Thank you for your reply.
What you say makes complete sense.
But whether my opponent does or doesn’t understands a chess position well is an unknown variable to me. The only thing I know about them is their rating, and if their rating is significantly higher than mine, then it’s reasonable to assume they will understand the position better than I, whether it’s a simple p ...[text shortened]... ng; I can’t say I’ve ever done any research to back this up. But this has been my thinking till now.
Your question is about aiming for Type 2 or Type 3 positions against a much stronger opponent.
If you can get into a Type 2 position and are happy (I assume) with a draw, then go for it.
Yet be aware that many positions are deceptively simple. A much stronger player
can keep testing you and making you prove that you do understand all the nuances.
Magnus Carlsen can routinely outplay strong GMs in 'simple' positions.
Against a much stronger opponent, you may decide that will lose if you play 'normally'.
So you may aim for a Type 3 position, going for wild complications that no human
can possibly calculate to a certain conclusion. You probably will lose because your
opponent is better at calculation, but you have a chance of landing a lucky punch.
A much higher rated player may be overconfident and intentionally play dubious
moves to get you 'out of book'. A GM (once ranked in the top 15 in the world)
had White against me and acted like he was going to wipe me out effortlessly.
He did not disguise his attentions of making an early direct attack upon my king.
He sacrificed one pawn, which I accepted (I had analyzed it before) and then offered
a second pawn. I was 'out of book' by then and thought it was too risky to accept.
For his pawn, he developed a moderately strong attack that compelled me to play
accurate defense for about ten moves, but I felt that I never was on a knife's edge.
After his attack petered out, he was a pawn down with no compensation in an endgame.
His only practical compensation was that I had used a lot of time and energy in defense.
With a look of disgust, he offered a draw. I knew that he knew that he was losing.
But I was pretty tired (and had started my day with a slight cold), so I accepted.
Later, my occasional (informal) coach said that I had showed a lack of 'killer instinct'.
He believed that I should have kept playing and really made the GM (whom he disliked) sweat.
