  Jimfromprovidence: I kind of like 21 Qb5 as a defense.

It concedes the rook but protects the white bishop. It does not look like an easy win for black at this point.

  Jimfromprovidence: Here is a great example of an all-out attacking game.

Nunn vs I A Nataf, 1999

Dec-04-16  YouRang: Brilliant, but I didn't see it.

The main idea I tried out was 18...Ng3 19.hxg3 Bxg3+ followed by ...Qxd4+ and ...Rc8+.

It looks like a king hunt, but in reality the king is leading me into an ambush. :-(

Dec-04-16  blackdranzer: I thought about Ng4 for so seems like a good move.

Bh2 was missed completely..becoz I thought Bh2 Qb4 Nd5 and then what?

Dec-04-16  psmith: <JimfromProvidence> Stockfish thinks Black is up by about a full piece after 21. Qb5 Qg1+ 22. Bf1 Qxh1. White just doesn't have any good moves and his King is still exposed.

DR4 64 bit chooses that too if given 6 seconds to find a move, but if given a lot longer it chooses the move below.

21 Be2-d3 gives a score of -3.70 for white depth 18.

  steinitzfan: Beautiful game. The attack seems to be very well executed although I haven't threaded through all the variations with an engine. I guess it says good things about Shogi that someone can play Chess this well and still maintain an interest in both. I'll have to give it (Shogi) a try sometime.
Dec-04-16  5hrsolver: Totally missed it. Can't wait for Monday puzzle.

Dec-04-16  sfm: Incredibly brilliant.
Dec-04-16  5hrsolver: <Jim ----I kind of like 21 Qb5 as a defense. >

21...Rd8 seems to be winning.

Dec-04-16  sfm: There's something excessively brutal about 29.Kb1,c2+ 30.Kb2,c1Q++# so we must hope that Mr. Habu would have chosen 30.-,c1R+# instead.
Dec-04-16  stst: Quite a nice flow, if one can get the Q going. Now it's blocked by its N@f6. So set it to attack (probably a sac, if White chose to remove it first):


White has two choices, fxgN or fxeN

fxeN actually gave Black more resistance, tackle it first (but either way, Qh4+ is the response, later development differed):

19.fxeN Qh4+
20.Kd2 (if Kd1, gN to f2+ forks the R, White loses R... rest should be easy;) Rc8 sets a boundary, or shuts the door for the K to escape to the left.) 21.g3 strongest, drives the Q an disallow Bf4 , but Black got one more sq. for its Q -- Qg5+ 22.Ke1 (again Kd1 allows N fork, R lost) Rxc1+!! R-sac 23.RxR QxR+
24.Bd1 Qe3+
25.Kf1 Qf2#

The other choice:
19.fxgN Qh4+ (same)
20.g3 (again Kd1 allows N fork, R lost) or even worse, Kf1 is mated at once Qf2#, Bxg3+ 21.Kf1 Qh3+
22.Kg1 Bf2#


Dec-04-16  Steve.Patzer: What happened to chrisowen?
Dec-04-16  YouRang: <Jimfromprovidence: I kind of like 21 Qb5 as a defense. >

Yeah, playing against a human (i.e. with higher chance of oversight) <21.Qb5> may be best.

White is crushed if black finds the best move, 21...Kh8!, but if black continues with the original threat: <21...Qg1+ 22.Ke2>

click for larger view

It is tougher and black must still find <23...Qf2+>, as 23...Qxh2? loses to 24.Bxe6+.

Dec-04-16  YouRang: <Steve.Patzer: What happened to chrisowen?>

He seems to have transcended to a higher level of mysticism.

Dec-04-16  Boomie: ->

Uh oh. Somebody broke <chrisowen>.

If there's anyone left who doubts that <chrisowen> is a bot...

Dec-05-16  PJs Studio: 24...Nc3(!!) Give me a break! That is OUTstanding! A difficult to see Mate in seven. Vicious.
Apr-02-21  SpiritedReposte: How bout <29. ...Qd1+> 30. Bc1 Qd3#
Oct-01-21  Gaito: This game is very nicely commented by Leontxo García in his interesting Youtube channel (in Spanish). The link is the following one:
In that video Leontxo commented that Black could have made the sacrifice 16...Bxh2!! one move before, instead of playing 16...Bd7?! first. Actually that is also what Stockfish 14 says: 16...Bxh2!! has an evaluation of -6.19. See diagram below:

This was White's last chance to prevent the upcoming sacrifice ...Bxh2!! Obviously White did not suspect that such a sacrifice was possible. The Japanese shogi master missed it on move 16, but now he realized that it was his chance.

If White had played now 18.fxe4 instead of capturing the a4-Bishop, he could have averted the upcoming attack, but chess lovers would have lost the chance to witness this brilliant game.

On 19.fxe4 Bg3+ 20.Kf1 Qxd4 and mate in three.

Oct-01-21  Gaito: Information found in Wikipedia:
"Yoshiharu Habu is a professional shogi player and a chess FIDE Master. His master is Tatsuya Futakami. He is the only person to simultaneously hold seven major professional shogi titles at the same time and is also the only person to qualify as a lifetime title holder for seven major titles".
Oct-01-21  Gaito: There seems to a certain similarity between Yoshiharu Habu and the Tartar master Rashid Nezhmetdinov (1912-1974) who was a checkers champion, but learned to play chess when he was 16 or 17 years old, and quickly grasped the essence of chess and became a chess grandmaster and Chess Champion of Russia, playing chess with a very creative and original style with lots of surprising and brilliant sacrifices and unexpected combinations.
