White: N. Christophe - ICCF thematic tournament, 2000
Back in my very first post, I mentioned that my pet lines include the Calabrese Counter-Gambit (2 Bc4 f5!?), Wagenbach King's Gambit (2 f4 exf4 3 Nf3 h5!?), Traxler Two Knights (2 Nf3 Nc6 3 Bc4 Nf6 4 Ng5 Bc5!?), and Schliemann Ruy Lopez (2 Nf3 Nc6 3 Bb5 f5). Subsequent posts have featured two or three of each of those so far – with the exception of the Traxler (aka Wilkes-Barre Variation), so here's one of those now, which also fits into the ongoing Material Imbalances theme.
In the diagram position, the titled piece configuration is only temporary. Black can quickly regain the e4-pawn for a start, while another game (Holzner-Tait) soon reached Queen and Two Connected Passed Pawns vs. Two Rooks and Bishop – which I lost. As it happens I seem to be the only person to lose (and lose twice) as Black from this position, though the other games in the database hardly represent best play either.
Black has tried a variety of moves here: 20...a6, 20...Qh4+ (going for the pawn straight away), and the anodyne 20...Kb7 (my choice). That move looks bizarre to me now. White is getting close to consolidating the kingside and I'm bothered about losing the a-pawn?! Obviously Black should be trying to generate counterplay and, to that end, might consider either 20...h5 (intending ...h5-h4, when 21 Rh1 Qe5 has at least disrupted White's artificial castling) or 20...h6 (probably stronger), followed by ...g7-g5. Houdini marks the latter down as only slightly better for White.
As for 20...Kb7?!, someone else did win with this move (with a bit of help), and in Holzner-Tait 28...h5 (rather than 28...g5?! etc) 29 a4 Qg2 might have offered Black more chances. But in the game below I lost without any fight whatsoever.
In his recent book, Black Gambits 2 (Quality Chess 2012), GM Boris Alterman stops at 18 Nf3 and writes: “Black has no more attack, and White's rook and two pieces will eventually overpower the black queen.” Certainly that proved to be the case in both my games, though whether it's entirely inevitable is not so clear. All the same, the standard 7...Qh4 is probably the right way to go.

White: W. Goedhart - ICCF thematic tournament, 1998
So the queen was unable to compete successfully with three minor pieces in the previous game. How about two rooks and three pawns? That's virtually a +4 point count in the latter's favour. This situation arises in a main line of the Schliemann Defence and is duly assessed as winning for the +4.
In The Ruy Lopez Revisited (New in Chess 2009), GM Ivan Sokolov writes: “Black is too much material behind, without serious chances to create an attack. While White still has to round off the technical part, it is obvious that Black is better advised not to repeat this opening preparation.”
White's mass of material should indeed be sufficient to win. Nevertheless, there are still some practical difficulties to overcome: (i) the rooks are not yet in play; (ii) the white knight is currently a slight liability; and (iii) there are some light square weaknesses for Black to try and exploit.
These factors were all demonstrated in the game below: (ii) Black's 23rd move threatened ...Qg5, forking the knight and g2-pawn; (iii) White's response (24 g3?) made the light squares even more vulnerable; and (i) the rooks never really got into the game at all.
In fact White went wrong straight away. 24 0-0-0 is to be preferred, after which Sokolov concludes: “White had a winning advantage in Todorov-Boudre, Cannes 1997.”
Well, yes, probably. All the same, I think 7...Qd5 is worth an occasional punt over the board. The critical line (up to 18 Ba3!) is a lot for White to remember, supposing they've even looked at it before. From half a dozen games with 7...Qd5 over the years, only one of my opponents has ever got this far, and I won that game too.
