Mike69 approached me to play a game, I was happy to oblige, with some comments. Moonbus played White, Mike Black.
1. e4 e5 2. Ng1f3 Nb8c6 3. Bf1c4 Bf8e7
This is a little passive, but still playable. More common would be either ... Nf6 or ... Bc5.
4. O-O
White can also play d4 here and try to seize the initiative.
4... d6 5. d4 Bc8g4
This is not the best. Black should play ... exd4 here, to prevent White from dominating the center.
6. d5 Nc6d4 7. c3 Nd4xf3 8. gxf3 Bg4h3
Not the best move here. The B should retreat to d7.
9. Bc4b5 c6
? Black is going to lose material now, and seriously. ... Bd7 was the move; or even ... Kf8.
10. dxc6 Bh3xf1 11. c7 Bf1xb5 12. cxd8=Q Ra8xd8
The dust settles and we take stock. Black has lost his Q, in return for a R and a B. Materially, not terrible, actually just one P down. Now let's analyze the positional factors: White has an advantage in space with the protected Pe4 hitting on the squares d5 and f5; a dk. sq. B which has potentially good diagonals because the e- and f-pawns are on lt.sq.; a half open g-file on which to place a R and potentially attack the Black K-side; no obvious difficulty developing the remaining pieces. Black's positional factors: an awkwardly placed dk.sq. B, hemmed in by Black's own center pawns on dk.sq.; a weak and backwards QP; the K is not yet in a safe place. Strategical concerns for the immediate continuation: White will aim to box in Black's pieces as much as possible and to activate his remaining pieces as quickly as possible. Analogous strategy for Black. Based on these positional factors, White stands better than merely 1 P +. Stockfish rates White's advantage at +2.87 points (nearly three Ps).
13. c4
This drives Black's lt.sq. B back, further immobilizes Black's already weak Pd6, and prepares to open more dk. diagonals for White's dk.sq.B.
13... Bb5d7 14. Nb1c3 Ng8f6 15. b3
Stockfish preferred Be3 here, but I wanted to open the possibility of attacking the Pd6 with Ba3.
15... Nf6h5
Perhaps played with the intention of posting the N on f4, after suitable preparations. However, ... 0-0 was better here, in defiance of the half-open g-file.
16. Nc3d5
White seizes the vacant d5 sq., which the Black N no longer controls. White has no intention of exchanging his good N for the weak dk.sq. B on e7; rather, the N now threatens a check on c7, which would prevent Black castling. Stockfish now rates the position 3.21+ for White.
