Greetings. After 1. e4 c5 2. Nf3 e6 3. d4 cd4 4. Nxd4 Nf6 5. Nc3 Nc6 6. Bg5 h6 7. Bh4 Be7 8. Qd2 Polugajevski in his "Sizilianisch  Morra Gambit bis Scheveninger System", Sportsverlag Berlin 1987, gives 8.Qd2? and recommends Nxe4! Without remembering Polu's recommendation, last night I won an OTB game as Black after 8. Qd2 Nxe4 9. Bxe7 Nxd2 10. Bxd8 Nxd4 ... But looking at it again, surely after 8. Qd2 Nxe4 9. Nxe4 Bxh4 10. Nd6+ White has huge positional compensation for the pawn ? For example 10... Kf8 11. OOO and Black seems very disorganised; surely White has more here than in the Mikenas English ... Or does Black have a better 8th move ? Regards, Peter  Peter Billam, DPIWE/ILS/CIT/Servers, hbt/lnd/l8, 6233 3061
