Yes, you can use a counting system without explicitly tracking every individual card. Simplified counting methods like the High-Low system allow you to make general estimations based on the overall trends in the deck, focusing on the relative number of high versus low cards remaining. By observing the cards dealt and adjusting your betting strategy accordingly, you can estimate the deck's composition and adjust your play without maintaining an exact running count. Techniques like focusing on dealer behavior or rough estimation of the "true count" also let you take advantage of deck conditions without counting each card individually. While not as precise as full card counting, these approaches can still offer a strategic edge.
