Why This Move Makes Sense
Take Discard Card Strategy
Taking the 3 and swapping out your 6 gives an immediate score reduction of 3 points without risking drawing a higher card.
High Pair Protection
You have two 10s in Column 2. We avoid breaking this pair because opponents frequently discard 10s, giving you a strong chance to complete a triple and zero out the column.
If You Draw From Deck Instead
Average unseen deck card value is ~4.2. Drawing is only recommended if the discard card is higher than ~4.
