Thanks for your anaylsis guys. It was very instructuive. If I could summarise, it seems to me that Black has big chances for the upper hand after 14.Ne3, but 14.Qe2 promises equality, at least after 15...Qd6! The only line that may give white equality after 14.Ne3 and the whole 15.Ke2 is Mike's 18. Nc4 move (if black insists on 15 ...f5). But it seems that black bursts through with a strong attack if he goes in for the knight exchange (18 ...Nxd4!). Either that or Claus-Juergen's idea of 15 ...Nf6 seems to give black a simper way to keep even a slight advantage, but 15...f5 is more ambitious. 11...Qxd5

Mike Ogush: "Black doesn't have enough compensation for the piece".
But, whites weak-points: f2 pawn; King position; Pin on c4-knight; Undeveloped a1-rook. Whereas Black's strong points are noticable: strong dark squared bishop; dominateing knight; Active d-file rook, and easily-made-active h to e file rook; relatively safe king; active queen cooperating with the rest of the army.
Concretely, 21 ...Bxf2! leads to a big black advantage 21...Bxf2
This is very messy stuff that follows, and I can only suggest that black has the better of it becasue of the previous mentioned advatages and disadvantages - and because Junior 8 has a rating of some 2 pawn advantage for black. 22.a4
