Thanks for those annotations Ragwort, I found them very enjoyable.
Can't say I understand why anyone would decline such a absurd gambit though! If
you go in for the Evans in the first place, why shy away at the first opportunity?
Also in the second game, white gives away his light-squared bishop for no good
reason. Typically it's the most dangerous piece in the Evans, to give it away
without any compensation is really poor play. In fact, the method Lasker used to
defeat the Evans back in the 20s was the threat to remove said bishop with a
knight fork:
[Event "?"] [Site "?"] [Date "????.??.??"] [Round "?"] [White "New game"] [Black "?"] [Result "*"] [PlyCount "14"] 1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5 4. b4 Bxb4 5. c3 Ba5 6. O-O d6 7. d4 Bb6 {So if 8.Qb3 the fork Na5 is possible, although not immediately b/c of Bxf7. Lasker won many games with this.} *
