Missed Tactics

 An instructive game I played recently showing tactics I missed, as uncovered by an engine analysis.

1 d4 d5 2 e4 de 3 Nc3 Nf6 4 f3 e3  This move is payed only 4% of the time.  My response has not been seen at all, but I like the idea of securing e5 or g5 for a knight.

5 Bxe3 e6 6 f4 Bb4 7 Nf3 Nbd7 8 Bd3 BxN 9 bc Nd5 10 Bd2 f5?  This move, weakening the P/e6, boosts my advantage by a full point, to 1.62.  The bot likes 9 0-0.

11 0-0 0-0 12 Qe2 Qf6 13 Ng5 N7b6 14 Rae1 Re8?  Black fails to appreciate the weakness of having an unguarded Rook on e8.  Unfortunately, by my response I also fail to appreciate this weakness.  I should have played 13 Nxh7.

15 c4? h6? 16 cd hg 17 fg Qxd4+ 18 Be3 Qxd5? 19 g6?  I miss 19 Qh5, dropping my advantage from 8 points own to less than 5.

19...Kf8 20 Bg5 Nd7 21 Qh5 (missing 21 Rxf5+, winning) Nf6 22 Qh8+? (BxN) Ng8 23 Rf3? (Bxf5) Bd7 24 Rfe3 e5 25 Qh4? (Be4!) Bc6? (e4) 26 Rg3? (Be4!) e4 27 Bf1 Re6 28 Bf4  After numerous blunders and second-best moves, I am now at a slight disadvantage according to the bot!

28...Rd8 (Be8) 29 Bxc7 (Bc4!) Rd7 30 Bf4 Bb5 31 BxB QxB 32 Rb3 Qd5 33 Qf2 Rc7?? 34 c4?? Rxc4 35 Qd2 Qc6 36 Qd8+ 1-0  And here he runs out of time, while I have less than a second left!
