13.g5 or 13.h3.} 13. Nf5 $3 $146 {A stunning novelty. It would be hard for
Black to meet in any case, but in a rapid game it is devastating.} gxf5 14.
gxf5 {So far White has just a pawn for the piece, but the open g-file is a
huge threat to the black king, while d6 and h5 are both weak. I doubt many
Black players will want to defend this position, so they will be looking for
deviations at move 12 or earlier.} Nbd7 ({Eight days later a second game was
played in this line. My guess is that Black was surprised. The game continued:

{The following game is interesting for a few reasons. Firstly, White had the
chance to play an untested suggestion of Mihail Marin (GM Repertoire 4, page
297) but either chose not to or was unaware of it. Later the game had many

born-again knight continues to plague me.} Rh6 {Still losing, but the only

41.Nxe5. In general, when trying to draw an ending a pawn down, choose a rook
ending not a knight ending.}) 40. Rxg5 Rxh4 41. Rg2 $2 {White had seized his
chance superbly but now he makes one passive move in the rook ending and the
win is gone.} (41. Rc5 $1 Rxh2 (41... Rh6 {also looks dreadful. For example:}
42. h4 Ke7 43. h5) 42. Rxc6 Rh5 43. Re6 Kf7 44. Re2 {I think this is probably
winning. A pawn down with the king cut off, I would have been in search of a
miracle save.}) ({Or} 41. Rg6 $1 {would probably transpose to 41.Rc5 after
taking on h2 as instead} Rc4 {gives White a few strong options, including} 42.

make a move" but I made an exception in this case.     Summary: During moves
1-30 and 34-50 I played reasonably well. Moves 31-33 were freakishly awful.}
