| sarayu: Not sure I understand 19.Ne4. What did that accomplish for white? To prevent Qxg7? But if Rxe4, it doesn't really put it off. ?? |
|

| clocked: Ne4 is a clearance sacrifice. That is, it clears the path for the rook to come to g3. Also at e4 (as opposed to a4) the knight prevents both QxB and Bd2 and makes the obvious threat of Nf6.
If Rxe4 20.Rg3 gives white at least the draw 20.Rg3 Bc5+ 21.Kh1 Qxg3 22.hxg3 Rxe2 23.Qf6 |

| patzer2: With 26. Rxf7!, Mahia finds the strongest move to finish off his combination, which started with 24. Bg6! Note that if 26...NxRg6, then 27. Rf8+ Nxf8 28. gxf8=Q# wins. |

| Tigran Petrosian: Hold Up! In the chessmaster game database, they play the game up to mate. something is wrong. |

| Tigran Petrosian: 17.Bc5 seems to refute the "attack". |

| patzer2: <sarayu> Your suggested 19...Rxe4 appears to be a win for black. Chesslab.com gives best play after 19...Rxe4 as follows: (4.84 plus score for black) 20. Rh3 Bc5+ 21. Kh1 Qxg7 22. Rg3 Qxg3 23. hxg3 Nd7 24. Qg5+ Kf8 25. Bg4 (Note: black holds on and wins after 25...Re5) (4.93 plus score for black) 20. Bh5 Bc5+ 21. Kh1 Qf5 22. Rbf3 Be3 23. Bxf7+ Qxf7 24. Qxe3 Qf5 25. Rxf5 Rxe3 |

| patzer2: <clocked> Although the analysis is complex, looks to me like 19. Ne4 loses to 19...Rxe4.
After 19...Rxe4, I don't see a draw for white after 20. Rg3. Chesslab.com gives the following favorable continuations for black after 19...Rxe4 and 20. Rg3: (2.96 plus score) 20. ... Bc5+ 21. Kh1 Qxg3 22. hxg3 f5 23. Bh5 Bd4 24. Bg6 Bxg7 25. Qxh7+ Kf8 26. Kg1 (3.73 plus score) 20. ... Bc5+ 21. Kh1 Qxg3 22. hxg3 Rxe2 23. Qf6 Rf2 24. Rxf2 Bxf2 25. Qxf2 (doesn't appear to be a forced draw here for white) (3.90 plus score) 20. ... Bc5+ 21. Kh1 Qxg3 22. hxg3 Nc6 23. Bh5 Nd8 24. Rd1 (6.55 plus score) 20. ... Bc5+ 21. Kh1 Qxg3 22. hxg3 Rxe2 23. Qh5 Rxc2 24. Rxf7 (7.12 plus score) 20. ... Bc5+ 21. Kh1 Qxg3 22. hxg3 Rxe2 23. Rd1 |

| clocked: The Chesslab analysis is meaningless...the computer is not looking deep enough to see the correct evaluations. Try making the suggested moves and recheck. Line 1) 24.Bg6? nope 24.Qg5! wins
Line 2) 25.Qd8+ Kxg7 Qg5+ etc is a forced draw
Line 3) 24.Rd1? 24.Bg6 is mate in 4
Line 4) and 5) don't play 23.Qf6 |

| patzer2: <clocked> Your analysis is indeed much better than the online computer's. Thanks for the huge improvements on the Chesslab analysis. line 1) After 24. Qg5! Bxg7 25. Qd8+ Bf8 26. Qxc8, black does indeed appear to be busted! Line 2) Forced draw is now clear, and white may even have winning chances with 26. QxBc8 in this line. Line 3) 24. Bg6! Rh4 25. gxh4 fxBg6 26. Rf8+ Bxf8 27. gxf8(Q)# is indeed mate in four. Lines 4 and 5 don't apply as you recommended 23. Qf6! instead of 23. Qh5 or 23. Rd1. Indeed, Crafty was also clueless in overlooking the strength of 23. Qf6! in analyzing 19...Rxe4. Looks like I'll need to find another program to assist with analysis, and question computer assessments much more closely in the future. Just curious. Do you recommend or use any computer programs for analysis? |

| FSR: Oddly, I was just looking this morning at a copy of this game that I had printed out long ago. I have the note "17...Bc5! Evans" (i.e. GM Larry Evans) on it, consistent with Tigran Petrosian's assessment. |

| SirChrislov: It looks like Tigran Petrosian and I have the same Chessmaster game database. GM Miguel A Quinteros from Argentina, was once an aide to none other than Bobby Fischer! |

| SirChrislov: <WhiteRook48: What was 8... Qxb2 for?> This move Sir, is the playable poisoned pawn variation of the Sicilian Defence. Wht could have played the rather tame 8.Nb3. 15... Nxf6 is an improvement over 15... gxf6 16.Qh6!
17... Rxd4
<Instead 17... Bc5 "seems" to refute the attack.> 18... Qe5
<If 18... Bxc3 19.Rxf7! Kxf7 20.Qxh7 looks strong.> 23... Nc6
<loses beautifully. so does 23... f5 24. Qxh7+ Kxh7 g8=Q+.> |
|

|
| SirChrislov: 24... Qxg6
<If 24... fxg6 25.Rf5#; or 24... hxg6 25.Qh8#.>In the Chessmaster games collection, this game continues to the end:
28... Ke8 29.Rxg8#. |

| WhiteRook48: 15 Bf6!! |
|

|
| SirChrislov: The foulty 15... gxf6? has serious consequences when followed with the correct 16.Qh6! as in:
R Byrne vs Larry Evans, 1965
note how correct is the clearace sac 18.Ne4!(in this above game is 19.Ne4!) for the rook to come to g3 with +. |
