and then black has a choice between 9...Kg8 or 9...Ke8. i think Ke8 is better
with 9...Kg8 maybe there is 10.Qf3,Qe8 11.e3,Bxe3 12.Nxe3 i don't know what would happen after that. maybe 12...Nb4. ? weird position. it looks like white needs to get some pieces developed. maybe he'd like to play d5.
i'd say this 8.Bxf7+ variation has already been analyzed and is probably not so good for white. any ideas?
♡ 23 ( +1 | -1 ) not so good,crafty gives more than a two pawn advantage to black after KxB. i dont think the sac is sound because white doesnt have enough peices developed to continue through with an effective attack
♡ 51 ( +1 | -1 ) white can win material back pretty easily, i'm sure. either winning the bishop for a pawn by force with mate threats in my first post's example.
and the 9..Ke8 move..... 1.e4,c5 2.c3,Nf6 3.e5,Nd5 4.d4,Nc6 5.Nf3,cxd4 6.cxd4,d6 7.Bc4,Nb6 8.Bxf7+!?,KxB 9.Ng5+,and after 9...Ke8, 10.e6 is probably the best move, and again it looks like white will win back material soon. i'm just wondering whether white can develop well after black's best moves (whatever they are). d5 looks like a very good play if white can get it in.
♡ 61 ( +1 | -1 ) Looks okay for Black. In general, upsetting the king in this way creates light-squared weaknesses around the exposed king, so it's very useful to retain the light-squared bishop. If White want to attempt this general type of thing, he's better off trying for a Nxf7 sac rather than a Bxf7 one so that he has the option of Bc4+ to develop with tempo.
After 1.e4 c5 2.c3 Nf6 3.e5 Nd5 4.d4 Nc6 5.Nf3 cxd4 6.cxd4 d6 7.Bc4 Nb6 8.Bxf7+ Kxf7 9.Ng5+, Black has 9... Kg8 10. Qf3 Qe8 11. e6 Nd8 (11... Bxe6 12. Nxe6 is perfectly fine for White) 12. d5 h6 13. Nh3 Nxd5 14. Qxd5 Bxe6 and while Black's development is awkward, White has nothing to be happy about either.
