to remove a defensive piece in such a position.} 29. Ne4 {Brining more pieces

Logical. The Bishop was no defending piece and the knight was to dangerous I
guess.} 30. Bxe4 {Of course black want's to exchange pieces to survive.} Re8 {
If I compare this position with the position 5 moves ago, I would think black
can be happy with this position.} 31. Ne5+ {White's problem piece is the

sides have about 40 minutes on the clock according to the tournament website.
Let's look at the position: Black has a doubled pawn on the a file and the
bishop on f8 looks passive. The d-pawn is a passed pawn. White has 2 passed
pawns (g- and f-pawn) and the bishop pair, but the bishop on c1 looks as
passive as the bishop on f8. Black is a pawn up.} c4 {
I think this is a move to activate the rook via c5.} 37. Rh5 {

the pawn.} d5 45. Bf5 Bd6+ 46. g3 Rd1 47. Bc3 Bc5 48. Ba5 {
now the Nd7 is in danger. Ke8 is expected.} Ke8 49. Bg6+ Kf8 50. Ne3 {
