!!!!!
Wandering the internet the other day, I ran across a Russian language chess site that teased
Previously, in the precomputer era, often against obviously weaker rivals, we played like this: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7 +?
My computer offered to translate the site to English, and I found it lots of fun.
(There is a link to this web site, as well as lichess.org.)
There is also some cogent advice
...Indeed, the dynamic capabilities of the position are a lot of trouble for Black.Therefore, it is useful to play this beginning against the engine both for whites and blacks - this will definitely contribute to the growth of tactical skill.
The author has done his homework. The infamous game NN - Blackburne, of course, is given, but there is also with Jerome - Brownson, Iowa, 1875; Lowe - Cudmore, corr, 1881; Keeble - Cubitt, Norwich, 1886; Sorensen - X, Denmark, 1888; and even Wall - Bison engine, 2015.
It is well worth a visit.
I have seen computers grind people down, and punish them for tactical oversights. I was a bit disturbed by the King hunt in the following game, too.
It's important to remember: it's not Bill so much as it's the Jerome Gambit, responsible for the loss.
Wall, Bill - Andscacs engine
Palm Bay, FL, 2015
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4 d6
The computers' favorite, the "annoying" or "silicon" defense.
8.fxe5 dxe5 9.Qh3+ Kf7 10.Rf1+
This is a change from 10.Qh5+ as seen in Wall,B - Bison engine, Palm Bay, FL 2015 (1/2-1/2, 67) but it may not be an improvement. The Andscacs engine declines to transpose into that game, and for White there may be an advantage in using the earlier Queen check (at h5), provoking ...g6, before Black's King can retreat to g8, as it does in this game.
10...Nf6 11.Qh5+ Kg8 12.Qxe5 Bd6 13.Qg5 h6 14.Qh4 Qe7
White's King, not Black's, is at risk. Ominous.
15.d4 Nxe4 16.Qxe7 Bxe7 17.Bf4 Bh4+ 18.Ke2
Bg4+ 19.Kd3 Bf5 20.Kc4 b5+ 21.Kxb5 Rb8+ 22.Ka5 Rxb2 23.Bxc7 g6
24.g3 Be7
25.c3 Rh7 26.g4 Bd7 27.Rc1 Bd6 28.Bd8 Nc5 29.dxc5 Bxc5 30.Ka6 Bb6 31.Bxb6 Bc8+ 32.Ka5 axb6+ 33.Ka4 Ra7 checkmate
In the following game the computer was meandering its way toward victory, when suddenly it made an odd move, losing half a point. Machines don't blink, do they?
Wall, Bill - Bison engine
Palm Bay, FL, 2015
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4 d6
The "silicon" (i.e. popular with computers) or "annoying" defense.
8.fxe5 dxe5 9.Qh3+ Kf7
For Bill's experience with 9...Ke7 (which Stockfish 7, at 30 ply, sees as equivalent) see Wall,B - Redom,T, Chess.com, 2010 (1/2-1/2, 59), Wall,B - Qi,H, Chess.com, 2011 (1-0, 14), Wall,B - ubluk, Chess.com, 2012 (1-0, 35) and Wall, B - Guest3551214, 2013 (0-1, 35.)
10.Qh5+ g6
About 1/2 pawn better than 10...Kf8 (in Stockfish 7's evaluation) as in Wall,B - Guest1839713, PlayChess.com, 2013, (1-0, 25).
11.Qxe5
11...Bd4 12.Rf1+ Nf6 13.Qf4 Rf8
13...Re8 was seen in Wall,B - Guest3789034, PlayChess.com, 2013, (0-1,35)
14.c3 Bb6 15.d4 Qe7 16.Qh4 Kg8
Black has castled-by-hand, leaving White with the insecure King. Although Bison has a piece for two pawns, Stockfish 7 sees it as only about 2/3 of a pawn ahead. Bill Wall is creeping up on the computer!
17.Bh6 Rf7 18.Nd2 Qe6 19.Rf4 Bd7 20.Nf3
Or 20...0-0-0!?.
20...Nh5 21.Rxf7 Qxf7 22.Ne5 Qe6 23.Nxd7 Qxd7 24.O-O-O Qf7
25.e5
Bill tests the computer's willingness to pawn-grab, a traditional silicon weakness: 25...Qxa2?! 26.d5!? Re8 27.Qg4!? which looks unclear. The computer declines.
25...c6 26.g4 Ng7 27.b3 Rf8 28.Kb2 Bd8 29.Qh3 Be7 30.Qg2 g5
Black's pieces are finally cooperating, and his advantage is clear.
31.Rd2 a5 32.a4 Qe6 33.Bxg7 Kxg7 34.h3 Rf4
White is battening down the hatches.
35. Rd3 Qf7 36.Qc2 h6 37.Rd2 Rf3 38.Rd3 Rxd3 39.Qxd3 Qf2+ 40.Kc1 Ba3+ 41.Kd1 Qg1+ 42.Ke2 Qh2+ 43.Kf1 Be7
It is not clear what, if anything, Black has gained with its checks, but it probably has not lost anything, either.
44.Qe3 Qb2 45.c4 b6 46.Kg1 Qa2 47.Kh1 Qc2 48.Kg1 Bd8
Bill refuses to crack under pressure. Can the computer find anything to make progress?
49.e6 Qd1+ 50.Kf2 Be7 51.Qe5+ Bf6
This is not Black's best defense - in fact, it leads to an equal game - and it is not clear what the computer missed.
52.Qc7+ Kh8 53.Qc8+ Kh7 54.Qd7+ Bg7 55.c5
White riskily tries for more than the draw by repetition, which he could have forced the computer to find after 55.Kg2, especially after the dangerous 55...Qxb3 56.e7.
55...Qxd4+
An accurate evaluation of the winning response 55...bxc5!? 56.dxc5 Qxd7 57.exd7 Bf6 was probably over both the computer's and the human's horizon.
Now the combatants cooperate to split the point.
56.Ke2 Qe4+ 57.Kd2 Qg2+ 58.Ke1 Qg3+ 59.Ke2 Qe5+ 60.Kd1 Qa1+ 61.Ke2 Qb2+ 62.Kf1 Qxb3 63.e7 Qxh3+ 64.Kf2 Qh2+ 65.Kf3 Qf4+ 66.Kg2 Qe4+ 67.Kf1 drawn
Wow!
