| Feb-25-21 | | phantasmagorium: Whay not 20... Be7? I cannot see anything especially devastating after 21. Bd6 0-0. Or 21. Qxg7 Rf8 22. Bd6 Bxb5. |

| Feb-25-21 | | Walter Glattke: 3 tempi for black ... Looks like an exhibition match ... Findung at the first website in Blitz a piece win by 18.Rxe6+ Bxe6 19.Bb5+ Bd7 20. Re1+ Be7 21.Bd6 0-0 22.Bxe7 Qe8 23.Bxf8? (Qxf8? Bxd7) now 23.-Qxe1#, hence 23.Bxd7 Qxd7 24.Bxf8 Rxf8 25. Qxh5 Little white advantage then so Schwitz (sweat) instead of Blitz (Flash, quick chess) they played 20.-Qe7 (21. Rxe7+Bxe7 22.Qxg7 Rf8) 21.Bxd7+ Kxd7 22.Qb5+ Kc8 23.Qf5+ Qe6 24.Rxe6 fxe6 25.Qxe6+ Kd8 26.Qd5+ Ke8 27.Bg5 threatens Qe6+ 27.-Ba3 28.Qxb7 28.-Rd8 29.Bxd8 0-0 (29.-Kxd8 30.Qb8+ Kd7 31.Qxh8) decisive material, QPP for R, it need a scheitz/ sweat to find this, looks a bit like a "lucky punch" (23.-Kd8!? 24.Rd1+!/23.-Qd7? 24.Re8#) |

 | | agb2002: White is one pawn down.
Black threatens Qxg5.
The first move that comes to mind is 18.Rxe6+:
A) 18... fxe6 19.Bg6#.
B) 18... Bxe6 19.Bb5+ Bd7 20.Re1+ Be7 21.Bd6
B.1) 21... Bxb5 22.Rxe7+ Kf8 (22... Qxe7 23.Qxe7#) 23.Rd7+ Kg8 (23... Ke8 24.Rxd8+ Rxd8 25.Qxe7#) 24.Rxd8+ Rxd8 (24... Kh7 25.Qxh5#) 25.Qxd8+ wins decisive material. B.2) 21... f6 22.Qg6+ Kf8 23.Rxf6+ gxf6 (23... Kg8 24.Bc4+ Be6 25.Bxe6#) 24.Qxf6+ Ke8 (24... Kg8 25.Qg6+ as in this line) 25.Qg6+ Kf8 26.Bc4 Qe8 27.Qf6+ Qf7 28.Qxf7#. |

| Feb-25-21 | | Brenin: A couple of hours later than usual, with CG not responding to provide my usual breakfast accompaniment, I find an excellent new (!) POTD. The first three moves 18 Rxe6+ Bxe6 19 Bb5+ Bd7 20 Re1+ are hard to resist, and then one has to check that neither 20 ... Be7 21 Qxg7 nor 20 ... Qe7 21 Bxd7+ (as played) leads to safety for Black. Thank you CG! |

| | agb2002: I made a mess in my line B.2: 22.Qxg7 and mate soon. Also, I forgot B.3) 21... O-O 22.Bxe7 Qb6 (22... Qc7 23.Bf6 and mate soon) 23.Bxd7 with a winning position. |

| Feb-25-21 | | saturn2: I took 18 Rxe6+ Bxe6 (fxe6 and Le7 wirse)19. Bb5+ (remove the attacked Bd3 with check)Bd7 20. Re1+ Be7 21. Bd6 21...Bxb5 22. Rxe7 or
21...Kf8 22.Bxe7 lose queen |
|
| Feb-25-21 | | TheaN: <18.Rxe6 Bxe6 (fxg6 19.Bg6#)> and 18....Be7 is a worse version of the main line. <19.Bb5+ Bd7 20.Re1+>. Here I kind of discarded Qe7 as being lost for Black. Of course, White has invested a rook so it'd be Q:2R, but in these positions where White can force the king to move, the rooks are rather helpless. Instead, <20....Be7 21.Qxg7> and White creates just enough time to get in a similar situation. <21....Rf8> Bxb5 immediately opens up the d-file, as after 22.Qxh8+ Kd7 23.Rd1+ +-. 22.Bh6 and 22.Bd6 are similar, but after the former 22....Bxb5 23.Qxf8+ Kd7 24.Qxf7, White keeps quite a bit of material on the board. <22.Bd6 Bxb5 23.Rxe7+ Qxe7 24.Bxe7 Kxe7 25.Qe5+ Kd8 26.Qxb5 +-> and White simplifies to the following end game.

Uncoordinated rooks and very loose pawns, so this is a rather straightforward win for White. |

| Feb-25-21 | | King.Arthur.Brazil: The first moves seems direct: 18. ♖xe6+ ♗xe6 (Since 18...fxe6 19. Bg6#). Then 19. ♗b5+ ♗d7. (Or else, lose the ♕ with {Qd7). Also, the column is used to attack: 20. ♖e1+ ♗e7. I guess this is clear for everyone. Now, what? Then, one (as me) could take a wrong way, thinking about 21. ♗c7 ♕xc7 22. ♕xe7# or 21...♗xb5 22. ♗xd8 ♔xd8 23. ♖xe7 ♔c8 24. ♕e5 with checkmate next. However, this jewelry vanishes by 21...O-O. Then, White cannot recover the material, as A) 22. ♗xd8 ♗xg5 after choosing the ♗: 23. ♗xg5 ♗xb5 or 23. ♗xd7 ♗xd8 White lost a ♖; B) 22. ♖xe7 ♕xe7 23. ♕xe7 ♗xb5 and Black has 2♖ by ♕. Note that: 23... ♖fe8 is not so good because of 24.♕c5 ♗xb5 25.h3 ♖e1+ 26. ♔h2 ♗c6... and Black has a counter-attack. Bad is 24...♖e1+ 25. ♗f1 a6 26. f3 ♗b5 27. c4 ♖c1 28. ♔f2 ... when White escapes. If 22. ♕xe7? ♕xe7 23. ♖xe7 ♗xb5 with a ♖ advantage. Therefore, the continuation must be 21. ♗d6. Following, {21...Bxb5 22. Rxe7+ (If 22...♕xe7? 23. ♕xe7#), 22...♔f8 23. ♖d7+ (Also 23...♔e8? 24. ♖xd8+ ♖xd8 25. ♕e7#). 23...♔g8 24. ♖xd8+ ♖xd8 25. ♕xd8+ ♔h7 26. ♕g5 and White has a ♕ by a ♖ and keep on attacking next with possible 26... ♗c6 27. ♕xh5+ ♔g8 28. ♕g4 ++. Time to check out. |

| Feb-25-21 | | Refused: 18.Rxe6 has to work.
18...Bxe6 19.Bb5+ Bd7 20.Re1+
a.)20...Be7 21.Bd6+-
b.)20...Qe7 21.Bxd7+ Kxd7 22.Qb5 looks horrible. |
|
| Feb-25-21 | | Brenin: After 18 Rxe6+ Bxe6 19 Bb5+ Bd7 20 Re1+ Be7, White's choice is between 21 Qxg7 and 21 Bd6. The former, after 21 ... Rf8 22 Bd6 Bxb5 23 Rxe7+ Qxe7 24 Bxe7 Kxe7 25 Qe5+ Kd8 gives the position shown above by <TheaN>, with White having a clear win, but still some work to do. The latter, after 21 ... 0-0 22 Bxe7 Re8 23 Bxd8 Rxe1+ 24 Bf1 Bb5 25 Qxb5 Rxd8 26 Qxb7 Rdd1, allows Black to regain material (Q+B for 2R) on f1, and go into a K and P endgame a P down, White having a passed c-pawn, so a probable (and quieter) win for White. |
