  tpstar: Well, little friend, let's go over it together! The opening is the Queen's Gambit, Slav Defense (2 ... c6) which became the "Triangle Defense" after 4 ... e6. (The sharp Anti-Meran Gambit starts with 4 ... dc 5. e4 b5.) Then Black surprised us by taking 6 ... dc!?, then the unique 9. e4 e5! 10. de Ng4 which I have never seen before (in this setting), but it worked great! After 11. Bf4 Qa5 White could have tried 12. Qd4 to hold the Pe5, but then 12 ... Rd8 induces 13. Qxc4 Ngxe5 with an even game (13. h3? Ndxe5! [trapped!] 14. Nd5 Bc5 and Black is rolling). Instead White sacrificed a Pawn with 12. e6!?, opening up Black's Kingside. After 17. Be4 White probably expected 17 ... Rf7, then 18. Bxe5 Qxe5 (18 ... Re7 19. Qh5) 19. Bxh7+! Kxh7 20. Qxf7 wins the exchange. But Black chose 17 ... Nf7!? giving up the exchange differently, which White declined with 18. Rad1. If instead 18. Bxf5 Qxf5 note the Qe8 has no escape squares, so Black might regain the exchange later, although it will take a while (g6/Kg7/Qf6/e5/Nd6), or else 19. Rad1 e5 20. Be3 Qe6 21. Qxe6 Bxe6 with 2 Pawns for the exchange. So that will always be one of those "What ifs" but still Black remained 2 Pawns up. After 21. Bd4 Bc5! chopped wood, as did 23 ... e5 24. fe Rxf2 25. Kxf2 Qd4. The conclusion would be 29. Ke2 Qxd4 30. Qxb7 Qf2+ 32. Kd1 Ne3+ 33. Kc1 Qe1+ 34. Nd1 Qxd1++, so White resigned. Understand now?
May-23-04  Lawrence: <nutsaboutchess> and <tpstar>, a silicon suggestion is that White should have taken the Rook on move 18:

18.♗xf5 ♕xf5
19.♗c7 ♕f3
20.♖ae1 ♘g5
21.h4 ♕f7
22.♕xf7+ ♘xf7 eval +1.03 (Junior 8, 6 min.)

Junior also finds a way for White to wiggle out of mate, 29.♔d2 ♕xd4+ 30.♔c1 ♕g1+ 31.♘d1 but with an eval of -4.53 (15 min. search) Arencibia did The Right Thing.

  plang: This opening is a hybrid Catalan-Semi Slav (the Informant categorized it as E07 which is the Closed Catalan). White played this as a gambit not really attempting to regain the pawn on c4 but his compensation never seems quite sufficient. Topalov has used this system with White a few times most recently in a short draw with Kasparov at Sarajevo 2000. 18 Bxf5 had been played in Mochalov-Yagupov Orel 1999 (game not included in this database); 18 Rad1 was new indicating that White was not comfortable with Black's play on the kingside light squares had he taken the exchange. After 23..e5! Black's counterattack was decisive. 26 Ne2 would have held out longer.
