Only wondering if I should play b3 or g3 first. Deciding on g3, because the B on h1 is undefended. Mentally marking undefended pawns too. } { [%csl Bh2,Ba2] [%clk 0:15:00] } (1. g4 { glbert: Perhaps g4? Technically that pawn can move two squares. But now there's three undefended pawns. } { [%csl Bg4,Bh2,Ba2] }) 1... g6 { [%clk 0:15:00] } 2. Nc3 { [%clk 0:15:06] } (2. b3 { glbert: Don't want to play b3 righ away, since I would like to castle queenside. Castling kingside does not look like an option. } 2... Bxa1 3. Rxa1) 2... c6?! $146 { [%clk 0:14:34] } 3. b3 { [%clk 0:15:01] } (3. O-O-O { glbert: Maybe castling first was better. But I can't help myself, I have to play both g3 and b3 in a starting position like this one. } 3... Ne6) 3... Ne6 { [%clk 0:14:05] } 4. O-O-O { [%clk 0:14:55] } (4. a4!? { Would have been an interesting alternative, preventing the game continuation. }) 4... b5! { A surprising move hinting at the fact that White's Ba1 is undefended. } { [%clk 0:13:43] } 5. Nf3?? { glbert: Preparing d4. } { [%clk 0:14:24] } (5. Bb2 { glbert: Wondering about Bb2 or Kb2 for a couple of seconds. But it seems so early for moves like those -- what is this, move 15? }) 5... b4 $19 { Wins a full piece. } { I call it a sacrifice. } { [%clk 0:13:17] } 6. d4 { glbert: Let's go ahead with d4 anyway, trying to get a nice center in exchange for the piece. Additionally, I am hoping to annoy the black King later on. } { [%clk 0:13:43] } 6... bxc3 { [%clk 0:13:09] } 7. Bxc3 { [%clk 0:13:43] } 7... Nf6 { Objectively not a mistake, however after Whites 8.e4 the position becomes a bit unpleasant. A safer move might have been 7...d5 } { [%clk 0:12:13] } 8. e4 { [%clk 0:13:09] } 8... d5 { [%clk 0:11:23] } 9. exd5 { [%clk 0:12:16] } (9. e5 { glbert: I am tempted to try and close the Black bishop out, but the bot can simply play Bg7 and h6 at some point. Additionally, I am thinking an open center is actually better for me. } { [%cal Bh8g7,Bg7h6] }) 9... cxd5 { [%clk 0:10:27] } 10. Ba5! { Prevents the Black king escaping. Black needs to defend precisely now if he wants to win. } { I was thinking about this move for almost 4 minutes -- certainly too long in a 15+10 game. } { [%clk 0:08:22] } (10. Qe5 { glbert: gets me nowhere. }) (10. Ne5 { glbert: is my other reasonable option, but I would rather free the c3-square for my Q. Additionally, } { [%cal Be1c3] } 10... Nd7 { gets rid of the N quickly. }) 10... Ne4 { [%clk 0:09:48] } 11. Ne5 { glbert: At least now Black has to give up the B for my N. } { [%clk 0:08:06] } 11... f6? { Black not calculating far enough. One half move later he realized his mistake. } { [%clk 0:09:38] } (11... Bxe5! { Black should remove the knight immediately. } 12. dxe5 Qc6 { And with the Black Queen helping the position should hold. }) 12. Bxe4 { glbert: That N was controlling c3, so it has to go. } { [%clk 0:07:47] } 12... fxe5 { [%clk 0:09:14] } (12... dxe4? { Doesn't help: } 13. Qc3+ Kb7 14. d5! fxe5 15. dxe6 $18 { [%cal Gd1d7] }) 13. Qc3+! { Suddenly the position is very unclear. } { Yes, unclear. Against a human opponent of my level I would have thought that I am likely better here. Against a bot, I was thinking I was probably way worse but could still have some fun before inevitably getting mated. SF claims about -0.3, so I guess I was right on both counts? Again I was spending almost 3 minutes here, calculating the few options Black has here. } { [%clk 0:05:09] } 13... Qc6?? { Once again Black calculates one ply too short. } { [%clk 0:09:13] } (13... Bc6! { Was better: } 14. Bxd5 Nxd4! 15. Rxd4 exd4 16. Qxc6+ Qxc6 17. Bxc6 $15) 14. Bxd5! { glbert: Black can't move the Q anywhere save, and taking on c3 is not great either (see below), so this has to be a good move, right? } { [%clk 0:04:45] } 14... Nxd4!? { An interesting shot, sadly not quite good enough. } { [%clk 0:08:33] } (14... Qxc3? 15. Bxe6+ Kb7 16. Bxc3 $18 { glbert: I am very proud that I calculated this exact line. I am suddenly 2 pawns up, have better structure and a safer K. }) 15. Rxd4 { [%clk 0:02:25] } (15. Bxc6 { Also wins: } 15... Ne2+ 16. Kb2 Nxc3 17. Bd7+! { Zwischenschach } { glbert: Nice, I missed this. } 17... Kb7 18. Bxc3 $16) 15... exd4! { [%clk 0:08:27] } (15... Qxc3? { Doesn't work: } 16. Be6+! { glbert: I saw Be6+, and again, I am very proud. } 16... Kb7 17. Rd7+! Kc6 18. Bxc3 $18) 16. Be6+! { glbert: Again I am using too much time on the next couple of moves. In retrospect, these are the only moves that really make sense, so why spend a minute or so on them? The answer is of course: The bot didn't spend any time thinking, and I am not quick enough to do the same. } { [%clk 0:02:28] } 16... Kb7 { [%clk 0:08:28] } 17. Qb4+! { [%clk 0:01:47] } 17...

Qc5+ { [%clk 0:00:52] } 20... Ka6 { [%clk 0:08:19] } 21. Re1! { glbert: I have a simple plan of threatening to bring my R into the attack. And in my experience, good things happen to those who threaten stuff. } { [%clk 0:00:31] } (21. Qxe7 { glbert: Grabbing a pawn, but I don't think I am better here. Black will probably just start chasing my Q around, activating pieces. And frankly, those B in the corners looks scary as is. With 30 seconds on the clock, I would rather have a bit of initiative than a pawn. }) 21... Bf6?? { glbert: I do not understand that move -- if I wanted to take the pawn I would have done so on the last move. } { [%clk 0:08:19] } (21... e5 { was necessary to deny the entry of the White rook. White can still try to open the e file with } 22. f4 { however Black can just ignore that and let White capture on e5 with a pawn while still keeping the e file closed. }) 22. Re6+! { [%clk 0:00:23] } 22... Rb6 { glbert: Would you believe that I missed Rb6? I thought Black had to go } { [%clk 0:08:21] } (22... Kb7 { after which I intended to play } 23. Qc6# { In fact, I already went into the confessional booth right after 22.Re6+, celebrating and taunting MVL. }) 23. Qc4+?? { Crumbles under the time pressure. } { Absolutely. Here I am thinking that I will have a perpetual at best, and I cannot see one. I did look at } { [%clk 0:00:14] } (23. Qa3+ { won on the spot. } { But after } 23... Kb7 { glbert: I missed the follow-up } 24. Rxe7+! { glbert: Right after the game I claimed I would have found it in a longer time control, but looking at it a day later, I am not so certain. } 24... Kc8 (24... Bxe7 25. Qxe7+ { [%cal Ge7f8,Ge7b7] }) 25. Rxa7 $18) 23... Kb7 { [%clk 0:07:51] } 24. Qd5+?! { glbert: I admire people who can still play reasonable moves in bullet. With 20 seconds on the clock, I play the first check that I can find. } { [%clk 0:00:22] } 24... Kb8 { [%clk 0:07:53] } 25. Rxb6+ { [%clk 0:00:17] } 25... axb6 { Now Black simply has too much for the Queen. } { [%clk 0:07:46] } 26. Qb5 { glbert: Making almost random moves now. 10 seconds increment is not enough for me to come up with anything constructive, so I am trying to keep my Q close to the black K, while attacking *something*, pieces, pawns, kings -- it's all the same to me. } { [%clk 0:00:20] } 26...

Kd6 followed by Bf3 is a deadly threat. } { [%clk 0:06:55] } 32. b4 { [%clk 0:00:17] } (32. c3 Bxc3 33. a4 e4 { doesn't help. } { [%cal Ge4e3,Ge3e2] }) 32... Kd6 { [%clk 0:06:54] } 33. Qg8 { glbert: I almost lose on time here (0.7 seconds left), because I cannot come up with a move. The worst thing about this is that I did not even see the mate threat and spent my 20 or so seconds worrying about the central pawns. With Qg8 I wanted to get behind them, and maybe start checking the K again. Very happy that I managed to move in time, ending the game with check mate is way more satisfying. } { [%clk 0:00:11] } 33... Bf3# { 0-1 Black wins by checkmate. } { [%clk 0:06:54] } 0-1
