My name is Geoffrey Haug.

The highlights of my (mediocre) career.

Madman99X: Houdini gives the best defense to 19. Nb4 as 19 ... Ra6 20. Qxd6 Be7 simply conceding the knight to protect the back row.
   Sep-27-18 Y Zherebukh vs Nakamura, 2017 (replies)
Madman99X: Ironically, Houdini 6 gives Qe8+ as white's best move in the ending position. You know you're in trouble when the engine suggests a spite check.

Madman99X: Methinks the knight is overworked. 40. Rexe6 Nxe6 41. Rb7+ Rxb7 42. axb7 etc... looks pretty straightforward. I plugged this into Houdini (after I solved the puzzle for once) and Houdini says 40... Nd7 is a better move at -15.81 on 27 ply depth.

Madman99X: [DIAGRAM] the position after 69. Nxd6 is mate in 22 according to Lomanosov tablebases. (Of course under rapid time controls....)

Madman99X: This puzzle was instructive to me, as I backed up a move, and found 38. Bf8??? which threatens mate, but also single-handedly opens up a line for the B-file rook and hangs the white d8 rook. From this point, anything that defends the mate without losing material wins. The text is ...

Madman99X: Bg5 seems powerful to me, and I think I would have played it on the board, but I confess, I did not see through the end after f6.
   Mar-09-15 L Lalla vs V A Martin, 2005 (replies)
Madman99X: Isn't 2005 a little anachronistic for Bobby Fischer Teaches Chess? I wonder if the individual playing the black pieces duplicated a blunder from yesteryear?

Madman99X: If 29. Nc7 Rxc7 30. Rxe8+ Kf7 31. Qxh7+ Kxe8 32. Qg8+ Qf8 33. Qe6 Kd8 [DIAGRAM] Where is the win? Black is a piece up. It looks like white would have to play to try to force a perpetual.
