  An Englishman: Good Evening: Just because I can see the moves doesn't mean I can understand them...starting with 17.Kd1.

  Troller: <starting with 17.Kd1.>

This move was initially praised by commentators for originality but as they soon realized, Black simply gets a huge advantage by playing what follows in the game. Idea was supposedly to prepare manual castling while keeping the rook guarding the a-pawn for as long as possible. Tactically, it doesn't work though. Better was <17.h6> and the engine evens claims that the absurd-looking <17.Kf1?!> is equal.

After 19..Qg4 White must surrender a pawn, best so with 20.Kc2 getting the king into safety. 20.Qd3 leads to a lost position where White never gets into the game. According to the engine, it is -3 already and quickly goes to -5, never to let up.

Feb-08-22  Ulhumbrus: The move 15 h5 suggests that White wants everything with a centre that is not closed and that seems questionable at least. The question is how Black can best take advantage of it. If after 16...Qd7 Black cannot manage to play tha pawn advance ...d5 one alternative is 16...Qf7 instead.

Much of the problem arises from 10.Nxb6, after which the A pawn becomes a target. Especially after the whole c3 b4 b5 thing. Strategically I see the problem with Nxb6 as creating a qside weakness that can be targeted along with a kside one (the principle of multiple weaknesses) that could be the ruin of the game. Now..

There were 3 obvious candidate moves.. Bb3, Nxb6, and Nxe7+ (followed by Bb3, playing for the two bishops). I personally discard Nxb6 for stated reasons, and think the c3 b4 b5 idea is stronger with the black A file closed. so my choice is between Nxe7 and Bb3. In a rapid game I'd take the B on e7 then play Bb3. In a classic game, and since ultimately black can challenge the LSB with ..Be6, I might go with Bb3 and try to anchor the knight on d5. Not sure, would have to give it more than a 5 min think. But if i was going to play this opening as white, I would have done the home prep and figured that out beforehand. I think the engines would rate Bb3 higher than Nxe7+ since after Nxe7+ Qx Bb3 blacks development is improved, and he is able to regroup his minors to the K side.

anyway.. It's pretty apparent white played too loose and risky maybe seeking to take advantage of complications, but it didn't work.

  HeMateMe: Seemed odd to start an attack with h4 when the center was not fixed and white not castled. Black easily took over the game then.

  scormus: W's position is seriously compromised. The comment by <He MateMe> is spot on. B had castled and later reinforced the BK's safety with ... Kh8, while the WK is left vulnerable.

The first four moves were natural to play and easy enough to find, but I wasn't sure what to choose for move 31 ... I went for ... Nd3+ immediately, which SF rate as only slightly weaker and with a similar follow up to the text.

Apr-19-25  mel gibson: I didn't see that - I should have looked for longer.

Apr-19-25  vajeer: Found 27...Rxf5 28. exf5 Qxf5
After that I thought about 29. Kd1 as a possible defense. After 29...Nxf2+ 30. Kc1 Nd3+ 31. Kd1

Black has three pawns and knight for a rook and strong position.

Apr-19-25  King.Arthur.Brazil: First, I tried the "easy" 27...h6 but after 28. Rgf1 Bg5 29. f4 exf4 30. gxf4 Bxf4 31. Rxf4 Nxf4 32. Qxf4, W has changed the position in his favor.

So, the king went on a predictable sacrifice: 27...Rxf5 28. exf5 Qxf5. Now, with 29. g4 Nb4+ ( 30. Kc1 Qc2# or 30. Kb2 Qc2+ 31. Ka3 Qb3#) 30. Kd1 Qc2+. Now, there are two ways:

a) 31. Ke2 Qd3+ 32. Kd1 Nc2 33. Qxd3 cxd3 34. Ra2 d5, B seems good, b) 31. Ke1 Nd3+ 32. Ke2 Nf4+ 33. Kf3 Rxa4 34. Rgc1 Qb3 35. Rcb1 Rxa1 36. Rxb3 cxb3... also 33 Ke1 (or Kf3) Bg5 and the threats continues.Too many choices to analyze.

If W chose to remove the discovered check, with 29. Kd1 Nxf2+ 30. Ke2 Ng4 31. Qxb6 Qd3+ 32. Ke1 Nh2... or 32... Rf8, B still has the initiative.
