Oct-15-24  King.Arthur.Brazil: The king believes that it is best to protect the ♙ e6 first, with 37. Re1 a5 (for example), 38. Nh3 Kg7 39. Ng5 Rc8 40. Nf7 (40... Rc8 or similar 41. Qh6+ Kg8 42. Qh8#) 40... Rxf7 41. exf7 (Qxf7 42. Re7 wins the ♕. ) Qf8 42. Re7 (threatening Qe5+) Qf8 42. Re7 Rd6 43. Qe5+ Rf6 44. Re6 Qxf7 45. Rxc6... B position is devastated.

  al wazir: 37. Rxf5 looks pretty strong too.

The continuation might be 37...Ke8 (37...Rxf5 38. Nxf6+) 38. Rxf6 Qxf6 39. Nxd5 Qh8 (best is probably 39...Qxf1+ 40. Kxf1 Rxd5) 40. Nc7+ Ke7 41. Rf7+ Kd8 42. e7+.

There's no safe place for the black ♕ to hide.

  Teyss: Hi al wazir,

If 37.Rxf5, then simply ...gxf5 (not ...Rxf5?) and Black wins. Yes the e6 Pawn is annoying but Black can sac the exchange with ...R(any)xe6 Nxe6 Rxe6 to remain a Bishop up.

In the game line, Black has no choice than to accept the Knight sac and after forced moves White will take one of the two Rooks. Then the e6 Pawn is a major asset.

Of course. How could I have missed that?

Thanks.
