I think a close game is always tense. The most stressful is to have a 1 goal lead for me. This is because all the pressure is on you and your team to perform and not let it slip away because it will forever be known as a choke. Tie games would be the next most stressful. One wrong move and the other team gains an advantage that could be game/series deciding. Playing from behind is always the least stressful. When I have been in this position, there is no pressure. The other team has all the pressure to not choke and I can go all out to try and make that happen. Come from behind wins are always bonus wins anyway. The game is never just decided in the last second. There are always missed opportunities earlier in the game that should be considered but in the moment all anyone can think about is what happens at the end of the game because that is the last memory you get.
