White missed his chance on move 16, Black took over. Ray Haines won the Exchange and began his own attack. The players had bishops of opposite color. While they may lead to drawish endgames, they favor the attacker in middlegames. Haines demonstrates that his attack on the dark squares could not be stopped by White's light squared bishop.
