  Phony Benoni: By the way, note the heroic work of the bishop on h7. It's why the White rooks is sitting exposed on a2 rather than being safe on b1.

  agb2002: Black has the bishop pair for both knights.

The knight on c3 protects the rook on a2. Therefore, 27... Rxc3:

A) 28.Qxb3 Rxc1+ followed by Rxb3 (or Rxd1) wins a rook and a knight.

B) 28.Rxc3 Qxd1+ wins decisive material.

C) 28.bxc3 Qxa2 wins a knight.

D) 28.Raa1 Qxd1+ 29.Rxd1 Rxb2 wins a knight and a pawn.

E) 28.Rca1 Qxd1+ wins a knight at least (29.Rxd1 Rc2 30.Rb1 Rxf2 31.Nf5 Bxf5 32.gxf5 Rxf5, etc.).

  al wazir: Easy.

White could have held his losses to a ♘ by playing 28. Rca1 -- a ghastly move.

Feb-06-19  saturn2: I saw 27...Rxc3

28. Qxb3 Rxc1+ (Rxb3 is also enough) 29. Qd1 Rxd1+

28. Rxc3 Qxd1+

28. Raa1 Rxc1 29. Qxc1 Rc6

  patzer2: Solving today's Wednesday puzzle was easy for me. The Rook on a2 is under-protected and guarded by only one piece. Remove the guard with 27...Rxc3 -+ and White is busted.

So where did White go wrong? The clear losing move was 27. Qd1??, allowing 27...Rxc3 -+ (-8.44 @ 33 ply, Stockfish 10). Instead, 27. Rca1 ∓ to -+ (-2.09 @ 30 ply, Stockfish 10) protects the Rook on a2 and gives White practical drawing chances by making the win much more difficult for Black.

Earlier, instead of the tempo wasting 12. Ng5?! h6 13. Nf6 Nh5 ⩱, I like developing with 12. 0-0 =.

Even earlier in the opening, instead of the rarely played 9. a3 =, I prefer the popular move 9. h3 = as in White's win in N Zhukova vs V Gunina, 2013.

Feb-06-19  eblunt: Strange how White decides to give Rook and Knight away, rather than just the Knight. Or was he going to resign anyway if he just lost the Knight ?
Feb-06-19  Carlos0012358: White taking the Black Queen instead of 28.Rca1 was a horrific move.
Feb-06-19  Cheapo by the Dozen: As others have said, really easy for a Wednesday. Just chop the defender and check that White doesn't have any interesting Zwischenzueger or other counterplay.
Premium Chessgames Member
  drollere: what was the point of 27. Qd1, unless trading off the Q's? that seems like the losing move.
Feb-06-19  Bubo bubo: <Removal of the guard> with 27...Rxc3 is so easy for a Wednesday that it is almost difficult again - I wasted some time searching for some hidden snag.
Premium Chessgames Member
  whiteshark: 27...Rxc3 wins a piece, and that's it.
Feb-06-19  saturn2: Why did not black choose 26...Rxc3?
Premium Chessgames Member
  moronovich: <saturn2: Why did not black choose 26...Rxc3?>

Because the white queen covers Ra2.

Feb-06-19  ChessHigherCat: It's kind of cute because white has several options (all of them bad) 27...Rxc3 is the first move you think of because it leaves the R on a2 hanging but then you see it's even better because if 28. Qxb3 Rxc1+ 29.K... Rxb3 with a whole rook up or if 28. Rxb3 then Qxe1+, so white can't win for losin'...
Feb-06-19  ChessHigherCat: <Moro> means 26. Rxc3? 27. bxc3 and the Q covers the R

Bit late, but alas. This is one of those 'remove the defender whilst defending an en prise piece' tactics that are so popular in Puzzle Rush it hardly becomes a no-brainer. After <27....Rxc3> Black takes out the defender of Ra2 simultaneously defending Qb3. I actually sort of stopped here, realizing Black will at least win a piece, but White's peril is even worse as he can't even take with a piece with more losses: 28.Qxb3 Rxc1+ with 29....Rxb3 or 28.Rxc3 Qxd1+ with 29....Qb1. So that leaves <28.bxc3 Qxa2 -+> and Black also has all the activity.
