I have enough on my plate without wondering what joke post has backfired.
Hi Schach
My comment
" Most would be happy coming out of the opening as Black with this."
Meant OK. You have made a minor slip but don't dwell on it.
Pick yourself up and play the cards the you have dealt yo ...[text shortened]... l because chess history dictates that blunders,
no matter how small, often come in two's.)
I agree, the reaction is key. In this case, it's rational to hold myself to standards appropriate to my rating and experience, not to mention a failure in the application of my method: I should not have overlooked such a simple tactic. The fact that the blunder would "merely" have taken me from a superior position to a roughly equal one, doesn't change that. Those who are lackadaisical about such errors are likely to repeat them, not guard against them with renewed vigilance.
As for why I played 8...Bf5 (I'll omit the ?? due to the interesting alternative line you suggested) my notes (made while playing) are rather long, but here are some excerpts:
Another idea is 8...Bf5 which develops another back rank piece, and simultaneously prevents both 9.d4 and 4.e4. (This raises the question of what would have happened if White had played 8.e4. He may have been reluctant to open up the center with his king uncastled, though I'm not convinced that this was unplayable after 8...dxe4 9.o-o-o (not 9.dxe4?).
. . .
I really don't think that I want to play a move that allows 9.e4; at that point Black can choose from 9...dxe4 10.Rd1; or 9...d4 10.Bd2 closing the center; or 9...dxc4 when the c4 pawn is covered by the king's bishop and the f5 square is off limits, and Rd1 looms again. Leaving the pawn where it is isn't an option because of 10.cxd5 winning a pawn, driving the c6 knight to a bad square (or one where it can be immediately captured and the exchange serves no purpose for Black), and cramps Black's center and queenside; not to mention the possibility of d4 (after Nf3) undoubling White's pawns and giving White a full pawn center -- quite a turn-around.
After 8...Bf5 9.Qb3 Rb8 White is still not able to play 10.d4 for reasons detailed above (i.e., without losing a pawn at minimum and/or opening up the e-file). 10.Rd1 and Black cannot move the queen off the d-file without losing the pawn on d5 since the knight on f6 cannot recapture due to the White queen's support from b3; on 10...dxc4 11.dxc4 Qe7 12.Bd3 White is actually gaining ground. On 9...b5 10.cxd5 Rb8 11.Qa4 Black has lost a pawn and has no immediate prospect of regaining it, and the knight is evicted from c6. On 8...Qe7 9.e4 dxe4 10.dxe4 Rd8 11.Rd1 Be6 12.Bd3 White will follow with Nf3 and o-o.
But perhaps it is not necessary to defend the b7 pawn? That loss of tempo is where Black's troubles start. 8...Bf5 9.Qb3 d4 and now:
(a) 10.Qxb7?? and now 10...dxc3 11.Qxc6 cxb2 12.Rb1 Rb8 and White is low on playable options: on 13.Nf3 Bxd3 14.Bxd3 Qxd3 White still cannot castle and the only method of saving the hanging rook is 15.Nd2; and here Black should be wary of 15...Ne4 since the knight on f6 is keeping the White queen out of d5; 15...Rfd8 is the game winning move here.
(b) 10.Bd2 e4!? (to prevent White playing e4) and on 11.dxe4 Nxe4 12.Bc1(?) Nc5! (attacking the queen and defending the b7 pawn since the b2 pawn is now defended by the bishop on c1) 13.Qd1 and White is surely treading on thin ice. Black might consider 13...Qf6 to prevent 15.exd4 and to clear both the d8 and e8 squares for rooks.
If instead on 10...e4!? 11.Qxb7 Qd7 12.dxe4 (12.Rb1 exd3) we have a similar situation.
(c) 10.e4 dxc3 11.Rd1 Qe7 (11.Qxb7?? Qd2# ) 12.Qxc3 Nxe4 wins a pawn (13.Qxb7 c2 14.Rc1 Nd4 (since the knight is hanging and this also protects the c2 pawn) and on 15.Bd3 Rfb8 16.Qa6 Rxb2 17.Ne2 Rb1 and on 18.Bxc2 Nxc2+ 19.Kd2 Rxc1 20.Rxc1 Nxa3 wins the bishop and gets the pawn back, with ...Nxd4 soon to follow and the White king exposed on the open d-file.
In fact, because Qxb7 allows ...Rxb2 infilatrating rooks to White's second rank (another possibility which has yet to be properly considered) it is possible that White may not even play 9.Qb3; what else might he play and what else does he have?
On 8...Bf5 9. Be2 what should Black's continuation be? Black has to remember that his knight on f6 can be taken after ...e4 with Bxf6 and at the moment the only recapture possible is ...gxf6; 9...Qe2 to discourage 10.Nh3; 10.Nf3 and 10...e4 is met with 11.Bxf6 gxf6; should Black be concerned about this recapture or look at it as an opportunity to get rooks on the g-file? 10...d4 (the knight and bishop are attacking the singly protected e5-pawn) 11.Bd2 dxe3 12.Bxe3 e4 and now on 13.dxe4 Bxe4 and if 14.Rd1 Qg4! threatening ...Qxg2 and attacking the rook, while the White queen remains under attack also.
This, however, is only one speculative line and Black has not begun to look at alternatives. Going back to my original reasoning, I don't want to see White play e4 (just because he didn't see it last move doesn't mean he won't play it this move) and the move also prevents White from playing an immediate d4.

All of which doesn't even begin to address White's most obvious response, 9.cxd5 and the simple fork it allows: this is why I called the oversight a ghastly blunder, and why I'm not far off the mark in doing so, since I can't say that I saw your alternative line, never even having considered the initial problem. The fact that I had spent a lot of time looking at other lines doesn't excuse failure to complete my analysis, instead of playing Hope Chess and rushing in. (Again, I was also depressed over money worries at the time.)
