Ben Johnson’s superb ‘Perpetual Chess Podcast’ includes a variety of advice on how to improve, and given the range of interviewees, this advice is often contradictory:
i. Focus on endings – this will have the biggest impact on your results, as you will convert promising positions and save worse ones.
ii. Focus on tactics – you will find opportunities throughout the game that your opponents will miss.
iii. Focus on openings – computers make it easy for your opponent to out prepare you, and extensive knowledge in a range of lines will enable you to spring traps of your own.
I am an adherent of the third option, not because I think it's the best way to improve my chess, but because I enjoy it. IM Kaare Kristensen describes enjoyment as the tenet of chess improvement, which is advice I think we can all appreciate.
Preparation for a game can reap benefits at all levels, and over the last few months I have come to believe in the value of surprise. If you play the same variation of the Sicilian Dragon week in, week out, your opponent has a clear target. Conversely, whilst springing surprises can undermine an opponent’s prep, and give a psychological advantage, it will be for naught if you don’t understand the resultant positions. With this in mind, I wanted to explore different types of opening surprise, and summarise the advantages and pitfalls of each.
There are two types of opening preparation that are guaranteed to surprise your opponent. The first, and most dramatic approach, is to play a move that you know they won’t have seen before, such as:

{[%evp 0,9,29,29,75,23,16,29,27,5,17,-7] There are two types of opening preparation that are guaranteed to surprise your opponent. The first, and most dramatic approach, is to play a move that you know they won't have seen before, such as: ---} 1. d4 f5 2. Na3 $5 {This move doesn't appear in databases (unlike moves such as 2 a3, 2 Bd2 and 2 Qd2, for some reason – check the Livebook in the replayer below). If your opponent rarely varies their openings, the odds of you being able to play a novelty like this are very high. This particular move has two advantages: the knight will find a home on c2 (or e5, if your opponent is very compliant); and White is not worse. --- The biggest disadvantage is that there's no way of engineering a critical position, and that White's best options divert into more familiar territory.} Nf6 3. Nf3 e6 (3... d5 {makes sense for Stonewall players, preventing Nc4. Then} 4. Bf4 c6 (4... e6 5. Nb5 Na6 6. e3 c6 7. Nc3 { is slow, but pleasant for White;} (7. Z0)) 5. e3 e6 6. c3 {;} (6. c4 Bb4+ { is irritating.})) 4. Nc4 d6 (4... d5 5. Nce5 {justifies White's bizarre approach.}) 5. Bf4 {. White once again goes for a London System, and kicking the weird knight with ...b5 will be positionally risky, as it creates a useful pawn hook.} *

I think this kind of surprise can work well, but only if you’re comfortable in a range of positions. With this in mind, there is a more pragmatic approach to opening surprises...
The personal finesse involves sticking to your basic repertoire – which your opponent has likely prepared for – but to play an early finesse. This is the easiest to learn in the hours before a game, and the option with the least risk, as you are likely to have a base knowledge of the lines.
