True - White is up a pawn, but he has to deal with Black's activity especially against his weak light squares. In no way does he want to take on h4 and expose his king.} 27. Ra7 $2 {White decides to first attack the bishop on e7 before retreating for the defense.} (27. Ra5 $1 {was the best idea, chasing that pawn if it decides to advance to h3.} h3 28. Rh5 Rb8 $1 {Threatening Rb1.} 29. Rxh3 $2 (29. Qc1 $1 Qxe4 30. Rxh3 {and White's position of the rook on h3 is awkward, but he should hold the balance.}) 29... Rfc8 $19 {a second and surprising threat! The queen is trapped.}) 27... Bd6 $2 {Returning the favor. The immediate attack would've yielded a victory.} (27... h3 $1 {Black's threat is simple - Qe2 followed by either Qf3 or Rd1. It is also surprisingly unstoppable.} 28. Re1 (28. Rxe7 Qe2 29. e5 Rd1 {is lights out.}) 28... Qe2 $1 { simply not caring about the rook on e1 thanks to the back rank weakness. Black will play Qf3 next move and win.}) 28. gxh4 $6 (28. Ra5 {would still give hopes of neutralizing Black's initiative.}) 28... Bxh2+ $1 29. Kg2 Bb8 30. Ra8 Qe2 31. Rc1 Qg4+ 32. Kf1 Rd3 (32... Rd1+ $1 {was more powerful.} 33. Rxd1 Qxd1+ 34. Kg2 Qg4+ 35. Kf1 Rd8 {and to prevent checkmate White must give an exchange, which gives Black reasonable winning chances even though there is still a long road ahead.}) 33. Qb6 Rfd8 (33... Rdd8 $1 {this seems like a sad necessity, but because of Black's initiative against the naked king it would have given him a strong attack.}) 34. Rxb8 Rd1+ 35. Rxd1 Qxd1+ 36. Kg2 Qg4+ 37. Kf1 Qd1+ 38. Kg2 {Cheparinov escapes by the skin of his teeth and secures a half point.} 1/2-1/2
