I'm not convinced about "White gets a clear advantage with 3.cxd5 Nxd5 4.Nf3! Bf5 5.Qb3." There are only 5 games in Chesslab with this line of play after 1997. White won in 4 and had a draw in the 5th. Crafty version 19.19 rates this as a slight advantage for white with an evaluation of +0.10 after 10 minutes of calculations.

The alternate of 3.cxd5 Nxd5 4.e4?! Nf6 5.Nc3 e5! 6.dxe5 Qxd1+ 7.Kxd1 Ng4! still leads to 8.Nd5 Nxf2+ 9.Ke1 Nxh1 10.Nxc7+ with Crafty version 19.19 indicating a substantial lead of +0.99 for white. Both kings lose their ability to castle. The one game in Chesslab gives a win for white.

It looks to me like 4.e4 is the better move over 4.Nf3. Does anyone have a different analysis?
