The positional maneuvering that follows is illustrative of Class B level play, as neither side seemingly knows what is going on in the position. Black should be more pleased with the results, as his goal was to maintain equality and get his pieces into more effective positions, rather than attempting to seize the initiative. Black's failure to understand the position's requirements, however, is brought to a head when White undertakes a rather obvious attack on Black's open kingside. Despite the availability of a standard defensive resource (25...Ng8 with equality) Black fails to consider the move. Instead he plays blithely on, focusing on the obvious White threat and failing to do elementary checks, captures and threats (CCT) analysis, leading to a quick and shocking conclusion.
The impression one gets from this game is that neither Black's mind nor heart was in it, which is essentially correct. The opening variation is not very exciting for Black, who needs to struggle a bit for equality with no obvious counterattacking opportunities. Games should not be played on autopilot, however, and in addition to engaging in poor positional play, I was simply lazy in failing to make the necessary calculations when my king position finally came under direct attack.
Any Caro-Kann player should have a defensive radar that detects these types of potential threats to king safety, ideally heading them off before they materialize or, failing that, marshaling enough defensive resources to meet the threat. In this game, the weakening of the king's pawn shield allowed White to muster a cheap attack and Black's failure to find the correct defense allowed it to succeed, neither of which would have occurred if Black had been paying attention to his position.
