I’d imagine whenever I’ve moved my knight first, my second move would’ve been my usual first move. Therefore after two moves, my pieces would still be in the same position as usual. It has got to be a coincidence that I’ve got a good strike rate opening with it.
It may well be random given the small sample size but I suspect that, a few times at least, you will have done it because my opening move cut off your usual one.

Screenshot the same as what I see, be interested in one that shows the timer you see for my moves.

Re queen loss comment, I'd be interested too but that will have to wait for the next time I have both time and inclination to look back over every game we've played! {8

I'll guess there will be at least 3 games won by someone who lost their queen first and at least one where the loser still had their queen on the board.

If I do look back in that detail I'll be interested in somehow noting how the scoring develops, e.g. first to, say, 5 points etc. (Let's call that a "significant" lead, e.g. at least a minor piece and 2 pawns.) I'd make me at least 1/3 to have taken a significant lead most often and 1/5 to have lost most games after taking a significant lead!

I will get a snap of the timer today.

I think there’s been quite a few games where we’ve lost while still holding our queen. Probably me more so, it’s a bastard losing while still holding valuable pieces.

Yesterday's freak footy results got me musing on probability and how very unlikely events are usually not quite as unlikely as people tend to think! Also I was thinking about how less experienced punters tend to attach too much significance to short term streaks, e.g. 6 match form. It got me musing about long winning streaks for either of us in our chess games, how often they happen and how we react to them when they do. In short, we probably over-estimate the relevance of good or bad form and understimate the extent to which it's just down to pure chance.

Before I share a few stats, I'd be interested in your guesses as to the following. Out of the 149 competitive games we've played to date:

How many times have either of us had 3 or more consecutive wins?
How is that split between the 2 of us?
What's the longest unbeaten run either of us have been on and who was it?

(Obviously this is addressed to Kenbo but anyone else is more than welcome to have a guess!) {8

I did look back at this a few weeks ago, I think when I needed four on the trot to win the series and noticed that neither of us have ever managed it (on this updated app anyway, I think you won the first four games but I haven’t got that in my games) before.

I didn’t count how many times it happened, but I’d guess it’s happened a dozen times, and I will say it’s evenly split.

I think I went seven or eight games unbeaten in one series, so I will say I’m winning that one?

It's happened 14 times, 8-6 in your favour. I did win the first 4 games, which is obviously of no real relevance to where we are now. I did it 5 of the first six times it happened then you did it 6 times without reply. We've both done it once since then.

In terms of unbeaten runs, you're very much the daddy. I've managed 4 games on 3 occasions, that opening salvo of 4 wins and a couple of w-w-d-w sequences. You've managed 4 games twice (d-d-w-w- and w-w-w-d), a 5 (w-w-w-d-d) and a 7 (6 wins with a draw bang in the middle).

Statistically, I think it's remarkable that we've only had the one 4 game sequence and nothing longer, having played this many games. If you think of a coin toss, the odds of a sequence of 5 the same is only 15/1.

It's made me realise that a long winning run for one of us isn't as significant as it seems, being more down to luck than we credit it with at the time. Obviously we should see if we're making the same mistake or if our opponent is doing something that we need to respond to but the chances are it's just about who has made the fewest basic errors, or made them at the worst time.

Easier said than done but I'll try and remember that next time it feels like I can't buy a win!

I think you’re cooking the books saying it’s only 15/1 for a five timer! It’s only that price once you’ve won the first game.

If we were the same price each to win a game, and you add in the draw, what would the odds be? Would that make us both odds on?

No, I'm right (obviously) ;-) but I know where you're coming from. I'm not thinking in terms of the odds of heads coming up 5 times or me winning five games, I'm thinking of the odds of the same outcome (heads or tails, you or me) coming up 5 times. Toss a coin and see which side it lands, the odds of the same outcome happening on the next 4 tosses is 15/1. Start from any given point where either of us has just won a game, the odds of that person going on to win the next 4 games (ignoring the draw) is 15/1. That's the odds of the same outcome (unspecified) coming up 5 times in a row. Obviously the odds double if you specify heads or tails or me/you before the first toss.

With 16 draws in 149 games I've simplified things to say 10% chance of draw so a 90% chance of a result, split equally gives us each a 45% chance of winning any game. That makes the "true" decimal odds 2.22 each and 10 for the draw. On that basis, the odds of one of us, after winning a game, going on to win the next 4 become 24.39. The odds of avoiding defeat for the next 4 games are 10.93.

As I say, it surprises me that there haven't been more instances of either of us winning 4 in a row, or even avoiding defeat 4 or more times in a row.

I should never doubt your figures! :lol

Both of us odds against to win a match, who’d have thought.

As much as you want, but you’ll only be getting 4/5 for each of us!

It could go pay-per-view!

Just when you thought I'd run out of ways to bore you with stats about our mammoth tussle, I've decided to add the dates for each game (just by month for now). So here's how the record looks for each month (total games played, my wins, Kenbo's wins and draws).

May: 23 - 13-8 (2)
Jun: 39 - 20-17 (2)
Jul: 24 - 9-12 (3)
Aug: 33 - 12-18 (3)
Sep: 25 - 11-9 (5)
Oct: 13 - 7-5 (1)

May and (obviously) October are part months, our first game being 5 months ago on 13th May! {8 July was sort of a part month as, when we finished a series we decided to play some "pre-season friendlies" before the next series started on the 1st of August.

Final fun stat, each of the last 3 months has started with a drawn game!

39 games in June! 8]

I’m obviously a better player when the sun is out. That doesn’t bode well for me in the coming months! :lol

I thought I may have fared better than that, I had a hot streak where I won four series on the trot. You’re red hot fav to take the outright lead again though.

Well you had the best month in terms of margin in August, when my daft mistakes were at their peak. I took the first 3 series and was 11 in front which takes us to early June, you took the next 3 and levelled the overall score which sees us into early August. Since then we've each taken a series by a single point and I'm now 3 in front in the current series (at "match point") and 3 up overall. So nothing to speak of between us over the last couple of months.
