14...Nxc2 "Black seems to be in a solid position, if offered material, why not take it?"
Well, (1) because when you have a winning advantage it's safest to simplify into a winning endgame and (2) Black's position is not solid at all.
So 14...Qf5 offering to trade queens and now:
15.Qxf5 Bxf5 16.Rxe5 g6 and Black's position is solid, up a piece for a pawn.
15.Qg3 Nc6 and Black's position is solidifying, up a piece.
15.Rxe5 is very sharp. With one move, White threatens Qf7#, Re8#, and Rxf5. I'm sure this would scalp some players. At blitz time controls it would probably scalp me! But if Black calmly proceeds with his original plan of trading queens, 16...Qxg3! the position is defused. White really must take back to have any chances, so 17.Nxf3 and now 17...Bg4 offering another trade and Black looks a little better.
I think White can put up a strong fight still due to being able to keep Black's rook trapped at h8 for a good portion of the ensuing game.
Agreed. I actually like your sacrifice... it was imaginative and somewhat sound.
I've played this game recently on chess.com "little chess partner" with the ply setting at 12, which--if I am not mistaken--means the engine will look as deeply as 12 moves ahead if it sees it fit. It takes about 1-2 minutes for the engine to look that deeply.
My play style usually involves imaginative attacks--at least I like to think so. By imaginative attacks I do not mean fictional, but rather awkward and unorthodox, with some substance to them.
I'd like it if someone could point out some lines of defense for black in this game. I played white this game.
