Nb5, Black should have responded 10 ... Na6, White won exchange and later won another piece from Desperado tactics, then mate on back rank for 1-0. M) Stonewall Attack, good development, 8 ...

P) Ruy Lopez Steinitz, 4. d4 over 4. 0-0, good position out of opening, opposite side castling, White gave up QP for RR but wide open lines on the Kingside, chances to maneuver Rooks and check on back rank, Black could have won exchange with correct Discovered Check (45 ... Ng4+ over 45 ... Nxe4+), eventually Black prevailed in RRPP vs QPPP endgame. M) Center Counter with 2. ed c6!? 3. dc e5!? 4. cb Bxb7 so 2 Pawn gambit, try 5. Bb5+ to trade down, Black dropped exchange (11 ... Re8? 12. Bxe8 Qxe8), White castled into safety but should have played 19.

| | tpstar: P) Giuoco Piano by transposition, 4. d3 Nge7 (4 ... Nf6), White lost a piece from fork on d4, Desperado on g7, good play to exchange Queens and trade down, keep King centralized instead of retreating, missed Knight fork winning Rc1, eventually Black won R vs RN endgame but missed cute trick to trade Rooks:
click for larger view35 ... Rxa3! 36. Rxa3 Nc2+ & 37 ... Nxa3 with a quick win, instead 35 ... Nf5+ and it took 20 moves longer. M) Bad opening as Black (1. c4 Nf6 2. d4 d5!?), the game went 3. c5!? Nc6, good development and traded Bad Bf5 for Good Bd3, won Pa3, won exchange on d2, but White had advanced Queenside Pawns which eventually won (1-0). 1. Use your time
2. Avoid mistakes
3. Good manners |

| | tpstar: P) Evans Gambit by transposition, 6 ... dc!? riskier than 6 ... Nge7 & 7 ... 0-0, Black tried 8 ... Qc6 intending 9 ... c2 fork, still up 2 Pawns until 14. Qa3 d5?! (14 ... b6 & 15 ... Bb7), discussed keeping lines closed when up material, eventually lost Queen for R leading to QN vs RR, Black declined draw offer, White used Q+N well and mated for 1-0. M) English with 1 ... e5 2. Nc3 Nf6, good opening, lost piece for 2 Pawns after 6. a3 Ba5?! (6 ... Bxc3) 7. b4 Bxb4 8. axb4 Nxb4, decent game but White traded down and forked Na5 & Rf8 for 1-0. P) Sicilian Sozin, great opening, gained space with 15. e5 Ng8 16. Ne4 Bb8 for  , won Pb7 but Black doubled f Pawns, 28. Bd5 nice Interference move (if 28 ... exd5 29. Qxf5) but then 28 ... Qb8 29. f4?? Rd8 won a piece and 0-1. M) Philidor, 6. Bc4 over 6. Bb5+ Bd7 7. Bxd7+ Qxd7, wasted time with 10. Ndb5!? a6 11. Nd4, won Queen nicely after 15. Qg4: 
click for larger view15 ... Bxc3 16. Nh6+ (16. bxc3 is even better winning Q for N next) Kh8 17. Qxd7 Bd4+ (Zwischenzug) 18. Kh1 gxh6, lost exchange from Knight fork on d2, stood better but White fell into back rank mate for 0-1. P) Giuoco Piano Main Line to 9. bxc3 Bxc3?!, White played 10. Ba3 and should have won quickly after 10 ... d6 11. Qb3 Bxa1 Sascha Schiffers vs Mi Reinert, 1999 & compare Greco vs NN, 1620 with 10. Qb3 instead (White 5-0 in db), Black defended well and was up 2 Pawns for 0-1. M) Petrov as Black, Cochrane Gambit, 5. d4 Nxe4?! 6. Qh5+ g6 7. Qd5+, Lazarev vs Kundichev, 1982 , best is 5 ... c5 Short vs Shirov, 2002 , Black had OK game until lost exchange (20. Bh6+), endgame was easy win for White. P) Max Lange/Scotch Gambit, 5. 0-0 Nge7 6. Re1 0-0 and Black already fine, Pawn up until Queen trade, then Black won another Pawn, stood better in RRBB vs RRNN but lost on time. |
