Whilst I think we all agree 3-3 invasion under a 4-4 on move 2 is not a good move, the timing of 3-3 invasions is an incredibly deep and difficult subject and one I suspect some people may have a misplaced "that must be wrong" attitude. I know I certainly did when I was weaker. The standard 3-3 invasion joseki is one of the first many people learn, and we also learn that on an empty board the thickness is better than the territory.

However, I think I took this advice on board too much, because as I got stronger, say 5k to 2d, one of the things I noticed was it was a good move to invade at 3-3 earlier than I had previously thought. For example, one principle is that if the hoshi stone makes 2 low far extensions, it is often a good idea to 3-3 right away (if black gets to play another move to secure the corner you can no longer easily get an alive group in sente in black's framework, but will get a weak group that gets attacked for profit). This is because whilst one of the extensions ends up decently placed, the other (

) is badly placed.

If the extensions are high, it's probably not so bad for black:

This confused me for a long time, and still does a bit to be honest. "Doesn't invading at 3-3 when black already has an extension in place make it even better for black than on the empty board?" I wondered. But the answer is no, not if that extension is inefficient and too close. In the diagram above,

is rather poorly placed as it's undercut, and whilst

is in the right direction from the wall, there is an argument to be made it is too close to the wall. (All these discussions are based on white not passing but actually having some efficiently placed stones on the other half of the board, which does of course affect things a bit). If black got to make an extension after white had taken the corner, one line further would be better.

This one line further idea I was taught by Guo Juan 5p. However, when I told it to Charles Matthews 3d (some may know him from being a prolific contributor to Sensei's Library in years gone by and as an author of a few Go books, he spends most of his time on Wikipedia now) without saying "Guo said so" he was rather dismissive of the idea. I do think Guo is right and one line further is better, in fact maybe even further away is better. Using the proverb "extend one more space than the size of the wall" we can imagine the wall is 6 high and, on average, probably on the 4th line:

If there is a friendly 4-4 stone in the parallel corner to the wall, Guo said

is a nice shape which makes an efficient extension from the wall and has a good relationship with the corner.

Maybe black would play
a and think "Haha! it's like I made a san-ren-sei and you played the 3-3 too early you fool, good for me!". But in fact maybe
a, whilst a good move, is not the best and
b would be better so as not to play too close to the wall. Of course some move like an extension or approach on the left is another option.
In conclusion, whilst I can understand the annoyance of someone playing odd moves, particularly in a blitz, I would caution against thinking you have nothing to learn from such games and it is quite likely you will make some mistakes too yourself in the unusual situations that result.
