My official dutch rating has now become 1761. Due to the sluggish processing of ratings 7 games of a tournament aren't included (+4 =2 -1). If I include those games I come to a virtual rating of 1806!
It's quite difficult to find all the keys in a complex position.
The diagram below is the second problem of the masterlevel problemset I try to solve. (George Renko, CD Killer moves). It shows quite well what the point is. I investigated 7 candidate moves and only the last move was correct. I have investigated the position for half an hour and allthough I know the solution I have no idea what this position is exactly all about.
White to move.
There is a lot going on in the position. But even when solved, most things aren't evident. I find it hard to formulate a narrative.
Only after I have formulated that, the real problem starts:
- What scanmethod do you need to present what was now my last candidate as the first candidate?
- Right now I scan for convergence and targets. What else do I need to scan to identify all important issues of this position?
- There is so much going on that my short term memory is overwhelmed and stalls. The only solution can be to automatize some tasks. Which ones?
After 1.5 total analysis time I managed to identify the main themes that dominate this position:
- White is a piece up
- Ne4 is under threat
- Black threatens Rb8
- Nd4 is pinned
- Removal of Bf1 activates battery Rd1-Nd4
- Black queen has little space
- convergence: b5, f6, d8
- potential targets: N, Be7, Bc6, Rh8, Q, K
The funny thing is that you put your bishop on a convergence square.
