Well of coruse it depends on your experience level with probems. First think is to notice your own king is in mortal danger. This tells us we much check, probably non-stop unless we can deflect some of the attackers. There are three checks. e7-c6 d4-e6 d4-c6. e7-c6 ought to present itself first, because we can see that after it moves, the f6 bishop is miltiply attacked. Still we look at the others. d4-e6 looks bad. It helps to cover up the f6 weakpoint we saw by letting the capturing rook defend it. d4-c6 can't be better than e7-c6 because it could be played later anyhow, and it doesnt' expose the f6 weakpoint as quickly. It also leaves the possibility that maybe if we can deflect enough attackers, the knight could keep the king safe for just one move. So d4-c6 can't possibly be better than e7-c6. So, we should pick up on e7-c6 pretty fast, and there's a few forced moves after that, then things clarify. It's only interesting on here because i think a good problem solver ( i'm only so-so a high A weak expert player ) may get it faster than a machine because of feature recognition. dave
