Beware of traps along the way

Beware of traps along the way

Therefore each and every time a beginner or a novice or even a master is offered a pawn or a piece on a platter it is important to have a closer look and deeper calculation before capturing.
In the game which follows, White is comfortable but walks into a obvious trap when he is tempted with a pawn offer by Black. He ends up losing a piece and thereafter Black, without taking any risks, simplifies the position by exchanging pieces to coast to a simple win.

 White: Sergey Kudrin (2525) – Black: Larry Mark Christiansen (2610)

The French Defence
 3.Nd2 Be7 4.Bd3 dxe4 5.Nxe4 Nf6 6.Nf3 Nbd7 7.0–0
If 7.Qe2 Nxe4 8.Bxe4 c5 9.Be3
7...Nxe4 8.Bxe4 c5
Black is opting for sharp continuation
9.c3 0–0 10.Qe2
If 10.Bc2 cxd4 (10...Qc7 11.Re1 Rd8 12.Qd3 Nf8 13.Qe4 Bd7 14.Ne5 cxd4 15.Qxd4 Be8) 11.Qxd4 Nc5 12.Qg4 e5 13.Qh5 e4
11.Rd1 cxd4
He doesn’t want to keep tension at the centre and would rather clear it out! If 11...Nf6 12.Bg5 h6
This may look interesting but White could have been better off after 12.Nxd4 Nf6 (12...Nc5 13.Bc2 b6 14.b4 Nb7 15.Qe4 f5 16.Qf3) 13.Bc2 Rd8 14.Bg5
12...Nf6 13.Bg5
Worth a look is 13.Bd3
13...Bd7 14.Rac1 Qb6 15.Ne5
Going for the centre. He can also try out 15.d5
15...Bb5 16.Qf3 Rad8
Now the players have all their pieces positioned into play
He could have tried 17.Qh3 . If 17.Bxb7 Rxd4 18.Be3 (18.Bc6 Rfd8 19.Rxd4 Qxd4) 18...Rxd1+ 19.Rxd1 Qc7 20.Bf4 Qc2
17...Nd5 18.Bxe7 Nxe7 19.Bxb7

White has simply not given much thought to the position and walks blindfold into a very obvious trap!
A good move which takes the game into Black’s territory. Black avoids the pitfall 19...Rxd4 20.Ne3  which balances the position
20.Be4 f5
White is now forced to part with a piece
21.Bc2 fxg4 22.Qxg4 Qd6 23.Re1 Bd7
After winning the piece. Black has to just defend the attacked pieces. If 23...Nf5?! 24.d5! Bd7 25.dxe6 Bxe6 26.Rcd1 Qb6 gives advantage to Black
 24.Qe4 Ng6 25.Bb3 Kh8
Getting out of the dangerous diagonal and dashing all White’s hopes of some sort of a counter-attack
 26.g3 a5 27.Re2 Rb4 28.Bc4 a4 29.b3 Rb6 30.Rce1
Tripling forces on the crucial central file but it does not gain him anything
30. ..Rf6 31.Qa8+ Rb8 32.Qa7 Rc8 33.Bd3 axb3 34.axb3 Ne7 35.Be4 h6
Black is slowly and systematically improving his position which would lead him to victory
36.Rd1 Nd5 37.Rc2 Nc3 38.Re1 Nxe4
Black should be more than happy with the exchange of pieces
39.Rxc8+ Bxc8 40.Rxe4 Qc6 41.d5 exd5 42.Re7  and even though the queen and rook have invaded the seventh rank he resigned as Black can wrap up the game with 42. ..Qc1+  43.Kg2 Ba6  44.Qa8+ Kh7  and Black has to either part with heavy material or face checkmate.
