When should you play aggressively with pocket pairs and when is it better to be cautious? How do you know if your pairs are suitable for a raise or a call? Is there a difference in play at different stages of a tournament?
It is better to play small pairs cautiously, and strong pairs aggressively. Play according to the odds and take the position into account. In tournaments, the approach may be different. Try different strategies in tournaments at http://www.optibet.lt/poker.
