Choose: Pawns or Piece?

In the following game White chooses to play with the pawns vs Black's extra piece in a Queenless middle game. The second player cannot figure out how to break through, and eventually settles for returning the extra material, ending up in a drawn Bishops-of-opposite-colors endgame.

White has two pawns for his sacrificed piece. He plans to patiently test his opponent. That is a bit of a feat in a 3-minute game.

Black's chances have come and gone, and his last attempt is to return his extra piece, arriving at a drawn endgame.

Not Right Enough

Sometimes, it seems, you can do almost everything right - and still not be successful.

In the following Jerome Gambit game, Black counter-attacks while securing the safety of his King. When White's pawns get too frisky, he returns the sacrificed material and transitions to what looks like a draw-able endgame.

And then he loses.

As ever, especially in a 3-minute game, Phiilidor 1792 is a force to be reckoned with.

10.Nc3 c6 11.0-0 Kf7 12.f4 Re8 13.f5 Ne5 14.d4 Nc4

Harassing the Queen with the Knight is a known theme, but probably 14...Neg4 was a stronger way to do it, as in perrypawnpusher - andrecoenen, blitz, FICS, 2010 (1-0, 25) and perrypawnpusher - darqknight, blitz, FICS, 2011 (0-1, 63). 

15.Qf3 Kg8

Curiously, reaching perrypawnpusher - Nadant, blitz, FICS, 2010 (0-1, 59) only with White to move, not Black.

Black has castled-by-hand, and White will soon be ready to get his "Jerome pawns" rolling. The defender still has an edge. 

16.b3 Nb6 17.Bg5 Qe7 18.Rae1 Qf7 19.e5 dxe5 20.dxe5 Nfd5 21.e6 Qf8 

The pawns are beginning to look ominous, so Black returns material.

White's Bishop vs Knight and better pawn position give him a slight edge. He outplays his opponent the rest of the way.

A Whole Lot In There

Chessfriend Philidor 1792 has delivered another large collection of exciting games: some Jerome Gambits and some Jerome Gambit-related openings.

For a three-minute blitz game, the following match has a whole lot in it. White improves on earlier efforts (a dozen or so moves into the game) and carries the fight from the opening through the middle game to the endgame. When his opponent slips, Philidor 1792 executes a piquant checkmate.

Dany Sénéchaud

French chess player, openings explorer and author - Emil Joseph Diemer (1908-1990): missionnaire des échecs acrobatiques - Dany Sénéchaud sent the following game, which opens up more understanding of Bxf7+ in the double e-pawn openings and gives a possible contribution to the lineage of the Jerome Gambit.

Millet,C - Sénéchaud,D
Rochefort, 1995
(notes by Sénéchaud, with additions)

1.e4 e5 2.Bc4 Bc5 3.c3 Nc6!!?

3...Nf6 4.d4 exd4 5.e5 d5 

4.d4! exd4 5.Bxf7+ 

The position after 4 moves, and this sacrifice - reminiscent of the Abrahams Jerome Gambit - is rare, although it goes back at least as far as Philidor, who thought it playable. Could this have been one of the early influences that led Alonzo Wheeler Jerome to his Gambit?? For other ideas, see "Proto-Jerome Gambits?" Part 1 and Part 2 as well as "Godfather of the Jerome Gambit" Parts i, ii, iii and endnote. - Rick


Of course, someone had to try declining the sacrifice, although that can hardly be recommended: 5...Kf8 6.Bxg8 Rxg8 7.Nf3 h6 8.cxd4 Bb4+ 9.Bd2 Qe7 10.0-0 Qxe4 11.Bxb4+ Nxb4 12.Qb3 Nc2 13.Ne5 d5 14.Nd2 Qf5 15.g4 Qh7 16.Qxd5 g5 17.Qd8+ Kg7 18.Qxc7+ Black resigned, Wassilieff,H - Akadegawa,K, email 2000 - Rick
