Two Pair: Kings and Sevens

In this hand, you played a strong starting hand (Ace of Spades, King of Diamonds) but your decisions weren't fully optimized.

First, your initial raise to 2.5 was reasonable, but considering the aggression from Player 2, a larger sizing of at least 3.5 to 4x the initial bet would have been more effective to build the pot and isolate your opponent, especially with a hand like AK.

When Player 2 re-raised to 10, calling was acceptable given you had a strong hand. However, you should have assessed the risk; facing a sizeable raise often signals strength from the opponent.

After the flop, when you hit a pair of sevens, your all-in bet of 90 did win the hand, but with only a pair, it may have been over-committing. A more moderate bet (around 50-70) could have extracted value while controlling the pot, allowing you to evaluate Player 2's response more accurately.

Overall, focus on adjusting bet sizes according to pot dynamics and opponent tendencies to maximize value in future hands.
