I just lost a totally winnable match only because boots exist. We were on the last month of spring, I was way ahead on score. Both opponent and me had 4 cards left in hand. Opponent went second. I already played one asmug, so chanches of they having the other one plus boots are low. But low is not zero. Chances of they having 2 boots are low. But low is not zero. So I am forced to make the suboptimal play, going all in 2 seasons earlier, just because the card exists. The result? Opponent didn't have boots, but since I already went all in, they could know my final score beforehand and sinergize their remaining cards optimally to take the lead. Trusting in the odds of they not having boots just seems as wishful thinking. I feel like there is not reliable strategy to beat this game.
