In a game with a time limit of 1 minute, no increment, you have to rely on a quick assessment of the board. It helps if you have had similar positions in past games, if you are familiar with relevant strategic and tactical themes, and if you have confidence in your ability to make your way through a complicated game.
angelcamina demonstrates.

7.Qd5+ Kf8 8.Qxc5+ d6
angelcamina has also faced 8...N8e7 in angelcamina- southerngumbo, 1 0 bullet, lichess.org, 2019 (1-0, 40) and angelcamina - Claim1, 1 0 bullet, lichess.org, 2019 (1-0, 31).
He met 8...Qe7 in angelcamina - mustapha1996, 1 0 bullet, lichess.org, 2019 (1-0, 32).
9.Qe3 Nf6 10.O-O
A small improvement over 10.Nc3, which he played in angelcamina - JsFlexWay, 1 0 bullet, lichess.org, 2018 (1-0, 19)
10...Qe8
On the other hand, this is not quite as strong as 10...Ng4 that angelcamina faced in angelcamina -Kvngmicky, 1 0 bullet, lichess.org, 2019 (1-0, 38) and angelcamina-Cubigami, 1 0 bullet, lichess.org, 2019(1-0, 27).
11.Nc3 c6
Designed to keep White's Knight of d5, but he would have been more prudent to castle-by-hand.
12.f4 Ng4 13.Qg3 h5
14.h3 Bd7
A bold idea, and somewhat of an explanation why he did not castle-by-hand - he wants to use his Rook on a hopefully opened h-file. Will it succeed? Will White defend adequately? In bullet games, anything can happen.
15.hxg4
Taking the piece, trusting in his attack on the enemy King.
15...hxg4 16.d4 Qe7
17.e5
White judges that it is time to break in the center. His preparations also would allow for 17.f5!?, which is sharp, if complicated, winning another piece.
17...d5
Stockfish 10 recommends, instead, that Black continue with pressure on the Kingside, i.e. 17...Nh4 18.f5 Nxf5 19.Qxg4 Kg8 20.Bg5 Qf7 21.Rae1 Qh5 22.Qxh5 Rxh5 23.Bf4 Nxd4 24.exd6 Ne6, when it is not very concerned about White's extra, passed pawn.
18.f5 Nh4 19.Qxg4 Ke8
He could have tried, instead, to hold on by giving up two pieces for a Rook and a pawn, with 19...Nxf5 20.Rxf5+ Bxf5 21.Qxf5+ Kg8. White would still be better, but it would be a complicated win to achieve.
White now wins the offside Knight, and concludes the game quickly.
20.Bg5 Qb4 21.Bxh4 Qxb2 22.Qg6+ Kf8 23.f6 Qxc3 24.fxg7+ Kg8 25.gxh8=Q+ Kxh8 26.Bf6 checkmate
The following game has another example of an "automatic" pawn capture that would have benefitted from a bit more reflection before appearing on the board - but, playing at one minute a game, with no increment, there is a limit to the amount of reflection that is available.

9.Qe3 Nf6 10.O-O
White played Nc3 first, in angelcamina - JsFlexWay, 1 0 bullet, lichess.org, 2018 (1-0, 19).
10...Ng4
"Amazing how popular this move is" - Cliff Hardy.
11.Qf3+ Qf6
A bit stronger than 11...Nf6, as in angelcamina - Kvngmicky, 1 0 bullet, lichess.org, 2019, (1-0, 38).
12.Qg3 Kf7 13.h3 N4e5 14.f4 Nc6
15.e5
Excellent bullet psychology. This is not the strongest move in the position, but if Black automatically captures the pawn, he is busted.
15...dxe5 16.fxe5 Ngxe5 17.Rxf6+ gxf6
White has a Queen and a pawn for a Rook and Knight. More importantly, Black appears to be shaken.
18.d4 Nc4
White finishes up after this, by placing his focus on the enemy King.
19.Qb3 N6a5 20.Qf3 Nd6 21.Bg5 f5 22.b3 Rg8 23.h4 h6 24.Qh5+ Kg7 25.Qxh6+ Kf7 26.Qf6+ Ke8 27.Qe7 checkmate
The Jerome Gambit. Sigh. My favorite chess opening. It has been refuted many times, yet it still comes back to inflict pain on defenders. It might as well be a zombie.
And a fast one, at that. Consider the following 1-minute game as a recent example. (Those of you who are skeptical of the value of bullet games, check out the attending notes.)
angelcamina - JsFlexWay
1 0 bullet chess, lichess.org
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+
The "nudge", always a good move to throw in to make your opponent wonder - what's this? - and use up time.
Kf8 8.Qxc5+ d6 9.Qe3 Nf6
This is a standard position that shows up in The Database over 100 times. The recommended move for Black, according to Stockfish 9, is 9...d5!?, which shows up exactly zero times in The Database.
10.Nc3 Be6
When this move is paired with ...Nf6, it frequently spells mischief. (Guess which move Stockfish 9 still prefers?) This is a nuance that a Jerome Gambit player would note quickly.
11.O-O Kf7 12.f4 Ne7 13.e5
Or 13.f5 Bc8 14.d4
13...dxe5 14.fxe5 Rf8
The way out for Black required a bit of dancing: 14...Nf5 15.Qf4 Nd5 16.Nxd5 Qxd5 17.g4 g6 and the game would be about even, with White's King looking uneasily at an open g-file.
15.exf6 gxf6 16.Qh6 Rh8
A snap judgement to cover the h-pawn, but things now go from bad to worse.
17.Qxf6+ Ke8 18.d3
Wow. Black has a Rook and a Bishop hanging, so White - thinks about development.
18...Bf7
Clearly clock-influenced, but 18...Kd7 would have led to disaster as well.
19.Qxf7+ Black resigned
There is nothing but more misery ahead for the defender.
