For Geoff Chandler (one swindle)

[Christopher Kreuzer]

Geoff, as you suggested, I'm posting the third game from that 'swindles' thread in its own thread. It is the one that already has annotations, probably too many, but this was one of those rare games where you clutch at straws and something does come up, somehow. It's an interesting example of an unintentional double bluff. The 'stalemate' line actually allows mate, but the stalemate bit in this case distracted from the mating bit, so it served its purpose of prolonging the game in the hope that something else would come up (the fact that neither player saw the mating line doesn't really change the effect). PS. Have you tried posting a game here with annotations and variations? It's not as easy as I'd hoped it would be. I'll say more in the technical support thread.

3) Drawing by allowing mate in 7

It turns out the move I played allows mate in 7 in the main line, but it was probably the best practical chance.} 44.Be3 Rc3 (44...Rxe3 {my opponent rejected this, presumably seeing the same stalemate line as I did, but he should have looked further and seen the mate that I missed (and clearly he missed as well).} 45.Qxe3 Qb2+ (45...Qxe3{??} 46.Rxg7+ Kh8 47.Rg8+ Kh7 48.Rg7+ Kxg7 {stalemate}) 46.Kg3 Qg2+ 47.Kf4 Qg5+ {I'd only looked at Qg4+ and Qh2+...} (47...Qg4+ 48.Ke5{-+} {due to the three pawns for the exchange}) (47...Qh2+ 48.Qg3 Qd2+ 49.Ke5 {I'd looked this far and thought White was OK, but...} 49...Qd5+ 50.Kf4 Qd6+ 51.Ke3 Qxg3+ 52.Kd4 Qxc7{-+}) 48.Ke5 Qf6+ 49.Kf4 Qd6{#}) 45.Rd7 Rc2 46.Bd2 Qb2 (46...Qf3 47.Qg1 Rxd2+ 48.Rxd2 Qh5+ 49.Kg3 Qg5+ 50.Kf2 Qxd2+ 51.Kg3 g5{-+}) 47.Qf4 {hoping he might miss the obvious threat of Qxh6+ (yes, I was clutching at straws, but had been for several moves).} 47...Qf6 48.Rd6 Qf7 49.Qh4 Qc7 50.Qg3 Rc6{??} {My opponent blunders and allows me a perpetual. He clearly missed the threat of Qg6+, possibly because the focus had been on g7 for so long. He also wrote down Qc7 on his scoresheet (twice) instead of Rc6, possibly he was distracted by me having only a minute left for 15 moves before move 60. It hadn't been a conscious strategy to run my clock down, but maybe it helped. It might seem strange that simple variations like this are missed, but at this level, after four hours of play, it seems quite a lot of things can be missed, as I would demonstrate in my next game the following day...} 51.Qg6+ Kg8 {I was so short of time that I just bashed out the check here, and it was only when my opponent slumped in his chair that I looked again and saw the perpetual! I even spent 20 seconds looking for a possible win, but then offered a draw after the next move.} 52.Qe8+ Kh7 {White offered a draw and Black, in a state of some shock, agreed.}

Thanks. Carl should give us own forum.

I liked the notes in the King march thread better. More chatty.
